[0002] Constant pressure water supply systems are currently widely used in building water supply, industrial water supply and other scenarios. As the core power component of the water supply system, the heat dissipation performance, energy consumption control and operation stability of the variable frequency induction motor directly affect the overall working efficiency of the water supply system.

The constant pressure water pump includes a pump body and a motor, with the motor positioned above the pump body. The pump body has an inlet and an outlet on its side, with a pressure sensor inside the outlet. The motor has an outer sleeve that wraps around its outer surface, forming a sealed cooling chamber between the outer sleeve and the outer surface of the motor. The lower end of the cooling chamber is connected to an inlet pipe, and the outer end of the inlet pipe is connected to a water supply pump, which is located inside the water tank. The upper end of the cooling chamber has an outlet pipe, the other end of which is connected to the water tank.

The water supply pump, pressure sensor, and motor are all connected to the frequency converter. This patent has good heat dissipation performance, and the cooling water is recycled, resulting in high utilization and water conservation, making it very environmentally friendly.

[0004] Regarding the aforementioned technologies, the inventors believe that there is a drawback: they cannot adaptively match the heat dissipation effect according to their own operating speed. Summary of the Invention

[0005] To address the aforementioned technical issues, this application provides an integrated energy-saving variable frequency induction motor for constant pressure water supply.

[0006] This application provides an integrated energy-saving variable frequency induction motor for constant pressure water supply, which adopts the following technical solution: An integrated constant pressure water supply energy-saving variable frequency induction motor includes a drive motor and a water pump. The water pump is located at the output end of the drive motor. A housing is fitted around the drive motor and the water pump. The housing has a hollow pumping chamber inside, with an inlet and an outlet at each end. The other end of the water pump is located inside the pumping chamber. The drive motor includes a housing and a fan. One end of the housing has multiple cooling water inlets, and the other end has multiple cooling water outlets. The housing is connected to the pumping chamber through the cooling water inlets and outlets. A cooling water pipe is installed inside the housing. Both ends of the cooling water pipe are connected to the cooling water inlets and outlets, respectively. An air outlet is fixedly connected to one end face of the housing. A flow-limiting component is fixedly connected to the end of the housing near the air outlet. The fan is located inside the housing near the end of the air outlet.

[0007] By adopting the above technical solution, this device utilizes the water in the pumping chamber to form a circulating water-cooling structure through the cooling water inlet and outlet and the internal cooling water pipeline of the motor. Combined with fan-cooled heat dissipation, it achieves dual heat dissipation for the motor. This effectively solves the problems of excessive temperature rise and poor heat dissipation of traditional water supply motors during long-term low-speed operation. The current-limiting component adjusts the water inflow into the cooling water pipeline in coordination with the fan rotation. When the fan speed is high, the water inflow into the cooling water pipeline is reduced; when the fan speed is low, the water inflow into the cooling water pipeline is increased. This allows for adaptation to the heat dissipation intensity according to the water supply conditions, significantly improving the motor's operational stability and service life, and achieving energy-saving operation.

[0008] Preferably, the flow limiting component includes a flow guiding sleeve and a wind baffle ring; the flow guiding sleeve is fixedly installed inside the outer shell; the flow guiding sleeve is provided with multiple sets of flow guiding channels in its circumferential direction, and the wind baffle ring is located at one end of the flow guiding sleeve near the air outlet; the inner diameter of the wind baffle ring is smaller than the inner diameter of the flow guiding sleeve; and a flow control structure is provided inside the flow guiding channel.

[0009] By adopting the above technical solution, and by setting the guide sleeve and the small inner diameter wind baffle ring, the airflow blown out by the fan can be concentrated and guided, and the dispersed airflow can be accurately introduced into each group of guide channels to avoid airflow loss. This provides a stable and controllable airflow power for the subsequent airflow control structure, ensures the stability of airflow regulation, and ensures that the heat dissipation regulation function can accurately respond to changes in motor speed.

