Description

Technical Field

[0001] This invention relates to the field of material pumping technology, and specifically to a self-adjusting and compensating dual-output single-cylinder pump. Background Technology

[0002] Single-cylinder pumps are widely used in various industries such as agriculture, textiles, and chemicals. The piston in a single-cylinder pump reciprocates within the cylinder, changing the working volume of the pump chamber to draw in and discharge liquid. However, because the single-cylinder pump uses a single piston moving periodically within the cylinder to draw in and discharge liquid, its discharge flow rate is also periodic. In the textile industry, where different colors and volumes of dyes are needed for color mixing, the traditional method is to pump one dye into a container with a specific volume, then add another dye into the same container, mixing the two dyes to achieve color mixing. Clearly, this method is inefficient and costly.

[0003] Existing solutions improve efficiency by increasing the pumping continuity of a single-cylinder pump. Patent application number 201320489059.2 discloses a single-cylinder double-acting slurry pump. The piston divides the pump body's internal bore into two working chambers: a front working chamber and a rear working chamber. The front working chamber is connected to a front feed check valve and a front discharge check valve, while the rear working chamber is connected to a rear feed check valve and a rear discharge check valve. The piston rod passes through one end of the pump body and is slidably sealed to that end. Although the single-cylinder double-acting slurry pump can achieve continuous slurry delivery, this structure requires high sealing and cannot simultaneously deliver two liquids. Patent application number 200680... Patent 008730.X discloses a variable-speed dual-liquid metering and mixing device. This device fills the main agent and hardener into a pressure pump for the main agent and a pressure pump for the hardener from a material supply source. The pressure pump for the main agent and the pressure pump for the hardener are equipped with drive motors that can control the speed of the pumps. Controlling the speed of the motors drives each pressure pump to expel the main agent and hardener in a specified ratio, and then mixes them through a mixer. Although this device can output two liquids, it actually requires two pumps and is not energy-efficient. Patent application number 201220066304.4 discloses a pneumatic diaphragm pump, including two diaphragm chambers and an air valve. It boasts high roundness and flexible, convenient installation. However, this pump discharges liquid by squeezing the diaphragm chambers with gas. While it can be adjusted to simultaneously transport two media, the liquid ratio cannot be adjusted. Patent application number CN202322223869.X discloses a mounting bracket for a pneumatic diaphragm pump, suitable for various specifications of diaphragm pumps. However, this structure adjusts the installation position by rotating bolts, resulting in low efficiency and lacking automatic adjustment of the output material; it merely serves as a support for the installation. Therefore, a single-cylinder pump device is needed that can achieve continuous delivery and output two adjustable proportions of liquid, while also requiring a stable support structure. Summary of the Invention

[0004] Therefore, the technical problem to be solved by the present invention is to overcome the defects of the prior art that a single cylinder cannot output two kinds of liquids and the output liquid ratio is not adjustable, thereby providing a self-adjusting and compensating dual-output single-cylinder pump.

[0005] The above technical objectives of the present invention are achieved through the following technical solutions:

[0006] A self-adjusting and compensated dual-output single-cylinder pump includes a first container, a second container, a power component, a main inlet pipe, a secondary inlet pipe, a main control component, a secondary adjustment component, a main outlet pipe, and a secondary outlet pipe. The main control component and the secondary adjustment component are connected by a linkage assembly. The first container, the main inlet pipe, the power component, the main control component, and the main outlet pipe are connected sequentially, as are the second container, the secondary inlet pipe, the secondary adjustment component, and the secondary outlet pipe. The power component includes a piston chamber, a transmission component, and a drive mechanism. The motor, the transmission component includes an eccentric disk, a transmission connecting rod and a piston head, the piston head is slidably disposed in the piston chamber, the bottom of the piston head is hinged to one end of the transmission connecting rod, the other end of the transmission connecting rod is rotatably mounted on the eccentric disk, the eccentric disk is driven by a drive motor, the main circuit control component includes a drain hose and a receiving frame, the two ends of the drain hose are respectively connected to the power component and the main circuit drain pipe and are mounted on the receiving frame, the auxiliary circuit adjustment component includes two diaphragm structures arranged in parallel and an air chamber connected in series with the diaphragm structures.

