Double-head diaphragm pump with mirror symmetry

Abstract

The invention provides a double-head diaphragm pump with mirror symmetry. The defects in the prior art are overcome, a liquid inlet channel and a liquid outlet channel are completely separated throughthe structural design, the problem of liquid leakage is effectively solved, and the service life of the diaphragm pump is prolonged by improving the structural strength of a shell. A motor is vertically arranged in the middle of the upper side of the shell, end covers are fixedly arranged at the two ends of the shell, the power output end of the motor extends downwards into the shell, a cam sleeves the power output end of the motor, a partition plate sleeves the middle of the cam, a sleeve ring sleeves the cam on the two sides of the partition plate, and two swing rods are symmetrically arranged in the shell. One end of the each swing rod is connected to the sleeve rings on the two sides of the partition plate respectively, diaphragm plates are arranged at the other ends of the two swingrods respectively, grooves are formed in the outer sides of the diaphragm plates, diaphragm pads are fixed in the grooves of the diaphragm plates through screws, and the outer side faces of the diaphragm pads protrude out of the outer side faces of the diaphragm plates.

Description

technical field [0001] The invention discloses a mirror symmetrical double-head diaphragm pump, which belongs to the technical field of diaphragm pumps. Background technique [0002] During the working process of the existing diaphragm pump, the inlet and outlet of the end cover are completely separated by the gasket, the liquid is prone to leakage, the inlet and outlet of the inverted diaphragm pump are damaged, and even leakage accidents occur, damaging the diaphragm pump and greatly reducing The service life of the diaphragm pump is shortened, and the diaphragm pump will vibrate intermittently during use. Long-term use can easily cause the structural connection of the pump body to loosen, resulting in cracking and damage to the shell and reducing the service life of the diaphragm pump. Contents of the invention [0003] The present invention overcomes the deficiencies in the prior art and provides a mirror-symmetrical double-head diaphragm pump. Through structural desig...

AI Technical Summary

Problems solved by technology

[0002] During the working process of the existing diaphragm pump, the inlet and outlet of the end cover are completely separated by the sealing gasket, and the liquid is prone to leakage. The service life of the diaphragm pump is shortened, and the diaphragm pump will vibrate intermittently during use. Long-term use can easily cause the structural connection of the pump body to loosen, resulting in cracking and damage to the shell and reducing the service life of the diaphragm pump.
