DETAILED DESCRIPTION

Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0028] It should be noted that in this embodiment, the directions or positional relationships indicated by "upper", "lower", "front", "back", etc. are based on the directions or positional relationships shown in the drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as limiting the present application. In addition, "first", "second", "third", and "fourth" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0029] In order to enable those skilled in the art to better understand the present application, the present application is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0030] In the field of industrial fluid pump technology, the pump body is usually responsible for the fluid delivery, while the heating function is achieved by an independent heater or through a heating pipe outside the pump and electromagnetic heating technology. This separate heating method has the following main problems:

[0031] Low thermal efficiency: Since the external heater is separated from the fluid pump, the heat energy transfer efficiency is low, resulting in energy waste;

[0032] Complex installation: Additional pipes and fittings are required to connect the heater to the pump body, increasing the complexity of the system and the installation cost;

[0033] Large footprint: External heaters require additional space, which is particularly inconvenient in industrial environments where space is limited;

[0034] Safety hazards: External heaters may pose safety risks such as overheating and leakage, especially in flammable and explosive environments;

[0035] High maintenance cost: As the number of system components increases, the cost of maintenance and repair also increases;

[0036] Difficulty in controlling fluid temperature: External heaters may have difficulty in achieving precise control of fluid temperature, affecting process stability and product quality.

[0037] Based on the above situation, the present application provides a fluid pump housing, in which the heating element 4 can be built into the pump body to directly perform contact heating on the fluid flowing through the pump body, and at the same time utilize the heat dissipation effect of the pump body to put the heating element 4 on the pump body in a safe heating environment.

[0038] Specifically, please refer to Figure 1 and Figure 2 The fluid pump housing of this embodiment includes a motor base 1 as the main part of the pump body. A motor is arranged in the motor base 1. The motor serves as the power output mechanism of the pump body and is used to provide power for pumping liquid. A pump liquid chamber 21 is arranged at one end of the motor base 1, and a heat dissipation chamber 32 is arranged at the other end. The pump liquid chamber 21 and the heat dissipation chamber 32 are respectively located on the axis of both sides of the motor. A heating element 4 is also arranged on the motor base 1. The heating end 41 of the heating element 4 extends into the pump liquid chamber 21 and is in direct contact with the fluid in the pump liquid chamber 21 for heating. The heat dissipation chamber 32 is used to form a heat dissipation path a, so that the heat dissipation medium in the heat dissipation chamber 32 flows along the outer wall of the motor base 1 from the heat dissipation chamber 32 to the pump liquid chamber 21, thereby realizing heat exchange between the heat dissipation medium and the motor base 1, so as to reduce the ambient temperature of the heating element 4 at the motor base 1.

[0039] It should be noted that the present application builds the heating element 4 into the pump body, which can directly contact and heat the fluid, improve the heat exchange efficiency, reduce energy consumption, and reduce the need for external heaters and connecting pipes, simplifying the system design. At the same time, the design of the built-in heating element 4 saves the space required for installing the external heater, making the pump body more compact and reducing the safety hazards of the external heating equipment. In addition, heating elements 4 of different models and sizes can be selected according to the size adaptability of the pump body to improve the versatility and applicability of the body.

[0040] In summary of the above embodiments, the fluid pump housing of the present application includes a motor base 1, a pump liquid chamber 21 and a heat dissipation chamber 32, a heating element 4 is arranged on the motor base 1, and a heating end 41 of the heating element 4 extends into the pump liquid chamber 21 and contacts with the fluid, thereby improving the heat energy transfer efficiency between the heating element 4 and the fluid, while avoiding the problem of occupying additional space caused by the heating element 4 being located outside the pump body. The heat dissipation path a of the heat dissipation chamber 32 enables the heat dissipation medium to flow along the outer wall of the motor base 1, specifically, the heat dissipation medium flows from the heat dissipation chamber 32 to the pump liquid chamber 21, thereby realizing heat exchange between the heat dissipation medium and the motor base 1, and finally dissipating to the surrounding environment, keeping the motor base 1 within a safe working temperature. In addition, since the heating element 4 is arranged on the motor base 1, when the motor base 1 is within a safe working temperature, the ambient temperature of the heating element 4 itself is also within a safe range, and the temperature range of the motor base 1 can be adjusted by adjusting the flow rate, flow rate, etc. of the heat dissipation medium to adapt to the safe temperature range of the heating element 4.

[0041] There are many options for the heating element 4, such as a heating rod, a heating wire, etc., which will not be described in detail here. All components with heating functions fall within the protection scope of this application. Figure 5 and Figure 6 The harness end of the heating rod is sealed and connected to the motor base 1 through the tapered sealing thread 43, which not only ensures the high efficiency of heat energy transfer, but also strengthens the mechanical stability of the entire structure. At the same time, the sealing pad 42 is used to achieve sealing against the motor base 1, further improving the sealing performance and preventing the fluid from entering the motor base 1 through the heating rod. The heating end 41 of the heating rod extends into the pump liquid chamber 21 and contacts with the fluid for heating.

