Technical Field
[0001] This invention belongs to the technical field of high-voltage motors for water pumps, and particularly relates to a high-voltage motor for water pumps. Background Technology
[0002] In the industrial production field, the high-voltage motor for water pumps is the core power component of the fluid transportation system. Its "specialization" is mainly reflected in the waterproof structural design that is adapted to the fluid environment. This structure directly determines the safety and durability of the equipment operation. In the existing technology, in order to achieve a compact layout, the high-voltage motor and water pump are usually integrated in parallel. Although the connection between the two needs to bear the function of waterproof sealing, there is generally a lack of a special waterproof structural design.
[0003] Currently, high-voltage motors and water pumps mostly rely on conventional threaded connections for connection and sealing. This structure does not consider the dynamic waterproofing requirements during equipment operation. In actual working conditions, the electromagnetic vibration of the high-voltage motor and the fluid pulsation of the water pump will form a continuous compound excitation, causing fatigue wear of the seals at the threaded interface due to high-frequency alternating stress, which in turn leads to seal failure. Due to the lack of compensation and protection design for a dedicated waterproof structure, leakage is very likely to occur here, which not only increases the equipment maintenance cost, but also the fluid transported by the water pump often contains solid impurities such as mud, sand, and metal debris. The existing connection structure does not integrate waterproofing and impurity prevention functions through a dedicated structure design, so impurities can easily enter the high-voltage motor with the leaking water flow, aggravating the wear and corrosion of key components. This lack of a dedicated waterproof structure makes the failure rate of the motor significantly higher when operating in humid and impurity-rich fluid environments, making it difficult to meet the special waterproofing requirements of specialized equipment. In view of this, we propose a high-voltage motor specifically for water pumps. Summary of the Invention
[0004] The purpose of this invention is to provide a high-voltage motor specifically for water pumps to solve the problems mentioned in the background art.
[0005] In view of this, the present invention provides a high-voltage motor for water pumps, comprising: The high-voltage motor body has a water pump body on one side and a water cooling plate on the high-voltage motor body. A connector is fixedly installed on the high-voltage motor body. One end of the connector has a snap-fit groove. A connecting pipe is inserted into the snap-fit groove. A sealing ring one is fixedly installed on one side of the snap-fit groove. A sealing ring two is fixedly installed on one end of the connecting pipe. Limiting grooves are symmetrically opened on the inner wall of the snap-fit groove. Limiting blocks are fixedly installed on the periphery of the connecting pipe and in each of the two limiting grooves. A limiting ring is fixedly installed on the periphery of the connecting pipe and located at one end of the connector. A threaded sleeve is fitted on the limiting ring, one end of which extends to the connector. A rubber ring is fixedly installed on the inner wall of the threaded sleeve. A limiting component, located inside the connecting pipe, is used to limit the connection pipe and the threaded sleeve; A filter tube is fixedly installed at the other end of a connecting pipe, and a water supply pipe is fixedly installed at one end of the filter tube. One end of the water supply pipe is fixed to the water pump body. A filter assembly located inside a filter tube and used to filter water.
[0006] In this technical solution, during installation, the operator inserts one end of the connecting pipe into the snap-fit groove and aligns the positions of the two limiting blocks and two limiting slots. The two limiting blocks and two limiting slots limit the connection of the connecting pipe, ensuring stability during insertion. This continues until one end of the connecting pipe is fully inserted into the snap-fit groove. At this point, the limiting component further limits the connection, and the second sealing ring tightly fits against the first sealing ring. The sealing effect of the first and second sealing rings prevents leakage. Then, the threaded sleeve is placed on the connector and rotated. The threads tighten the threaded sleeve onto the connector. When the rubber ring inside the threaded sleeve is tightly fitted onto the limiting ring, the limiting component can limit the threaded sleeve, ensuring that the threaded sleeve will not loosen due to vibration. It can effectively compensate for the vibration displacement of the high-voltage motor body and the water pump body during operation, avoid fatigue wear of the seal caused by alternating stress in traditional threaded connections, and form a three-dimensional waterproof barrier. Even under long-term compound excitation conditions, it can still maintain reliable sealing of the connection parts, greatly reduce the risk of water leakage, fundamentally solve the damage to the motor pipe and end cover caused by vibration transmission, and avoid irreversible structural damage that may occur at the end cover sealing groove. During use, the water pumped by the pump body passes through the filter tube, and the filter components inside the filter tube can filter the water, intercepting impurities such as mud, sand and metal fragments in the fluid. At the same time, the barrier effect of the waterproof structure prevents impurities from entering the high-voltage motor body with the water flow. This integrated design not only avoids the wear of impurities on the seals, but also prevents them from entering the high-voltage motor body and aggravating component wear. It significantly improves the anti-fouling ability of the high-voltage motor body in a multi-impurity fluid environment. The water in the connector can dissipate heat from the output shaft of the high-voltage motor body through the water cooling plate.
