(Congo unidirectional cylinder,produced by Hebei Hengyu company）

unidirectional cylinder are widely used in Congo，because of simple structure and reliable operation，no transmission clearance，high work efficiency.So our company has designed unidirectional cylinder for customers from Congo.

Introduction to unidirectional cylinder:

In the case of serious wear on the inner surface of the unidirectional cylinder, or when there is a deep longitudinal tensile mark, it should be mapped according to the physical object and re-produced by the professional manufacturer according to the unidirectional cylinder manufacturing process for replacement. The unidirectional cylinder can also be repaired with TS311 antiwear repair agent. TS311 anti-wear repair agent is mainly used for the repair of worn and slipped metal parts.

unidirectional cylinder seal leakage causes and countermeasures: a. Loose tie rod nut will cause leakage, tighten the tie rod nut according to the torque requirements of tie rod nut, test no leakage can continue to use. b. Pressure exceeding the limit will also cause leakage. Replace the unidirectional cylinder seal and re-tighten the tie rod nut to reduce the pressure to the nominal pressure range of the unidirectional cylinder. c. The unidirectional cylinder seal is extruded, if the O-ring is obviously extruded at the unidirectional cylinder seal, replace the unidirectional cylinder seal.

The repair method of unidirectional cylinder wear: 1. Metal repair material is applied to the scratched surface; The first layer should be thin, uniform and fully covered with the scratched surface to ensure the best adhesion between the material and the metal surface, and then apply the material to the entire repair site and press repeatedly to ensure that the material is filled and reaches the required thickness, so that it is slightly higher than the surface of the guide rail; 2, the material at 24℃ to fully achieve the performance of 24 hours, in order to save time, can be through the tungsten halogen lamp to increase the temperature, the temperature rises 11℃, the curing time will be reduced by half, the best curing temperature 70℃; 3. After the material is cured, use a fine grinding stone or a scraper to repair and smooth the material higher than the surface of the guide rail, and the construction is completed.

When installing the piston rod, it is necessary to ensure that the direction of the connecting head at the top of the piston rod should be consistent with the direction of the unidirectional cylinder head adn the earring (or the middle hinge shaft), and ensure the straightness of the whole piston rod during the advance and return process to prevent the phenomenon of rigid interference and causing unnecessary damage.

Answers to some questions about unidirectional cylinder:

Can pneumatic cylinder be used as hydraulic cylinder?
The pneumatic cylinder can only be used for pressure below 1MPA, and if it is used for hydraulic, the pressure should be under 1MPA, which may not meet the strength requirements. And the seals should use fluorine rubber to avoid corrosion. But pneumatic cylinder used as hydraulic cylinder is not whimsical, in fact, there is such a use. The pneumatic system has a natural defect, that is, the speed is unstable, especially in the case of low speed. The hydraulic pressure is very stable, if you do not want to buy a set of hydraulic system, while the strength of the cylinder is not large, you can use compressed air to push the hydraulic oil, with hydraulic oil to drive the cylinder, The force is the same as compressed air, but very smooth.

What is the meaning of dead volume in hydraulic cylinder?
Closed volume, also known as dead zone volume Positive displacement pump is dependent on the change of sealing working volume to achieve suction and pressure oil, in order not to make the suction and pressure oil cavity interworking, there is an oil sealing area between the suction and pressure oil cavity, when the sealing working volume passes through the oil sealing area, neither pressure oil cavity nor oil suction cavity communication, forming a closed sealing volume. The unloading groove is opened, and the grooving principle is that the sealing volume decreases and the oil pressure chamber is communicated, and the sealing volume increases and the oil suction chamber is communicated.
