El Salvador hydraulic cylinder,yg series hydraulic cylinder manufacturer

(El Salvador yg series hydraulic cylinder,produced by Hengyu Hydraulic Co., Ltd）

yg series hydraulic cylinder are widely used in El Salvador，because of no need for deceleration device，long service life，smooth movement.So our company has designed yg series hydraulic cylinder for customers from El Salvador.

Introduction to yg series hydraulic cylinder:

Before the yg series hydraulic cylinder is removed, the system should be unloaded, the loop pressure is zero, the oil source should be cut off, and the oil port should be blocked after the oil port distribution pipe is loosened.

yg series hydraulic cylinder use should try to avoid sealing belt into the yg series hydraulic 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 yg series hydraulic 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 yg series hydraulic 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.

yg series hydraulic cylinder abnormal sound, hysteresis phenomenon cause and elimination method: the piston rod is extended with abnormal sound and hysteresis, if the yg series hydraulic cylinder is placed for a period of time, the yg series hydraulic cylinder may enter the air, and the movement can be normal after dozens of repeated movements. If it still cannot be eliminated, check whether the load is aligned with the axis of the piston rod; Retracted piston rod installation helps to align the load with the piston rod. If the flow is unstable, it will also lead to abnormal movement of the piston rod. Check the relevant components of the hydraulic system.

There are some honeycomb holes in the inner wall of the yg series hydraulic cylinder, piston or piston rod surface. How is this formed? When we repair the yg series hydraulic cylinder, we can see that there are some honeycomb holes on the inner wall of the yg series hydraulic cylinder, the piston or the piston rod surface, which are caused by cavitation. Therefore, the cavitation of the yg series hydraulic cylinder is targeted to prevent. Is very necessary.

Answers to some questions about yg series hydraulic cylinder:

What is the function of the hinged cylinder of the shield machine?
The articulated cylinder is used for the shield when the radius of curvature is very small during the propulsion process, that is, for turning. For example, a propulsion section with a radius of curvature of R150 can only be turned using an articulated system due to the sensitivity of the shield body (i.e. the length of the shield body divided by its outside diameter). However, in the construction process, the use of articulated systems is not much.

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.