[0007] By adopting the above technical solution, a linkage component is set up to achieve linkage between the main circuit and the auxiliary circuit. Under the influence of liquid gravity, one end of the linkage rod moves downward, thereby driving the other end of the linkage rod to move upward. This causes the buffer to squeeze the two diaphragm cavities, discharging the liquid in the diaphragm cavities into a sealed, one-way flowing air chamber. The air chamber generates positive pressure due to the liquid entering. When the one-way valve of the auxiliary circuit pipe is closed, the liquid in the air chamber can be discharged. The diaphragm cavity generates negative pressure due to the liquid being squeezed into the air chamber. Therefore, using the principle of atmospheric pressure, different liquids in the second container are forced into the diaphragm cavity. After the liquid enters the diaphragm cavity, it expands due to the inflow, causing the buffer to move downward, thereby squeezing the drain hose upward. Therefore, when the power component moves to draw liquid again, the liquid in the drain hose can expand again and press down the linkage rod, thus continuing the above process. This cycle can achieve the purpose of outputting two different liquids with a single power component.

[0008] Furthermore, the drain hose is provided with connectors at both ends, which are respectively connected to the power unit and the main drain pipe. The connector is a sealing ring. The receiving frame is sleeved on the connector, and the connector is provided with a snap-fit ​​groove that cooperates with the receiving frame.

[0009] By adopting the above technical solution, a connector is set to connect the drain hose to the power component and the main drain pipe. The drain hose can achieve linkage with the liquid transportation of the secondary road without affecting the main road transportation. The connector also serves to support the drain hose and cooperates with the receiving frame.

[0010] Furthermore, diaphragm structures are arranged side-by-side on the rear side of the drainage hose. Each diaphragm structure includes a diaphragm cavity and a diaphragm frame. The diaphragm cavity is slidably mounted on the diaphragm frame. The bottom of the diaphragm cavity is ellipsoidal. An inlet and an outlet are arranged side-by-side above the top of the diaphragm cavity. The inlet is connected to a secondary inlet pipe via a secondary inlet branch pipe. A secondary inlet valve is provided on the secondary inlet branch pipe. The outlet is connected to an air chamber via a secondary outlet branch pipe. A secondary control valve is provided on the secondary outlet branch pipe near the air chamber.

[0011] By adopting the above technical solution, the secondary circuit uses two diaphragm cavities connected in series and working in conjunction. When one of the diaphragm cavities fails or the pipeline of one diaphragm cavity fails, the secondary circuit inlet valve of the corresponding failed diaphragm cavity can be closed, and only the other diaphragm cavity can be used to work, without affecting the operation of the material conveying component.

[0012] Furthermore, the two ends of the diaphragm cavity are extended with sliding frames that are connected to the diaphragm frame body. The diaphragm frame body is provided with sliding grooves for the sliding frames to slide vertically. The diaphragm frame body is also provided with a lifting motor to control the lifting of the sliding frames. The lifting motor includes two side lifting and a common lifting. The common lifting is located between the two diaphragm cavities and drives the two diaphragm cavities to lift.

[0013] By adopting the above technical solution, the liquid discharged from the diaphragm cavity is also affected by the depth of compression. The vertical height of the diaphragm cavity can be controlled by adjusting the position of the sliding frame and the diaphragm frame, thereby controlling the liquid output. Two side lifting and a shared lifting mechanism are set to adjust the position of the two diaphragm cavities simultaneously to ensure their synchronization.

[0014] Furthermore, the air chamber is located at the end of the diaphragm cavity away from the secondary inlet pipe. The air chamber is connected to two secondary outlet pipes via a secondary outlet main pipe near the top. A secondary drain pipe is connected to the air chamber near the bottom. A pressurization device is also provided on one side of the top of the air chamber.

