Description

Technical Field

[0001] This utility model relates to centrifugal pumps, and more particularly to an AC permanent magnet machine tool water pump. Background Technology

[0002] A centrifugal pump is a pump that uses the centrifugal force generated by the rotation of an impeller to transport liquids. A multistage centrifugal pump is a combination of two or more centrifugal pumps with the same function. In terms of fluid channel structure, the medium pressure relief port of the first stage is connected to the inlet of the second stage, and the medium pressure relief port of the second stage is connected to the inlet of the third stage. This series connection forms a multistage centrifugal pump. Multistage centrifugal pumps can meet different requirements by changing the number of pump stages (i.e., changing the number of impellers), so they have a wide range of applications.

[0003] Multistage centrifugal pumps mainly consist of a motor, pump base, shaft, guide vane, and impeller. The high-speed rotation of the motor drives the shaft via a coupling, which in turn drives the impeller. Liquid is drawn into the first-stage impeller and then guided through the guide vane to the inlet of the next-stage impeller, and so on, thus continuously increasing the liquid's energy and achieving a higher head. The pump base has an output connector for connecting to a water pipe, with internal threads to strengthen the connection. However, current multistage centrifugal pump motors operate at a constant speed, unable to adjust their speed according to water flow and temperature, and therefore cannot flexibly adapt to production needs. Furthermore, the motor is typically connected to a driver, which controls the motor's operation under certain conditions, but the driver and motor are located in different parts, resulting in a fragmented structure.

[0004] Therefore, there is an urgent need for an AC permanent magnet machine tool water pump with a compact structure that can adjust its rotation speed according to the temperature and flow rate of the output water to overcome the above-mentioned defects. Utility Model Content

[0005] The purpose of this invention is to provide an AC permanent magnet machine tool water pump with a compact structure that can adjust its rotation speed according to the temperature and flow rate of the output water.

[0006] To achieve the above objectives, the AC permanent magnet machine tool water pump provided by this utility model includes a motor, a rotating shaft, a driver, a pump base, and several stages of centrifugal pump bodies connected in sequence. The pump base includes a base body and an output connector connected to the base body and offset outward from the base body. The base body has a through mounting hole extending vertically. The output connector and the base body have an output flow channel. The motor is mounted on the top of the pump base. The rotating shaft is mounted in the through mounting hole and is rotatably mounted on the pump base. The rotating shaft is connected to the output end of the motor, and the motor drives the rotating shaft to rotate. The centrifugal pump bodies are mounted on the bottom of the pump base and are connected to the rotating shaft. The driver is mounted on the top of the motor and is electrically connected to the motor. The pump base has a fixing hole opening into the output flow channel. A flow sensor and / or a temperature sensor are installed in the fixing hole. The flow sensor and / or temperature sensor are electrically connected to the driver.

[0007] Preferably, the output flow channel includes a first flow channel portion disposed within the pump base and a second flow channel portion disposed within the output connector, with the fixing hole opening in the first flow channel portion.

[0008] Preferably, the second flow channel section has a threaded structure for connecting with the water pipe.

[0009] Preferably, the outer surface of the driver is a circular side.

[0010] Preferably, the four sides of the driver are located within the space defined by the outer side of the motor.

[0011] Preferably, the output channel extends to the bottom of the base and is arranged in a bent manner.

[0012] Preferably, the outer side wall of the output connector is chamfered.

[0013] Preferably, the base includes an upper base structure, a middle base structure, and a lower base structure connected sequentially from top to bottom. The upper base structure and the lower base structure are hollowed out, and the mounting through hole runs through the upper base structure, the middle base structure, and the lower base structure from top to bottom.

[0014] Preferably, the upper structure is connected to the middle structure through several upper connectors, and the upper structure and the middle structure enclose an upper structure space. The upper connectors are spaced apart and form an upper structure gap that communicates with the upper structure space between them.

[0015] Preferably, the middle support structure is connected to the lower support structure through several lower connecting bodies, and a lower structure space is enclosed between the middle support structure and the lower support structure. The lower connecting bodies are arranged at intervals and form a lower structure gap that communicates with the lower structure space between them.

[0016] Compared with existing technologies, this invention features a fixing hole in the pump base that opens into the output flow channel. A flow sensor and / or temperature sensor are installed in this hole, electrically connected to a driver, which in turn is electrically connected to a motor. The motor drives the shaft to rotate, thereby rotating the centrifugal pump body and pumping water into the output flow channel. As the water flows through the output flow channel, the flow sensor detects the water flow rate, and the temperature sensor detects the water temperature. These parameters are fed back to the driver, which then controls the motor speed accordingly, flexibly adapting to production needs. Furthermore, the driver is mounted on top of the motor, controlling its speed, power, and other parameters, resulting in a more compact structure. Attached Figure Description

[0022] To explain the technical content and structural features of this utility model in detail, the following description is provided in conjunction with the embodiments and accompanying drawings.