[0010] Preferably, the flow control structure includes a fixed block, which is a mesh structure. A spring is provided on one side of the fixed block, and a stop is provided at the free end of the spring. The cooling water pipe has a flow limiting port facing the flow guide channel. The stop is installed across the interior of the cooling water pipe and the flow guide channel through the flow limiting port, and the stop slides with the flow guide channel.

[0011] By adopting the above technical solution, the mesh fixing block can support airflow. The spring and the block slide together, and the block can automatically extend and retract by relying on the airflow thrust. With the flow limiting port, the area of ​​the block extending into the cooling water pipe can be dynamically changed, thereby adaptively limiting and regulating the cooling water flow. This allows the motor heat dissipation effect to be dynamically matched with the speed, reducing heat dissipation at high speeds and increasing heat dissipation at low speeds, effectively reducing equipment energy consumption.

[0012] Preferably, the cooling water inlet and the cooling water outlet are connected in a one-to-one correspondence, the cooling water pipeline is connected to the pumping chamber through the cooling water inlet and the cooling water outlet, and the cooling water pipeline is spirally laid around the inner wall of the outer shell.

[0013] By adopting the above technical solutions, the one-to-one correspondence of cooling water inlets and outlets ensures smooth water circulation. The spirally laid cooling water pipeline significantly extends the cooling water flow path, increases the contact area between the water and the motor casing, improves heat exchange efficiency, and fully wraps the motor's heat-generating area, resulting in better heat dissipation uniformity and further enhancing the overall heat dissipation performance of the motor.

[0014] Preferably, the inner wall of the flow channel is provided with an annular sealing groove, and a sealing ring is provided inside the annular sealing groove. The outer wall of the sealing ring protrudes from the opening of the annular sealing groove and fits against the outer peripheral wall of the block.

[0015] By adopting the above technical solution, the sealing ring built into the annular sealing groove is always in close contact with the outer periphery of the baffle, which can effectively seal the gap between the flow guide channel and the baffle, prevent cooling water leakage and airflow leakage, ensure the sealing of the water-cooled and air-cooled control structure, avoid the decrease in flow control accuracy due to air leakage and water leakage, and improve the reliability of equipment operation.

[0016] Preferably, the end face of the fixing block near the stop block and the corresponding end face of the stop block are both provided with positioning slots, the two sets of positioning slots are arranged opposite to each other, and the two ends of the spring are respectively engaged in the interior of the two sets of positioning slots.

[0017] By adopting the above technical solution, the positioning slots can limit and fix the two ends of the spring, preventing the spring from shifting, falling off, or twisting during the extension and contraction process, ensuring that the spring is subjected to uniform force, and allowing it to be replaced when its service life is exhausted.

[0018] Preferably, the upper and lower edges of the stop are fixedly connected to limit blocks, and the outer edges of the upper and lower sets of limit blocks abut against the inner wall of the guide channel.

[0019] By adopting the above technical solution, the limiting blocks set at the top and bottom of the baffle are fitted and limited to the inner wall of the guide channel, which can restrict the sliding trajectory of the baffle, prevent the baffle from tilting or getting stuck when sliding, and also prevent the baffle from exceeding the limit distance and coming out of the limiting port when it goes deep into the cooling water pipe or retracts into the guide channel. This improves the smoothness and control accuracy of the flow limiting adjustment and reduces the probability of structural failure.

[0020] Preferably, a partition pipe is provided inside the cooling water pipeline. The partition pipe is fixedly connected to the cooling water pipeline. The partition pipe adopts a hollow structure with uniform mesh holes and forms a sandwich cavity with the inner wall of the cooling water pipeline. The internal cavity of the sandwich cavity is filled with freely movable descaling balls.