[0015] By adopting the above technical solution, a pressurizing device is installed at the top of the air chamber, which can adjust the pressure inside the air chamber. When a higher output pressure is required, the pressurizing device can be controlled to increase the pressure inside the air chamber, but the pressure inside the air chamber must always be kept lower than the discharge pressure of the diaphragm cavity, so that a higher output pressure can be achieved.

[0016] Furthermore, the linkage assembly includes a linkage bracket, a main path connecting bracket, a secondary path connecting bracket, and a linkage rod. The main path connecting bracket and the secondary path connecting bracket are located at both ends of the linkage rod. The linkage rod is rotatably mounted on the linkage bracket. The secondary path connecting bracket includes a buffer and a support bracket. The support bracket is U-shaped with an upward opening and a vertical buffer is fixed at the center of its bottom. The bottom of the buffer is fixed to one end of the linkage rod. The support bracket is arranged along the length of the drainage hose. The top two ends of the support bracket are provided with trays that cooperate with the diaphragm cavity. The trays are arc-shaped and fixed below the diaphragm cavity.

[0017] By adopting the above technical solution, the linkage component amplifies the changes in the main circuit and affects the secondary circuit, realizing the changes in positive and negative pressure in the secondary circuit, thereby controlling the secondary circuit to pump and transport liquid. The buffer can buffer the instantaneous changes in liquid pressure, reduce the impact on the diaphragm cavity, and extend the service life of the equipment. At the same time, the buffer can further smooth the output flow and improve the stability of liquid output.

[0018] Furthermore, the linkage rod and the linkage bracket are slidably arranged relative to each other. The linkage rod has multiple adjustment holes. The linkage bracket is provided with adjustment bolts corresponding to the adjustment holes on its upper part. The linkage bracket includes a rotating bracket, a support bracket, and a sliding base. The rotating bracket is U-shaped with its opening facing downward and is configured to cooperate with the linkage rod. The support bracket is located at both ends of the bottom of the rotating bracket and is slidably arranged on the sliding base. The sliding base is provided with a sliding groove corresponding to the support bracket.

[0019] By adopting the above technical solution, the linkage rod and linkage bracket form an adjustable lever structure. When the control fulcrum is close to the drain hose, the short-range motion of the drain hose can be converted into the long-range motion of the buffer and diaphragm cavity, thereby squeezing the diaphragm cavity to a greater extent and discharging more liquid from the diaphragm cavity.

[0020] Furthermore, the linkage bracket extends into an abutment bracket near the secondary road connecting bracket. The abutment bracket is configured to cooperate with the bottom of the linkage rod and has an abutment plate extending from the bottom. The abutment bracket is also slidably mounted on the sliding base.

[0021] By adopting the above technical solution, the abutment frame is used to abut against the lower part of the linkage rod near the auxiliary road connection frame, so as to prevent the end from tilting too much under normal conditions and pulling on the diaphragm cavity, causing damage to the diaphragm cavity.

[0022] Furthermore, it also includes a control console, which is connected to the lifting motor, the auxiliary control valve, the auxiliary liquid inlet valve and the pressurization device for signal control. The main liquid inlet pipe, the auxiliary liquid inlet pipe, the main liquid outlet pipe and the auxiliary liquid outlet pipe are all equipped with flow detection valves, and the control console is also connected to the flow detection valves for communication.

[0023] By adopting the above technical solution, the control console can communicate with multiple flow control valves, detect corresponding flow changes, facilitate subsequent control adjustments, and realize real-time flow compensation operations.

[0024] Furthermore, both ends of the power component are equipped with main-path check valves, and secondary-path check valves are installed between the secondary-path inlet pipe and the diaphragm structure, and between the diaphragm structure and the air chamber. Secondary-path inlet branch pipe and secondary-path outlet branch pipe are also equipped with secondary-path branch pipe check valves.

