An electromagnetic diaphragm quantitative pump

Abstract

The invention belongs to the technical field of metering pumps and particularly relates to an electromagnetic diaphragm metering pump. The pump comprises a pump body, a diaphragm, a pump cavity, a metal filter net, a discharging pump head, a first ball, a feeding pump head, a second ball, a threaded column, a worm wheel, a screw barrel, a worm, a mounting plate, barrels, column bodies, a bottom plate, a base, a piston, a piston cavity, an electromagnetic push rod, a piston column and worm mounting plates. The electromagnetic diaphragm metering pump is simple in structure and convenient to maintain and use, the metal filter net is mounted on the pump, particles in liquid materials can be effectively prevented from making contact with the diaphragm, the probability of damage of the diaphragmis greatly reduced, and the service life of the pump can be guaranteed easily; and a height adjusting mechanism is contained in the pump, when the pump is mounted and used, the height of the pump canbe adjusted through the height adjusting mechanism, no gasket is needed, accordingly, the feeding pump head of the pump can be connected with an output end of an external storage device conveniently,and using of the pump is greatly facilitated.

Description

technical field [0001] The invention belongs to the technical field of quantitative pumps, in particular to an electromagnetic diaphragm quantitative pump. Background technique [0002] Electromagnetic diaphragm quantitative pump is a quantitative pump structure driven by electromagnetic, mainly composed of electromagnetic coil, iron stopper, spring, moving iron, diaphragm, pump seat, pump body, cover plate and other parts. When the electromagnetic coil is energized, the electromagnetic force will move The iron and the retaining iron are attracted together, the spring is compressed, the moving iron drives the diaphragm connected to it to move downward, the volume between the diaphragm and the pump body increases, and the liquid is sucked in from the liquid inlet. When the electromagnetic coil is powered off, the spring Under the action of the elastic force, the moving iron and the diaphragm are pushed upward, the volume between the diaphragm and the pump body decreases, and ...

AI Technical Summary

Problems solved by technology

[0003] The structure of the existing electromagnetic diaphragm quantitative pump is relatively complicated, which is not convenient for maintenance and use, and most of the pump body does not contain a filter screen, and the particles in the liquid material are easy to damage the diaphragm, which is not conducive to ensuring the service life of the quantitative pump. At the same time, the existing Most electromagnetic diaphragm quantitative pumps do not contain a height adjustment mechanism. When in use, it is often necessary to place a gasket on the bottom of the quantitative pump to facilitate the connection with the output end of the external storage device. This is inconvenient and has certain shortcomings.