[0021] By adopting the above technical solution, the perforated partition tube with mesh can form an independent sandwich cavity with the cooling water pipeline without affecting the flow of cooling water, providing space for the descaling ball to move, while not hindering water circulation and heat dissipation. The freely movable descaling ball can realize the automatic descaling function of the pipeline, and prevent scale buildup from clogging the pipeline.

[0022] Preferably, the inner sidewall of the outer shell is fixedly provided with a plurality of evenly distributed pipe clips, the plurality of pipe clips are arranged in an orderly manner along the setting trajectory of the cooling water pipes, and the cooling water pipes are correspondingly clipped and fixed inside the snap-fit ​​groove of each pipe clip.

[0023] By adopting the above technical solution, the orderly arranged pipe clamps can be used to fix the spiral cooling water pipes as a whole, limiting the shaking and displacement of the pipes during operation, avoiding the pipes from loosening, falling off, or wearing due to motor vibration, improving the structural stability and installation firmness of the cooling water pipes, and extending the service life of the heat dissipation structure.

[0024] Preferably, the outer surface of the descaling ball is uniformly provided with a plurality of protruding particles, and the plurality of protruding particles are fixedly arranged on the spherical surface of the descaling ball, and the diameter of the descaling ball is larger than the aperture of the partition mesh.

[0025] By adopting the above technical solution, the raised particles on the surface of the descaling ball can enhance the grinding and descaling effect. At the same time, the diameter of the ball is larger than the mesh of the partition pipe, which can effectively prevent the descaling ball from falling off or getting stuck in the mesh, ensuring that the descaling ball always moves freely in the jacket cavity, continuously colliding and grinding the inner wall of the pipeline and the partition pipe wall, effectively removing scale, ensuring smooth flow of cooling water, and stabilizing the heat dissipation and energy-saving effect of the equipment.

[0026] In summary, this application includes at least one of the following beneficial technical effects: 1. This device utilizes the water in the pumping chamber to form a circulating water-cooling structure through the cooling water inlet and outlet and the internal cooling water pipeline of the motor. Combined with fan cooling, it achieves dual heat dissipation for the motor. It effectively solves the problems of excessive temperature rise and poor heat dissipation of traditional water supply motors during long-term low-speed operation. The heat dissipation intensity can be adapted according to the water supply conditions, which greatly improves the stability and service life of the motor and achieves energy-saving operation.

[0027] 2. The mesh fixing block supports airflow. The spring and the block slide together, and the block can automatically extend and retract by relying on the airflow thrust. With the flow limiting port, the area of ​​the block extending into the cooling water pipe can be dynamically changed, thereby adaptively limiting and regulating the cooling water flow. This allows the motor heat dissipation effect to be dynamically matched with the speed, reducing heat dissipation at high speeds and increasing heat dissipation at low speeds, effectively reducing equipment energy consumption.

[0034] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0035] This application discloses an integrated energy-saving variable frequency induction motor for constant pressure water supply. (Refer to...) Figures 1 to 3The system includes a drive motor 2 and a water pump 1, with the water pump 1 located at the output end of the drive motor 2. A housing 3 surrounds the drive motor 2 and the water pump 1, and the housing 3 contains a hollow pumping chamber 31. Inlets 32 and outlets 33 are located at both ends of the housing 3. The other end of the water pump 1 is located inside the pumping chamber 31. The drive motor 2 includes a housing 21 and a fan 22. One end of the housing 21 has multiple sets of cooling water inlets 242, and the other end has multiple sets of cooling water outlets 243. The housing 21 is connected to the pumping chamber 31 through the cooling water inlets 242 and outlets 243. A cooling water pipe 24 is located inside the housing 21, with both ends connected to the cooling water inlets 242 and outlets 243, respectively. An air outlet 211 is fixedly connected to one end face of the outer casing 21. A flow limiting component 23 is fixedly connected to one end of the outer casing 21 near the air outlet 211. A fan 22 is located inside the outer casing 21 near the air outlet 211. When the drive motor 2 is running, the output end drives the water pump 1 to work, driving water to flow in from the inlet 32 ​​of the casing 3. Most of the water is pressurized by the water pump 1 and flows towards the outlet 33 of the casing 3. Another part of the water enters the cooling water pipe 24 inside the outer casing 21 from the cooling water inlet 242, flows along the cooling water pipe 24 and flows back to the pumping chamber 31 from the cooling water outlet 243. The fan 22 rotates synchronously with the shaft of the drive motor 2, driving the air inside the outer casing 21 to flow towards the air outlet 211. The airflow passes through the air outlet 211 and flows outward.

