In order to meet the liquid transportation needs under different working conditions, the design and performance of the liquid pump's regulating device are particularly critical. In the prior art, the liquid pump's regulating device mostly uses a traditional mechanical structure for flow control. However, these devices generally have some serious defects, which limit their effectiveness and universality in practical applications.

[0003] Existing liquid pump regulating devices usually rely on valves or throttling devices to control flow. Although this mechanical regulating method can achieve basic flow control, it cannot achieve precise regulation, often resulting in inflexible flow regulation and inability to adapt to different pipelines. Specifically, since the pump output flow is affected by liquid characteristics and environmental factors, the existing liquid pump requires the entire system to be adjusted when the pipeline is replaced, which not only increases the complexity of operation, but also increases maintenance costs. In addition, valve regulation is prone to improper and flow fluctuation problems, which seriously affect the delivery efficiency. The existing technology uses power-driven components and liquid detection devices to achieve preliminary control of flow, lacking dynamic response to flow changes and fine adjustment capabilities, and the functional components are installed on the delivery pipeline, which makes the disassembly and installation of the pump pipe complicated, which is not conducive to the maintenance and maintenance of the equipment.

[0023] The technical solution of the present application is further explained below with reference to the accompanying drawings and through specific implementation methods.

[0024] refer to Figures 1 to 6In one embodiment, a liquid pump adjustment device includes: a fixed seat 1, wherein a receiving groove 11 with an opening at one end is provided in the fixed seat 1, and a rotating shaft 23 passing through the receiving groove 11; an adjustment component 2, including a rotating structure 21 and an adjustment structure 22, wherein the rotating structure 21 is connected to the rotating shaft 23 and rotates synchronously with the rotating shaft 23, wherein the adjustment structure 22 is connected to one end of the rotating shaft 23 and is relatively fixed to the rotating structure 21, wherein the adjustment structure 22 includes a first shell 221 and a rolling spring 222, wherein a card slot 223 is provided in the first shell 221, and a plurality of the card slots 223 are arranged around the center point of the first shell 221, and One end of the rolling spring 222 extends into the slot 223 and is connected to the rotating structure 21, and the other end is connected to the rotating structure 21 inside the first shell 221. The elasticity of the rolling spring 222 is adjusted by changing the contact point position between the rolling spring 222 and the slot 223 to adapt to pipelines of different specifications; the pump tube 3, half-hole grooves 31 are provided on the opposite sides of the pump tube 3, and circular protrusions 111 corresponding to the half-hole grooves 31 are provided on the inner walls at both ends of the opening of the accommodating groove 11. The pump tube 3 is connected to the fixing seat 1 through the cooperation between the half-hole grooves 31 and the circular protrusions 111, so that the pump tube 3 can be detached and fixed on the fixing seat 1.

[0025] In the above embodiment, the fixing seat 1 can be made of high-strength engineering plastic or aluminum alloy material, which has good corrosion resistance and mechanical strength and can adapt to various working conditions. A receiving groove 11 is provided inside the fixing seat 1, and one end of the receiving groove 11 is open to facilitate the installation and removal of the pump tube 3. At the same time, the rotating shaft 23 is inserted into the receiving groove 11 to ensure that the rotating shaft 23 can rotate freely and provide power support. The adjustment component 2 includes a rotating structure 21 and an adjustment structure 22. The rotating structure 21 is connected to the rotating shaft 23, and the power is transmitted to the rotating structure 21 through the rotation of the rotating shaft 23. The adjustment structure 22 is fixedly connected to one end of the rotating shaft 23 and remains relatively fixed with the rotating structure 21. The adjustment structure 22 is composed of a first shell 221 and a rolling spring 222. A plurality of slots 223 are evenly arranged on the inner wall of the first shell 221. These slots 223 are distributed around the center point of the first shell 221. Specifically, the slots 223 may include a plurality of groups, each group includes a plurality of through holes, and each group of slots 223 is spaced along the center point of the first shell 221 toward the edge of the first shell 221. The spacing distance may be The unequal distance can also be equidistant. By selecting the slots 223 with different distances, the compression degree of the spring can be changed, so as to adjust the elasticity of the spring. One end of the rolling spring 222 extends into the slot 223 and is connected to the rotating structure 21, while the other end is located inside the first shell 221 and is connected to the rotating structure 21. The elasticity of the rolling spring 222 is adjusted by changing the contact point position between the rolling spring 222 and the slot 223, so as to adapt to pipelines of different specifications, wherein the specifications include at least pipelines of different sizes, different thicknesses and different hardnesses, and the pipeline refers to the pipeline for liquid flow. The pump tube 3 is provided with half-hole grooves 31 on opposite sides of the pump tube 3, and circular protrusions 111 corresponding to the half-hole grooves 31 are provided on both ends of the inner wall of the opening of the accommodating groove 11 of the fixing seat 1. The pump tube 3 is reliably connected to the fixing seat 1 through the cooperation of the half-hole grooves 31 and the circular protrusions 111, so that the pump tube 3 can be easily disassembled and fixed. This connection method improves the stability of the pump tube 3. When the user needs to replace or maintain the pump tube 3, the operation can be completed quickly, which reduces labor costs and time consumption.

