Description of drawings
Fig. 1 is a structural principle schematic representation of the present invention.
Embodiment
Below in conjunction with accompanying drawing working principle of the present invention is described below:
The low-pressure fluid that is come by low pressure source (10) enters low-pressure cavity in the piston oil-cylinder R (7) through the P-A hole of solenoid directional control valve (9), promoting piston (6) is moved to the left, hyperbaric chamber (5) volume in the piston oil-cylinder R begins to dwindle, and makes the fluid of supercharging enter voltage stabilizing cylinder (12) through discharging one-way valve E; Hyperbaric chamber (3) in the piston oil-cylinder L is because the volume increase, pressure reduces, atmospheric pressure is pressed into hyperbaric chamber (3) in the piston oil-cylinder L with the oil in the fuel tank (8) through sucking one-way valve C, low-pressure cavity (1) volume in the piston oil-cylinder L dwindles, and fluid is got back to fuel tank (8) by pipeline through the B-O mouth of solenoid directional control valve (9).When piston is moved to the left to the reverser K that piston oil-cylinder L inner bottom part will be touched in the precalculated position
1, by K
1Send signal and make solenoid directional control valve (9) commutation.After solenoid directional control valve (9) commutation, the low-pressure cavity (1) that the P-B mouth of low-pressure fluid process solenoid directional control valve (9) enters piston oil-cylinder L, promote piston (2) and move right, the volume in the piston oil-cylinder A inner high voltage chamber (3) reduces, and high pressure oil enters voltage stabilizing cylinder (12) through discharging one-way valve F; Hyperbaric chamber among the piston oil-cylinder R (5) internal volume increases, pressure reduces, barometric pressure is pressed into the oil in the fuel tank (8) in the piston oil-cylinder R hyperbaric chamber (5) through sucking one-way valve D, and the fluid in the piston oil-cylinder R in the low-pressure cavity (7) is got back to fuel tank (8) through the A-O mouth of solenoid directional control valve (9); When moving right the precalculated position, piston touches piston oil-cylinder R bottom reverser K
2, by K
2Send signal and make solenoid directional control valve (9) commutation.Bidirectional-movement makes high-pressure liquid constantly enter into voltage stabilizing cylinder (12) and so forth, makes the voltage stabilizing cylinder become a high-voltage power supply.Pressure gauge (13) on voltage stabilizing cylinder (12) shows the pressure in the voltage stabilizing cylinder, when pressure reaches setting value, send signal by pressure relay (11), three position four-way electromagnetic valve (9) is mediated, P, A, B, O hole are all not through-flow, and pressure-increasing machine quits work; When pressure is lower than setting value, signal by pressure relay (11), make solenoid directional control valve (9) in running order, P-A, B-O are connected, start working.
Pressure relay of the present invention (11) also can adopt micro-processor controlled pressure transducer.When adopting hydraulic oil, with reverser K as low pressure source (10)
1With reverser K
2Move on to and increase outside the body of hole, with reverser connecting rod (14) the control reverser K that is connected in the piston two ends
1With reverser K
