Pressure adjustable reciprocating synchronization alternating current and direct current electromagnetic pump

Abstract

The invention relates to a pressure adjustable reciprocating synchronization alternating current and direct current electromagnetic pump. According to the technical scheme of the invention, the electromagnetic pump comprises a pump body, a pipeline portion and a control portion, wherein the pump body is of a cylindrical and hollow structure. A first electromagnetic column and a second electromagnetic column, arranged in symmetry and right opposite to each other, are fixed to the two ends of the pump body. An electromagnetic plug cylinder sliding in the length direction of an inner cavity of the pump body is arranged in the pump body and located between the first electromagnetic column and the second electromagnetic column. The pipeline portion comprises a first suction pipe, a second suction pipe, a first exhaust pipe and a second exhaust pipe. The first suction pipe and the second suction pipe intersect at a fluid inlet while the first exhaust pipe and the second exhaust pipe intersect at a fluid outlet. The control portion comprises a controller, a double pole double throw electromagnetic relay and a pressure sensor. The pressure adjustable reciprocating synchronization alternating current and direct current electromagnetic pump is efficient and saves energy, the output pressure can be adjusted automatically, and both alternating current and direct current can be used. Common problems, bothering fluid conveying equipment, such as idling, air bind and gas etching need not to be considered, the safe fluid conveying can be achieved, operation is simple, and the service life is long.

Description

technical field [0001] The invention relates to an electromagnetic pump, in particular to a reciprocating synchronous AC and DC electromagnetic pump with adjustable pressure. Background technique [0002] Electromagnetic pump is a power pump used to transport corrosive, dangerous liquid or liquid metal in chemical industry, printing and dyeing industry. It generates magnetic field through electromagnetic coil, and uses electromagnetic force to make the piston move in the pump body, thereby generating driving force, so that fluid flow. Electromagnetic pumps usually include pump body, rotor, stator and lines. Conventional electromagnetic pumps often use half-width push in order to match the rotor and stator poles, that is, two round trips in one working cycle of the piston, one push and one suction, which makes the continuity of fluid delivery worse and increases the pump efficiency. The discount brings great difficulty and cost to the installation, use and operation of the ...

AI Technical Summary

Problems solved by technology

Conventional electromagnetic pumps often use half-width push in order to match the rotor and stator poles, that is, two round trips in one working cycle of the piston, one push and one suction, which makes the continuity of fluid delivery worse and increases the pump efficiency. The discount brings great difficulty and cost to the installation, use and operation of the electromagnetic pump, and also causes a lot of energy loss

Moreover, the traditional delivery pumps have fixed heads and flow rates, and cannot set or adjust delivery parameters according to actual working conditions, nor can they adjust themselves according to changes in fluid flow conditions in the actual working environment, resulting in large pressure fluctuations or idling, which brings great harm to the project. Brings a lot of difficulties and waste of energy in the application

In addition, mechanical pumps often produce air binding or cavitation due to flow changes, causing damage to the pump body or even accidents. Therefore, the existing technology is in urgent need of improvement and development
