Piston rod seesaws in being acted on cylinder barrel by external force and makes to produce pressure differential inside and outside cylinder barrel by oil by the most again fluid being forced into operating mechanism in cylinder body entrance press-in cylinder body in use, completes one action.The wearing ring arranged on piston can reduce the friction between piston and inner wall of cylinder, improves the service life of piston.The setting of oil mass display meter can observe the situation of change of oil mass in cylinder barrel timely, in order to finds that the change of cylinder barrel interior oil amount is the most normal in time, if leakage oil condition occur.Because of pressure relief opening and the setting of pressure release handwheel, when needing to disassemble hydraulic hand pump after making to be finished, owing to having certain pressure inside cylinder barrel, at this moment can first pass through rotation pressure release wheel and open pressure relief opening, carry out pressure release, convenient dismounting.And during pressure release, inside and outside cylinder barrel, there is pressure differential, it may appear that and the situation that fluid flows out from pressure relief opening, and the design of drainage trough, then fluid can be guided to flow out from this drainage trough, facilitate the later stage to collect, it is to avoid fluid flees hither and thither, pollute whole hydraulic hand pump.
The described afterbody drawing oil groove is also cased with oil containing bag.This oil containing bag can collect the fluid of outflow, and carries out secondary utilization, to realize maximally utilizing of resource.
Also set up the collar on the outer wall of described drainage trough, the outer wall of cylinder barrel is provided for tangle the bolt of the collar.The then rotatable drainage trough when not using drainage trough, is then enclosed within the collar on bolt, makes drainage trough parallel with cylinder barrel, facilitate the later stage to place and carry.
The bag mouth of described oil containing bag is shrinkage type bag mouth.As required bag mouth size can be adjusted.
Described pressure relief opening and pressure release wheel are installed in the afterbody of cylinder barrel.This design is avoided that pressure release wheel affects hydraulic manual pump work.
Piston primary seal is also set up on described piston.Arranging of primary seal ensures fitting tightly between piston and piston rod, it is ensured that the normal table work of piston rod.
Antifouling ring is also set up on described piston.Avoid the contaminants piston in fluid, cause piston normally to work.
Compared with prior art, the beneficial effects of the utility model are:
1., because of pressure relief opening and the setting of pressure release handwheel, when needing to disassemble hydraulic hand pump after making to be finished, owing to having certain pressure inside cylinder barrel, at this moment can first pass through rotation pressure release wheel and open pressure relief opening, carry out pressure release, convenient dismounting.
2. the setting of oil mass display meter can observe the situation of change of oil mass in cylinder barrel timely, in order to finds that the change of cylinder barrel interior oil amount is the most normal in time, if leakage oil condition occur.
3, the design of drainage trough, then can guide fluid to flow out from this drainage trough, facilitate the later stage to collect, it is to avoid fluid flees hither and thither, pollute whole hydraulic hand pump.
