Description
Technical field
the utility model relates to a kind of electromagnetic plunge pump.
Background technique
at present in oil hydraulic pump, plunger pump is widely applied with its simple working principle, its principle is: in the time that drive force plunger is reciprocating in cylinder body plunger hole, make the airtight work cavity volume generation volume-variation of plunger and cylinder body composition, thereby realize oil suction, oil extraction process, the advantages such as it is high that plunger pump has rated pressure, and the high and Flow-rate adjustment of compact structure, efficiency is convenient.Therefore, plunger pump is very extensive in the application of industrial field, and particularly, at high pressure and ultrahigh-pressure hydraulic transmission field, plunger pump is in occupation of the status can not be substituted.Plunger pump is the different spread patterns in cylinder body according to plunger, can be divided into radial and axial type.
the plunger radial of radial plunger pump is arranged and is arranged in cylinder body, cylinder body is by prime mover driven rotary, so cylinder body is commonly referred to as rotor, plunger is close to stator inner wall by the effect of centrifugal force or low pressure oil, in the time that rotor does clockwise reversed turning, owing to having throw of eccentric between rotor and stator, it is protruding when plunger passes through upper half, swept volume increases gradually in oil cylinder, forming section vacuum, therefore just the oilhole on lining from the inlet port oil suction of oil distributing shaft; In the time going to lower half, stator inner wall pushes back plunger, and in-oil cylinder working oil chamber diminishes gradually, hydraulic oil is flowed out to the force feed mouth of oil distributing shaft, and rotor returns and circles, and the each oil suction of each oil cylinder, force feed are once, rotor constantly rotates, and just can complete continuously oil transportation work.
the plunger of axial piston pump is arranged in cylinder body and is along the circumferential direction uniformly distributed, cylinder body is by transmission shaft driven rotary, the oil sucking window of the fluid of being supplied with by low pressure fuel pump on oil distribution casing enters oil cylinder, and one end of plunger is close on swash plate, and oil distribution casing and swash plate all maintain static.In the time that transmission shaft drives oil cylinder rotation, under the effect of low pressure food tray, plunger just does linear reciprocating motion in oil cylinder, in the time that plunger stretches out from oil cylinder, suck low pressure oil through oil distribution casing, in the time that plunger is compressed into oil cylinder by swash plate, the force feed window output high pressure oil on oil distribution casing, cylinder body often circles, each plunger back and forth movement once, complete oil suction oil extraction process one time, as transmission shaft drives cylinder body continuous operation, just pressure oil output constantly.
but, no matter be radial plunger pump or axial piston pump, all more complicated of its structure, take up room larger, and cost of production is also higher.
