Embodiment
The present invention is further illustrated with preferred embodiment by reference to the accompanying drawings now.These accompanying drawings are the schematic diagram of simplification, basic structure of the present invention is only described in a schematic way, so it only show the formation relevant with the present invention.
A kind of Pneumatic booster pump that can be fuel-displaced continuously as shown in Figure 1 and Figure 2, the gas piston 4 that comprises upper pump casing 1, lower pump body 2, is connected to cylinder block 3 between the upper and lower pump housing 1,2, is slidably matched with cylinder block 3 inwalls and the plunger 5 being connected with gas piston 4, on lower pump body 2, be connected with high pressure valve body 6, plunger 5 front ends put in the inner chamber of high pressure valve body 6, high pressure valve body 6 front ends are connected with oil suction seat 7, and high pressure valve body 6 sidewalls are connected with oil discharging seat 8.
In the middle of the inner chamber of described high pressure valve body 6, there is a spacer ring 15, spacer ring 15 is divided into front interior cavity and rear interior cavity by described inner chamber, plunger 5 is slidably matched with spacer ring 15 endoporus, wherein the lower end of front interior cavity is communicated with the oil sucting cavity of oil suction seat 7, the upper end sidewall of front interior cavity is provided with oblique oil duct 14, the oil pocket that goes out by these oil duct 14 front interior cavities and oil discharging seat 8 is communicated with, in oil suction seat 7, be provided with oil sucting one-way valve 9, in oil discharging seat 8, be provided with the oil outlet one-way valve in opening state 10 all the time, be positioned at plunger 5 front ends of front interior cavity, be provided with the sliding sleeve 11 sliding up and down along described front interior cavity inwall, in sliding sleeve 11, be provided with the plunger one-way valve 12 contrary with oil sucting one-way valve 9 open and-shut modes.
Between described sliding sleeve 11 upper-end surfaces and the bottom surface of spacer ring 15, form a hydraulic pressure cavity 13 of holding high pressure oil, the intracavity section that the sectional area of described hydraulic pressure cavity 13 is less than high pressure valve body 6 amasss.
Working procedure is summarized as follows: when gas piston 4 is during in cylinder block 3 top dead center position shown in figure, in the front interior cavity of plunger one-way valve 12 belows, be full of hydraulic oil, from upper pump casing 1 to the interior beginning air feed of cylinder block 3, promote gas piston 4 descending and synchronously drive plunger 5 descending, at this moment plunger one-way valve 12 is opened, oil sucting one-way valve 9 is closed, oil outlet one-way valve 10 is opened, the hydraulic oil that is positioned at front interior cavity flows to hydraulic pressure cavity 13 by plunger one-way valve 12, the long-pending sectional area that is greater than hydraulic pressure cavity 13 of intracavity section due to high pressure valve body 6, cause the hydraulic oil flowing in hydraulic pressure cavity 13 to be greater than the volume of hydraulic pressure cavity 13, unnecessary hydraulic oil is outwards flowed out from oil outlet one-way valve 10 by oil duct 14.
When gas piston 4 runs to cylinder block 3 bottom dead center position, from lower pump body 2 to the interior beginning air inlet of cylinder block 3, promote gas piston 4 up and synchronously drive plunger 5 up.Now in the hydraulic pressure cavity 13 on plunger one-way valve 12 tops, be full of hydraulic oil, plunger one-way valve 12 is in closed condition simultaneously, oil sucting one-way valve 9 is opened, oil outlet one-way valve 10 is still in open mode, hydraulic oil in hydraulic pressure cavity 13 is due to the effect of pressure, hydraulic oil flows out through oil outlet one-way valve 10 by oil duct 14, and outside hydraulic oil sucks through oil sucting one-way valve 9 front interior cavity that is positioned at plunger one-way valve 12 lower ends, thereby complete one fuel-displaced, the working procedure of oil-feed, go round and begin again circulation and realize the fuel-displaced continuously of Pneumatic booster pump, guaranteed the work that hydraulic system is continual and steady.
The present invention is simple in structure, the occasion that is suitable for narrow space, the usage requirement of high-volume hydraulic pump, it is by arranging a plunger one-way valve 12 at plunger 5 front ends, relying on pressurized air to promote plunger 5 moves up and down, make oil sucting one-way valve 9 and plunger one-way valve 12 alternately open, close, high pressure oil constantly flows out from oil outlet one-way valve 10, can significantly increase the ultrahigh-pressure hydraulic oil flow of output per minute, thereby realize the continuous fuel-displaced and stable work of the Pneumatic booster pump constant in the situation that at form structure and delivery pressure.
Above-described embodiment is only explanation technical conceive of the present invention and feature; its object is to allow person skilled in the art can understand content of the present invention and be implemented; 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, and all should be encompassed in protection scope of the present invention.
