Adjustable two-way acting electromagnetic diaphragm pump

Abstract

The invention relates to an adjustable two-way acting electromagnetic diaphragm pump. The adjustable two-way acting electromagnetic diaphragm pump comprises a valve body, wherein a hollow inner cavity is formed in the valve body; a diaphragm, wherein the diaphragm is arranged in the inner cavity of the valve body and divides the inner cavity into a first air chamber and a second air chamber; and an electromagnetic driving assembly, wherein the electromagnetic driving assembly is used for driving the diaphragm to move in the inner cavity to extrude the space of the first air chamber or the second air chamber, a first air inlet and a first air outlet which can be opened and closed are formed in the portion, located in the first air chamber, of the valve body, and a second air inlet and a second air outlet are formed in the portion, located in the second air chamber, of the valve body. The adjustable two-way acting electromagnetic diaphragm pump is small in size and convenient to carry; by utilizing the characteristic of magnetic air conduction, mechanical contact friction can be effectively reduced, abrasion is relieved, and maintenance cost is reduced; and when the electromagnetic driving assembly drives the diaphragm to extrude and expand in the space on one side, the closed working space on the other side is in an opposite state, and the operation is cycled, so that the working efficiency is doubled in the same operation period, the working efficiency of the diaphragm pump in unit time is effectively improved, and the service life of the diaphragm is effectively prolonged.

Description

technical field [0001] The invention belongs to the field of pumps, and relates to a diaphragm pump, in particular to an adjustable bidirectional work-acting electromagnetic diaphragm pump. Background technique [0002] Diaphragm pump is a kind of conveying machine, widely used in biology, chemistry, chemical industry and other disciplines, mainly used for the extraction of fluids such as gas and liquid. At present, there are many types and models of diaphragms on the market. Diaphragm pumps can be divided into solenoid valves, electronic types, intelligent types, and field bus type diaphragm pumps according to their functions and characteristics. For pneumatic transmission, mechanical transmission and hydraulic transmission, etc. The diaphragm pump is mainly driven by the crank connecting rod to reciprocate the diaphragm, but in the field of conveying gas, the traditional diaphragm pump can only do work once in one operation cycle, the efficiency is low, and the diaphragm ...

AI Technical Summary

Problems solved by technology

The diaphragm pump is mainly driven by the crank connecting rod to reciprocate the diaphragm, but in the field of conveying gas, the traditional diaphragm pump can only do work once in one operation cycle, the efficiency is low, and the diaphragm pump with large flow rate often fails due to the huge motor. Makes electric diaphragm pumps too heavy to be easily portable
