Abstract
A super-high-pressure hand-pressed oil pump comprises an oil inlet valve, an oil outlet valve, an oil return valve and an oil pump shell. The utility model is characterized in that the oil inlet valve, the oil outlet valve and the oil return valve are directly arranged in the oil pump body; an oil inlet valve core cavity, an oil outlet valve core cavity and an oil return valve core cavity are directly arranged on the oil pump body; each cavity passage forms a sealed loop. The problem of the easy leakage of the pump body after highly pressed is solved in the utility model. The oil pump in the utility model can be improved in output oil pressure, be extended the service life and be applied to various super-high-pressure manual oil pumps.
Description
The utility model relates to each high pressure oil pump, particularly discloses a kind of hand-pushing superpressure oil pump.
Present domestic existing hand-pushing superpressure oil pump, the component that it is main: oiling valve, outlet valve, scavenger valve are combined into one by bolt and oil pump body.Therefore the connecting part of these parts easily produces seepage after standing high pressure, causes the pressure index of oil pump to can not get guaranteeing the working life of having reduced oil pump.This constitutional detail is many simultaneously, and the volume of assembling back product is big, carry inconvenience.Chinese patent CN9720569.1 " manual reverse of direction high pressure oil pump " has introduced a kind of high pressure manual oil pump with two oil circuits, it has solved the continuity of plunger work, but this patent patent exists its main component to link to each other with oil pump case by screw equally, easily produces seepage after standing high pressure.
The purpose of this utility model is to provide a kind of main parts size oiling valve, outlet valve, scavenger valve and oil pump body with oil pump to be combined into a kind of hand-pushing superpressure oil pump.
The purpose of this utility model is achieved in that the hand-pushing superpressure oil pump, comprise oiling valve, outlet valve, scavenger valve and oil pump case, spool can be conical sphere shape, it is characterized in that: with oiling valve, outlet valve, scavenger valve is set directly in the pump housing of oil pump, the oil-feed spool chamber directly is set in the pump housing, fuel-displaced spool chamber, the oil return spool chamber, the oil-feed spool chamber is positioned at the pump housing center Lower Half that takes over, spool chamber axis and pump housing axis normal, there is the fuel-displaced spool chamber with the parallel higher position of oil-feed spool chamber in the left side, fuel-displaced spool chamber is positioned at pump housing middle part, its below is an oil road, be provided with the passage parallel between oil road and the oil-feed spool chamber with pump housing axis, pump housing head has and the angled oil return spool chamber of pump housing axis, be provided with the back oil road parallel with pump housing axis between oil return spool chamber and the fuel tank, each chamber and passage form sealed circuit.
The beneficial effects of the utility model are: because main parts size oiling valve, outlet valve, scavenger valve and the oil pump case of oil pump is combined into one, the oil circuit of the pump housing does not have leakage point, can make oil pressure can reach 200Mpa-400Mpa, the oil pump output oil pressure is stable, pressure drop is little, use sensitivity to improve, and improves 4-6 the working life of oil pump doubly.