[0007] In the above technical solution, the limiting component further includes: Two sliding grooves are symmetrically opened inside the connecting pipe. A sliding block is slidably installed in the sliding groove. Limiting holes are symmetrically opened on the periphery of the connector. One end of the sliding block passes through the sliding groove and extends into the corresponding limiting hole. A spring that is fixed to the inner wall of the sliding groove is fixedly installed at the other end of the sliding block. Two sliding grooves are symmetrically opened inside the connecting pipe and located on one side of the threaded sleeve. A blocking block is slidably installed in the sliding groove. One end of the blocking block passes through the sliding groove and abuts against the threaded sleeve. The other end of the blocking block is fixedly installed with a spring that is fixed to the inner wall of the sliding groove.
[0008] In this technical solution, during installation, the operator inserts one end of the connecting pipe into the snap-fit groove and aligns it with the positions of the two limiting blocks and two limiting slots. The two limiting blocks and two limiting slots limit the connection of the connecting pipe, ensuring stability during insertion. At this time, the inner wall of the snap-fit groove will press the two sliding blocks to move. The movement of the sliding blocks will compress the first spring, causing it to contract until one end of the connecting pipe is fully inserted into the snap-fit groove. Then, under the rebound force of the two first springs, they will press the two sliding blocks to move until one end of each sliding block is inserted into the two limiting holes. At this point, the two sliding blocks limit the connection of the connecting pipe, and the second sealing ring will tightly fit against the first sealing ring. The sealing effect of the first and second sealing rings ensures no leakage. Then, the threaded sleeve is placed on the connector and rotated. The threaded sleeve... When screwed onto the connector, the movement of the threaded sleeve compresses two blocking blocks, causing them to move. The movement of these blocking blocks, in turn, compresses spring two, causing it to contract. When the rubber ring inside the threaded sleeve is tightly fitted onto the limiting ring, the two springs, under their rebound force, will compress the two blocking blocks to reset until both blocking blocks are against one side of the threaded sleeve, thus limiting its position and preventing it from loosening due to vibration. This effectively compensates for the vibration displacement of the high-voltage motor body and the water pump body during operation, avoiding fatigue wear of the seals caused by alternating stress in traditional threaded connections. The multi-level sealing design forms a three-dimensional waterproof barrier, maintaining reliable sealing at the connection even under long-term combined excitation conditions, significantly reducing the risk of leakage. It fundamentally solves the problem of damage to the motor pipes and end caps caused by vibration transmission, and avoids irreversible structural damage that may occur at the end cap sealing groove.
[0009] In the above technical solution, one end of the sliding block is inserted into the limiting hole, and one end of the sliding block has an arc-shaped structure. One end of the blocking block is engaged with the threaded sleeve, and one end of the blocking block has an inclined structure.
[0010] In this technical solution, it is ensured that one end of the sliding block can be inserted into the limiting hole, that the inner wall of the snap-fit groove can squeeze the sliding block to move, that one end of the blocking block can lock the threaded sleeve, and that the movement of the threaded sleeve can squeeze the blocking block to move.
