Abstract

The invention discloses a power transmission device of a high-pressure magnetic pump, which belongs to the technical field of liquid delivery pumps. The power transmission device comprises a power transmission buffer shaft (49) and a supporting box (48), wherein the supporting box (48) is arranged on a base (42); and one end of the power transmission buffer shaft (49) is connected with a main shaft of a motor (47), and the other end of the power transmission buffer shaft (49) is connected with a first-stage transmission shaft (36). Compared with the prior art, the power transmission device has the advantage that the power transmission device has a simple structure and is reliable in performance, equipment is high in intensity, stability and safety, and the like.

Description

technical field [0001] The invention belongs to the technical field of liquid conveying pumps, and more specifically, belongs to a power transmission device of a high-pressure magnetic pump. Background technique [0002] The existing conventional magnetic pump adopts a common magnetic seal device structure, and the common magnetic seal includes an inner rotor body, an outer rotor body, and a spacer sleeve. The isolation sleeve seals and separates the inner and outer rotor bodies completely. When the pump is running, the medium in the isolation sleeve completely submerges the inner rotor body, and there must be internal pressure inside. This internal pressure is equal to the pressure of the pumped medium. The isolation sleeve must be very To achieve a good sealing effect, it must be able to withstand the internal pressure of the pumped medium to ensure that the isolation sleeve is not deformed or damaged. Since the air gap between the inner and outer magnetic rotor bodies wi...
