Summary of the invention
The purpose of the utility model provides a kind of 500T hydraulic press of taking back journey oil pipe line system.
It is existing 500T hydraulic press oil return relief arrangement off-load in time that the utility model will solve, cause plunger cylinder work slowly, insufficient pressure, the hydraulic oil problem of wasting.
For realizing the purpose of the utility model, the technical scheme that the utility model adopts is:
A kind of 500T hydraulic press of taking back the journey pipe-line system; Comprise motor, variable pump, prefill valve, counterbalance valve, oil cylinder, towards the liquid valve, towards liquid fuel tank, balanced valve, reversal valve, flow control valve, buffering fuel reserve tank and main fuel tank; Be equipped with towards the liquid valve and with oil cylinder in the liquid fuel tank and be connected; Oil cylinder top oil pipe is connected with variable pump, motor, prefill valve through reversal valve, and oil cylinder bottom oil pipe is connected with reversal valve, counterbalance valve through balanced valve, and variable pump, prefill valve, counterbalance valve are connected with main fuel tank through pipeline respectively; Carry out off-load towards the liquid fuel tank through direct connection of right side one road pipeline with main fuel tank; Also be connected with main fuel tank towards the liquid fuel tank and carry out off-load through another road return line of left side, the flow control valve that has been installed in series successively on the return line, buffering fuel reserve tank, flow control valve is installed in the top of buffering fuel reserve tank.
Return line is a seamless pipe.
The utility model has the advantages that: this device has increased the oil return latus rectum through increasing a return line system, and the backhaul oil circuit is speeded up, and oil circuit is smooth and easy; Variable pump sound is normal, and each magnetic valve, overflow valve are in proper working order, and oil cylinder operating rate is up and down accelerated, and pressure increases; Reduce the deck of boat and shaped error, improved quality, practiced thrift hydraulic oil again, accelerated manufacturing schedule simultaneously; Improve production efficiency, obtained good economic benefit, should have the market space widely.
Description of drawings
Fig. 1 is a kind of schematic diagram of taking back the 500T hydraulic press of journey pipe-line system of the utility model;
Fig. 2 is the schematic diagram of former 500T hydraulic press;
Among the figure: 1, motor 2, variable pump 3, prefill valve 4, counterbalance valve 5, oil cylinder 6, towards liquid valve 7, towards liquid fuel tank 8, balanced valve 9, reversal valve 10, flow control valve 11, buffering fuel reserve tank 12, main fuel tank.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is further described.
As shown in the figure; A kind of 500T hydraulic press of taking back the journey pipe-line system; Comprise motor 1, variable pump 2, prefill valve 3, counterbalance valve 4, oil cylinder 5, towards liquid valve 6, towards liquid fuel tank 7, balanced valve 8, reversal valve 9, flow control valve 10, buffering fuel reserve tank 11 and main fuel tank 12; Be equipped with towards liquid valve 6 and with oil cylinder 5 in the liquid fuel tank 7 and be connected; Oil cylinder 5 top oil pipes are connected with variable pump 2, motor 1, prefill valve 3 through reversal valve 9, and oil cylinder 5 bottom oil pipes are connected with reversal valve 9, counterbalance valve 4 through balanced valve 8, and variable pump 2, prefill valve 3, counterbalance valve 4 are connected with main fuel tank 12 through pipeline respectively; Carry out off-load towards liquid fuel tank 7 through direct connection of right side one road pipeline with main fuel tank 12; Also be connected with main fuel tank 12 towards liquid fuel tank 7 and carry out off-load through another road return line of left side, the flow control valve 10 that has been installed in series successively on the return line, buffering fuel reserve tank 11, flow control valve 10 is installed in the top of buffering fuel reserve tank 11.