[0011] In the above technical solution, the filtering component further includes: Two insertion slots are provided, both of which are located inside the filter tube. A filter screen is inserted and installed in the insertion slot. A sealing plate is provided at the top of the filter tube. A sealing gasket is fixedly installed at the bottom of the sealing plate. Two hexagonal socket screws are symmetrically inserted and installed on the sealing plate. The bottom end of the hexagonal socket screws extends into the filter tube.
[0012] In this technical solution, during use, the water pumped by the pump body passes through the filter pipe, and the two filter screens inside the filter pipe can filter the water, intercepting impurities such as mud, sand, and metal fragments in the fluid. At the same time, the barrier effect of the waterproof structure prevents impurities from entering the high-voltage motor body with the water flow. This integrated design not only avoids the wear of impurities on the seals, but also prevents them from entering the high-voltage motor body and aggravating component wear. It significantly improves the anti-fouling ability of the high-voltage motor body in a multi-impurity fluid environment. The water in the connector can dissipate heat from the output shaft of the high-voltage motor body through the water cooling plate.
[0013] In the above technical solution, the sealing gasket abuts against the top of the two filter screens and the periphery of the filter tube, and the bottom end of the internal hexagon screw is threadedly connected to the filter tube.
[0014] In this technical solution, the sealing gasket is ensured to seal the filter tube, preventing water leakage and ensuring that the internal hex screws can be screwed into the filter tube.
[0015] In the above technical solution, a second water delivery pipe is further fixedly installed on the water pump body.
[0016] In this technical solution, the structural stability of the water pump body and the second water delivery pipe is ensured.
[0017] In the above technical solution, the sealing ring one and the sealing ring two are tightly fitted, the limiting block and the limiting groove are inserted into each other, the threaded sleeve is threadedly connected to the connector, and the rubber ring abuts against the limiting ring.
[0018] In this technical solution, it is ensured that there will be no water leakage under the sealing effect of sealing ring one and sealing ring two, that the limiting block can be inserted into the limiting groove, that the threaded sleeve can be screwed onto the connector, and that the structure of the rubber ring and the limiting ring is stable.
[0019] In the above technical solution, the connector is further connected to the connecting pipe, the filter pipe and the water supply pipe.
[0020] In this technical solution, it is ensured that the water in the connector, connecting pipe, filter pipe, and water supply pipe can flow normally.
[0021] The beneficial effects of this invention are: 1. This high-voltage motor for water pumps, through its specially designed waterproof structure, can effectively compensate for the vibration displacement of the high-voltage motor body and the water pump body during operation. It avoids fatigue wear of the seals caused by alternating stress in traditional threaded connections. The multi-level sealing design can form a three-dimensional waterproof barrier, which can maintain reliable sealing of the connection parts even under long-term compound excitation conditions, greatly reducing the risk of water leakage. It fundamentally solves the damage to the motor pipes and end caps caused by vibration transmission and avoids irreversible structural damage that may occur at the end cap sealing groove.
[0022] 2. The pump body is equipped with a dedicated high-pressure motor body. The special structure integrates waterproof sealing and impurity filtration functions. The built-in filter components intercept impurities such as mud, sand, and metal fragments in the fluid. At the same time, the barrier effect of the waterproof structure prevents impurities from entering the high-pressure motor body with the water flow. This integrated design not only avoids the wear of impurities on the seals, but also prevents them from entering the high-pressure motor body and aggravating component wear. It significantly improves the anti-fouling ability of the high-pressure motor body in multi-impurity fluid environments.
[0023] 3. The water pump body is equipped with a dedicated high-voltage motor body, and the filter assembly adopts a modular quick-release structure design. It does not require disassembling the main connection between the high-voltage motor body and the water pump body, and the filter screen can be installed and removed separately, which further improves the convenience of equipment maintenance and the continuity of operation.
[0024] 4. The pump body is equipped with a dedicated high-pressure motor body. Thanks to its reliable waterproof and impurity-proof performance, the corrosion and wear rate of key components of the high-pressure motor body is greatly reduced, and the failure rate is significantly decreased. At the same time, the dedicated structure reduces the number of downtime maintenance caused by seal failure and filter replacement, extends the continuous operation time of the equipment, and improves the overall operating efficiency of the fluid transportation system.

