Electromagnetic pump capable of adjusting flow range

Abstract

The invention discloses an electromagnetic pump capable of adjusting a flow range. The electromagnetic pump comprises a pump shell. A pipe body is arranged in the pump shell. An electromagnetic assembly is arranged on the inner wall of the pipe body. A bearing is arranged in the pipe body. A return spring is arranged at the bottom of the bearing. A pipe body through groove is formed in the bottomend of the pipe body. The bearing and the groove wall of the pipe body through groove define a first flow channel. The interior of the pump shell and the groove wall of the pipe body through groove define a second flow channel. A sealing cavity is formed in the pump shell. A piston cavity and an axial valve port are formed in two ends of the sealing cavity. An output end is arranged at one end ofthe pump shell. An output hole is formed in the output end. A first one-way valve device is arranged in the sealing cavity, and a second one-way valve device is arranged in the output hole. A lower limit value of a flow adjusting range of the electromagnetic pump is reduced, working efficiency is improved, mounting and dismounting are facilitated, and later maintenance is facilitated.

Description

technical field [0001] The invention relates to the technical field of electromagnetic pump design, in particular to an electromagnetic pump with an adjustable flow range. Background technique [0002] Electromagnetic pump is a pump in which the current-carrying fluid in the magnetic field flows in a certain direction under the action of electromagnetic force. The electromagnetic pump is a device that uses the interaction between the magnetic field and the current in the conductive fluid to cause the fluid to generate a pressure gradient under the action of electromagnetic force, thereby pushing the fluid to move. Electromagnetic pumps have the characteristics of compact structure, high output pressure, relatively low price, and good dynamic adjustment characteristics. The flow rate of the liquid delivered by the existing electromagnetic pumps is limited by regulation, and the processing technology is limited at the same time. The cost is high and the work efficiency is low....