[0026] In this embodiment, the regulating component 2 realizes stepless regulation of the replacement of pipelines of different specifications through the synergistic effect of the rotating structure 21 and the adjusting structure 22, thereby improving the flexibility of the use of the liquid pump. Secondly, the application of the rolling spring 222 makes the adjustment process smoother, reduces the abruptness of the flow change, and ensures the stability of liquid transportation. In addition, the quick disassembly and fixing function of the pump tube 3 makes maintenance work simple, greatly improving the operability and applicability of the equipment. The entire device is compactly designed and occupies little space, and is suitable for use in a variety of application scenarios, such as liquid transportation and regulation in the chemical, pharmaceutical, food and other industries.

[0027] In a specific embodiment, for example, the current rolling spring 222 is stuck in the nearest slot 223, and the thickness of the adapted pipeline is 4 mm. When it is necessary to replace the pipeline with a thickness of 6 mm, the operator only needs to simply rotate the adjustment structure 22 to move the rolling spring 222 from the current slot 223 to another group of slots 223 to adjust the thickness of the pipeline. Since the elastic adjustment of the rolling spring 222 is achieved by changing the position of the contact point between it and the slot 223, the adaptation of pipelines of different specifications can be completed without replacing any parts. This design not only simplifies the operation process, but also greatly reduces the maintenance cost. In addition, the design of the fixing seat 1 and the pump pipe 3 of the liquid pump regulating device also fully considers the needs in practical applications. The material selection and structural design of the fixing seat 1 ensure its stability and durability under different working conditions, and the matching design of the semi-hole groove 31 of the pump pipe 3 and the circular protrusion 111 ensures the stable connection of the pump pipe 3 on the fixing seat 1, and is convenient for quick disassembly and installation. This design allows operators to quickly complete maintenance or replacement of the pump tube when the liquid pump needs it, without the need for professional tools or complicated operations, thereby improving work efficiency. In summary, the liquid pump regulating device achieves rapid and stepless regulation of pipelines of different specifications through its unique design of the regulating component 2, while ensuring the stability and reliability of liquid transportation. Its compact structural design and simple operation make the device have broad application prospects in multiple industries such as chemical, pharmaceutical, and food.

[0028] In another scenario embodiment, by setting a plurality of slots 223 of different distances, the rolling spring 222 can be clamped on different slots 223, and the main function is to adjust the working state and shock absorption characteristics of the spring, so that the liquid pump can adapt to various different liquid delivery requirements and working environments. For example, in the first scenario, through the slots 223 of different distances, the spring can be locked at different positions, and its initial compression or extension state can be adjusted, and the appropriate spring preload can be set for different working environments. For example: in the environment of high load or high pressure delivery, the spring can be locked on a tighter slot 223 so that it works in a larger compression state to cope with larger vibrations or shocks. In the environment of low load or slight vibration, the spring can be clamped on a looser slot 223 to ensure its flexibility and sensitivity and absorb smaller vibrations. In the first scenario, different liquid delivery requirements may require the pump to operate under different workloads. By changing the clamping position of the spring, the compression and extension stroke of the spring can be directly changed, thereby adjusting the intensity of shock absorption. When high-viscosity liquids or high-pressure liquids are transported, the vibration and impact in the system are large, and the spring can be in a compressed state to enhance the shock absorption effect and reduce equipment loss. In low-viscosity liquids or conventional transport environments, the spring can work in a more extended state to reduce excessive spring damping and improve the operating efficiency of the pump. In the third scenario, different working environments may have different vibration frequency and intensity requirements, and the rolling spring 222 can adapt to these requirements by adjusting the position of the slot 223. The user can select a suitable slot 223 according to the actual transport conditions, so that the spring can work in an ideal compressed or extended state to adapt to a variety of environments. In an unstable outdoor working environment, a tighter slot 223 can be selected to cope with large vibrations and shocks. In a laboratory or precision process, a looser slot 223 can be selected to provide detailed vibration control. In the fourth scenario, different liquids have different physical properties (such as density, viscosity, pressure, etc.), which may have different effects on the operation and vibration of the pump. By adjusting the position of the rolling spring 222, the shock absorption effect of the pump under different liquid transport conditions can be optimized. The flow of viscous liquids will generate larger loads, and the springs will need greater compression force to balance the impact within the system. The flow of low-viscosity liquids can use lighter spring forces to ensure efficient operation of the pump.

