UAE unidirectional cylinder

(UAE unidirectional cylinder,produced by Hebei Hengyu company)

unidirectional cylinder are widely used in UAE,because of clever hydraulic energy conversion,simple structure and reliable operation,excellent temperature resistance.So our company has designed unidirectional cylinder for customers from UAE.

Introduction to unidirectional cylinder:

unidirectional cylinder use should try to avoid sealing belt into the unidirectional cylinder. As a simple sealing material, polytetrafluoroethylene plastic sealing tape is often used in installation and inspection, and if the winding method of the linear and ribbon-shaped sealing material is wrong, the sealing tape will be cut off and enter the unidirectional cylinder. The wire belt seal will not have any effect on the winding of the sliding part, but it will cause the check valve of the unidirectional cylinder to fail to operate or the buffer regulating valve can not be adjusted to the end. For the circuit, it may cause the action of the reversing valve, the relief valve and the reducing valve to fail.

unidirectional cylinder hydraulic oil selection: The recommended working oil viscosity of the unidirectional cylinder is 10 ~ 110cSt (1.8 ~ 15E), ISO VG46 hydraulic oil. The normal working oil temperature is 10 ~ 70℃, and the ambient temperature is in the range of -20 ~ 80℃. When the ambient temperature and service temperature are low, the hydraulic oil with lower viscosity can be selected.

unidirectional cylinder diameter, rod diameter, stroke determination: Choose national standards or other standards unidirectional cylinder, avoid the selection of non-standard size, otherwise the difficulty of processing and manufacturing costs will be increased. The length of the unidirectional cylinder guide is determined by the length of the stroke. Check the strength of unidirectional cylinder, piston rod, screw, etc. according to the working pressure or load. At the same time, working pressure, ambient temperature, working medium and running speed are also the key to selecting seals.

The "O" ring can be used as an auxiliary seal inside the unidirectional cylinder, and the elastic force of the "O" ring makes the sealing slip ring close to the sealing surface, generating sealing pressure to achieve sealing. When the internal hydraulic pressure increases, the "O" ring will further deform and squeeze the slip ring, thereby increasing the sealing pressure and improving the sealing performance. The structure has the characteristics of low friction coefficient, good wear resistance, automatic compensation for wear and absorption of hard particles in the unidirectional cylinder, and can be completely sealed.

Answers to some questions about unidirectional cylinder:

Why does the hydraulic cylinder rebound after the rod cavity is extended into place?
The reason is that after the rod cavity is extended into place, the rod cavity and the rodless cavity are connected, so that the cylinder moves towards the rod cavity. After connecting, it is equivalent to the hydraulic oil directly driving the cylinder with an area equal to the piston rod. After the end of this problem, it is estimated that the seal is not very good, and the two cavities are connected after the pressure is increased to a certain extent; Or there is a problem in the valve, so that the two chambers are connected after reaching a certain pressure. Other phenomena: If the load is increased to a certain extent, no matter which side of the solenoid valve is energized, the cylinder will move to the rod cavity.

How to remove the air in hydraulic cylinder?
Connected the cylinder to the system, and reciprocating move with full stroke several times, then the air can be eliminated . There is also a clunky method as follows: first remove the rod cavity oil pipe, connect the rodless cavity oil circuit to extend all the cylinders, and then remove the rodless cavity oil pipe, connect the rod cavity oil pipe and withdraw all the cylinders, and then connect the rodless cavity oil pipe, so that there is no air in the cylinder.
