The utility model adopts following technical scheme: the hydraulic booster and speed-increasing amplifier comprises a cylinder barrel, is fixed on the cylinder cap of cylinder barrel one end band oilhole, the big piston that is positioned at cylinder barrel and seal, have on the cylinder barrel with the piston rod of big piston and casing wall between the oilhole that communicates of the oil pocket that forms; The other end at cylinder barrel is fixed with a guard shield, and there is the small plunger oil path block guard shield end, and the piston rod of big piston can move in guard shield; In the middle of the big piston circular hole is arranged, small plunger is arranged in the circular hole, a pillar stopper rod flange seals up slit between big piston circular hole aperture and small plunger, and small plunger is fixed; The small plunger center has through hole to run through whole small plunger, has the through hole at oilhole and small plunger center to be on good terms on the small plunger oil path block.
Can there be end cap described guard shield end, and there is through hole at the end cap center, and the small plunger end is passed the through hole of end cap and is fixed on the end cap.
Oilhole on the described small plunger oil path block can be positioned at the center of small plunger oil path block.
This hydraulic amplifier, because small plunger has been installed in big piston, when low pressure, through hole by oilhole on the cylinder barrel and small plunger center enters system pressure oil, under the double action of two oil pockets, make big piston fast to the cylinder cap side shifting, form the low pressure speedup.After the low pressure speedup finishes, can continue to promote big piston by small plunger and move forward, prepare for amplifying supercharging.When the oilhole oil-feed of system pressure oil from cylinder cap, the through hole at small plunger center and system oil return are connected, and then play the amplifier pressurization during the logical working cylinder of the oilhole on the cylinder barrel.After the big piston supercharging, the cavity of big piston both sides and small plunger cavity connected tank promote the original position of big piston to speedup by the air pressure of fuel tank, thereby assurance speedup and supercharging all have enough strokes.Owing to big piston is resetted by small plunger and fuel tank air pressure, reduced consumption to system's system pressure oil, therefore can be energy-conservation.This amplifier not only can be applied to common hydraulic system, and the hydraulic machinery that is particularly suitable in the wall floor tile production uses.
Description of drawings
