A kind of hydraulic power system, but comprising permanent power oil hydraulic pump, fuel tank and the constant displacement hydraulic motor of motor bidirectional variable, motor links to each other with oil hydraulic pump, is connected by oil pipe respectively between fuel tank, oil hydraulic pump and the oil hydraulic motor.
Hydraulic power system of the present utility model, the oil drain out of wherein said oil hydraulic pump communicates with the filler opening of oil hydraulic motor by first oil pipe, the return opening of oil hydraulic motor communicates with the return opening of oil hydraulic pump by second oil pipe, first oil pipe is provided with first control valve, second oil pipe is provided with second control valve, the drain tap of oil hydraulic pump communicates with fuel tank by drain mast, the repairing mouth of oil hydraulic pump links to each other with first filterpump by the repairing pipe, first filterpump communicates with fuel tank, first filterpump is provided with the 3rd control valve, the drain tap of oil hydraulic motor is connected with second filterpump by second drain mast, second filterpump communicates with fuel tank, and second filterpump is provided with the 4th control valve.
Hydraulic power system of the present utility model, wherein said motor adopts the 220V motor.
Hydraulic power system of the present utility model, during use hydraulic motor output shaft is linked to each other with the sprocket shaft group of equipment, hydraulic power system of the present utility model, output terminal with oil hydraulic motor during use links to each other with the sprocket shaft group of equipment, by controlling output torque and the sense of rotation that oil hydraulic pump comes the regulator solution pressure motor, thereby Quality Initiative axle set speed governing, start and stop and counter-rotating, can be converted into the oil liquid pressure energy by electromechanics, the oil hydraulic motor volume is little, in light weight, movement inertia is little, when frequent start-stop, big starting torque, little when needing speed governing occasion and counter-rotating to the influence of sprocket shaft group.
Description of drawings
Fig. 1 is the structural representation of the utility model hydraulic power system.
Embodiment
As shown in Figure 1, hydraulic power system of the present utility model, comprise motor 1, but the permanent power oil hydraulic pump 2 of bidirectional variable, fuel tank 3, constant displacement hydraulic motor 4, the output shaft of motor 1 links to each other by the input shaft of spline with oil hydraulic pump 2, the oil drain out 23 of oil hydraulic pump 2 communicates with the filler opening 41 of oil hydraulic motor 4 by first oil pipe 24, the return opening 42 of oil hydraulic motor 4 communicates with the return opening 25 of oil hydraulic pump 2 by second oil pipe 43, first oil pipe 24 is provided with first control valve 241, second oil pipe 43 is provided with second control valve 431, the drain tap of oil hydraulic pump 2 communicates with fuel tank 3 by drain mast 22, the repairing mouth of oil hydraulic pump 2 links to each other with first filterpump 7 by repairing pipe 5, first filterpump 7 communicates with fuel tank 3, first filterpump 7 is provided with the 3rd control valve 71, the drain tap of oil hydraulic motor 4 is connected with second filterpump 9 by drain mast 8, second filterpump 9 communicates with fuel tank 3, and second filterpump 9 is provided with the 4th control valve 91.Motor 1 adopts the 220V motor, has substituted the high-voltage motor in the traditional power system, when further having reduced start and stop to the impact of electrical network.
During use, oil hydraulic motor 4 output shafts are linked to each other with the sprocket shaft group 6 of equipment by spline, motor 1 drives oil hydraulic pump 2 work, motor 1 sends kinetic energy to hydraulic pressure potential energy that oil hydraulic pump converts oil hydraulic pump 2 to, oil hydraulic pump 2 is gone into oil hydraulic motor 4 with oil pump, and hydraulic pressure potential energy is passed to oil hydraulic motor 4, and oil hydraulic motor 4 becomes mechanical torque with hydraulic potential energy converting and energy, output torque provides power for transloader sprocket shaft group 6, drives transloader work.By control oil hydraulic pump 2 output torque and the sense of rotation of coming regulator solution pressure motor 4, thus 6 speed governing of control transloader sprocket shaft group, start and stop and counter-rotating.
During hydraulic power system work, first and second control valve 241,431 is opened, when oil hydraulic motor 4 is just changeing, the filler opening 41 that the oil drain out 23 of oil self-hydraulic pump 2 is expelled to oil hydraulic motor 4 enters, oil pressure promotion oil hydraulic motor 4 is just changeing the sprocket shaft group 6 of drive equipment and is just changeing, and flows out to periodic duties in the oil hydraulic pump 2 from return opening 42 then.During oil hydraulic motor 4 counter-rotatings, the return opening 42 that the return opening 25 of oily self-hydraulic pump 2 is expelled to oil hydraulic motor 4 enters, and oil pressure promotes sprocket shaft group 6 counter-rotatings of oil hydraulic motor 4 counter-rotating drive equipment, flows out to periodic duty in the oil hydraulic pump 2 from filler opening 41 then.
When especially oil hydraulic pump 2 is discharged in speed change or start-stop process in the working procedure shortage of oil, open the 3rd control valve 71, by first filterpump 7 extraction of the oil in the fuel tank 3 is delivered in the oil hydraulic pump 2 by repairing pipe 5, the oil that while first filterpump 7 will suck by the filter screen on it in the process of suction oil filters, when the oil in the oil hydraulic motor 4 too much need release, open the 4th control valve 91, by second filterpump 9 oil unnecessary in the oil hydraulic motor 4 is extracted out, by drain mast 8 oil is transported in the fuel tank 3, the oil that while second filterpump 9 will suck by the filter screen on it in the process of suction oil filters.
Above-described embodiment is described preferred implementation of the present utility model; be not that scope of the present utility model is limited; under the prerequisite that does not break away from the utility model design spirit; various distortion and improvement that those of ordinary skills make the technical solution of the utility model all should fall in the definite protection domain of the utility model claims.
