Working principle of the present invention: under the effect of system pressure, hydraulic fluid flows into pressurized machine from low pressure hydraulic fluid port L, fluid directly flows to high pressure hydraulic fluid port H by pressurization check valve 5 and pressurize safety check 4 or guide's safety check 6, now all fluid is by pressurized machine, and then the actuator of high pressure hydraulic fluid port H side can travel forward fast.Along with oil hydraulic cylinder meets obstructions, the pressure of high pressure hydraulic fluid port H side increases, until reach the pressure maximum that low pressure pump can provide.After reaching the pressure that oil hydraulic pump provides, pressurize safety check 4 and guide's safety check 6 are closed, hydraulic oil flows to high pressure side volume 1, because the pilot pressure SV of now bistable valve selector valve 7 lower end equals system pressure, and the pilot pressure KZ of upper end is zero, therefore bistable state selector valve 7 switches to downside work, and the hydraulic oil in low voltage side volume 3 flows through bistable state selector valve 7 and flows back to fuel tank by oil return side volume 2.After the pressure of pump is delivered to high pressure side volume 1, piston moves downward, after piston moves downward lowermost end, the control mouth KZ of bistable state selector valve 7 upper end is connected with high pressure side volume 1, pressure increases thereupon, the pilot pressure SV of bistable state selector valve 7 lower end remains unchanged, now the pressure of KZ mouth is equal with the pressure of SV mouth, because the upper end active area of bistable state selector valve 7 is larger than the active area of lower end, thus cause bistable valve 7 to be transformed to upper end work, the low voltage side volume 3 of charged piston is directed to from the fluid of low pressure hydraulic fluid port L inflow, piston becomes and moves upward, now pressurization check valve 5 and guide's safety check 6 are in closed condition, thus the liquid after guarantee supercharging flows to actuator by high pressure hydraulic fluid port H.Finally, the pressure of high pressure hydraulic fluid port H side is determined by the area ratio of high pressure side piston 8 with low voltage side piston 9.Once high pressure side piston 8 moves to top, the upper end of bistable state selector valve 7 controls the pressure at mouth KZ place by the volume 2 place's pressure release of oil return side, and the pressure SV of lower end is still and equals low pressure hydraulic fluid port L side pressure, thus automatic switchover bistable state selector valve 7 comes back to the working position of lower end, be cycled to repeat and carry out, until arrive the terminal pressure required, after reaching terminal pressure, pressurized machine is out of service, and only just again runs when needing the pressure maintaining high pressure hydraulic fluid port H side.By return opening R is connected to pressure source, low pressure hydraulic fluid port L is connected to fuel tank, the high-pressure of supercharging side can be discharged by guide's safety check.
Hydraulic pressure intensifier of the present invention can provide the high pressure needed for operation mechanism at any time as required without the need to the high-pressure service pump of costliness and not produce any extra heat and energy loss, this device can compensate on high-tension side leakage flow automatically, ensure reliability and the Security of high pressure side work, there is the advantage that quality is light, volume is little simultaneously.For engineering machinery field and industrial hydraulic field, there is the operation mechanism of partial high pressure demand, the mode that low pressure pump and supercharging device can be adopted to combine realizes the function needed for system, can avoid adopting expensive high-pressure service pump, thus effectively reduce cost, especially can be applied to the design of fastening device, Quick air stroke can be met, the requirement loaded at a slow speed, effectively can ensure the size of clamping force simultaneously, improves the reliability of fastening device work.
Compare double-acting supercharger, it is large that this supercharging device has pressure ratio, the simple advantage of structure.