[0032] Example 1: Please see Figures 1-11 As shown, this embodiment provides a high-voltage motor specifically for water pumps, including: The high-voltage motor body 1 has a water pump body 3 on one side, a water cooling plate 2 on the high-voltage motor body 1, a connector 4 fixedly installed on the high-voltage motor body 1, a snap-fit groove 5 at one end of the connector 4, a connecting pipe 6 inserted into the snap-fit groove 5, a sealing ring 9 fixedly installed on one side of the snap-fit groove 5, a sealing ring 10 fixedly installed at one end of the connecting pipe 6, symmetrical limit grooves 7 on the inner wall of the snap-fit groove 5, and limit blocks 8 fixedly installed on the periphery of the connecting pipe 6 and in the two limit grooves 7 respectively. A limiting ring 15 is fixedly installed on the periphery of the connecting pipe 6 and located at one end of the connector 4. A threaded sleeve 16 is fitted on the limiting ring 15, one end of which extends to the connector 4. A rubber ring 17 is fixedly installed on the inner wall of the threaded sleeve 16. A limiting component is located inside the connecting pipe 6 and is used to limit the connecting pipe 6 and the threaded sleeve 16. Filter tube 21 is fixedly installed at the other end of connecting pipe 6. One end of filter tube 21 is fixedly installed with water supply pipe 27. One end of water supply pipe 27 is fixed to water pump body 3. A filter assembly is located inside the filter tube 21 and is used to filter water.
[0033] During installation, the operator inserts one end of the connecting pipe 6 into the snap-fit groove 5, aligning it with the positions of the two limiting blocks 8 and the two limiting grooves 7. The two limiting blocks 8 and the two limiting grooves 7 limit the connection of the connecting pipe 6, ensuring its smooth insertion. This continues until one end of the connecting pipe 6 is fully inserted into the snap-fit groove 5. At this point, the limiting component further limits the connection of the connecting pipe 6, and the second sealing ring 10 will tightly adhere to the first sealing ring 9. The sealing effect of the first sealing ring 9 and the second sealing ring 10 prevents leakage. Then, the threaded sleeve 16 is placed on the connector 4 and rotated. The threads tighten the threaded sleeve 16 onto the connector. On the head 4, when the rubber ring 17 inside the threaded sleeve 16 is tightly fitted to the limiting ring 15, the limiting component can limit the threaded sleeve 16 to ensure that the threaded sleeve 16 will not loosen due to vibration. It can effectively compensate for the vibration displacement of the high-voltage motor body 1 and the water pump body 3 during operation, avoid fatigue wear of the seal caused by alternating stress in traditional threaded connections, and form a three-dimensional waterproof barrier. Even under long-term compound excitation conditions, it can still maintain reliable sealing of the connection parts, greatly reduce the risk of water leakage, fundamentally solve the damage to the motor pipe and end cover caused by vibration transmission, and avoid irreversible structural damage that may occur at the end cover sealing groove. During use, the water pump body 3 delivers water through the filter pipe 21, and the filter components inside the filter pipe 21 can filter the water, intercepting impurities such as mud, sand and metal fragments in the fluid. At the same time, the barrier effect of the waterproof structure prevents impurities from entering the high-voltage motor body 1 with the water flow. This integrated design not only avoids the wear of impurities on the seals, but also prevents them from entering the interior of the high-voltage motor body 1 and aggravating component wear, significantly improving the anti-fouling ability of the high-voltage motor body 1 in a multi-impurity fluid environment. The water in the connector 4 can dissipate heat to the output shaft of the high-voltage motor body 1 through the water cooling plate 2.
