Description

Reciprocating electromagnetic liquid pump

The utility model belongs to the pump class, is a kind of reciprocating electromagnetism liquid pump.

It is reported that the working power circuit of its electromagnet of electromagnetism liquid pump that the actual at present still retrieval of using is found is all complicated, thereby the cost of pump is also high, is exactly an example as the described electromagnetism liquid pump of B. P. GB2087657.

The purpose of this utility model is that a kind of work of electromagnet circuit is simple, cost is low, efficient is high in order to provide, the reciprocating electromagnetism liquid pump of saving electric energy.

Reciprocating electromagnetic liquid pump provided by the utility model can be divided into single pump and group's pump.

Single pump is made up of critical pieces such as the pump housing, the end cap that has the liquid in-out mouth, piston, piston sleeve, one-way valve, electromagnet, and the working power circuit of electromagnet is the half-wave rectifying circuit that single phase poaer supply, switch, transformer (also shouldn't transformer), diode, capacitor be formed.Sort circuit makes in the field coil of electromagnet only by unidirectional pulsating current, produces the certain electromagnetic force of direction thereby be interrupted, and this electromagnetic force and the piston reset spring power promotion piston reciprocates of working in coordination is to finish the task of conveying liquid.

Group's pump is formed plural single pump (removing the end cap of single pump) connection by the upper and lower end cap that has the liquid in-out mouth, and disposed the inner cap of band one-way valve at the outlet end of each single pump, so that do not interfere with each other between each single pump during group's pump work, can increase the flow and the lift of group pump like this.Working power or the single phase poaer supply or three phase mains (the available transformer step-down of group's pump electromagnet, also can be) without the transformer step-down, its circuit is several group half-wave rectifying circuits identical with single pump quantity, all has only a diode, a capacitor in every group of half-wave rectifying circuit.This working circuit of group's pump electromagnet had both utilized the positive half-wave voltage of power supply, had utilized the negative half-wave voltage of power supply again, thereby had improved the utilization ratio of electric energy.

Electromagnetism liquid pump provided by the utility model, the material of its piston sleeve are bronze or high-pressure glass.

Electromagnetism liquid pump provided by the utility model, the big I of its flow, pressure, lift is controlled by the diameter that changes electromagnet and piston.Therefore, it can be widely used for liquid transportation art such as machine tool lubrication, cooling and deep-well water lift.

This kind electromagnetic pump has the following advantages:

1. working circuit is simple, and is convenient to maintenance;