[0042] The number of heating rods can be multiple and evenly distributed on the side wall of the motor base 1 facing the pump liquid chamber 21. Figure 5 A side wall of the motor base 1 serves as a cavity wall of the pump liquid cavity 21, and the heating rod is arranged on the cavity wall. At the same time, the fluid in the pump liquid cavity 21 contacts the cavity wall, and part of the heat of the cavity wall can also be taken away, thereby heating the fluid and cooling the motor base 1.

[0043] Generally speaking, during the operation of the motor of the pump body, the resistance heat generated when the current passes through the motor coil will generate a certain amount of heat inside the motor base 1, and the heat will be transferred to the motor base 1 by heat conduction. Therefore, the heating element 4 provided on the motor base 1 and the motor itself need to have a certain heat dissipation structure to dissipate the heat, so as to ensure a safe operating environment.

[0044] When the motor is powered on, there will be energy loss due to iron loss and copper loss. The copper coil will lose energy and generate heat due to resistance, and the iron core structure will cause hysteresis and eddy current effect, causing part of the electrical energy to be converted into heat energy for dissipation. This heat needs to be effectively dissipated, otherwise it will affect the performance and life of the motor and the heating element 4.

[0045] The heat dissipation cavity 32 is designed to efficiently remove the heat in the motor cavity 12, so that the motor and the heating element 4 are at a safe operating temperature. Figure 2 and Figure 3 An air guide cover 3 is provided at one end of the motor base 1 away from the pump liquid chamber 21. The air guide cover 3 and the motor base 1 are spaced apart to form a heat dissipation chamber 32. At the same time, an air inlet 33 is opened in the middle of the air guide cover 3. The outer edge of the air guide cover 3 is bent toward the motor base 1 to form an annular portion 31, and the annular portion 31 is sleeved on the outer periphery of the end of the motor base 1.

[0046] Please refer to Figure 2 and Figure 4 A fan blade 15 is provided in the gap between the air guide cover 3 and the motor base 1. The fan blade 15 is connected to the motor shaft core 13 of the motor in the motor base 1. The fan blade 15 is used to drive the heat dissipation medium into the heat dissipation cavity 32 through the air inlet 33, and the flow direction of the heat dissipation medium is changed by the annular portion 31 so that the heat dissipation medium flows along the outer wall of the motor base 1 for heat exchange.

[0047] Please refer to Figure 7 In the heat dissipation path a, the external heat dissipation medium (air) is sucked into the heat dissipation cavity 32 through the forced convection of the fan blades 15, and then the direction of the heat dissipation medium is changed by the annular portion 31, so that the heat dissipation medium can flow along the outer wall of the motor. At the same time, the motor base 1 is made of high thermal conductivity material, and a heat sink or heat dissipation fin 14 in contact with the heat exchange medium is provided on the outer wall of the motor base 1 to increase the heat dissipation area and improve the heat dissipation efficiency. After completing the heat exchange, the heat dissipation medium is finally dissipated to the surrounding environment, keeping the motor base 1 within a safe temperature range.

[0048] It should be pointed out that the above heat dissipation methods include but are not limited to air cooling, and other methods such as liquid cooling can also be used. For example, liquid refrigerant is introduced into the heat dissipation cavity 32, and the heat dissipation cavity 32 can surround the outer periphery of the motor base 1, so as to achieve heat exchange. For another example, heat exchange with the motor base 1 is achieved through the fluid in the pump liquid cavity 21, that is, the heat dissipation cavity 32 can be connected with the pump liquid cavity 21, and the heat dissipation cavity 32 is also distributed on the outer periphery of the motor base 1, so that part of the fluid in the pump liquid cavity 21 can be, for example, in the heat dissipation cavity 32, so as to achieve the purpose of heat dissipation.

[0049] The present application also provides a fluid pump including the above fluid pump housing, wherein the pump chamber 21 of the fluid pump is equipped with a pump head including a pump housing 2, an impeller 22 and a guide vane 23, and these components work together to continuously provide stable hydraulic kinetic energy for the entire system. Figure 2 The pump housing 2 is disposed at the end of the motor base 1 away from the heat dissipation cavity 32. The pump housing 2 is sealed and connected to the motor base 1 to form a pump liquid cavity 21 for fluid flow. The specific connection method between the pump housing 2 and the motor base 1 is not described here, and reference may be made to the prior art. In some embodiments, the fluid outlet 24 of the pump liquid cavity 21 is disposed on a side close to the heating element 4, so that the fluid contacts and heats the heating element 4 when it is about to be discharged from the pump liquid cavity 21, thereby avoiding heat loss of the fluid due to an excessively long pumping path.

