Description
The utility model belongs to liquid, the dual-purpose hydraulic bidirectional supercharging equipment of gas.
Common high-pressure hydraulic, general plunger pump, multistage compression pump, multistage vane pump, the diaphragm pump of adopting waits and does high pressure fuel source, its deficiency is that its power consumption is big, volume is big, noise is big, maintenance operation cost height, thereby influence applying in hydraulic pressure, the pocket servo-system of high pressure.
The purpose of this utility model provides the common low pressure source of a kind of employing, and implementation structure is simple, energy-conservation, low noise, the two-way supercharger that pressurized effect is good.
The purpose of this utility model is achieved through the following technical solutions: it is made up of the piston oil-cylinder in the pressurization body, one-way valve, voltage stabilizing cylinder, pressure gauge, pressure relay, solenoid directional control valve, fuel tank, it is characterized in that: the solenoid directional control valve (9) that links to each other with low pressure source (10) is equipped with reverser K through the A mouth
2Piston oil-cylinder R in low-pressure cavity (7), piston oil-cylinder R inner carrier (6) connects piston (2) in the piston oil-cylinder L by piston rod (4), is provided with reverser K
1Piston oil-cylinder L low-pressure cavity (1) by the road to another interface of solenoid directional control valve (9) B; Hyperbaric chamber (3) in the piston oil-cylinder L and the hyperbaric chamber (5) in the piston oil-cylinder R are connected to fuel tank (8) and voltage stabilizing cylinder (12) respectively through sucking one-way valve C, D and discharge one-way valve F, E.Be connected with pressure gauge (13) and pressure relay (11) on the voltage stabilizing cylinder (12).
The low pressure source (10) that the utility model flows into the low pressure supplying tube can be a liquid, also can be gas; Voltage stabilizing cylinder (12) is that a high-voltage power supply is used to export high pressure; Voltage stabilizing cylinder (12) output terminal can be used for connecting high-pressure cylinder or high-pressure nozzle, can be added with supplementary equipment such as throttle valve, relief valve before connecting high-pressure cylinder or high-pressure nozzle.
This two-way supercharger has following advantage:
Owing to be to adopt common low pressure source to become high-voltage power supply through pressurization, make it simple in structure, volume is little, can realize consuming energy little, noise is low, supercharging efficient height; Its cost is low, is 10%～20% of former high-pressure system; In addition, the low pressure input can be gas and also can be liquid, is widely used.
Fig. 1 is a structural principle schematic representation of the present utility model.
Below in conjunction with accompanying drawing working principle of the present utility model 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
7, 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 utility model (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