[0029] In one embodiment, the rotating structure 21 includes a rotating sleeve 211, a fixed guide wheel 212 and a rolling bearing 213. The rotating sleeve 211 is sleeved on the periphery of the rotating shaft 23, the fixed guide wheel 212 is fixedly connected to the rotating sleeve 211, and the fixed guide wheel 212 is arranged corresponding to the slot 223; the rolling bearing 213 includes a sleeve 214, the sleeve 214 is passed through the first shell 221, and the portion of the sleeve 214 exposed outside the first shell 221 is provided with a through hole, one end of the rolling spring 222 extends into the slot 223 and is connected to the fixed guide wheel 212, and the other end passes through the through hole of the sleeve 214 inside the first shell 221 and is connected to the rolling bearing 213, so as to adjust the elasticity of the rolling spring 222 by the rotation of the rolling bearing 213 to adapt to pipelines of different specifications.

[0030] In this embodiment, the rotating structure 21 includes a rotating sleeve 211, a fixed guide wheel 212 and a rolling bearing 213. The rotating sleeve 211 is sleeved on the outer periphery of the rotating shaft 23 and rotates synchronously with the rotation of the rotating shaft 23, directly transmitting the power of the power source to the entire adjustment component 2. The fixed guide wheel 212 is connected to the rotating sleeve 211, and the fixed guide wheel 212 is designed to be positioned opposite to the slot 223, so that the rolling spring 222 can be stably inserted and work with it, thereby enhancing the stability of the structure and ensuring the accuracy of the adjustment process. The introduction of the rolling bearing 213 includes a sleeve 214, which is inserted into the first housing 221, which not only ensures the stable installation of the bearing, but also provides necessary support for it. The portion of the sleeve 214 exposed to the first housing 221 is specially provided with a through hole. This design enables one end of the rolling spring 222 to be connected to the fixed guide wheel 212, while the other end can pass through the through hole of the sleeve 214 inside the first housing 221 and be closely connected to the rolling bearing 213. When the rolling bearing 213 rotates with the rotation of the rotating shaft 23, the elasticity of the rolling spring 222 can be adjusted through the sleeve 214, so as to adapt to pipelines of different specifications. It is worth noting that in this embodiment, the rotating sleeve 211, the rotating shaft 23, the first housing 221 and the second housing 51 are combined into a rotor, that is, in the subsequent embodiments, the rotor is combined or partially combined with this component.

[0031] In one embodiment, a disassembly component 4 is also included, and the disassembly component 4 includes a hand-held portion 41 and a disassembly buckle 42. The disassembly buckle 42 is arranged on opposite sides of the pump tube 3 and adjacent to the half-hole groove 31. The hand-held portion 41 is connected to the disassembly buckle 42 and exposed on the top side of the pump tube 3; the inner walls at both ends of the opening of the accommodating groove 11 are provided with disassembly grooves 112 corresponding to the disassembly buckle 42, and the disassembly buckle 42 is embedded in the disassembly groove 112. A gap is left between the side of the disassembly buckle 42 connected to the pump tube 3 and the pump tube 3. The hand-held portion 41 is pressed to move the side of the disassembly buckle 42 connected to the pump tube 3 into the gap, thereby releasing the engagement state between the disassembly buckle 42 and the disassembly groove 112, and realizing the disassembly of the pump tube 3.

[0032] In this embodiment, the disassembly assembly 4 includes a handheld portion 41 and a disassembly buckle 42. The setting of the handheld portion 41 allows the user to easily hold and operate, and whether it is to disassemble or install the pump tube 3, it becomes simpler and more direct. The combination of the disassembly buckle 42 and the opposite sides of the pump tube 3 ensures the stability of the connection and makes the disassembly process smooth. The buckle matches the disassembly groove 112 on the inner wall of the opening of the receiving groove 11. When the pump tube 3 needs to be disassembled, the user only needs to gently press the handheld portion 41, and the disassembly buckle 42 will move into the gap, thereby quickly releasing the engagement state with the disassembly groove 112, and realizing the rapid disassembly of the pump tube 3, which not only reduces the difficulty of operation, but also improves work efficiency. The gap left between the disassembly assembly 4 and the pump tube 3 provides sufficient moving space for the disassembly buckle 42, ensuring the smooth progress of the disassembly process. At the same time, the existence of the gap also avoids excessive friction between the disassembly buckle 42 and the pump tube 3, reduces wear, and prolongs the service life of the equipment. In practical applications, the design of this disassembly assembly 4 allows users to replace pump tubes 3 of different specifications or materials as needed to meet different transportation requirements. Whether it is the chemical, pharmaceutical or food industry, you can choose the appropriate pump tube 3 for installation and use according to your actual situation. This flexibility and versatility enables the liquid pump device to perform optimally in a variety of application scenarios.

