(Burma retractable cylinder,produced by Hengyu Group）

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

Introduction to retractable cylinder:

After the retractable cylinder is installed, lubricating grease should be added to the relative moving parts such as earring and middle hinge shaft before trial operation.

When the piston speed of the retractable cylinder is high, the steel ball of the check valve flows with the oil flow, so that the valve hole is blocked, and the retractable cylinder moves irregularly. Elimination method: Replace the steel ball with a cone valve or spool with a guide shoulder.

In the process of using the retractable cylinder, sometimes such a problem will occur, the retractable cylinder can not act immediately after the instruction of the retractable cylinder action is issued, and it must be moved after a short time, or sometimes it can move and stop moving, showing that the operation is very irregular. The cause and elimination of this failure mainly include air in the oil retractable cylinder. Elimination method: exhaust through the exhaust valve. Check the piston rod reciprocating parts of the sealing ring for air inhalation, if so, replace the sealing ring.

If the seal of the retractable cylinder is softened and sticky, it may be that the seal is incompatible with the hydraulic oil or the nearby lubricating oil, replace the appropriate seal; If the seal becomes hard and loses elasticity, most of it is because the ambient temperature is too high (more than 80 ° C), make appropriate temperature insulation protection or replace the high temperature seal.

Answers to some questions about retractable cylinder:

What brand of hydraulic cylinder seal ring is best?
Depending on the specific product, the world famous seal brands are NOK, CFW, PARKER, TSS, WKF, DINGZING DZ, ASTON, HALLITE, TECNOLAN and so on.

Are hydraulic cylinders divided into oil cylinders and water cylinders? What's the difference between the two types?
There are oil cylinders and water cylinders. The two cylinders are used in different environments. Oil cylinders are generally used in places where there is less demand for media, which is our most common hydraulic cylinders. Water cylinders are mainly used for large tonnage presses. Because the equipment is too large, the use of hydraulic oil will cause a relatively large waste. However, water is not pure water, there are oil-in-water emulsion and water-in-oil emulsion. Water has another benefit: it's flame retardant. It is especially suitable for some flammable and explosive occasions. Or with water glycol. The use of pure water is very little, mainly because the seal is not good and easy to rust.
