(Puerto Rico servo cylinder,produced by Hengyu Hydraulic Co., Ltd）

servo cylinder are widely used in Puerto Rico，because of long service life，smooth movement，high work efficiency.So our company has designed servo cylinder for customers from Puerto Rico.

Introduction to servo cylinder:

When the hydraulic oil is not pumped into the servo cylinder, it is necessary to check whether the tubing, oil circuit, especially the hose joint has been blocked, and the relevant oil circuit from the servo cylinder to the pump should be checked in turn and blocked; Check whether the seal between the taper valve and the seat of the relief valve is good; Check whether the solenoid valve spring is damaged or whether the solenoid coil is burned out; Whether the oil circuit is switched is insensitive.

After chrome plating of the piston rod of the servo cylinder, the surface flatness is not fully treated: After chrome plating of the piston rod surface, the method of post-plating polishing should be changed to post-plating polishing. Although it is necessary to increase the thickness of the coating before grinding (generally increased by about 0.02 in the diameter direction), it can remove chrome plating defects well, and test the binding force of the coating. In addition, due to the micro-roughness of the grinding surface, the trough can store lubricating oil, which can improve the wear resistance and extend the service life.

The servo cylinder can not be used as grounding electrode to avoid electric damage to the piston rod.

Causes and countermeasures of oil servo cylinder leakage: Cast iron ring seal allows a certain degree of internal leakage. The impurities in the servo cylinder will lead to premature wear of the piston seal, replace the piston seal; If the servo cylinder is visibly scarred, the servo cylinder must be replaced. It can be pressurized at one end of the servo cylinder and opened at the other end of the oil port to observe whether there is obvious internal leakage at the end of the oil port. Most servo cylinder piston drift may not come from the servo cylinder, the above method to determine the servo cylinder without internal leakage is helpful to determine the problem of the hydraulic system related components.

Answers to some questions about servo cylinder:

Two cylinders have a reversing control, if the load of the two cylinders is not the same, how to ensure their synchronization?
The piston rod of the cylinder is required to extend synchronization: install A shunt collector valve or synchronous motor at port A of the direction control valve, and then connect the two outlets of the shunt collector valve to the rod-free cavity of the two cylinders respectively. It is required that the outlet of the diverter collector valve is connected to the rod cavity of the two cylinders respectively when the piston rod is withdrawn in synchronization. The synchronization performance depends on the quality of the diverter valve and the leakage of the hydraulic system.

How to distinguish high pressure cylinder and low pressure cylinder?
There is no special definition of the cylinder, the so-called pressure classification refers to the pump low pressure (code L) container 0.1MPa ≤p < 1.6MPa; Medium pressure (code M) container 1.6MPa ≤p < 10.0MPa; High pressure (code H) vessel 10 MPa≤p < 100 MPa; Ultra-high pressure (code U) container p≥100MPa. (1MPa=9.8Kg)
