A kind of electromagnetic reciprocating pump
Technical field
The present invention relates to pump technology, specifically a kind of compact conformation, easy for installation, Flow-rate adjustment facilitate, use the longevity Life is long, noiseless electromagnetic reciprocating pump.
Background technology
It is well known that generally for aspirating, convey liquid(Gas)Body and make liquid(Gas)Body increases stressed machine and is referred to as Pump.From for energy viewpoint, pump is a kind of machine for changing energy, and it is converted into the mechanical energy of prime mover by conveying liquid(Gas) The energy of body, makes liquid(Gas)The flow velocity and pressure of body increase, pump as a kind of universal machine, in national economy every field all It is widely used, the species of pump is a lot, can be classified by its operation principle, feature and purposes, by its operation principle Vane type oil pump, positive displacement pump and other types pump can be divided into, positive displacement pump therein is divided into reciprocating pump and drum pump again.
The critical piece of the structure of reciprocating pump includes:Pumping cylinder, piston, piston rod, inlet valve and dump valve, operation principle It is that piston is driven by electronic toggle, the rotary motion of crank is changed into the reciprocating motion of piston;Or directly by Steam engine drives, and piston is moved reciprocatingly;When piston is moved from right to left, low pressure is formed in pumping cylinder, dump valve is arranged Go out the pressure of liquid in pipe and close;Inlet valve is opened by the effect of low pressure in cylinder, and storage pot liquid is inhaled into cylinder; When piston is moved from left to right, because fluid pressure increases in cylinder, suction valve closure, dump valve is opened to exterior liquid, thus It can be seen that, reciprocating pump is directly to provide energy to liquid in the form of pressure energy by the reciprocating motion of piston, and this pump needs Input mechanical energy can just make its work, with volume it is big, inconvenient, work be installed have the deficiencies such as noise.
The content of the invention
Present invention aim to address above-mentioned the deficiencies in the prior art, there is provided a kind of compact conformation, easy for installation, flow are adjusted Section convenience, long service life, the noiseless electromagnetic reciprocating pump of work.
The technical solution adopted for the present invention to solve the technical problems is:
Inlet of the present invention and liquid outlet are respectively equipped with the both ends of pumping cylinder, are set on the permanent magnet of piston liquid feeding end The permanent magnet for having inlet opening, piston outlet end is provided with fluid hole, and valve ball chamber is provided with nonmagnetic piston shelf, and valve ball sets in chamber There is the non magnetic valve ball with diameter greater than inlet opening, valve ball can be moved in valve ball chamber along the line of inlet opening and fluid hole, feed liquor The line of mouth and liquid outlet typically coincides with piston axis, and the inlet opening inconsistent with valve ball and fluid hole are respectively equipped with and valve The close-fitting ball face of ball.
Non magnetic piston shelf of the present invention is respectively arranged at two ends with the Baltimore groove of mosaic magnet, and Baltimore groove is provided with and permanent magnetism The body inlet opening delivery hole corresponding with fluid hole, two Baltimore grooves form valve ball by least two pillar support connections, branch intercolumniation Chamber, is provided with valve ball in valve ball chamber, the Baltimore groove back side of outlet end is provided with valve ball obstruction boss, and valve ball obstruction boss is provided with and drain The corresponding valve ball obstruction hole in hole, valve ball obstruction boss is provided with intake chute, so that valve ball chamber connects with liquid outlet.
The pillar of two Baltimore grooves of support connection of the present invention is respectively equipped with through hole, and magnetic connecting rod, magnetic are provided with through hole Property connecting rod is connected through magnetic force with permanent magnet, to increase the connection reliability of two permanent magnets.
The axis of inlet of the present invention and liquid outlet coincides with the axis of pumping cylinder, inlet and liquid outlet be respectively equipped with The screw thread that feed tube is connected with drain pipe.
The present invention work when, magnet coil is connected through wire with power supply, magnet coil obtain it is electric after respectively in pumping cylinder The alternate N poles in two ends, S pole fields, at the same time, magnetic piston in cylinder sleeve according to homopolar-repulsion, the principle that there is a natural attraction between the sexes with The change in magnetic field and displacement back and forth, to carry out pump liquid, have the advantages that simple structure, small volume, easy for installation, noiselessness.