[0050] Generally speaking, the impeller 22 is connected to the motor shaft core 13 of the motor, and the guide vane 23 cooperates with the impeller 22 to provide stable, efficient and reliable kinetic energy for the fluid. In order to prevent leakage, the pump liquid chamber 21 adopts a composite sealing structure composed of a mechanical shaft seal and a sealing ring, and has a protection level higher than IP55. The impeller 22 moves in a circular motion in the pump liquid chamber 21 through the blade installation angle under the action of centrifugal force, accelerates and compresses the liquid, and ensures that the pump head achieves excellent performance in key performance indicators such as head and flow.

[0051] When the pump is running, please refer to Figure 7 The fluid is sucked into the pump fluid cavity 21 through the pump fluid inlet 25 under the action of negative pressure. After the fluid enters the pump fluid cavity 21, it is driven to rotate by the impeller 22. The rotation of the impeller 22 generates centrifugal force, which throws the fluid out of the impeller 22 to the guide vane 23 and enters the second-stage impeller 22, the third-stage impeller 22, and the Nth-stage impeller 22, thereby increasing the water pressure. The pressurized fluid is transported to the water outlet pipe through the fluid outlet 24, and finally transported to the place where water is needed through the water outlet pipe. The performance of the pump fluid can be adjusted by adjusting the speed of the impeller 22, changing the diameter of the impeller 22, or using a control system to meet different water needs.

[0052] The fluid pump of the present application also includes a control system, which includes a control panel 5 arranged on the motor base 1, and the control system also serves as the control system of the pump body itself. Figure 2, the control board 5 is arranged in the distribution box 11 on the motor seat 1, and the control board is respectively connected to the motor, the heating element 4 and the temperature sensor by signals. The temperature sensor is built into the pump liquid chamber 21, and the control board 5 has a built-in AI control strategy to adjust the output power of the motor, the heating power of the heating element 4 and maintain the fluid in the pump liquid chamber 21 in a preset temperature range. In other words, the fluid pump of the present application has the characteristics of flexibility and intelligence, and it can flexibly adjust the configuration of the heating rod according to the actual application scenario, including the quantity, layout and structural form. The control system supports a variety of working modes to ensure working stability, such as single point, multi-point or interactive, and also provides a shutdown option, which can be automatically or manually started as needed. The control system monitors temperature changes in real time through a fluid temperature sensor, and the sensor is installed close to the pump liquid chamber 21 to ensure fast and accurate perception of temperature changes. The control board 5 has a built-in AI control strategy, which can intelligently adjust the heating state and maintain the fluid in an ideal temperature range. In addition, the integrated control system has multiple safety guarantees such as overheating, short circuit, and leakage, which will automatically cut off the power to ensure that the equipment can operate stably and safely under various working conditions.

[0053] The motor is built into the motor cavity 12 of the motor base 1. The lead wires at the wiring harness end of the heating element 4 are made of high-temperature resistant material wires, and the lead wires are led out through the motor cavity 12 and connected to the control board 5, or are safely led out through a preset channel in the motor base 1 and connected to the control board 5.

[0054] In general, the fluid pump housing and fluid pump of the present application are divided into four main parts: a pump liquid chamber 21, a motor base 1, a heat dissipation chamber 32 and a heating element 4. The various parts work together to achieve heat transfer and system heat dissipation, ensuring that the heating element 4 operates in a safe temperature zone, and essentially achieving a comprehensive improvement in the thermal safety of the pump body and the entire system of pumping liquid; the heating element 4 is tightly combined with the motor base 1, and contacts and heats the fluid in the pump liquid chamber 21, achieving efficient heating management and optimal utilization of thermal energy for the fluid, while having high sealing and mechanical stability; the heating rod includes a specially designed heating shell, a high-density sealing pad 42 and a power cord made of high-temperature resistant material to ensure rapid generation and conduction of heat energy while enhancing mechanical stability; the heating rod configuration can be adjusted according to actual application scenarios to support a variety of working modes, and the temperature changes can be monitored in real time through the control system and fluid temperature sensor to achieve AI intelligent adjustment.

[0055] It should be noted that, in this specification, relational terms such as first and second are merely used to distinguish one entity from other entities, but do not necessarily require or imply any actual relationship or order between these entities.

[0056] Specific examples are used herein to illustrate the principles and implementation methods of the present application, and the description of the above embodiments is only used to help understand the method and core ideas of the present application. It should be pointed out that for ordinary technicians in this technical field, without departing from the principles of the present application, several improvements and modifications can be made to the present application, and these improvements and modifications also fall within the scope of protection of the claims of the present application.
