(Bangladesh roller press hydraulic cylinder,produced by Hebei Hengyu company）

roller press hydraulic cylinder are widely used in Bangladesh，because of simple structure and reliable operation，excellent temperature resistance，no transmission clearance.So our company has designed roller press hydraulic cylinder for customers from Bangladesh.

Introduction to roller press hydraulic cylinder:

In recent years, the processing process of the roller press hydraulic cylinder generally adopts the rolling method, which is a pressure finishing processing, which uses the cold plastic characteristics of the metal at room temperature, and uses the rolling tool to exert a certain pressure on the surface of the workpiece, so that the surface metal of the workpiece produces plastic flow, and fills in the low concave trough of the original residue, and the roughness value of the workpiece surface is reduced. Due to the plastic deformation of the rolled surface metal, the surface tissue is cold hardened and the grain is fine, forming a dense fiber, and forming a residual stress layer, and the hardness and strength are increased, thus improving the wear resistance, corrosion resistance and compatibility of the workpiece surface. Rolling is a plastic machining method without cutting.

The wear of the hard chromium plating layer of the roller press hydraulic cylinder is mostly caused by the grinding of the friction iron powder of the piston, and the wear is faster when there is water in the middle. Corrosion caused by the contact potential difference of the metal only occurs in the part of the piston contact, and the corrosion occurs in a point pattern. As mentioned above, when there is moisture in the middle, it will promote the development of corrosion. Compared with castings, the contact potential difference of copper alloy is higher, so the corrosion degree of copper alloy is more serious.

The roller press hydraulic cylinder should be vented: when the roller press hydraulic cylinder is installed or parked for a long time to work again, the air will penetrate into the roller press hydraulic cylinder and the pipeline system. In order to prevent the abnormal phenomenon of crawling, noise and heating of the actuator, the air in the roller press hydraulic cylinder and the system should be discharged. In order to facilitate the removal of air deposited in the roller press hydraulic cylinder, the oil is best entered and discharged from the highest point of the roller press hydraulic cylinder. roller press hydraulic 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.

In the case of serious wear on the inner surface of the roller press hydraulic 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 roller press hydraulic cylinder manufacturing process for replacement. The roller press hydraulic 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.

Answers to some questions about roller press hydraulic cylinder:

Is it normal for the cylinder to turn black?
Cylinder blackening is a soft fault: 1. It does not affect the normal operation of your equipment. 2. Cylinder blackening involves a lot of things: hydraulic oil, oil seal material, piston rod coating, etc. These three things are not determined by the manufacturer because these three things are provided by other manufacturers. If the equipment is not due to high temperature caused by the black cylinder, you do not have to worry too much because your excavator can still work normally. If you feel uncomfortable, you can choose to replace the cylinder or replace the hydraulic oil.

Is it good or bad for the hydraulic cylinder working in the limit stroke position?
It is not good for the hydraulic cylinder working in the limit stroke position. Generally, when the cylinder is used in the limit stroke, the oil in the cylinder will form a backflow back pressure impact on the piston and guide sleeve seals. If the limit is not accurate, it is easy to cause collision damage. It is recommended to leave a buffer of ten to twenty centimeters.