[0034] Example 2: This embodiment provides a high-voltage motor specifically for water pumps. In addition to the technical solutions described in the above embodiments, it also has the following technical features, including a limiting component: Two sliding grooves 11 are symmetrically opened in the connecting pipe 6. A sliding block 12 is slidably installed in the sliding groove 11. Limiting holes 13 are symmetrically opened on the periphery of the connector 4. One end of the sliding block 12 passes through the sliding groove 11 and extends into the corresponding limiting hole 13. A spring 14 fixed to the inner wall of the sliding groove 11 is fixedly installed at the other end of the sliding block 12. Two slides 18 are symmetrically opened inside the connecting pipe 6 and located on one side of the threaded sleeve 16. A blocking block 19 is slidably installed inside the slide 18. One end of the blocking block 19 passes through the slide 18 and abuts against the threaded sleeve 16. The other end of the blocking block 19 is fixedly installed with a spring 20 that is fixed to the inner wall of the slide 18.
[0035] During installation, the operator inserts one end of the connecting pipe 6 into the snap-fit groove 5, aligning it with the positions of the two limiting blocks 8 and the two limiting grooves 7. The two limiting blocks 8 and the two limiting grooves 7 limit the connection of the connecting pipe 6, ensuring stability during insertion. At this time, the inner wall of the snap-fit groove 5 presses against the two sliding blocks 12, causing them to move. The movement of the sliding blocks 12 compresses the spring 14, causing it to contract until one end of the connecting pipe 6 is fully inserted into the snap-fit groove 5. Then, under the rebound force of the two springs 14, they press against the two sliding blocks 12, causing them to move until one end of each sliding block 12 is inserted into the two limiting holes 13. At this point, the two sliding blocks 12 limit the connection of the connecting pipe 6, and the sealing ring 2 10 tightly adheres to the sealing ring 9. The sealing effect of the sealing rings 9 and 2 10 ensures no leakage. Then, the threaded sleeve 16 is placed on the connector 4 and rotated. The threaded sleeve... When threaded sleeve 16 is screwed onto connector 4, its movement will press against two blocking blocks 19, causing them to move. The movement of the blocking blocks 19 will also press against spring 20, causing it to contract. When the rubber ring 17 inside threaded sleeve 16 is tightly fitted onto limit ring 15, the two springs 20 will then press against the two blocking blocks 19 to reset under the rebound force of the two springs 20 until both blocking blocks 19 are against one side of threaded sleeve 16, thus limiting threaded sleeve 16 and ensuring that it will not loosen due to vibration. This effectively compensates for the vibration displacement of high-voltage motor body 1 and water pump body 3 during operation, avoids fatigue wear of seals caused by alternating stress in traditional threaded connections, and the multi-level sealing design forms a three-dimensional waterproof barrier. Even under long-term compound excitation conditions, it can still maintain reliable sealing of the connection, significantly reducing the risk of leakage and fundamentally solving the damage to motor pipes and end caps caused by vibration transmission, avoiding irreversible structural damage that may occur at the end cap sealing groove.
[0036] Example 3: This embodiment provides a high-voltage motor for water pumps. In addition to the technical solutions of the above embodiments, it also has the following technical features: one end of the sliding block 12 is inserted into the limiting hole 13, one end of the sliding block 12 has an arc-shaped structure, one end of the blocking block 19 is engaged with the threaded sleeve 16, and one end of the blocking block 19 has an inclined structure.
[0037] Specifically, it is ensured that one end of the sliding block 12 can be inserted into the limiting hole 13, that the inner wall of the snap-fit groove 5 can squeeze the sliding block 12 to move, that one end of the blocking block 19 can lock the threaded sleeve 16, and that the movement of the threaded sleeve 16 can squeeze the blocking block 19 to move.
[0038] Example 4: This embodiment provides a high-voltage motor specifically for water pumps. In addition to the technical solutions described in the above embodiments, it also has the following technical features: the filter assembly includes: Two insertion slots 22 are provided inside the filter tube 21. Filter screens 23 are inserted and installed in the insertion slots 22. A sealing plate 24 is provided at the top of the filter tube 21. A sealing gasket 25 is fixedly installed at the bottom of the sealing plate 24. Two hexagon socket screws 26 are symmetrically inserted and installed on the sealing plate 24. The bottom ends of the hexagon socket screws 26 extend into the filter tube 21.