[0025] By adopting the above technical solution, multiple one-way valves are set up to avoid liquid backflow affecting the output volume ratio, and to prevent the pressure change caused by liquid backflow from not significantly affecting the liquid suction effect.

[0026] In summary, the technical solution of the present invention has the following advantages:

[0027] 1. The self-adjusting and compensated dual-output single-cylinder pump provided by the present invention utilizes the power component to discharge liquid and transfer the original kinetic energy to the linkage component to squeeze the diaphragm structure. The linkage component is set to amplify the changes in the main circuit and affect the secondary circuit, realizing the change of positive and negative pressure in the secondary circuit, thereby controlling the secondary circuit to pump and transport liquid. The diaphragm cavity draws in and discharges liquid through changes in concavity and convexity, realizing the output of two different liquids in the main circuit and the secondary circuit. The liquid output ratio of the main circuit and the secondary circuit can be adjusted as needed, and the output process is detected and adjusted and compensated in real time.

[0028] 2. The self-adjusting and compensated dual-output single-cylinder pump provided by the present invention uses two diaphragm chambers connected in series and working in linkage in the auxiliary circuit. When one of the diaphragm chambers fails or the pipeline of one diaphragm chamber fails, the auxiliary circuit inlet valve of the corresponding failed diaphragm chamber can be closed, and only the other diaphragm chamber is used for operation. This does not affect the operation of the material conveying component and increases the working continuity and reliability of the diaphragm chamber.

[0029] 3. The self-adjusting and compensated dual-output single-cylinder pump provided by the present invention controls the vertical height of the diaphragm cavity by adjusting the position of the sliding frame and the diaphragm frame body, thereby controlling the liquid output and achieving the adjustability of the device.

[0038] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only for explaining the present invention and are not intended to limit the present invention.

[0039] A self-adjusting and compensated dual-output single-cylinder pump, such as Figure 1 As shown, the system includes a first container 1, a second container 2, a power unit 3, a main inlet pipe 4, a secondary inlet pipe 5, a main control unit 6, a secondary adjustment unit 7, a main drain pipe 8, and a secondary drain pipe 9. The main control unit 6 and the secondary adjustment unit 7 are connected by a linkage assembly 10. The first container 1, the main inlet pipe 4, the power unit 3, the main control unit 6, and the main drain pipe 8 are connected in sequence, as are the second container 2, the secondary inlet pipe 5, the secondary adjustment unit 7, and the secondary drain pipe 9. The linkage component 10 is set up to realize the linkage between the main circuit and the auxiliary circuit. Under the influence of liquid gravity, one end of the linkage rod 104 moves downward, thereby driving the other end of the linkage rod 104 to move upward. This causes the buffer 1031 to squeeze the two diaphragm chambers 711, discharging the liquid in the diaphragm chambers 711 into the sealed one-way flow air chamber 72. Positive pressure is generated in the air chamber 72 due to the liquid entering. When the one-way valve 15 of the auxiliary circuit pipe is closed, the liquid in the air chamber 72 can be discharged. The diaphragm chambers 711 are squeezed by the liquid. A negative pressure is generated in the air chamber 72. Therefore, the different liquids in the second container 2 are forced into the diaphragm cavity 711 by using the principle of atmospheric pressure. After the liquid enters the diaphragm cavity 711, it expands due to the liquid inlet, which drives the buffer 1031 to move downward, thereby squeezing the drain hose 61 to move upward. Therefore, when the power component 3 moves to draw liquid again, the liquid in the drain hose 61 can expand again and press down the linkage rod, thereby continuing to execute the above process. In this cycle, the purpose of outputting two different liquids by a single power component 3 can be achieved.

[0040] It also includes a control console 11, and flow detection valves 12 are installed on the main inlet pipe 4, the secondary inlet pipe 5, the main outlet pipe 8, and the secondary outlet pipe 9. The control console 11 is communicatively connected to the flow detection valves 12. The control console 11 is communicatively connected to multiple flow control valves, which can detect the corresponding flow changes, facilitating subsequent control adjustments and real-time flow compensation operations.

