Problems solved by technology

Once the high-pressure hydraulic oil is in contact with water, it will form an emulsion and cannot continue to be used, resulting in a large loss of hydraulic oil and increasing the cost of the test
While converting oil pressure to water pressure output, avoid high-pressure hydraulic oil in contact with water. There is currently no good solution

Embodiment Construction

[0010] The present invention will be further described below in conjunction with accompanying drawing.

[0011] Such as figure 1 As shown, an oil-water pressure conversion device of the present invention includes a hydraulic cylinder 1, four electromagnetic switches and a displacement electromagnetic switch 4; there are three hydraulic cylinders 1, one of which is of the type with a ejector rod, and two are without ejector rods type, with ejector rod type hydraulic cylinder 1 controls the displacement electromagnetic switch 4 through the ejector rod displacement, opens and closes to realize the circuit on and off, and controls the displacement electromagnetic switch 4 to open and close; here, when the maximum and minimum strokes of the ejector rod displacement are preset, the hydraulic pressure When the displacement of the ejector rod of cylinder 1 reaches the set maximum and minimum strokes, the trigger displacement electromagnetic switch 4 is opened or closed. The displacem...

Abstract

The invention discloses an oil-water pressure conversion device which comprises hydraulic cylinders, four electromagnetic switches and a displacement electromagnetic switch. The hydraulic cylinders are opened and closed to achieve on and off of a circuit in the manner that an ejector rod moves to control the displacement electromagnetic switch, and the displacement electromagnetic switch is controlled to be switched on and off; the displacement electromagnetic switch is connected with the first electromagnetic switch and the third electromagnetic switch through a first circuit, the displacement electromagnetic switch is connected with the second electromagnetic switch and the fourth electromagnetic switch through a second circuit; the first electromagnetic switch and the second electromagnetic switch are connected with the cylinder bottom ends of the three hydraulic cylinders through pipes; and the third electromagnetic switch and the fourth electromagnetic switch are connected with the piston ends of the three hydraulic cylinders through pipes. By means of the oil-water pressure conversion device, stable oil pressure of a servo hydraulic pressure station can be converted into stable water pressure to be output, and the water pressure loading aim is achieved; and in addition, during oil-water pressure conversion, oil and water separation is achieved, hydraulic oil can be recycled and repeatedly used, and waste is reduced.

Description

technical field [0001] The invention relates to a servo hydraulic station, in particular to an oil-water pressure conversion device. Background technique [0002] The servo hydraulic station provides stable oil pressure, while some model tests need to be loaded with water pressure (such as pore water pressure loading), which is not suitable for oil pressure loading, and the oil pressure needs to be converted into a stable water pressure output. Once the high-pressure hydraulic oil is in contact with water, it will form an emulsion and cannot continue to be used, resulting in a large loss of hydraulic oil and increasing the cost of the test. While converting oil pressure into water pressure output, avoiding high-pressure hydraulic oil and water contact, there is no better solution at present. Contents of the invention [0003] In view of the problems existing in the above-mentioned prior art, the present invention provides an oil-water pressure conversion device, which con...