[0039] During use, the water pump body 3 delivers water through the filter pipe 21, where two filter screens 23 filter the water, intercepting impurities such as mud, sand, and metal fragments. At the same time, the barrier effect of the waterproof structure prevents impurities from entering the high-voltage motor body 1 with the water flow. This integrated design avoids wear on the seals caused by impurities and prevents them from entering the high-voltage motor body 1 and aggravating component wear. It significantly improves the anti-fouling ability of the high-voltage motor body 1 in a multi-impurity fluid environment. The water in the connector 4 can dissipate heat from the output shaft of the high-voltage motor body 1 through the water cooling plate 2.
[0040] Example 5: This embodiment provides a high-pressure motor for water pumps. In addition to the technical solutions of the above embodiments, it also has the following technical features: the sealing gasket 25 abuts against the top of the two filter screens 23 and the periphery of the filter tube 21, and the bottom end of the internal hexagon screw 26 is threadedly connected to the filter tube 21.
[0041] Specifically, this ensures that the sealing gasket 25 can seal the filter tube 21, prevents water leakage from the filter tube 21, and ensures that the internal hex screw 26 can be screwed into the filter tube 21.
[0042] Example 6: This embodiment provides a high-voltage motor for water pumps. In addition to the technical solutions of the above embodiments, it also has the following technical features: a water delivery pipe 28 is fixedly installed on the water pump body 3.
[0043] Among these measures, it is essential to ensure the structural stability of the water pump body 3 and the water delivery pipe 28.
[0044] Example 7: This embodiment provides a high-voltage motor for water pumps. In addition to the technical solutions of the above embodiments, it also has the following technical features: sealing ring 9 and sealing ring 10 are tightly fitted together; limiting block 8 and limiting groove 7 are inserted and matched; threaded sleeve 16 is threadedly connected to connector 4; and rubber ring 17 abuts against limiting ring 15.
[0045] Among these measures, it is ensured that there will be no water leakage under the sealing effect of sealing ring 9 and sealing ring 10, that the limiting block 8 can be inserted into the limiting groove 7, that the threaded sleeve 16 can be screwed onto the connector 4, and that the structure of the rubber ring 17 and the limiting ring 15 is stable.
[0046] Example 8: This embodiment provides a high-voltage motor for water pumps. In addition to the technical solutions of the above embodiments, it also has the following technical features: the connector 4 is connected to the connecting pipe 6, the filter pipe 21 and the water supply pipe 27.
[0047] This ensures that the water in the connector 4, connecting pipe 6, filter pipe 21, and water supply pipe 27 can flow normally.
[0048] It is worth noting that the high-voltage motor for water pumps is a special type of motor designed specifically to drive various high-pressure water pumps. Its core function is to efficiently convert electrical energy into mechanical energy, providing a continuous, stable, and high-torque power output for the high-pressure water pump. This meets the high-pressure, high-flow liquid transportation needs in industrial production, municipal water supply, and energy supply scenarios. Furthermore, it is specifically optimized for the high load characteristics commonly encountered during pump startup, with optimized starting torque and short-term overload capacity. This effectively prevents motor failure or damage due to excessive starting load. Considering that water pumps often operate in humid, dusty, and even corrosive environments such as pump rooms, water treatment plants, and power plants, these motors typically employ an IP54 or higher protection rating. Some key components also undergo additional anti-corrosion treatment to extend their service life. In addition, through the use of high-efficiency core materials and optimized winding structures, the motor efficiency generally meets or exceeds the national level 2 energy efficiency standard. This helps reduce the overall energy consumption cost of the water pump system during long-term operation. It is widely applicable to various high-pressure water pump equipment, such as industrial cooling circulating water pumps, municipal water supply main pumps, and thermal power plant condensate pumps.
[0049] It is worth noting that the output shaft of the high-voltage motor body 1 is coaxially connected to the power shaft of the water pump body 3, ensuring that the output shaft of the high-voltage motor body 1 can drive the water pump body 3 to operate normally.
