Description

Electromagnetic pump

Technical field

The utility model relates to a kind of reciprocating pump that is used for the transmitting fluid medium, especially relates to a kind of shuttle electromagnetic pump.

Background technique

The reciprocating pump of tradition conveyance fluid medium all needs motor as power source, and reciprocating to finish the conveying of flowing medium by piston or plunger in the drive part drive pump housing.But because the reciprocating pump of this structure is made of the pump housing part of power section, drive part and execution etc., make reciprocating pump bulky, complex structure, functional reliability is poor, energy consumption height not only, and also maintenance load is big.For overcoming above-mentioned defective, existing a kind ofly come driven plunger or the reciprocating electromagnetic pump of plunger to realize that flowing medium is carried by electromagnetic force.But a kind of structure of present disclosed electromagnetic pump mainly is made of support, the electromagnetic core and the coil winding that are connected the pump housing on the support and are connected pump housing both sides, electromagnetic core and coil winding are arranged in the protective housing, after left and right two groups of coils are switched on respectively, produce electromagnetic force and make the plunger in the pump housing reciprocating, the flowing medium in the active chamber of pump housing both sides is sucked and sends.Though this kind electromagnetic pump and tradition by the reciprocating pump of driven by motor mutually specific volume reduce greatly, cancel drive part and make the electromagnetic pump structure simple relatively, but the pump housing is axially to be connected with coil winding with two groups of electromagnetic cores by adpting flange, so whole electromagnetism pump structure is not compact, volume is relatively large, because of making is had relatively high expectations and increased cost.Another kind of disclosed electromagnetic pump, electromagnetic core and coil winding are set on the pump housing, producing alternating magnetic field behind coil electricity makes plunger reciprocating, flowing medium in the active chamber of pump housing both sides is sucked and sends, though this electromagnetic pump is simple in structure, plunger relies on liquid stream buffering, so operation vibration and noise are bigger, shortened the working life of electromagnetic pump, and flow quantity is little.

Summary of the invention

The purpose of this utility model provides a kind of compact structure, and volume is little, reliable operation, the electromagnetic pump of long service life.

The utility model is that the technological scheme that achieves the above object is: a kind of electromagnetic pump, comprise coil winding, electromagnetic core, in be provided with the liquid inlet joint and the fluid joint of one-way valve, it is characterized in that: described coil winding and electromagnetic core are encapsulated in the insulation shell; The axis hole that is contained in its outside of axle sleeve in coil winding and the electromagnetic core is tightly connected by nozzle and liquid inlet joint, one-way valve and nozzle in the liquid inlet joint join, and the soft pad that has the liquid hole is housed in the nozzle, and the axis hole of axle sleeve inboard is connected with the fluid joint sealing; The plunger of making axially reciprocating is housed in the axle sleeve, its valve seat of one-way valve that withstands on the inboard liquid mouth of plunger place links to each other with plunger, be provided with spring between valve seat and the fluid joint cavity interior edge face, be provided with spring between the internal projecting ring end face of the distolateral and axle sleeve of the shaft shoulder of plunger, the inner side end of fluid joint is equipped with buffer gasket.

The utility model adopts the advantage after the technique scheme to be: the first, electromagnetic pump of the present utility model is by being installed in the axle sleeve in coil winding and the electromagnetic core, and the two side ends liquid inlet joint and the fluid joint that are connected axle sleeve connect and compose, simplified the linkage structure of electromagnetic pump, under the effect of the elastic force of the energy-storaging spring of generation electromagnetic force and plunger both sides behind the coil electricity, make plunger in axle sleeve, make axially reciprocating, fluid medium is carried, flow quantity is big, compact structure, reasonable, improve functional reliability, but also be convenient to maintenance.The second, coil winding of the present utility model, electromagnetic core, axle sleeve and plunger are coaxial installations, and coil winding, electromagnetic core are again to be encapsulated in the insulation shell, therefore the volume of electromagnetic pump further reduces, and is particularly suitable for the conveying of high temperature, high-pressure fluid medium.Three, be equipped with one-way valve in the liquid inlet joint of the present utility model and in the plunger, good seal performance, compact structure not only, and in the course of conveying of fluid, fed sheet of a media continuously, fluid homogeneous media.Four, the utility model not only is equipped with spring in the both sides of plunger, and the both side ends of plunger also is provided with soft pad and buffer gasket, therefore the noise that the shock and vibration that produce in the time of working to electromagnetic pump preferably produce cushions further and absorbs, and prolongs the working life of electromagnetic pump.
