AI Technical Summary

Technical Problem

In the prior art, the reciprocating movement of the working diaphragm depends on the direct connection of the mechanical structure, which leads to friction and wear, affects service life, increases operating costs, and the mechanical transmission system generates high noise, and only one side of the working diaphragm is subjected to pressure, which is easy to Causes to remove or explode the membrane.

Method used

Adopt a high -voltage magnetic pump structure. Through the magnetic transmission parts, the magnetic driving operating film is used to re -move, reducing the direct connection between the mechanical structure and the working film, and increasing the balance pipeline to lead the drainage cavity to the back of the working film to achieve both sides of the two sides. Stress balance.

Benefits of technology

Reduce the wear of the working film, improve the service life and reliability of the equipment, reduce noise, enhance the sealing, and improve the ability of the working film to withstand pressure.

Abstract

The invention belongs to the field of output pumps, and particularly relates to a high-pressure magnetic drive pump structure which comprises a transmission shell provided with a liquid suction cavity, a liquid drainage cavity and a driving cavity. The balance pipeline is mounted on the transmission shell; the magnetic transmission component is mounted on the transmission shell; and a plurality of working diaphragms, wherein the working diaphragms are arranged on the transmission shell. The magnetic transmission component drives the working diaphragm to reciprocate by utilizing magnetic force, so that excessive abrasion to the working diaphragm caused by direct connection of a mechanical structure and the working diaphragm is reduced, the service life of equipment is prolonged, the reliability of the equipment is improved, after the working diaphragm is extruded, pressure is generated on the front side of the working diaphragm, and the diaphragm is easy to explode when the pressure is too large. At the moment, the liquid discharging cavity is communicated with the back face of the working diaphragm through the balance pipeline, the same pressure can be generated on the back face of the working diaphragm, and after the pressure of the liquid discharging cavity and the pressure of the working diaphragm are offset, the bearing pressure of the working diaphragm is improved.