[0050] Working principle: During installation, the operator inserts one end of the connecting pipe 6 into the snap-fit groove 5 and aligns it with the positions of the two limiting blocks 8 and the two limiting grooves 7. The two limiting blocks 8 and the two limiting grooves 7 limit the connecting pipe 6, ensuring the stability of the connection. At this time, the inner wall of the snap-fit groove 5 will press the two sliding blocks 12 to move. The movement of the sliding blocks 12 will compress the spring 14 to retract until one end of the connecting pipe 6 is fully inserted into the snap-fit groove 5. At this time, under the rebound force of the two springs 14, the two springs 14 will press the two sliding blocks 12 to move until one end of the two sliding blocks 12 is inserted into the two limiting holes 13. At this time, the two sliding blocks 12 can limit the connecting pipe 6. At the same time, the sealing ring 2 10 will be tightly fitted onto the sealing ring 9. Under the sealing effect of the sealing ring 9 and the sealing ring 2 10, water leakage is prevented. Then, the threaded sleeve 16 is put on the connector 4 and rotated. Under the action of the thread, the thread can be... Sleeve 16 is screwed onto connector 4. Simultaneously, the movement of threaded sleeve 16 will compress two blocking blocks 19, causing them to move. The movement of blocking blocks 19 will compress spring 20, causing it to contract. When the rubber ring 17 inside threaded sleeve 16 is tightly fitted onto limit ring 15, under the action of the rebound force of two springs 20, the two springs 20 will respectively compress the two blocking blocks 19 to reset until both blocking blocks 19 are against one side of threaded sleeve 16, thereby limiting threaded sleeve 16 and ensuring that threaded sleeve 16 will not loosen due to vibration. This can effectively compensate for the vibration displacement of high-voltage motor body 1 and water pump body 3 during operation, avoid fatigue wear of seals caused by alternating stress in traditional threaded connections, and form a three-dimensional waterproof barrier. Even under long-term compound excitation conditions, it can still maintain reliable sealing of the connection parts, greatly reducing the risk of water leakage, fundamentally solving the damage to motor pipes and end caps caused by vibration transmission, and avoiding irreversible structural damage that may occur at the end cap sealing groove. During use, the water pump body 3 delivers water through the filter pipe 21, and the two filter screens 23 inside the filter pipe 21 can filter the water, intercepting impurities such as mud, sand and metal fragments in the fluid. At the same time, the barrier effect of the waterproof structure prevents impurities from entering the high-voltage motor body 1 with the water flow. This integrated design not only avoids the wear of impurities on the seals, but also prevents them from entering the interior of the high-voltage motor body 1 and aggravating component wear, significantly improving the anti-fouling ability of the high-voltage motor body 1 in a multi-impurity fluid environment. The water in the connector 4 can cool the bearing in the water cooling plate 2 through the water cooling plate 2 and the return pipe, ensuring that the high-voltage motor body 1 will not overheat. At the same time, the rotation of the output shaft of the high-voltage motor body 1 can drive the fan blades inside the water pump body 3 to rotate, thereby ensuring that the water pump body 3 can operate normally. When the filtration effect of the two filter screens 23 deteriorates after prolonged use, personnel can use tools to turn the four hexagonal screws 26. Under the action of the threads, the four hexagonal screws 26 can be unscrewed from the filter tube 21, thereby releasing the sealing plate 24 from its fixation. The sealing plate 24 can then be removed, and the two filter screens 23 can be pulled out from the two insertion slots 22 and replaced. After replacement, the sealing plate 24 is put back on the filter tube 21, and the four hexagonal screws 26 are screwed into the filter tube 21. With the sealing gasket 25 sealing the filter tube 21, there will be no leakage. The two filter screens 23 adopt a modular quick-release structure design, which eliminates the need to disassemble the main connection between the high-pressure motor body 1 and the water pump body 3. This allows for the individual disassembly and assembly of the filter screens 23, further improving the convenience of equipment maintenance and the continuity of operation.
