(Turkmenistan stroke adjustable cylinder,produced by Hengyu Hydraulic Cylinder Factory）

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

Introduction to stroke adjustable cylinder:

When the stroke adjustable cylinder is kept, do not pay attention to keeping the oil port open, which will produce the condition of accepting foreign bodies at all times, which is absolutely not allowed. Storage must be filled with anti-rust oil or working oil, and plug.

The stroke adjustable cylinder should be vented: when the stroke adjustable cylinder is installed or parked for a long time to work again, the air will penetrate into the stroke adjustable cylinder and the pipeline system. In order to prevent the abnormal phenomenon of crawling, noise and heating of the actuator, the air in the stroke adjustable cylinder and the system should be discharged. In order to facilitate the removal of air deposited in the stroke adjustable cylinder, the oil is best entered and discharged from the highest point of the stroke adjustable cylinder. stroke adjustable 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.

If the stroke adjustable cylinder operation failure, you can start from these aspects to troubleshoot: (1) the hydraulic system control pressure is too low. The throttling resistance in the control line may be too large, the flow valve is improperly adjusted, the control pressure is inappropriate, and the pressure source is disturbed. At this time, the control pressure source should be checked to ensure that the pressure is adjusted to the specified value of the system; (2) Air enters the hydraulic system. Mainly because there is a leak in the system. At this time, check the liquid level of the hydraulic tank, the seals and fittings on the oil suction side of the hydraulic pump, and whether the oil suction filter is too dirty. If so, the hydraulic oil should be replenished, seals and fittings should be treated, and the coarse filter element should be cleaned or replaced. (3) The initial action of the stroke adjustable cylinder is slow. In the case of low temperature, the hydraulic oil viscosity is large, poor flow, resulting in slow stroke adjustable cylinder action. The improvement method is to replace the hydraulic oil with better viscosity and temperature performance If the stroke adjustable cylinder is weak and cannot push the load, please check the internal leakage problem. The internal leakage of the stroke adjustable cylinder includes the leakage caused by excessive wear of the stroke adjustable cylinder block seal, the piston rod and the seal cover seal and the piston seal. The cause of sealing leakage between the piston rod and the seal cover is that the seal is wrinkled, squeezed, torn, worn, aging, deterioration, deformation, etc., and a new seal should be replaced at this time. The main cause of excessive piston seal wear is improper adjustment of the speed control valve, resulting in excessive back pressure and improper seal installation or hydraulic oil contamination. The second is that foreign bodies enter the assembly and the quality of sealing materials is not good. The result is that the action is slow and weak, and in serious cases, it will cause damage to the piston and stroke adjustable cylinder, and the phenomenon of "pulling the stroke adjustable cylinder" appears. The treatment method is to adjust the speed control valve, and the necessary operations should be done according to the installation instructions.

The stroke adjustable cylinder should be used as far as possible to avoid the transverse force, sometimes the piston rod to bear the transverse load is too large, especially do not force or pull the stroke adjustable cylinder, bite. Elimination method: When installing the stroke adjustable cylinder, ensure that the axis position of the stroke adjustable cylinder is consistent with the direction of movement; Make the load borne by the stroke adjustable cylinder as far as possible through the stroke adjustable cylinder axis, to avoid the phenomenon of eccentricity.

Answers to some questions about stroke adjustable cylinder:

What material should be selected to seal the cylinder?
The choice of material for sealing is related to the working environment, strength, and medium of your equipment.

How to calculate the cylinder diameter, rod diameter and pressure of the cylinder, and how to output tonnage?
Hydraulic cylinder output force F=PAX10^3(KN) F is the output force (KN), P working pressure (MPa), A is the piston or plunger area of action.