[0033] In one embodiment, a rotation detection structure 5 is also included, including a second shell 51, a magnetic member 52 and a detection mechanism. The center of the second shell 51 is sleeved on the periphery of the rotating shaft 23, and is arranged on the inner wall of the bottom end of the accommodating groove 11 and connected to the rotating sleeve 211. A plurality of the magnetic members 52 are arranged at a preset distance on a side of the second shell 51 away from the first shell 221. The detection mechanism includes a sensor and a signal processing circuit. The sensor is arranged on the outer side of the second shell 51, corresponding to the magnetic member 52, and is used to detect the rotation information of the rotating sleeve 211. The signal processing circuit is connected to the sensor and is used to receive and process the signal of the sensor.

[0034] In this embodiment, the rotation detection structure 5 includes a second housing 51, a magnetic member 52 and a detection mechanism. The second housing 51 is a core component and is sleeved on the outer periphery of the rotating shaft 23, and is tightly connected to the bottom inner wall of the receiving groove 11 and the rotor, providing a solid foundation for the entire detection structure. The interval arrangement of the magnetic member 52 ensures that a stable magnetic field change can be generated when the rotor rotates, and also enables the sensor to accurately capture these change information. The sensor is installed on the outside of the second housing 51, corresponding to the magnetic member 52. When the rotor rotates with the rotation of the rotating shaft 23, the magnetic member 52 will also change its magnetic field state accordingly, and the sensor can immediately sense this change and transmit the corresponding signal to the signal processing circuit. The signal processing circuit receives and processes the signal from the sensor, converts it into identifiable rotation information, such as rotation speed, rotation direction, etc., and provides reliable data support for the monitoring, control and fault diagnosis of the equipment. The introduction of this rotation detection structure 5 enables the liquid pump equipment to grasp its own operating status in real time, discover and deal with potential problems in time, thereby ensuring the stable operation and efficient operation of the equipment. At the same time, it also provides the possibility for remote monitoring and intelligent control of equipment, taking a solid step towards the intelligent development of liquid pump equipment.

[0035] In a specific embodiment, a plurality of magnets are mounted on the second housing 51, and these magnets are distributed according to a specific rule. A special detection device is provided, which can sense the magnetic field changes of the magnets on the rotor. The detection device may include a magnetic field sensor, a signal processing circuit and other parts. When the rotor rotates, the magnetic field generated by the magnets will be sensed by the detection device and converted into an electrical signal. The electrical signal output by the detection device is processed and analyzed. Through specific algorithms and software, the direction and speed of the rotor can be accurately determined according to the distribution law of the magnets and the detected magnetic field changes. It is worth noting that the magnets distributed according to a specific rule can be arranged according to different polarities and spacings to optimize the sensitivity and stability of the magnetic field changes. For example, the magnets can be arranged in an alternating manner to form a periodically changing magnetic field pattern. When the magnets on the rotor pass through the sensor as it rotates, this periodically changing magnetic field will cause periodic fluctuations in the sensor output signal. The multiple sensors of this embodiment form a sensor array, which can simultaneously capture magnetic field change information from different angles and positions. Through a spatial resolution algorithm, the specific position, rotation speed and direction of the rotor can be accurately calculated. In addition, by adjusting the distance and angle between sensors, the spatial resolution and dynamic response capability of the entire detection system can also be optimized. In addition to magnets and sensors, the signal processing circuit is also an important component of the rotation detection structure 5. The circuit is responsible for receiving the weak electrical signal output by the sensor and performing amplification, filtering, digitization and other processing for subsequent data analysis and processing. In order to cope with complex and changeable working conditions, the signal processing circuit also needs to have high anti-interference ability and stability to ensure the accuracy and reliability of the detection results.

