Description
Technical field
The utility model relates to the structure of high-pressure cylinder.
Background technique
High voltage stabilizing cylinder, for realizing the loading supercharging of the testing installation such as seamless steel pipe, elbow, is applicable to the subjects of different size.High voltage stabilizing cylinder utilizes principles of fluid mechanics, by piston area than the output realizing high pressure water, is converted to by the pressure that the oil hydraulic cylinder using hydraulic oil as medium produces and uses water as in the cylinder body of medium, thus outwards provide power.
Existing high voltage stabilizing cylinder product is by pressure transducer detected pressures, and the control system of voltage stabilizing cylinder is regulated, because pressure transducer also exists the feature also improved with rated pressure rising price thereupon, the output maximum pressure of high voltage stabilizing cylinder is generally no more than 70MPa, simultaneously the output discharge capacity of also uncontrollable high pressure water.Therefore, be necessary to improve existing high voltage stabilizing cylinder, improve it and export maximum pressure, and it is adjustable to realize high pressure water output discharge capacity.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of high voltage stabilizing cylinder guaranteeing oil-water separation.
The purpose of this utility model is achieved in that high voltage stabilizing cylinder, comprise base, base connects high pressure cylinder barrel, cylinder tube from the bottom to top successively, oil cylinder cap, above high pressure cylinder barrel, also lower oil cylinder cover is set, lower oil cylinder cover is fixed in the lower end of cylinder tube, in cylinder tube, be equipped with piston, piston connects piston rod, the lower end of piston rod is arranged in high pressure cylinder barrel through after lower oil cylinder cover; The second guide pin bushing, the second seal ring, spacer ring, the first seal ring, the first guide pin bushing is set gradually from the bottom to top between described piston rod and high pressure cylinder barrel; Cover at described upper cylinder and rodless cavity hydraulic fluid port is set, cylinder tube arranges rod chamber hydraulic fluid port, intake-outlet is set in the lower end of high pressure cylinder barrel.
Utility model works process is as follows: high voltage stabilizing cylinder is formed primarily of oil pocket and water cavity, fluid enters oil pocket by filler opening, thus promotion piston moves, piston rod plays piston action in voltage stabilizing cylinder water cavity, utilize principles of fluid mechanics, by piston area than the output realizing high pressure water, high pressure water output discharge capacity regulates by control piston displacement simultaneously.Adopt two guide sleeve structure between piston rod and high-pressure cylinder tube wall surface, effectively isolated two media, realize water oil and be separated.
The utility model is by utilizing the difference of piston and rod areas, and loaded the output realizing 90MPa high pressure water by oil hydraulic cylinder, the ratio of gains can reach 1:5.67, and oil cylinder adopts two guide sleeve structure to realize water oil and is separated.
As improvement of the present utility model, cover connection bit displacement sensor at described upper cylinder, axially arrange blind hole on the piston rod, the test end of displacement transducer is arranged in the blind hole of piston rod.By the displacement of magnetostrictive displacement sensor control piston, the final output discharge capacity controlling high pressure water.
As further improvement of the utility model, in the lower end of described oil cylinder cover, the oil drain out be connected all is set with the lower end of cylinder tube; Arrange drain opening in the upper end of described high pressure cylinder barrel, drain opening is arranged on the top of the first guide pin bushing.Oil cylinder cover and high pressure cylinder barrel have oil drain out and drain opening, the unnecessary medium in high voltage stabilizing cylinder working process can be discharged.
