(Brazil unidirectional cylinder,produced by Hengyu Hydraulic Cylinder Factory）

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

Introduction to unidirectional cylinder:

When the unidirectional cylinder is in use, once the seal and guide support ring are found to be defective, the seal with the same structural form and appropriate material should be replaced according to the structural form of the unidirectional cylinder seal to be repaired, so as to minimize the thickness of the oil film between the seal and the sealing surface and reduce the leakage of the seal.

When the unidirectional cylinder is customized, if there are high requirements for the quality of the unidirectional cylinder, it is best to use rolling processing, because the surface layer has surface residual compressive stress, which helps to close the surface of the small crack, preventing the expansion of erosion. Thus, the corrosion resistance of the surface can be improved, and the fatigue crack can be delayed or expanded, and the fatigue strength of the unidirectional cylinder can be improved. By rolling forming, a cold working hardening layer is formed on the rolling surface, which reduces the elastic and plastic deformation of the contact surface of the grinding pair, thereby improving the wear resistance of the inner wall of the unidirectional cylinder and avoiding the burn caused by grinding. After rolling, the reduction of surface roughness value can improve the matching property.

In the process of using the unidirectional cylinder, sometimes such a problem will occur, the unidirectional cylinder can not act immediately after the instruction of the unidirectional cylinder action is issued, and it must be moved after a short time, or sometimes it can move and stop moving, showing that the operation is very irregular. The cause and elimination of this failure mainly include air in the oil unidirectional cylinder. Elimination method: exhaust through the exhaust valve. Check the piston rod reciprocating parts of the sealing ring for air inhalation, if so, replace the sealing ring.

Disassembly unidirectional cylinder: When disassembly unidirectional cylinder, strictly prevent damage to the screw thread at the top of the piston rod, the screw thread of the unidirectional cylinder head and the surface of the piston rod. It should also be noted that the piston cannot be played out from the unidirectional cylinder.

Answers to some questions about unidirectional cylinder:

What is a differential cylinder?
The differential cylinder is by connecting the return oil of the rod cavity through the pipeline, allowing them to flow into the rodless cavity, thereby speeding up the extension speed of the piston rod. In fact, the cylinder is still the cylinder, but the oil circuit is related to the connection. The oil connection mode in which both chambers of a single rod hydraulic cylinder are fed hydraulic oil is called differential connection.

What adhesive should be used when the cylinder is cracked?
There is a kind of cast iron glue, industrial products market can buy, A, B formula, that is, a tube is A, a tube is B, when used proportionally prepared, check the instructions. Polish the glue after it dries, and then grind it again.