[0036] In one embodiment, the sensor is a Hall sensor, and the signal processing circuit further includes a comparator for comparing the received Hall sensor signal with a preset threshold value, and outputting a corresponding control signal based on the comparison result, wherein when it is detected that the rotation information deviates from the standard value, the rolling spring 222 is triggered to expand and contract to restore the liquid pump to a normal output state.

[0037] In this embodiment, the sensor is selected as a Hall sensor, which is a magnetic induction sensor based on the Hall effect, and has the advantages of high sensitivity, fast response speed, good stability, etc. The Hall sensor outputs an electrical signal by sensing the change of the magnetic field. When used in conjunction with the magnetic member 52, it can accurately capture the information of the rotation of the rotor. At the same time, a comparator is added to the signal processing circuit, which is an electronic component that can compare the magnitude of two voltages or currents, and its output state depends on the relative magnitude of the input voltage or current. Here, the comparator is used to compare the signal output by the Hall sensor with a preset threshold. When the liquid pump device is working normally, the rotation information of the rotor will remain within a certain range, that is, the signal output by the Hall sensor will be stable within the preset threshold. However, in some cases, such as blockage of the pump tube 3, motor failure, etc., the rotation information of the rotor may deviate from the standard value, thereby causing the signal output by the Hall sensor to exceed the preset threshold. At this time, the comparator will detect this change and output a corresponding control signal. The rolling spring 222 can deform when subjected to an external force, and quickly return to its original state after the external force disappears. When the comparator outputs a control signal, it triggers the rolling spring 222 to perform a telescopic action. Specifically, when it is detected that the rotation information deviates from the standard value, the rolling spring 222 will be subjected to a reverse force, forcing it to deform and compress or stretch, thereby changing the position or state of certain components inside the liquid pump. In this way, the expansion and contraction action of the rolling spring 222 can directly or indirectly affect the output of the liquid pump. For example, in the case where the pump tube 3 is blocked, the expansion and contraction of the rolling spring 222 may push a component inside the pump body to move in order to clear the blockage or change the internal structure of the pump body, thereby restoring the normal output state of the liquid pump. This design not only improves the adaptability and reliability of the liquid pump equipment, but also provides users with a more convenient and efficient maintenance method.

[0038] In one embodiment, a plurality of fixed positions are provided on the inner wall of the first shell 221, each of the fixed positions corresponds to a preset elastic coefficient, one end of the rolling spring 222 is connected to the rotating structure 21 through the fixed guide wheel 212, and the other end can be selectively connected to one of the fixed positions, thereby realizing the adjustment of the elastic coefficient of the rolling spring 222.

[0039] In this embodiment, a plurality of fixed positions are provided on the inner wall of the first housing 221, and these positions correspond to different preset elastic coefficients. By selectively connecting one end of the rolling spring 222 to different fixed positions, the spring elastic coefficient can be adjusted. This design allows the liquid pump to adapt to different pressure and flow requirements by changing the elastic coefficient of the spring under different working conditions, thereby optimizing the working performance of the pump. For example, when the liquid pump needs to provide a large flow, the rolling spring 222 can be connected to a fixed position with a lower elastic coefficient, so that the expansion and contraction action of the spring will be easier, thereby reducing the pressure inside the pump and increasing the flow. On the contrary, if a smaller flow is required, the spring can be connected to a fixed position with a higher elastic coefficient, making the expansion and contraction action of the spring more difficult, thereby increasing the pressure inside the pump and reducing the flow. In this way, the liquid pump can flexibly adjust the output according to actual needs to meet the use requirements under different working conditions. In addition, this adjustment mechanism can also be used for pump maintenance and troubleshooting. When the pump has performance degradation or failure, by adjusting the elastic coefficient of the rolling spring 222, the working state of the pump can be temporarily changed to maintain its basic operation until a thorough repair is carried out. This design not only improves the adaptability and reliability of the liquid pump, but also provides users with more flexible and efficient maintenance methods. In practical applications, the adjustment process of this regulating device can be automated. Through the control unit installed on the pump, the appropriate fixed position can be automatically selected to adjust the elastic coefficient of the rolling spring 222 according to the flow and pressure data detected by the sensor. In this way, the liquid pump can automatically adjust its output according to the actual working conditions, realize intelligent control, and further improve the working efficiency and stability of the pump. In summary, the liquid pump regulating device provided by the present invention, by introducing a rotation detection structure and an adjustment mechanism, not only realizes real-time monitoring and intelligent control of the pump operating status, but also provides flexible adjustment means to adapt to different working conditions and requirements.

