[0025] Embodiment 1:
[0026] As attached Figure 1 To Attachment Figure 6 As shown:
[0027] The utility model provides a high-efficiency water pump motor structure, including a support base 1; a lifting frame 101 is fixedly connected to the top position of the support base 1, a control frame 102 is fixedly connected to the upper rear end position of the lifting frame 101, the top position of the lifting frame 101 is matched with the bottom position of the mounting base 2, the mounting base 2 is designed in an I-shape, a magnetic-assisting synchronous reluctance motor 201 is installed at the front end position of the mounting base 2, a water pump part 203 is connected to the bottom position of the magnetic-assisting synchronous reluctance motor 201, a driver 202 is arranged at the front end position of the magnetic-assisting synchronous reluctance motor 201, the driver 202 itself is connected to the control module, the three-phase asynchronous motor of the original industrial water pump is replaced with the high-efficiency magnetic-assisting synchronous reluctance motor 201, and the frequency converter in the industrial water pump frequency conversion control cabinet is removed at the same time, and the industrial water pump is controlled by the driver 202, the driver 202 receives the start and stop commands sent by the DCS, changes the pump operation frequency by the frequency given value issued by the DCS, and transmits the real-time signal of the pump operation to the DCS.
[0028] The top middle position of the control frame 102 is rotatably connected to the bottom middle position of the screw rod 103 , and the screw rod 103 is rotatably connected to the threaded hole of the lifting member 104 , and the lifting member 104 is located directly above the control frame 102 .
[0029] Among them, the left and right sides of the control frame 102 are symmetrically connected to a transmission plate A105 for rotation, and the other ends of the two transmission plates A105 are respectively connected to a clamping arm 107 for rotation. The middle positions of the two clamping arms 107 are respectively located at the middle positions on both sides of the mounting seat 2 and are engaged, and the two clamping arms 107 are symmetrically designed.
[0030] The other ends of the two clamping arms 107 are rotatably connected to a transfer plate B106 respectively, and the other ends of the two transfer plates B106 are rotatably connected to the left and right sides of the lifting member 104 respectively.
[0031] When in use: first place the support base 1 to a suitable position, then place the bottom position of the mounting base 2 on the top position of the lifting frame 101, and then rotate the screw 103, and adjust the position of the lifting member 104 on the rod body of the screw 103 through the cooperation between the screw 103 and the threaded hole of the lifting member 104, so as to facilitate the adjustment of the distance between the lifting member 104 and the control frame 102.
[0032] When the distance between the lifting member 104 and the control frame 102 is close, the distance between the two clamping arms 107 will be moved away through the cooperation of the transfer plate A105 and the transfer plate B106. When the distance between the lifting member 104 and the control frame 102 is increased, the distance between the two clamping arms 107 will be moved closer through the cooperation of the transfer plate A105 and the transfer plate B106, so that the two clamping arms 107 can enter or leave the two side positions of the mounting seat 2, thereby facilitating the disassembly and maintenance of the mounting seat 2.

The overall loss is reduced by 20%-30% compared with the three-phase asynchronous motor, thereby increasing the service life of the equipment.
