Korea unidirectional cylinder

(Korea unidirectional cylinder,produced by Hengyu Hydraulic Co., Ltd)

unidirectional cylinder are widely used in Korea,because of high work efficiency,excellent fatigue and impact resistance,no need for deceleration device.So our company has designed unidirectional cylinder for customers from Korea.

Introduction to unidirectional cylinder:

When the oil pressure of the unidirectional cylinder inlet is too low to reach the specified value, the leakage situation of the relevant oil system should be checked and the leakage should be eliminated; Check the piston and piston rod seal ring for damage, aging, loose and other phenomena; Check whether the hydraulic pump and pressure valve are faulty.

The meaning of the unidirectional cylinder model marked by the unidirectional cylinder manufacturer: for example, 160/100-1150, its meaning: from a professional point of view, 160 refers to the unidirectional cylinder diameter, which is 160mm, and the 100 behind refers to the rod diameter, which is 100mm. The 1150 refers to the unidirectional cylinder stroke, which is 1150mm. Therefore, on this point, we should have a correct understanding and can not make mistakes.

The quality of the unidirectional cylinder can not be ignored in the purchase of the unidirectional cylinder. The unidirectional cylinder is the main component of the unidirectional cylinder, the single pillar for mining, the hydraulic support, the gun tube and other products, and its processing quality directly affects the life and reliability of the entire product. unidirectional cylinder processing requirements are high, its internal surface roughness requirements are Ra0.4 ~ 0.8μm, the coaxiality, wear resistance requirements are strict. The basic feature of unidirectional cylinder is deep hole processing, which has always troubled the processing personnel.

We can not just consider the price and ignore the quality when we purchase the unidirectional cylinders. Now some manufacturers produce unqualified products in order to reduce costs, the piston rod is not adjusted, the rod coating is not enough, the unidirectional cylinder finish can not reach, the guide sleeve should use copper, but instead of ductile iron, although the cost is reduced, the quality of the unidirectional cylinder is not required.

Answers to some questions about unidirectional cylinder:

Can multiple identical hydraulic cylinders be supplied with the same supply line?
This can be connected, but there is a disadvantage, that is, the hydraulic cylinder with the minimum pressure is extended first, and then the pressure is higher, and then the higher, until all the hydraulic cylinders are extended, which may not meet the requirements of field use.

What type of seal is the cylinder of shaft 50?
You won't know the exact model until you take it apart. Oil seals have O, Y, Yx, KYx, U, UN, UHS, YA, St, Gray, Yamagata, Lei type, etc. It is difficult to know what kind of oil seal the designer chooses. Cylinder oil seal installation method: 1. Receive a fixed number of oil seals. 2. From receiving the oil seal to assembly, it must be kept clean. 3. Before assembly, check the oil seal and measure whether the size of each part of the oil seal is consistent with the size of the shaft and cavity. Before the oil seal is installed, the size of the shaft diameter should be clearly compared with the inner diameter of the oil seal. The inner cavity size should be suitable for the outer diameter width of the oil seal. Check the lip of the oil seal for damage.