[0040] In one embodiment, it also includes a limiting structure 6, which is a semi-arc cylinder. Several limiting structures 6 are spaced apart and arranged on the first shell 221 around the edge of the slot 223. The inner wall of the limiting structure 6 is arranged close to the outer wall of the sleeve 214. One end of the rolling spring 222 passes through the intervals between several limiting structures 6 inside the first shell 221 and is connected to the through hole of the sleeve 214. The limiting structure 6 is used to limit the displacement of the rolling spring 222 during the extension and retraction process.

[0041] In this embodiment, these limiting structures 6 are designed as semi-arc cylinders and are evenly distributed on the first housing 221 around the edge of the slot 223. The inner wall of each limiting structure 6 is closely attached to the outer wall of the sleeve 214, forming a stable support system. This design not only ensures the stability of the sleeve 214 during rotation, but also prevents the deviation or shaking caused by external force. One end of the rolling spring 222 passes through the intervals between the plurality of limiting structures 6 inside the first housing 221 and is connected to the through hole of the sleeve 214. When the rolling spring 222 performs a telescopic action, the limiting structure 6 can provide a clear guide for it to ensure that it always moves along a predetermined trajectory. In addition, the existence of the limiting structure 6 also enhances the impact resistance of the entire detection structure. During the operation of the liquid pump, various emergencies may be encountered, such as sudden power failure, mechanical failure, etc. These emergencies may cause the components inside the liquid pump to be impacted or vibrated. However, due to the existence of the limiting structure 6, the rolling spring 222 and other key components can be effectively supported and protected when impacted, thereby avoiding damage or failure caused by impact.

[0042] refer to Figure 7 The present application provides a method for adjusting a liquid pump, the method comprising: S1: obtaining a liquid flow demand in a liquid pump, and starting a regulating device to adjust the expansion and contraction amount of a rolling spring according to the liquid flow demand, wherein if the liquid flow demand increases, one end of the rolling spring is controlled to extend into a slot closest to the rolling spring, and if the liquid flow demand decreases, one end of the rolling spring is controlled to extend into a slot farthest from the rolling spring; In step S1, the liquid flow demand in the liquid pump is obtained. The liquid flow demand refers to the liquid delivery volume required under the current working conditions. This demand may be affected by many factors, including but not limited to the requirements of the production process, the working state of the equipment, and the changes in the external environment. According to this flow demand, the output of the liquid pump can be accurately controlled to meet the specific requirements of production or application. The liquid flow is monitored in real time by a sensor, and this data is compared with the preset flow demand value. If the actual flow is lower than the demand value, the flow increase adjustment process is entered; on the contrary, if the actual flow is higher than the demand value, the flow reduction adjustment mechanism is started. In the case of increased flow, after receiving the instruction, the regulating device will drive the relevant mechanical structure to gradually increase the expansion and contraction of the rolling spring. In this process, the elongation of the rolling spring is calculated and controlled to ensure that one end of the rolling spring can accurately extend into the nearest card slot adjacent to the rolling spring. As the rolling spring elongates, the pump body parts connected to it will undergo corresponding displacement or deformation, thereby increasing the channel area for liquid circulation and improving the liquid delivery capacity to meet the increased flow demand. On the contrary, in the case of reduced flow, the regulating device will perform the opposite operation, reducing the expansion and contraction of the rolling spring, and controlling one end of the rolling spring to extend into the slot farthest from the rolling spring. This adjustment reduces the displacement or deformation of the pump body components, reduces the channel area for liquid circulation, and thus reduces the liquid delivery speed, achieving a reduction in flow. It is worth noting that increasing or decreasing the expansion and contraction of the rolling spring is based on placing the rolling spring in different slots, and this adjustment process can be performed by automatically pushing or pulling the rolling spring into or out of the corresponding slot through a manipulator or other control device.