[0023] like Figures 1 to 5 As shown, this utility model provides an AC permanent magnet machine tool water pump 100, including a motor 10, a rotating shaft 20, a driver 30, a pump base 40, and several stages of centrifugal pump bodies 50 connected in sequence. The pump base 40 includes a base body 41 and an output connector 42 connected to the base body 41 and offset outward from the base body 41. The base body 41 has a through mounting hole 411 extending vertically, and the output connector 42 and the base body 41 have an output flow channel 43. The motor 10 is mounted on the top of the pump base 40, and the rotating shaft 20 is mounted in the through mounting hole 411 and rotatably mounted on the pump base 40. The rotating shaft 20 is connected to the output end of the motor 10, and the motor 10 drives the rotating shaft 20 to rotate. The centrifugal pump body 50 is installed at the bottom of the pump base 40 and is connected to the rotating shaft 20. The driver 30 is installed on the top of the motor 10 and is electrically connected to the motor 10. The pump base 40 has a fixing hole 412 opening into the output flow channel 43. A flow sensor 01 and / or a temperature sensor are installed in the fixing hole 412. The flow sensor 01 and / or the temperature sensor are electrically connected to the driver 30. In the embodiment provided by this utility model, a flow sensor 01 is installed in the fixing hole 412. However, depending on actual needs, a temperature sensor can also be installed at the same time, or only a temperature sensor can be installed in the fixing hole 412.

[0024] In this invention, a fixing hole 412 opening into the output flow channel 43 is provided in the pump base 40. A flow sensor 01 and / or a temperature sensor are installed in the fixing hole 412. The flow sensor 01 and / or temperature sensor are electrically connected to the driver 30, which in turn is electrically connected to the motor 10. The motor 10 drives the rotating shaft 20 to rotate, thereby driving the centrifugal pump body 50 to operate and pump water into the output flow channel 43. When the water flows through the output flow channel 43, the flow sensor 01 can detect the water flow rate, and the temperature sensor can detect the water temperature. The flow rate and water temperature are fed back to the driver 30, which controls the speed of the motor 10 accordingly, flexibly adapting to production needs. In addition, the driver 30 is mounted on the top of the motor 10, and the driver 30 controls the speed, power, etc. of the motor 10, making the structure more compact. Preferably, the motor 10 is a three-phase AC permanent magnet motor.

[0025] like Figures 1 to 5 As shown, the output channel 43 includes a first channel portion 431 disposed within the pump base 40 and a second channel portion 432 disposed within the output connector 42, with the fixing hole 412 opening into the first channel portion 431. Furthermore, the second channel portion 432 is formed with a threaded structure for connecting to a water pipe, so that the output connector 42 can be connected to the water pipe more stably.

[0026] like Figures 1 to 5 As shown, the outer side of the driver 30 is a circular side. The four sides of the driver 30 are located within the space defined by the outer side of the motor 10, so that the four sides of the driver 30 do not extend beyond the motor 10, making the structure more compact and easier to arrange.

[0027] like Figures 1 to 5 As shown, the output channel 43 extends to the bottom of the base 41 and is arranged in a bent manner. The outer side wall of the end of the output connector 42 is provided with a chamfer 421, which facilitates the insertion of the water pipe into the output channel 43 of the output connector 42.

[0028] like Figures 1 to 5 As shown, the base 41 includes an upper base structure 413, a middle base structure 414, and a lower base structure 415 connected sequentially from top to bottom. The upper base structure 413 and the lower base structure 415 are hollowed out, with a mounting through hole 411 penetrating from top to bottom through them. Hollowing out the upper base structure 413 and the lower base structure 415 effectively reduces the overall weight of the base 41, making the device more portable. Preferably, the base 41 is made of metal, such as a metal casting, but it can also be made of plastic depending on the actual needs.

[0029] like Figures 1 to 5As shown, the upper base structure 413 is connected to the middle base structure 414 through several upper connecting bodies 416. The upper base structure 413 and the middle base structure 414 enclose an upper structure space. The upper connecting bodies 416 are spaced apart and form an upper structure space between them. The upper connecting bodies 416 are spaced apart and form an upper structure gap 401 that communicates with the upper structure space between them. The upper structure space and the upper structure gap 401 allow the upper base structure 413 to be hollowed out. The upper base structure 413 is roughly disc-shaped, but not limited to this.

[0030] like Figures 1 to 5 As shown, the middle base structure 414 is connected by several lower connecting bodies 417, and the middle base structure 414 and the lower base structure 415 enclose a lower structure space. The lower connecting bodies 417 are arranged at intervals and form a lower structure gap 402 that communicates with the lower structure space between them.

[0031] The following is a brief description of the working process of the AC permanent magnet machine tool water pump 100 of this utility model: The motor 10 drives the rotating shaft 20 to rotate, and the rotation of the rotating shaft 20 drives the centrifugal pump body 50 to operate. Water is pumped in stages, and the energy increases continuously, resulting in a higher head. The pumped water flows into the output channel 43 and is finally pumped to the water pipe for output.

[0032] The above-disclosed examples are merely preferred embodiments of the present utility model and should not be construed as limiting the scope of the present utility model. Therefore, any equivalent variations made in accordance with the claims of the present utility model shall fall within the scope of the present utility model.
