The specific embodiment
Further specify embodiment below in conjunction with accompanying drawing.
With reference to Fig. 1, Fig. 2, Fig. 3,101-high-pressure oil pump, 102-flywheel, 103-motor, 104-oil circuit integrated package, 105-fuel tank, 106-lower shoe, 107-guide upright post, 108-fairlead, 109-portable plate, 110-upper plate, 111-energy-efficient oil cylinder; 201-screen pack, 202-overflow valve, 203-Pressure gauge, 204-magnetic valve F
2, 205-magnetic valve F
3, 206-hydraulic control one-way valve, 301-magnetic valve F
4As shown, one of innovative point of the present utility model is that whole oil cylinder is divided into three cavitys (A, B, C), forms energy-efficient oil cylinder 111; Cavity A is positioned at the center of whole oil cylinder, and cavity B is between piston and cylinder body, and cavity C is positioned at the top of cylinder body.This is that energy-efficient oil cylinder is different from common hydraulic press oil cylinder part.Two of innovative point is that flywheel 102 is installed on the output shaft of motor 103, and this does not have on common hydraulic press yet.Three of innovative point is at magnetic valve F
3Oil line pipe on be connected with hydraulic control one-way valve 206, this valve 206 also can be used magnetic valve F
4Substitute.It mainly is that motor 103 is linked together by flywheel 102 with high-pressure oil pump 101 that mechanism of the present utility model forms, and is fixed on the cover plate of fuel tank 105; Energy-efficient oil cylinder 111 is fixed on the upper plate 110, and portable plate 109 connects with the piston rod of energy-efficient oil cylinder 111 and moves up and down.
The operation principle of this machine is: when equipment need be done F.F., hydraulic oil entered the A chamber of oil cylinder 111, because the A cavity volume is little, made rapid movement so the piston rod in the oil cylinder 111 drives portable plate 110; Simultaneously, the hydraulic oil in the C chamber of oil cylinder 111 is that atmospheric pressure is gone into the oil pressure in the fuel tank 105; When equipment was worked, the B chamber in the oil cylinder 111 and the passageway shuts off of fuel tank 105 were connected with the A chamber simultaneously, strengthen stress surface, add the effect of flywheel 102, made high-pressure oil pump 101 produce high pressure.Like this, just the motor 103 with smaller power drives the bigger hydraulic pump 101 of power, reaches energy-efficient effect.
With reference to Fig. 2, describe hydraulic principle in detail.When piston rod quick when descending, when promptly driving the equipment F.F., magnetic valve F
1Must be electric, hydraulic oil enters the A chamber in the oil cylinder 111, and the A cavity volume is little, thereby make the piston rod in the oil cylinder 111 make fast moving, C chamber in the oil cylinder 111 can produce negative pressure simultaneously, and under the effect of atmospheric pressure, the hydraulic oil process hydraulic control one-way valve 206 in the fuel tank 105 enters the C chamber in the oil cylinder 111.When duty, magnetic valve F
3205 must electricly connect A chamber in the oil cylinder 111 and B chamber, and hydraulic control one-way valve 206 is closed automatically.Hydraulic oil enters the A chamber and the C chamber of oil cylinder 111 simultaneously, and at this moment, the piston rod translational speed slows down, and pressure increases.Under the effect of flywheel 102, can make the motor 103 of smaller power drive the high-pressure oil pump 101 generation high pressure of flow greatly, realize energy-efficient effect.When the piston rod rewind down, F in the magnetic valve 204
1Outage, F
2Logical, hydraulic oil enters the B chamber in the oil cylinder 111, and A chamber oil is through magnetic valve 204 oil sump tanks; C chamber oil is through magnetic valve 205,204 oil sump tanks, and at this moment, hydraulic control one-way valve 206 is opened, and a C chamber oil part is through hydraulic control one-way valve 206 oil sump tanks.
With reference to Fig. 3, because hydraulic control one-way valve 206 changes magnetic valve F into
4301, need its hydraulic principle of explanation: when the need F.F., magnetic valve F
1With magnetic valve F
4301 must be electric, and hydraulic oil enters the A chamber in the oil cylinder 111, and piston rod moves down fast, and simultaneously, the C chamber in the oil cylinder 111 can produce negative pressure, and under the effect of atmospheric pressure, the hydraulic oil in the fuel tank 105 is through magnetic valve F
4301 enter the C chamber in the oil cylinder 111; When duty, magnetic valve F
3205 must be electric, A chamber in the oil cylinder 111 and C chamber are connected, and magnetic valve F
4301 dead electricity are closed the passage of C chamber and fuel tank 105, and hydraulic oil enters the A chamber and the C chamber of oil cylinder 111, and the piston rod translational speed slows down, and pressure increases.
