Oman hydraulic hollow cylinder

(Oman hydraulic hollow cylinder,produced by Hebei Hengyu company)

hydraulic hollow cylinder are widely used in Oman,because of no transmission clearance,powerful torque,excellent temperature resistance.So our company has designed hydraulic hollow cylinder for customers from Oman.

Introduction to hydraulic hollow cylinder:

If the seal of the hydraulic hollow cylinder is abnormal wear, you can check whether the speed control valve is improperly adjusted, resulting in too high back pressure and improper installation of the seal or hydraulic oil contamination. The second is whether there is a foreign body entering the assembly and the quality of the sealing material is not good. The result is that the action is slow and weak, and in serious cases, it will cause damage to the piston and hydraulic hollow cylinder, and the phenomenon of "pulling the hydraulic hollow cylinder" appears. The treatment method is to adjust the speed control valve, and the necessary operation and improvement should be done according to the installation instructions.

When the hydraulic hollow cylinder is customized, if there are high requirements for the quality of the hydraulic hollow 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 hydraulic hollow 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 hydraulic hollow cylinder and avoiding the burn caused by grinding. After rolling, the reduction of surface roughness value can improve the matching property.

After the hydraulic hollow cylinder is installed, lubricating grease should be added to the relative moving parts such as earring and middle hinge shaft before trial operation.

The wear of the hard chromium plating layer of the hydraulic hollow 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.

Answers to some questions about hydraulic hollow cylinder:

How to exhaust hydraulic cylinder?
Exhaust: The hydraulic system generally does not have exhaust, the use of the tank can exhaust, the oil operation will bring the gas back to the tank, and the tank can be communicated with the atmosphere. The gas will escape from the oil.

How to repair if hydraulic shears cylinder oil leakage?
The hydraulic cylinder is generally disassembled and the sealing ring is replaced. There are generally two ways to install the ends of the hydraulic cylinder. The larger hydraulic cylinder is mostly flanged disc type, which is screwed to the middle cylinder block by several bolts, the bolts are removed, and the cylinder head is slowly pulled out. The smaller hydraulic cylinder, the cylinder block and the head itself are threaded, and the rotating end cap can be removed from the cylinder block. If you do not understand the hydraulic cylinder, it is best to ask someone to deal with it. It is easy to damage the sealing ring and internal surface during disassembly.