[0036] Reference Figures 3 to 4The flow limiting component 23 includes a flow guiding sleeve 231 and a wind baffle ring 232. The flow guiding sleeve 231 is fixedly installed inside the outer casing 21. The flow guiding sleeve 231 is circumferentially provided with multiple sets of flow guiding channels 233. The wind baffle ring 232 is located at one end of the flow guiding sleeve 231 near the air outlet net 211. The inner diameter of the wind baffle ring 232 is smaller than the inner diameter of the flow guiding sleeve 231. A flow control structure 234 is provided inside the flow guiding channel 233. The flow control structure 234 includes a fixing block 2341, which is a mesh structure. An annular sealing groove 2344 is opened around the inner sidewall of the flow guiding channel 233. A sealing ring 2345 is provided inside the annular sealing groove 2344. The outer sidewall of the sealing ring 2345 protrudes from the opening of the annular sealing groove 2344 and fits against the outer peripheral sidewall of the baffle block 2343. A spring 2342 is provided on one side of 41. A stop block 2343 is provided on the free end of the spring 2342. A positioning slot 2347 is provided on the end face of the fixed block 2341 near the stop block 2343 and the corresponding end face of the stop block 2343. The two sets of positioning slots 2347 are arranged opposite to each other. The two ends of the spring 2342 are respectively engaged in the interior of the two sets of positioning slots 2347. A flow limiting port 241 is opened in the cooling water pipe 24 towards the flow guide channel 233. The stop block 2343 is spanned in the interior of the cooling water pipe 24 and the flow guide channel 233 through the flow limiting port 241. The stop block 2343 slides in cooperation with the flow guide channel 233. The upper and lower edges of the stop block 2343 are fixedly connected to limit blocks 2346. The outer edges of the upper and lower sets of limit blocks 2346 abut against the inner wall of the flow guide channel 233.

[0037] Part of the airflow blown out by fan 22 enters the guide channel 233 of guide sleeve 231 due to the action of wind baffle ring 232; after passing through mesh fixing block 2341, the airflow acts on the end face of block 2343, pushing block 2343 to slide along the direction of guide channel 233; spring 2342 undergoes tensile deformation as block 2343 slides; block 2343 extends into cooling water pipe 24 through flow limiting port 241; limiting block 2346 slides synchronously with block 2343, sliding along the inner wall of guide channel 233; sealing ring 2345 is fixed in annular sealing groove 2344, and the inner ring is always in contact with the outer peripheral side wall of block 2343; when the speed of drive motor 2 increases... When the fan 22 speed increases synchronously, the airflow velocity and flow rate in the guide channel 233 also increase synchronously; the airflow thrust acting on the end face of the baffle 2343 increases, and the displacement of the baffle 2343 sliding into the cooling water pipe 24 increases, thus limiting the water flow in the cooling water pipe 24 and reducing the water cooling effect; when the drive motor 2 speed decreases, the fan 22 speed decreases synchronously, and the airflow velocity and flow rate in the guide channel 233 also decrease synchronously; the airflow thrust acting on the end face of the baffle 2343 decreases, the spring 2342 contracts and resets, pulling the baffle 2343 to slide in the direction of the guide channel 233, and the baffle 2343 retracts into the guide channel 233, increasing the water cooling effect.