[0041] like Figure 1 and Figure 2As shown, the power component 3 includes a piston chamber 31, a transmission component 32, and a drive motor 33. The transmission component 32 includes an eccentric disk 321, a transmission connecting rod 322, and a piston head 323. The piston head 323 is slidably disposed within the piston chamber 31. The bottom of the piston head 323 is hinged to the upper end of the transmission connecting rod 322. The lower end of the transmission connecting rod 322 is eccentrically mounted on the eccentric disk 321. The eccentric disk 321 is driven by the drive motor 33. The rotation of the drive motor 33 causes the eccentric disk 321 to rotate. Because the transmission connecting rod 322 is eccentrically mounted to the eccentric disk 321, the swinging motion of the transmission connecting rod 322 causes the piston head 323 at its top to reciprocate within the piston chamber 31, thereby achieving the extraction of liquid from the first container 1. A main-path one-way valve 13 is provided at both ends of the power component 3 to prevent liquid backflow from affecting the output volume ratio.

[0042] like Figure 1 , Figure 2 and Figure 4 As shown, the drain hose 61 has connectors 611 at both ends, which are connected to the power unit 3 and the main drain pipe 8 respectively. The drain hose 61 enables the linkage of liquid transportation on the secondary route without affecting the main route transportation. The connector 611 is a sealing ring, and the upper end of the receiving frame 62 is sleeved on the connector 611. The side wall of the connector 611 has a snap-fit ​​groove 612 that mates with the receiving frame 62. The connector 611 connects the drain hose 61 to the power unit 3 and the main drain pipe 8, and the connector 611 serves to support the drain hose 61 and mates with the receiving frame 62.

[0043] like Figure 1 , Figure 3 and Figure 4 As shown, diaphragm structures 71 are arranged side-by-side on the rear side of the drain hose 61. Each diaphragm structure 71 includes a diaphragm cavity 711 and a diaphragm frame 712. The diaphragm cavity 711 is slidably mounted on the diaphragm frame 712. The secondary circuit uses two diaphragm cavities 711 connected in series and operating in conjunction. When one diaphragm cavity 711 fails or the pipeline of one diaphragm cavity 711 fails, the secondary circuit inlet valve 71112 of the corresponding failed diaphragm cavity 711 can be closed, and only the other diaphragm cavity can be used for operation, without affecting the operation of the material conveying component.

[0044] The bottom of the diaphragm cavity 711 is ellipsoidal. An inlet 7111 and an outlet 7112 are arranged side-by-side on the top of the diaphragm cavity 711. The inlet 7111 is connected to the secondary inlet pipe 5 via a secondary inlet branch pipe 71111. A secondary inlet valve 71112 is installed on the secondary inlet branch pipe 71111. The outlet 7112 is connected to the air chamber 72 via a secondary outlet branch pipe 71121. A secondary control valve 7113 is installed near the air chamber 72. Secondary check valves 14 are installed between the secondary inlet pipe 5 and the diaphragm structure 71, and between the diaphragm structure 71 and the air chamber 72. Secondary inlet branch pipes 71111 and 71121 are also equipped with secondary branch check valves 15. The control console 11 is connected to the secondary control valve 7113 and the secondary inlet valve 71112 via signal control. The multiple check valves prevent liquid backflow from affecting the output volume ratio and also prevent the pressure changes caused by liquid backflow from being insignificant and affecting the liquid suction effect.

