Description
Technical field
the present invention 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: when drive force plunger is reciprocating in cylinder body plunger hole, the airtight work cavity volume generation volume-variation that plunger and cylinder body are formed, thereby realize oil suction, oil extraction process, it is high that plunger pump has rated pressure, compact structure, the advantage such as efficiency is high and Flow-rate adjustment 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, when rotor is done 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; When 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 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.When transmission shaft drives oil cylinder rotation, under the effect of low pressure food tray, plunger is just done linear reciprocating motion in oil cylinder, when plunger stretches out from oil cylinder, through oil distribution casing, suck low pressure oil, when 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, pressure oil output constantly just.
yet, no matter be radial plunger pump or axial piston pump, its structure is more complicated all, takes up room larger, and cost of production is also higher.

wherein: 1, electromagnetic actuator device; 11, electromagnetic coil; 12, iron core; 2, plunger assembly; 21, assembly department; 22, plug; 23, permanent magnet; 3, cylinder body; 4, fuel tank; 5, the first one-way valve; 6, the second one-way valve.
Embodiment
below in conjunction with accompanying drawing and specific embodiment, technological scheme of the present invention is further elaborated.
referring to the electromagnetic plunge pump shown in Fig. 1, Fig. 2, be located on support.This plunger pump comprises plunger case, this plunger case comprise the cylinder body 3 that is installed on support, can be along the plunger assembly 2 of self being located at axially slidably on support, this plunger assembly comprises plunger and is installed in the permanent magnet 23 of plunger one end, the other end of this plunger be snugly located in cylinder body 3 and relatively cylinder body 3 slide vertically.Here, plunger comprises assembly department 21 and the plug 22 of being located at assembly department 21 one end, and assembly department 21 can one-body moldedly arrange with plug 22, also after separable setting, is fixed together again.The inner chamber aperture of the diameter of plug 22 and cylinder body 3 matches, and plug 22 is snugly located in cylinder body 3 and cylinder body 3 setting slidably vertically relatively.Assembly department 21 is slidably disposed on support, on assembly department 21, offers open recess, and wherein the opening of open recess is positioned at the axle head of assembly department 21, and permanent magnet 23 is housed in this open recess.
this electromagnetic plunge pump also comprises for drive plunger assembly 2 along himself electromagnetic actuator device 1 in axial sliding, and this electromagnetic actuator device 1 comprises the electromagnetic coil 11 that is installed on support, is located in the iron core 12 in electromagnetic coil 11 regularly.Plunger assembly 2 is located at a side of electromagnetic actuator device 1, the adjacent setting in one end of permanent magnet 23 and iron core 12 on plunger assembly 2, and the shaft axis of the shaft axis of plunger assembly 2 and iron core 12 distributes along same rectilinear direction.When electromagnetic coil 11 passes into electric current, on iron core 12, can obtain magnetic, by changing sense of current, can change the magnetic at iron core 12 two ends.
the Magnetic Phase different time between iron core 12 and permanent magnet 23, between permanent magnet 23 and iron core 12, produce attraction force and attract each other, plunger assembly 2 moves towards iron core 12, volume in cylinder body 3 increases gradually, under the effect of pressure, hydraulic oil in fuel tank 4 enters in cylinder body 3 through the first one-way valve 5, i.e. cylinder body 3 oil suctions; Magnetic Phase between iron core 12 and permanent magnet 23 simultaneously, between permanent magnet 23 and iron core 12, produce repulsion, plunger assembly 2 moves away from iron core 12, and the volume in cylinder body 3 reduces gradually, and the hydraulic oil in cylinder body 3 is extruded and enters in system pipeline to be entered through the second one-way valve 6.
for improving the mechanical efficiency of this electromagnetic plunge pump, in the present embodiment, plunger case has two, and two above-mentioned plunger cases are located at the both sides of iron core 12 symmetrically, and the magnetic pole that closes on the end of iron core 12 in two plunger cases on permanent magnet 23 arranges on the contrary.
for example, in Fig. 1, Fig. 2, if in the plunger case in left side, the end that permanent magnet 23 closes on iron core 12 is the N utmost point, and, in the plunger case of right side, the end that permanent magnet 23 closes on iron core 12 just should be set to the S utmost point.Like this, when electromagnetic coil 11 energising, if the left side of iron core 12 is the S utmost point, its right side is the N utmost point, like this, the permanent magnet 23 of both sides all and between iron core 12, produce attraction force and gradually with iron core 12 magnetic attractions, the plunger assembly 2 of both sides all slides away from cylinder body 3, in the cylinder body 3 of both sides, volume all increases gradually and carries out oil suction work; When electromagnetic coil 11 passes into back current, the left side of iron core 12 is the N utmost point, and its right side is the S utmost point, like this.Between the permanent magnet 23 of iron core 12 and both sides, all produce repulsion, the plunger assembly 2 that this repulsion makes both sides all slides towards cylinder body 3, and the volume in the cylinder body 3 of both sides reduces and gradually to system pipeline fuel feeding to be entered.
to sum up, electromagnetic plunge pump of the present invention, wherein utilize electromagnetic force to carry out the plunger assembly 2 of drive post plug cylinder, make relative cylinder body 3 to-and-fro motion of plunger assembly 2 and realize the continuous oil suction of this plunger pump and the process of fuel feeding, it is simple in structure, take up room little, cost of production is lower, and has higher efficiency of energy utilization.
above-described embodiment is only explanation technical conceive of the present invention and feature, and its object is to allow person skilled in the art can understand content of the present invention and implement according to this, can not limit the scope of the invention with this.All equivalences that Spirit Essence is done according to the present invention change or modify, within all should being encompassed in protection scope of the present invention.
