In figure: 1, oil is stifled, 2, manual plunger, 3, bearing, 4, the pump housing, 5, selector valve, 6, oil connection A, 7, oil connection B, 8, electric plunger, 9, direct current generator, 10, relief valve, 11, oil tank, 12, filter screen set.
Embodiment
This lifting truck cab system electric-manual integrated hydraulic planger pump is stifled 1 by oil, manual plunger 2, bearing 3, the pump housing 4, selector valve 5, oil connection A6, oil connection B7, electric plunger 8, direct current generator 9, relief valve 10, oil tank 11 and filter screen set 12 form, direct current generator 9 is bolted on the upper end of the pump housing 4, on the axle of direct current generator 9, be fixed with bearing 3, the lower end of the pump housing 4 is fixed with oil tank 11 by bolt, and relief valve 10 and filter screen set 12 are equipped with in the pump housing 4 lower ends in oil tank 11; A wherein side of the pump housing 4 is provided with oil stifled 1 and manual plunger 2, the opposite side that the pump housing 4 is relative with this side is provided with oil connection A6 and oil connection B7, in the pump housing 4 side adjacent with this side, selector valve 5 is installed, electric plunger 8 is installed in the pump housing 4, and electric plunger 8 passes through oilhole UNICOM with selector valve 5.(referring to accompanying drawing 1～2)
The working procedure of this lifting truck cab system electric-manual integrated hydraulic planger pump is as follows:
1, when lifting truck cab system electric-manual integrated hydraulic planger pump adopts electric model when work, direct current generator 9 starts to rotate, and band dynamic bearing 3 does eccentric rotary, then makes electric plunger 8 overcome self spring resistance and does linear reciprocating motion.Owing to having cavity in electric plunger 8, in the time that plunger does linear reciprocating motion, electric plunger 8 internal cavities volumes are followed the motion of plunger and change.In the time that plunger rises, cavity volume changes from small to big, and produces negative pressure, makes hydraulic medium in oil tank 11 suck the internal cavities of electric plunger 8 by filter screen set 12; In the time that plunger declines, cavity volume compression, produce pressure, the resistance that the hydraulic medium of electric plunger 8 cavity insides overcomes taper spring is pushed open in the oil circuit that steel ball enters the pump housing 4, now according to the residing position of selector valve 5, hydraulic medium enters in other assemblies that are connected with lifting truck cab system electric-manual integrated hydraulic planger pump by flow through oil connection A6 or oil connection B7 of the pump housing 4 internal oil passages.
2, in the time that lifting truck cab system electric-manual integrated hydraulic planger pump adopts manual mode work, manual plunger 2 does straight reciprocating motion under the promotion of manpower.Owing to having cavity between manual plunger 2 and the pump housing 4, in the time that plunger rises, the cavity volume between manual plunger 2 and the pump housing 4 changes from small to big, and produces suction, and the hydraulic medium in oil tank 11 is sucked by filter screen set 12 in the cavity of manual plunger 2 and the pump housing 4; In the time that plunger declines, cavity volume between manual plunger 2 and the pump housing 4 reduces, produce pressure, the resistance that hydraulic medium in cavity overcomes cylindrical spring is pushed open in the oil circuit that steel ball enters the pump housing 4, now according to the residing position of selector valve 5, hydraulic medium enters in other assemblies that are connected with lifting truck cab system electric-manual integrated hydraulic planger pump by flow through oil connection A6 or oil connection B7 of the pump housing 4 internal oil passages.
3, in the time that lifting truck cab system electric-manual integrated hydraulic planger pump adopts electric model or manual mode work, if frequency when electric plunger 8 or manual plunger 2 do linear reciprocating motion is excessive, or other assembly oil circuits that are connected with lifting truck cab system electric-manual integrated hydraulic planger pump are while stopping up, the hydraulic medium of the pump housing 4 internal oil passages cannot be discharged in time by oil connection A6 or oil connection B7, the non-return device that now hydraulic medium can be pushed open in one-way valve 10 under the effect of pressure is back in oil tank 11, and can not produce the situation of damaging truck hoisting system electric and manual manipulation one hydraulic planger pump component.
4, when other assembly hydraulic mediums that are connected with lifting truck cab system electric-manual integrated hydraulic planger pump are back to hydraulic planger pump inside, and hydraulic medium in the oil tank 11 of hydraulic planger pump is while having filled, hydraulic medium can overcome the resistance of stifled 1 contained spring of oil and push steel ball efflux hydraulic plunger pump open, avoids occurring that the situation of damaging lifting truck cab system electric-manual integrated hydraulic planger pump occurs.
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.