[0043] During the entire flow regulation process, in addition to the expansion and contraction adjustment of the rolling spring, it is also equipped with an intelligent control system that can comprehensively consider multiple factors, such as liquid S2: Acquire a Hall sensor signal and a magnetic field signal in the detection structure, and acquire a rotation state value of the rotor according to changes in the Hall sensor signal and the magnetic field signal; In step S2, the monitoring mechanism of the Hall sensor and the magnetic field signal is first introduced. As a magnetic sensor based on the Hall effect, the Hall sensor can sensitively capture the changes in the magnetic field and convert it into an electrical signal output. In the liquid pump, the Hall sensor is cleverly installed on the detection structure to capture the magnetic field changes generated when the rotor rotates in real time. As the rotor rotates, its built-in permanent magnet or magnetic material will periodically change the distribution of the surrounding magnetic field. This change is captured by the Hall sensor and converted into a corresponding electrical signal. At the same time, other sensors or technical means are also used to obtain more comprehensive magnetic field signals to achieve all-round monitoring of the rotor rotation state. After obtaining the Hall sensor signal and the magnetic field signal, these signals are deeply processed and analyzed. By comparing the preset reference signal or model, the key parameters such as the current rotation speed, acceleration, and position of the rotor can be accurately identified. These parameters not only reflect the basic operating state of the rotor, but also provide important data support for subsequent control and regulation. Furthermore, according to the changes in these parameters, the rotation state value of the rotor is comprehensively evaluated. This state value is a comprehensive indicator that integrates information on the rotor's speed, stability, load capacity, and other aspects. By real-time monitoring and evaluating this state value, possible abnormalities or faults in the rotor can be discovered in time, and corresponding measures can be taken to intervene and repair. During the operation of the liquid pump, the stable rotation of the rotor is the key to ensuring stable liquid delivery. Therefore, by introducing the monitoring mechanism of the Hall sensor and the magnetic field signal, accurate grasp and real-time control of the rotor's rotation state are achieved. This not only improves the operating efficiency and stability of the liquid pump, but also provides strong data support for subsequent maintenance and care.

[0044] S3: Determine whether the rotation state value is greater than a preset value, where the preset value includes a first preset threshold and a second preset threshold; S4: If the rotation state value is greater than a first preset threshold, obtain the deviation of the rotation state value greater than the first preset threshold, and adjust the expansion and contraction amount of the rolling spring based on the deviation; if the rotation state value is greater than a second preset threshold, stop running the adjustment device and send a warning signal.

[0045] In steps S3 and S4, the rotor rotation state value calculated in step S2 is compared with two preset thresholds (a first preset threshold and a second preset threshold). These two thresholds can be set comprehensively according to the design parameters, operating experience and safety specifications of the liquid pump to determine whether the current operating state of the rotor is within the normal range. The first preset threshold is usually set to a relatively low threshold to trigger a slight adjustment mechanism; while the second preset threshold is a higher threshold. Once this value is exceeded, it indicates that the rotor may have a more serious abnormality or failure, and immediate measures need to be taken to intervene. When the judgment result shows that the rotation state value is greater than the first preset threshold, the first part of the processing flow of step S4 is entered. At this stage, the deviation of the rotation state value exceeding the first preset threshold is first calculated, that is, the difference between the actual rotation state value and the first preset threshold. This deviation reflects the degree of deviation between the current operating state of the rotor and the ideal state, and is an important basis for the formulation of subsequent adjustment strategies. Subsequently, the expansion and contraction amount of the rolling spring is adjusted according to this deviation. Specifically, the elongation or shortening of the rolling spring is fine-tuned by the control mechanism to change the displacement or deformation of the pump body components, thereby adjusting the liquid delivery capacity and gradually returning the rotation state of the rotor to the normal range. This fine-tuning mechanism helps to correct minor abnormalities of the rotor in a timely manner without affecting the overall operating efficiency. If the rotation state value is greater than the second preset threshold, it indicates that the rotor may have a more serious fault or abnormality. At this time, it is necessary to stop the operation of the adjustment device immediately to prevent the fault from further expanding or causing more serious consequences. At the same time, the system will issue a warning signal to remind the operator to pay attention and take corresponding emergency measures. The warning signal can be presented in a variety of ways such as sound and light alarms and display prompts to ensure that the operator can receive and respond in time. Through the implementation of the above steps, the system can not only realize the precise regulation of the liquid flow in the liquid pump, but also monitor the rotation state of the rotor in real time, and take timely measures to intervene and repair when abnormalities are found. This greatly improves the operating efficiency and stability of the liquid pump, and provides a strong guarantee for the smooth progress of production or application.

[0046] In another embodiment, a remote monitoring and fault diagnosis system is integrated. The system is connected to the built-in controller of the liquid pump via a wireless network, and can receive and process various operating data from the liquid pump in real time, including flow, pressure, temperature, and the rotation state of the rotor, etc. These data are transmitted to the cloud server for big data analysis, and the liquid delivery efficiency and the operating state of the pump body are deeply evaluated and predicted through the preset algorithm model. On the remote monitoring interface, the operator can intuitively view the real-time data, historical operation records and statistical analysis reports of the liquid pump. Through the graphical interface, the operator can easily identify the operating trend of the liquid pump, discover potential problems in time and take corresponding preventive measures. In addition, the system also has an intelligent early warning function. When any abnormal data or trend is detected, it will immediately notify the relevant personnel through SMS, email or APP push to ensure that the problem can be handled in time.

