Embodiment
The moving one plunger pump of the two-way control electric hand of this truck hydraulic system is stifled by oil connection A, oil connection B, selector valve A, pump cover, housing, manual plunger, depression bar frame, oil, relief valve, bearing, direct current generator, electric plunger and selector valve B form, the bottom of housing 5 has been bolted a direct current generator 11, on the axle of direct current generator 11, be fixed with bearing 10, the bolt that passes on left of housing 5 is equipped with pump cover 4, selector valve A3 and selector valve B13 are installed in pump cover 4, the left end of pump cover 4 is equipped with oil connection A1, and a side of pump cover 4 is equipped with oil connection B2.The right-hand member of pump cover 4 is placed in the left end of housing 5, the right-hand member of pump cover 4 is equipped with manual plunger 6, relief valve 9 and electric plunger 12 from top to bottom successively, manual plunger 6, relief valve 9 and electric plunger 12 pass through oil duct UNICOM with selector valve A3 and selector valve B13, and the right-hand member in housing 5 is fixed with a depression bar frame 7 by circlip.The right-hand member of housing 5 is threaded connection oil stifled 8 is housed.(referring to accompanying drawing 1～3)
The working procedure of the moving one plunger pump of the two-way control electric hand of this truck hydraulic system is as follows:
1, when plunger pump adopts electric model when work, direct current generator 11 energisings start to rotate, and band dynamic bearing 10 does eccentric rotary, then make electric plunger 12 overcome self spring resistance and do linear reciprocating motion.Because there is cavity electric plunger 12 inside, in the time that plunger does linear reciprocating motion, electric plunger 12 internal cavities volumes are followed the motion of plunger and change.In the time that plunger moves cavity volume and increases, produce suction, the resistance that makes the hydraulic medium of the seal space inside that pump cover 4 and housing 5 form overcome taper spring is pushed steel ball open and enters the internal cavities of electric plunger 12; In the time that plunger moves cavity volume and reduces, produce pressure, the hydraulic medium of electric plunger 12 internal cavities storages enters in the oil circuit of pump cover 4, now, according to the position of selector valve A3 and selector valve B13, hydraulic medium flows to the different parts of spare tyre turnover bracket system or operator cabin lifting hydraulic system oil hydraulic cylinder by the internal oil passages of pump cover 4.
2, when plunger pump adopts manual mode when work, depression bar frame 7 swings under the effect of manpower, then drives manual plunger 6 to overcome self spring resistance and does linear reciprocating motion.Because there is cavity manual plunger 6 inside, in the time that plunger does linear reciprocating motion, manual plunger 6 internal cavities volumes are followed the motion of plunger and change.In the time that plunger cavity volume increases, form oil sucting cavity, make the hydraulic medium of the seal space inside that pump cover 4 and housing 5 form push steel ball open to enter the internal cavities of manual plunger 6; In the time that plunger cavity volume reduces, produce pressure, the hydraulic medium against the force of the spring of manual plunger 6 internal cavities storages, push steel ball open and enter pump cover, in 4 oil circuit, now, according to the position of selector valve A3 and selector valve B13, the internal oil passages that passes through pump cover 4 of hydraulic medium flows to the different parts of spare tyre turnover bracket system or cab turnover hydraulic system oil hydraulic cylinder.
3, in the time that plunger pump adopts electric model or manual mode work, if frequency when electric plunger 12 or manual plunger 6 do linear reciprocating motion is excessive, or other assembly oil circuit being connected with oil hydraulic pump blocks, when the medium of pump cover 4 internal oil passages cannot be discharged in time by cylinder connector A1 or oil connection B2, now hydraulic medium can be pushed non-return device in relief valve 9 open and is back in the seal space that pump cover 4 and housing 5 form under the effect of pressure, and can not produce the situation of damaging oil hydraulic pump component.
4, when plunger pump internal hydraulic pressure medium is filled, and other assemblies that are connected with oil hydraulic pump are while still having hydraulic medium to flow in oil hydraulic pump, hydraulic medium in the seal space that pump cover 4 and housing 5 form can overcome the resistance of stifled 8 contained springs of oil and push steel ball efflux press pump open, avoids occurring damaging the situation generation of oil hydraulic pump.
The above is preferred embodiment of the present utility model, above-mentioned not illustrating done any pro forma restriction to flesh and blood of the present utility model, person of an ordinary skill in the technical field is reading any simple modification or the distortion after this specification, according to technical spirit of the present utility model, above embodiment done, and the technology contents that may utilize above-mentioned announcement is changed or is modified to the equivalent embodiment of equivalent variations, all still belong in the scope of technical solutions of the utility model, and do not deviate from essence of the present utility model and scope.