[0045] Each diaphragm cavity 711 has sliding frames 7114 extending from both its left and right ends, connecting to the diaphragm frame 712. The diaphragm frame 712 has sliding grooves 7121 for vertical sliding of the sliding frames 7114. A lifting motor 7122 is also installed on the diaphragm frame 712 to control the lifting of the sliding frames 7114. The control console 11 is connected to the lifting motor 7122 via signal control. The lifting motor 7122 includes two side lifting mechanisms 71221 and a common lifting mechanism 71222. The common lifting mechanism 71222 is located between the two diaphragm cavities 711 and drives the lifting of both diaphragm cavities 711. The liquid discharged from the diaphragm cavity 711 is also affected by the depth of compression. The vertical height of the diaphragm cavity 711 can be controlled by adjusting the position of the sliding frame 7114 and the diaphragm frame 712, thereby controlling the liquid output. Two side lifts 71221 and a common lift 71222 are set to adjust the position of the two diaphragm cavities 711 at the same time to ensure their synchronization.

[0046] like Figure 1 and Figure 4 As shown, the air chamber 72 is located at the end of the diaphragm cavity 711 away from the secondary inlet pipe 5. The air chamber 72 is connected to two secondary outlet pipes 71121 via a secondary outlet main pipe 721 near the top. A secondary drain pipe 9 is connected to the air chamber 72 near the bottom. A pressurizing device 722 is also installed on one side of the top of the air chamber 72. The control console 11 is connected to the pressurizing device 722 via signal control. The pressurizing device 722 installed on the upper part of the air chamber 72 can adjust the pressure inside the air chamber 72. When a higher output pressure is required, the pressurizing device 722 can be controlled to increase the pressure inside the air chamber 72, but the pressure inside the air chamber 72 must always be kept lower than the discharge pressure of the diaphragm cavity 711, thus achieving a higher output pressure.

[0047] like Figure 1 , Figure 3 and Figure 4 As shown, the linkage assembly 10 includes a linkage bracket 101, a main line connecting bracket 102, a secondary line connecting bracket 103, and a linkage rod 104. The main line connecting bracket 102 and the secondary line connecting bracket 103 are positioned above the front and rear ends of the linkage rod 104. The linkage rod 104 is rotatably mounted on the linkage bracket 101. The secondary line connecting bracket 103 includes a buffer 1031 and a support bracket 1032. The support bracket 1032 is U-shaped with an upward opening and a vertical buffer 1031 is fixed at the center of its bottom. The bottom of the buffer 1031 is fixed to the rear end of the linkage rod 104. The support bracket 1032 is arranged along the length of the drainage hose 61. The top two ends of the support bracket 1032 are provided with trays 10321 that cooperate with the diaphragm cavity 711. The trays 10321 are arc-shaped and fixed below the diaphragm cavity 711. The linkage component 10 amplifies the changes in the main circuit and affects the secondary circuit, realizing the changes in positive and negative pressure in the secondary circuit, thereby controlling the secondary circuit to pump and transport liquid. The buffer 1031 can buffer the instantaneous changes in liquid pressure, reduce the impact on the diaphragm cavity, and extend the service life of the equipment. At the same time, the buffer 1031 can further smooth the output flow and improve the stability of liquid output.

[0048] The linkage rod 104 and the linkage bracket 101 are slidably arranged relative to each other. Multiple adjustment holes 1041 are provided on the linkage rod 104. An adjustment bolt 1015 is provided on the upper part of the linkage bracket 101 corresponding to the adjustment holes 1041. The linkage rod 104 and the linkage bracket 101 form an adjustable lever structure. When the control fulcrum is close to the drain hose 61, that is, when the control adjustment bolt 1015 passes through the adjustment hole 1041 near the drain hose 61, the short-range movement of the drain hose 61 can be converted into the long-range movement of the buffer 1031 and the diaphragm cavity 711, thereby squeezing the diaphragm cavity 711 to a greater extent and discharging more liquid from the diaphragm cavity.

[0049] The linkage bracket 101 includes a rotating bracket 1011, a support bracket 1012, and a sliding base 1013. The rotating bracket 1011 is U-shaped with its opening facing downwards and is configured to cooperate with the linkage rod 104. The support bracket 1012 is located at the left and right ends of the bottom of the rotating bracket 1011 and is slidably mounted on the sliding base 1013. The sliding base 1013 is provided with a sliding groove 10131 corresponding to the support bracket 1012. The fulcrum position of the lever is determined by the sliding of the support bracket 1012 within the sliding groove 10131.