[0047] In one embodiment, the step of obtaining a Hall sensor signal and a magnetic field signal in the detection structure, and obtaining a rotation state value of the rotor according to changes in the Hall sensor signal and the magnetic field signal, comprises: Respectively obtaining time characteristics corresponding to the Hall sensor signal and the magnetic field signal, and performing time alignment on the time characteristics of the two signals; Acquire the maximum and minimum values ​​based on the peak and valley values ​​of the Hall sensor signal, acquire the key points of the rotor position based on the maximum and minimum values ​​of the Hall sensor signal, and acquire the dynamic characteristics of the rotor motion based on the rate of change and intensity of the magnetic field signal; Establishing a mapping relationship between the key points of the rotor position and the dynamic characteristics, and obtaining the actual observation point of the rotor at each time point in the total time characteristics after time alignment of the mapping relationship; The expected observation point of the rotor at each time point is obtained based on the state transfer model prediction, and the expected position is calculated with the actual observation point to obtain the rotation state value of the rotor.

[0048] In this embodiment, based on the fine processing of the Hall sensor signal and the magnetic field signal, the process of obtaining the rotor rotation state value is further refined. First, the time characteristics of the Hall sensor signal and the magnetic field signal are extracted respectively, and the time axes of the two signals are accurately aligned, eliminating the errors that may be caused by time dislocation, and laying a solid foundation for subsequent data processing. The peak and valley values ​​of the signal are identified and extracted by utilizing the periodic change characteristics of the Hall sensor signal. These extreme points correspond to the key moments of the rotor position. At the same time, by analyzing the change rate and intensity of the magnetic field signal, the dynamic characteristics of the rotor during the movement are obtained, which reflect the changes in key parameters such as rotor speed and acceleration. After obtaining the key points and dynamic characteristics of the rotor position, a mapping relationship between them is established. This mapping relationship closely links the key points of the rotor position with its corresponding dynamic characteristics, so that the actual observation point of the rotor at each time point can be accurately found in the total time characteristics after time alignment. Finally, a state transition model is introduced to predict the expected observation point of the rotor at each time point. The state transition model is a prediction tool based on historical data and system characteristics, which can predict the future behavior of the system based on the current system state and input conditions. By comparing and calculating the expected position with the actual observation point, the rotation state value of the rotor is obtained, which reflects the current operating condition of the rotor.

[0049] In one embodiment, the step of calculating the expected position and the actual observation point to obtain the rotation state value of the rotor includes: Calculating the distance information between the expected observation point and the actual observation point of the rotor at each time point to obtain the distance deviation; Acquire the distribution characteristics of the distance deviation, and set the deviation threshold according to the distribution characteristics; The deviation amounts at all time points in the total time feature are traversed, the deviation rate between each time point and the deviation threshold is calculated, and the rotation state value of the rotor is obtained according to the deviation rate.

[0050] In this embodiment, by calculating the distance information between the expected observation point and the actual observation point of the rotor at each time point, a sequence of distance deviations is obtained, which reflects the degree of deviation between the rotor and its expected position at different time points. In order to more accurately evaluate the rotation state of the rotor, the distribution characteristics of the distance deviation are further analyzed. Through statistical analysis, the distribution law of the deviation can be found, such as whether there is a concentrated trend, whether there are abnormal fluctuations, etc. Based on these distribution characteristics, a reasonable deviation threshold can be set to determine whether the rotation state of the rotor is within the normal range. After setting the deviation threshold, the deviations of all time points in the total time feature are traversed, and the deviation rate at each time point is calculated, that is, the ratio of the deviation at the time point to the deviation threshold. This deviation rate provides an indicator for quantifying the degree of deviation of the rotor rotation state. By comparing the deviation rates at different time points, the changing trend of the rotor rotation state can be clearly seen. The rotation state value of the rotor is calculated based on the deviation rate, which not only reflects the degree of deviation of the current position of the rotor, but also includes the dynamic characteristics of the rotor during the motion process. By monitoring this state value, possible abnormalities or faults of the rotor can be discovered in time, and corresponding measures can be taken to adjust or repair it. In another embodiment, the rotation state value can be compared with a preset threshold value to determine whether the rotor is in a normal working state. If the rotation state value exceeds the preset threshold range, the system can automatically trigger an alarm mechanism to remind the operator to pay attention and take corresponding measures. At the same time, the rotation state value can also be compared and analyzed with historical data to discover potential problems or trend changes during the operation of the rotor, providing data support for subsequent maintenance and optimization.
