Embodiment Construction

[0015] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments, but the protection scope of the present invention is not limited thereto.

[0016] like figure 1 As shown, the motor-pump integrated miniature high-speed magnetic pump of the present invention includes a pump casing 1, an impeller 2, a motor casing 3, a stator winding 4, a spacer 10, a motor cover plate 6, a drive circuit board 8, a magnetic rotor, permanent magnet 7. The outer peripheral surface of the rear cover of the impeller 2 has an annular groove, and the permanent magnet 7 is fixed in the annular groove. The impeller 2 and the permanent magnet 7 embedded on the back cover of the impeller 2 form a magnetic rotor. The axis position of the rear cover of the impeller 2 has a groove; the spacer 10 is in the shape of a "bow" and has a protrusion that can be embedded into the rear cover of the impeller 2, and the protrusion is embedded behind ...

Abstract

The invention provides a motor-pump-integrated micro high-speed magnetic pump which comprises a pump shell, an impeller, a motor shell, a stator winding, a spacer bushing, a motor cover plate, a driving circuit board, a magnetic rotor and a permanent magnet. An annular groove is formed in the outer surface of a rear cover plate of the impeller, the permanent magnet is fixed in the annular groove, axis position of the rear cover plate of the impeller is fixedly connected with the spacer bushing, the space bushing, the motor shell and the motor cover plate form a closed space, the stator winding and the driving circuit board are positioned in the closed space, the stator winding surrounds the permanent magnet by one circle, the back of the pump shell is provided with a connecting portion connected with the motor shell, and the motor shell is fixed on the connecting portion. The pump shell integrates a pump cover plate and a connecting device connected with a motor, and a static component of the motor is connected with the pump shell; the permanent magnet of the impeller forms the magnetic rotor of the motor, so that transmission parts are reduced, size and weight of the micro magnetic pump are reduced, and motor-pump integration is realized.

Description

technical field [0001] The invention relates to a magnetic force pump, in particular to a miniature high-speed magnetic force pump integrated with a machine and a pump, which is used in the field of spaceflight, aviation and the like to transport trace liquids. Background technique [0002] The high-speed magnetic pump has the characteristics of small flow, high lift and no leakage. After the speed is increased, not only can the volume and weight of the pump be effectively reduced, but also the efficiency of the pump can be improved. High-speed magnetic pumps are mainly used in aviation, aerospace, petrochemical and other important fields. Existing high-speed magnetic pumps often adopt separate structure of AC motor and pump. The motor and pump each have independent rotors, and the motor rotor and pump rotor are connected by a magnetic coupling to realize torque transmission. With the upgrading of overall technology in aerospace, aviation and other fields, magnetic pumps a...
