Slovakia unidirectional cylinder,unidirectional cylinder manufacturer

(Slovakia unidirectional cylinder,produced by Hebei Hengyu company）

unidirectional cylinder are widely used in Slovakia，because of smooth movement，simple structure and reliable operation，powerful torque.So our company has designed unidirectional cylinder for customers from Slovakia.

Introduction to unidirectional cylinder:

How to repair the unidirectional cylinder body when it is damaged: When the unidirectional cylinder has trace deformation and shallow tensile marks, the unidirectional cylinder is repaired by strong honing process. The heavy honing process can repair unidirectional cylinders up to 2.5 times out of tolerance than the original tolerance. It honed the parts with excessive size or shape error through a powerful honing machine, so that the overall size, shape tolerance and roughness of the unidirectional cylinder can meet the technical requirements.

In order to ensure the service life of the unidirectional cylinder, the medium used must not be mixed with impurities and stolen goods, so as to avoid scratching the inner arm of the unidirectional cylinder, causing damage to the seal and causing leakage in the unidirectional cylinder. It is required that the filtration accuracy of the system is not less than 80μm, the oil pollution is strictly controlled, the hydraulic oil is kept clean, the performance of the hydraulic oil is regularly checked, and the necessary fine filtration or replacement of the new working hydraulic oil is carried out.

Improve the service life of the unidirectional cylinder: it is necessary to maintain the normal clearance of the combined surface of the hydraulic components. When manufacturing or repairing the main parts of the unidirectional cylinder (such as the unidirectional cylinder block, piston rod, etc.), the assembly should be carried out in accordance with the tolerance lower limit of the assembly size, which can well reduce the occurrence of cavitation. If cavitation has occurred in the hydraulic components, only metallographic sandpaper polishing technology can be used to remove cavitation pitting and surface carbon deposits, and general fine sandpaper must not be used for polishing After the unidirectional cylinder is repaired, the hydraulic system should run smoothly for a certain period of time so that the hydraulic oil in the hydraulic system can be fully circulated; If necessary, the unidirectional cylinder inlet pipe (or return pipe) can be disassembled. Make the hydraulic oil overflow to achieve the effect of single unidirectional cylinder exhaust.

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.

Answers to some questions about unidirectional cylinder:

What is the thin cylinder used for?
The principle is no different from ordinary cylinders, that is, the installation space is small, the formation is small, and it is suitable for some special occasions. For example, the space is compact and the place of small travel is used.

What hydraulic valve is used to control a cylinder back and forth?
Direction valve is available. Direction valve includes electromagnetic directional valve, manual directional valve, check valve, hydraulic control check valve, the specific choice of which direction valve, you need to see the use of conditions.
