(Czech Republic tension cylinder,produced by Hengyu Group）

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

Introduction to tension cylinder:

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

After chrome plating of the piston rod of the tension 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.

Factors that should be considered when selecting the oil seal in the tension cylinder: some specific factors should be taken into account when selecting the oil seal in the tension cylinder, so as to have correct consideration and get accurate results, and then avoid wrong selection. The factors and aspects that should be taken into account are eight: tension cylinder diameter, piston rod diameter, piston rod and piston groove size, tension cylinder working pressure, tension cylinder movement speed, hydraulic system oil temperature and tension cylinder working environment.

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

Answers to some questions about tension cylinder:

A hydraulic system functions three cylinders to maintain pressure, what components need to be used?
Two way cartridge valve can be selected for control. Two way cartridge valve advantages: 1) flow capacity is large, especially suitable for large flow occasions. 2) The spool has sensitive action and strong anti-clogging ability. 3) Good sealing, small leakage, oil flow through the valve pressure loss is small. 4) Simple structure, easy to standardize.

Can a leak in the cylinder cause the hydraulic system to fail?
Leakage in the cylinder can cause the hydraulic system to fail. Cylinder leakage (internal leakage) first affects the controlled action of the hydraulic system can not meet the requirements (such as the movement speed of the cylinder, the insufficient thrust and tension of the cylinder), if the internal leakage of the cylinder is too large, it may also cause the cylinder to be unable to promote the load movement. Second, the existence of internal leakage (internal leakage) of the oil cylinder will lead to the rapid rise (or too high) of the oil temperature of the hydraulic system, and the high oil temperature will not only waste the energy conversion of the system, but also lead to the reduction of the viscosity of the oil, which will accelerate the aging and destruction of the seals such as pumps, valves, cylinders, pipelines, and at the same time, the lubrication effect of the hydraulic oil is reduced, and the production of iron filings that increase the friction of the hydraulic system.
