The content of the invention
In view of the above-mentioned problems of the prior art, the utility model provides a kind of profit pressure conversion device, will be stable Oil pressure is converted to the device of stable hydraulic pressure output, can realize oil-water pressure conversion, at the same by piston separate hydraulic oil and Water, avoid high pressure liquid force feed from meeting water emulsification and cause to waste.
To achieve these goals, the technical solution adopted in the utility model is:A kind of profit pressure conversion device, including Hydraulic cylinder, four electromagnetic switch and displacement electromagnetic switch;The hydraulic cylinder has three, and one of hydraulic cylinder is to have push rod type, Two are without push rod type, have push rod type hydraulic cylinder by push rod displacement command displacement electromagnetic switch, open and closure realizes circuit Break-make, command displacement electromagnetic switch is opened and closure;The displacement electromagnetic switch is opened with the first electromagnetism respectively by the first circuit Close, the connection of the 3rd electromagnetic switch, displacement electromagnetic switch is connected with the second electromagnetic switch, the 4th electromagnetic switch respectively by second circuit Connect;First electromagnetic switch, the second electromagnetic switch are connected by pipeline respectively at three hydraulic cylinder bottoms;3rd electricity Magnetic switch, the 4th electromagnetic switch are connected by piston end of the pipeline respectively with three hydraulic cylinders;First electromagnetic switch connects Water injecting pipeline is connect, second electromagnetic switch connects hydraulic pressure output pipe, and the 3rd electromagnetic switch connects hydraulic oil recovery tube Road connects, and the 4th electromagnetic switch connects oil pressure intake line.
The utility model is further, and the pipeline uses high-pressure rubber pipe.
The utility model is further, when the hydraulic cylinder push rod displacement reaches the minimum and maximum stroke of setting, triggering Displacement electromagnetic switch is opened and closure.
The utility model profit pressure conversion device, by displacement electromagnetic switch in device loading procedure, utilize hydraulic cylinder Mandril position shifter control circuit break-make, control electromagnetic switch is opened and closure, and the stable oil pressure at servo-hydraulic station can be utilized to realize Stable hydraulic pressure output, realizes " loading-hydraulic cylinder moisturizing-hydraulic oil recovery-piston playback-loading " this profit pressure conversion journey Sequence, and when carrying out profit pressure conversion, oil is separated with water by piston in hydraulic cylinder, avoids high pressure liquid force feed from meeting water emulsification Cause to waste, hydraulic oil can be reused by loop, reduced and wasted.

Fig. 1 is hydraulic principle block diagram of the present utility model;
In figure:1st, hydraulic cylinder, 2, piston, 3, push rod, 4, displacement electromagnetic switch, the 5, first circuit, 6, second circuit, 7, high Moulding pipe, the 8, first electromagnetic switch, the 9, second electromagnetic switch, the 10, the 3rd electromagnetic switch, the 11, the 4th electromagnetic switch, 12, water filling Pipeline, 13, hydraulic pressure output pipe, 14, hydraulic oil recovery pipe, 15, oil pressure intake line.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As shown in figure 1, a kind of profit pressure conversion device of the utility model, including hydraulic cylinder 1, four electromagnetic switch and position Move electromagnetic switch 4;Hydraulic cylinder 1 has three, and for one of hydraulic cylinder 1 to there is push rod type, two are without push rod type, there is push rod type liquid Cylinder pressure 1 is opened by push rod displacement command displacement electromagnetic switch 4 and closure realizes connecting and disconnecting of the circuit, command displacement electromagnetic switch 4 is opened Open and close;When having here preset at the minimum and maximum stroke of push rod displacement, the push rod displacement of hydraulic cylinder 1 reaches the maximum and most of setting During small stroke, the closure or openness of triggering displacement electromagnetic switch 4.Displacement electromagnetic switch 4 by the first circuit 5 respectively with the first electromagnetism The 8, the 3rd electromagnetic switch 10 of switch connects, and displacement electromagnetic switch 4 is electric with the second electromagnetic switch the 9, the 4th respectively by second circuit 6 Magnetic switch 11 connects;First electromagnetic switch 8, the second electromagnetic switch 9 are connected by pipeline respectively at three cylinder bottom ends of hydraulic cylinder 1 Connect;3rd electromagnetic switch 10, the 4th electromagnetic switch 11 are connected by piston end of the pipeline respectively with three hydraulic cylinders 1; First electromagnetic switch 8 connects water injecting pipeline 12, and the second electromagnetic switch 9 connection hydraulic pressure output pipe 13, the 3rd electromagnetic switch 10 connects Connect hydraulic oil recovery pipe 14 to connect, the 4th electromagnetic switch 11 connection oil pressure intake line 15.
The utility model hydraulic cylinder is divided into two classes, and one kind is that another kind is has push rod type, the liquid for having push rod type without push rod type Cylinder pressure push rod is subjected to displacement in loading procedure, touches displacement switch, realizes connecting and disconnecting of the circuit, and control electromagnetic switch is opened and closed Close.There is piston inside hydraulic cylinder, piston plays a part of oil-water separation and transmits pressure.
On the basis of said structure, the utility model pipeline uses high-pressure rubber pipe, has excellent oil resistant, heat-resisting, resistance to old Change performance, bearing capacity is high, and pulse behaviors are superior, and body is tightly combined, and using softness, deform under stress small.
