Further introduce the working procedure of air-driven hydraulic pump in this preferred embodiment below:
(1) pump oil: when the cylinder intake hole 121 of pressurized air from cylinder front cover 12 enters the preceding sealed chamber 18 of cylinder, compressed air-driven cylinder piston 13 and plunger rod 14 be straight line motion left together, shown in the arrow among Fig. 1 and Fig. 2, in cylinder piston 13 and the straight-line left together process of plunger rod 14, above-mentioned piston spring 15 is compressed and produces a restoring force, again owing to be full of hydraulic oil in the plunger cavity 40, so, in the straight-line left process of plunger rod 14, plunger rod 14 just can the compression plunger chamber hydraulic oil in 40, make hydraulic oil supercharging in the plunger cavity 40, the hydraulic oil of supercharging enters in the fuel-displaced oil circuit 60 of fuel-displaced mechanism, the hydraulic oil of supercharging overcomes the elastic force of check valve spring 65, thereby push the steel ball 64 on fuel-displaced one-way valve 61 its steel ball valves 62 open, make steel ball 64 break away from steel ball valve 62, like this, the hydraulic oil of supercharging just enters in the oil cylinder 2 by fuel-displaced oil circuit 60; Behind fuel-displaced finishing, steel ball valve 62 is in the elastic force effect of check valve spring 65 and block the through hole of steel ball valve 62;
When the cylinder piston Sealing 132 on the cylinder piston 13 is crossed the right-hand member of the cylinder barrel ventilation groove 27 on the cylinder barrel 11 left, as shown in Figure 2, cylinder piston Sealing 131 makes piston ventilation groove 26 and back sealed chamber 19 be in not connected state, and piston ventilation groove 26 is communicated with preceding sealed chamber 18 by cylinder barrel ventilation groove 27, therefore, preceding sealed chamber 18 is by piston ventilation groove 26, cylinder barrel ventilation groove 27, ventilation gas circuit 24 is communicated with ventilation chamber 28, like this, the pressurized air of preceding sealed chamber 18, just can be from the cylinder barrel groove 27 of taking a breath, piston ventilation groove 26 flows to ventilation gas circuit 24, enter ventilation chamber 28 through ventilation gas circuit 24 again, pressurized air in the ventilation chamber 28 just can drive scavenging piston 20 and ventilation sealing gasket 25 straight line motion to the right together, thereby make the disengaging of air-vent 23 on ventilation sealing gasket 25 and the cylinder piston 13, like this, pressurized air in the preceding sealed chamber 18, just can enter in the air vent 30 from the gap between ventilation sealing gasket 25 and the air-vent 23, enter in the sealed chamber 19 of back from air vent 30 again, because back sealed chamber 19 is in communication with the outside by exhaust gas circuit 31, so, back sealed chamber 19 just can exhaust gas circuit 31 in, the noise reduction net 32 on exhaust gas circuit 31 is discharged in the atmosphere again;
Because, before pressurized air in the sealed chamber 18 be docile and obedient preface by air-vent 23, air vent 30, back sealed chamber 19, exhaust gas circuit 31 and on noise reduction net 32 be discharged in the atmosphere, so, before sealed chamber 18 compressed airs to the thrust left of cylinder piston 13 just less than the restoring force of piston spring 15, therefore, the restoring force of piston spring 15 just can drive cylinder piston 13 and plunger rod 14 straight line motion to the right together, thereby cylinder piston 13 and plunger rod 14 are resetted rapidly; When cylinder piston 13 and plunger rod 14 are returned to original state, as shown in Figure 1, because the bolt 252 on the ventilation sealing gasket is just inconsistent with the scavenging piston reseting groove, thereby ventilation sealing gasket 25 is sealed on the cylinder piston 13 on the air-vent 23, like this, pressurized air in the preceding sealed chamber 18 just can not enter air vent 30 and arrive in the exhaust gas circuit 31, blocked compressed-air actuated discharge, like this, before sealed chamber 18 compressed airs to the thrust left of cylinder piston 13 during just greater than the restoring force of piston spring 15, therefore, before pressurized air in the sealed chamber 18 just can drive cylinder piston 13 and plunger rod 14 straight line motion left together again, thereby begin next course of action, and so circulation is carried out repeatedly;
In cylinder piston 13 and the straight-line to the right together process of plunger rod 14, form negative pressure in the plunger cavity 40, therefore, hydraulic oil in the fuel tank 1 enters in the oil suction line 50 under the effect of negative pressure, enter the elastic force that oil suction line 50 interior hydraulic oil overcome check valve spring 55, thereby push the steel ball 54 on fuel-displaced one-way valve 51 its steel ball valves 52 open, make steel ball 54 break away from steel ball valve 52, like this, the hydraulic oil that enter in the oil suction line 50 just enter in the plunger cavity 40 by fuel-displaced oil circuit 50, so that use during pump oil next time; After oil suction finished, steel ball valve 52 was in the elastic force effect of check valve spring 55 and block the through hole of steel ball valve 52;
When pump oil mechanism again during pump oil, hydraulic oil just are transported in the oil cylinder 2 again in the plunger cavity 40, and so circulation is carried out repeatedly, thereby realizes the purpose of continuous pump oil.
(2) unloading oil return: when need oil return decline oil cylinder, stop to provide pressurized air, then pressurized air is input on the oil return mechanism on the integrated package 10 to cylinder;
When pressurized air when the oil return inlet hole 73 of oil return mechanism enters oil return air chamber 81, oil return piston 70 slides to the right under compressed-air actuated effect, thereby driving oil return thimble 77 passes to the right, at this moment, return spring 78 is compressed and produces a tension force, before oil return piston 70 arrives during the limit, oil return thimble 77 on the oil return piston 70 just backs down steel ball 94, oil return circuit 74 just is communicated with oil return grease chamber 82, and at this moment, check valve spring 95 is compressed and produces a tension force; Because oil return grease chamber 82 is communicated with fuel tank 1 by decline oil circuit 79, so, oil cylinder 2 is communicated with fuel tank 1 by oil return circuit 74, oil return grease chamber 82, decline oil circuit 79, again since the pressure in the oil cylinder 2 greater than the pressure in the fuel tank 1, so, hydraulic oil in the oil cylinder 2 just can flow back in the fuel tank 1 automatically, thereby finishes the unloading oil return;
When the unloading oil return is finished, stop to oil return inlet hole 73 input pressurized air, oil return piston 70 and on oil return thimble 77 under the effect of return spring 78 tension force, retreat return, therefore, steel ball 94 is rapid return under the effect of check valve spring 95 tension force, oil return piston 70 is sealed once more, gets ready for carrying out pump oil once more.
The above is preferred embodiment of the present utility model only, is not to be used for limiting practical range of the present utility model; Be all equivalents of being done according to claim scope of the present utility model, be claim scope of the present utility model and cover.
