Embodiment approach

[0028] As an embodiment of the present invention, a plurality of horizontally arranged second chambers 15 are provided on the side wall of the first chamber 12, and second pistons 17 are correspondingly arranged in the second chambers 15. The piston 17 is fixedly provided with a second rod 16 toward the side of the first chamber 12; the lower part of the first piston 13 is in the shape of a truncated cone with a large upper part and a smaller lower part, and the second rod 16 extends into the first chamber 12 and is connected to the first chamber 12. The side wall of the bottom of a piston 13 interferes; the rodless chamber side of the second chamber 15 is provided with a second spring 18 which is resisted with the second piston 17, and the rodless chamber is provided with a The first air hole 8 communicating with the outside world. Through the setting of the second rod 16, when the first rod 10 is pressed down to drive the first piston 13 to move down, since the lower part of...

Abstract

The invention relates to the technical field of variable frequency motors, specifically a permanent magnet variable frequency motor for pumps, including a motor body and a shock absorber. The lower end of the motor body is fixedly provided with mounting feet, and the mounting feet are connected to the shock absorber by bolts. The upper end is detachably connected; the shock absorbing device includes a top plate, a shock absorbing block and a bottom plate arranged sequentially from top to bottom, and the mounting feet are detachably connected to the top plate through bolts; there are multiple A set of first springs, the first springs are arranged along the edge of the upper end of the shock absorber, and the lower end of the top plate is fixedly provided with a vertically arranged guide post; the setting of the first spring, the first piston, and the second piston can offset the motor body The impact force generated during work consumes the impact capacity, reduces the vibration intensity of the motor body, and reduces noise at the same time. The shock absorption effect is very good, and the stability of the motor body is improved.

Description

technical field [0001] The invention relates to the technical field of variable frequency motors, in particular to a permanent magnet variable frequency motor for pumps. Background technique [0002] A water pump is a machine that transports or pressurizes a liquid. It transmits the mechanical energy of the prime mover or other external energy to the liquid to increase the energy of the liquid. It is mainly used to transport liquids including water, oil, acid and alkali, emulsions, and suspoemulsions. And liquid metal, etc., can also transport liquid, gas mixture and liquid containing suspended solids; water pumps can be divided into volumetric water pumps, vane pumps and other types according to different working principles. , the vane pump uses the interaction between the rotating vane and water to transfer energy, and there are centrifugal pumps, axial flow pumps and mixed flow pumps. [0003] Existing water pumps are generally driven by permanent magnet variable frequen...