[0050] Near the auxiliary connecting bracket 103, the linkage bracket 101 extends a contact bracket 1014. The contact bracket 1014 is fitted to the bottom of the linkage rod 104, and a contact plate 10141 extends from the bottom. The contact bracket 1014 is also slidably mounted on the sliding base 1013. The contact bracket 1014 is used to abut against the bottom of the linkage rod 104 near the auxiliary connecting bracket 103 to prevent this end from tilting too much under normal conditions and pulling on the diaphragm cavity 711, causing damage to the diaphragm cavity 711.

[0051] like Figure 1 and Figure 5 The specified parameters are: working pressure 4MPa, outlet diameter 80mm, and discharge capacity 0.05m³. 3 For a power component 3 that performs 60 reciprocating strokes per minute, the volume of liquid discharged during each stroke is 0.8L, and the pressure of the discharged liquid is F = PS = 4MPa * Π * (80mm / 2). 2 =20000N, selecting a diaphragm cavity 711 with a length of a mm, a maximum depth of b mm, and a width of c (the liquid discharged from the diaphragm cavity 711 is the vertical movement part of the buffer 1031, and this part of the diaphragm cavity 711 is calculated as an approximate ellipsoid), then the maximum discharge volume in a single operation is approximately Taking a diaphragm cavity with a length of 200mm, a depth of 100mm, and a width of 200mm as an example, the maximum discharge volume in a single operation is approximately 2L, and the gravity of the maximum discharge volume in a single operation is G = 19.6N. Since the discharge pressure of the main pipeline is greater than the liquid pressure of the secondary pipeline, this method is theoretically feasible.

[0052] Establish a functional relationship between the volume of liquid discharged from the diaphragm cavity 711 and the vertical depth to which the diaphragm cavity is compressed (taking the control fulcrum of the linkage support at the center as an example, the top of the support frame as the coordinate base point, and the distance x from the bottom of the diaphragm cavity 711 to the base point). Then, the volume of liquid discharged from the diaphragm cavity is: (unit: m³) 3 )

[0053]

[0054] When two liquids with a specific volume ratio V2 / V1 need to be discharged (V1 represents the liquid volume output from the main line, and V2 represents the liquid volume output from the auxiliary line), the output volumes of the two liquids are preset in the control console 11. The control console 11 calculates the required height of the diaphragm cavity 711 based on the trained feature model. The control console 11 is connected to the lifting motor 7122 for signal control, controlling the diaphragm cavity 711 to rise or fall, thus reaching the specified height and achieving the output of the two liquids with a specific volume ratio. The flow detection valves 12 installed on the main drain pipe 8 and the auxiliary drain pipe 9 can detect the output liquid volume (V2′, V1′) in real time and transmit the data to the control console 11 every minute. The internal system of the control console 11 calculates and determines the output volume ratio based on the cumulative volume ratio of the output liquids. The position of the diaphragm cavity 711 is automatically adjusted so that... (Error range ±0.2), achieving precise control of the output ratio of the two liquids.

[0055] The working principle and usage of this self-adjusting and compensated dual-output single-cylinder pump are as follows: Set the initial position of the diaphragm cavity 711 in the control panel 11, and then start the power unit 3. The power unit 3 starts to draw liquid from the first container 1, which drives the main discharge hose 61 to expand and press down on one end of the linkage component 10. The linkage component 10 and the auxiliary circuit work together to squeeze the diaphragm cavity 711, drawing liquid from the second container 2 into the two diaphragm cavities 711. After the diaphragm cavity 711 expands due to the liquid inlet, it drives the buffer 1031 to move downward, thereby squeezing the discharge hose 61 to move upward. Therefore, the discharge hose 61 and the diaphragm cavity 711 are always in a state of dynamic balance, and different liquids can be output from the main circuit and the auxiliary circuit at the same time.
