unidirectional cylinder are widely used in Indonesia，because of excellent temperature resistance，no transmission clearance，powerful torque.So our company has designed unidirectional cylinder for customers from Indonesia.

Introduction to unidirectional cylinder:

The unidirectional cylinder should be vented: when the unidirectional cylinder is installed or parked for a long time to work again, the air will penetrate into the unidirectional cylinder and the pipeline system. In order to prevent the abnormal phenomenon of crawling, noise and heating of the actuator, the air in the unidirectional cylinder and the system should be discharged. In order to facilitate the removal of air deposited in the unidirectional cylinder, the oil is best entered and discharged from the highest point of the unidirectional cylinder. unidirectional cylinders that require higher motion stability are often equipped with exhaust plugs at both ends. Before working, unscrew the exhaust plug to make the piston go back and forth several times without load in the whole stroke, and the air can be discharged through the exhaust plug. After the air is drained, tighten the exhaust plug before working.

The scar on the sliding surface of the unidirectional cylinder piston will transfer with use. Before the piston is installed, there are scars on its sliding surface, which are installed intact and untreated, and these scars will in turn scratch the inner surface of the unidirectional cylinder wall. Therefore, before installation, these scars must be fully repaired.

When the initial action of the unidirectional cylinder is slow, please check the temperature of the hydraulic system, because in the case of low temperature, the viscosity of the hydraulic oil is large and the fluidity is poor, resulting in slow action of the unidirectional cylinder. The improvement method is to replace the hydraulic oil with good viscosity temperature performance, and the oil temperature at low temperature can be increased by heater or heating by the machine itself, and the normal working oil temperature of the system should be maintained at about 40 ° C.

Do not enter foreign bodies when installing the unidirectional cylinder block. The place where the installation operation is carried out, the conditions are not good, and foreign bodies can be entered unconsciously. Therefore, the installation site must be cleaned up around, especially the place where the parts are placed must be cleaned, so that there is no dirt.

Answers to some questions about unidirectional cylinder:

How to repair if hydraulic shears cylinder oil leakage?
The hydraulic cylinder is generally disassembled and the sealing ring is replaced. There are generally two ways to install the ends of the hydraulic cylinder. The larger hydraulic cylinder is mostly flanged disc type, which is screwed to the middle cylinder block by several bolts, the bolts are removed, and the cylinder head is slowly pulled out. The smaller hydraulic cylinder, the cylinder block and the head itself are threaded, and the rotating end cap can be removed from the cylinder block. If you do not understand the hydraulic cylinder, it is best to ask someone to deal with it. It is easy to damage the sealing ring and internal surface during disassembly.

Why does the hydraulic cylinder go up to the top and then slowly go down?
Leakage in the cylinder or the hydraulic valve that controls the cylinder, can be replaced and removed. Or add a pressure retaining valve to the hydraulic system to ensure pressure.