[0038] Reference Figure 3 and Figure 5 The cooling water inlet 242 and cooling water outlet 243 are connected one-to-one. The cooling water pipe 24 is connected to the pumping chamber 31 through the cooling water inlet 242 and cooling water outlet 243. The cooling water pipe 24 is spirally laid around the inner wall of the outer shell 21. Several evenly distributed pipe clips 247 are fixedly installed on the inner side wall of the outer shell 21. The pipe clips 247 are arranged in an orderly manner along the installation trajectory of the cooling water pipe 24. The cooling water pipe 24 is correspondingly fixed in the snap-fit ​​groove of each pipe clip 247. A partition pipe 244 is installed along the inside of the cooling water pipe 24. The partition pipe 244 is fixedly connected to the cooling water pipe 24. The partition pipe 244 adopts a hollow structure with uniform mesh holes and forms a sandwich cavity 245 with the inner wall of the cooling water pipe 24. The internal cavity of the sandwich cavity 245 is filled with freely movable descaling balls 246. The outer surface of the descaling balls 246 is evenly decorated with... Several protruding particles 248 are fixedly arranged on the spherical surface of the descaling ball 246. The diameter of the descaling ball 246 is larger than the aperture of the mesh of the separator tube 244. The vibration generated by the operation of the drive motor 2 is transmitted to the cooling water pipe 24 and the separator tube 244 through the outer shell 21. The descaling ball 246 moves randomly in the interlayer cavity 245 under the action of vibration, rolling and colliding with the inner wall of the cooling water pipe 24 and the outer wall of the separator tube 244. After the water enters the cooling water pipe 24 from the cooling water inlet 242, it flows through the mesh of the separator tube 244, along the channel of the separator tube 244 and the interlayer cavity 245, impacting the descaling ball 246 and causing it to move additionally. The protruding particles 248 on the surface of the descaling ball 246 move synchronously with the ball and continuously contact the inner wall of the cooling water pipe 24 and the surface of the separator tube 244, thus removing the scale on the inner wall of the cooling water pipe 24 and the wall of the separator tube 244.

[0039] The working principle of the integrated constant pressure water supply energy-saving variable frequency induction motor in this application is as follows: When the equipment is running, the drive motor 2 drives the water pump 1 in the pumping chamber 31 to operate synchronously, so that water flows in from the inlet 32 ​​of the shell 3. Most of the water is pressurized by the water pump 1 and discharged from the outlet 33 of the shell 3. A small part of the water enters the spiral cooling water pipe 24 inside the motor shell 21 through the corresponding connected cooling water inlet 242, and finally flows back to the pumping chamber 31 from the cooling water outlet 243, completing the water circulation and heat dissipation. At the same time, the motor shaft drives the fan 22 to rotate synchronously, driving the air in the shell 3 to flow towards the air outlet 211. Part of the airflow is guided by the wind baffle ring 232 into the guide channel 233 of the guide sleeve 231, passes through the mesh fixing block 2341 and pushes the stop block 2343 to slide, stretching the spring. Spring 2342 allows stop block 2343 to pass through flow limiting port 241 and penetrate into cooling water pipe 24, achieving smooth sliding in conjunction with limit block 2346. Sealing ring 2345 always fits against stop block 2343 to ensure sealing. The water cooling effect can be automatically adjusted according to changes in motor speed: when the speed increases, the airflow thrust increases, the displacement of stop block 2343 into the pipe increases, and the flow limiting effect is reduced; when the speed decreases, the airflow thrust decreases, spring 2342 resets, stop block 2343 retracts, and the water cooling heat dissipation effect is enhanced. During operation, motor vibration and water flow impact will cause the descaling ball 246 in the jacket cavity 245 of cooling water pipe 24 to roll and collide irregularly. The raised particles 248 on their surface continuously polish the inner wall of the pipe and the wall of the partition pipe 244, removing scale in real time, ensuring smooth heat dissipation pipe and stable equipment operation.

[0040] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
