Oman hydraulic cylinder,hydraulic telescopic cylinder manufacturer,hydraulic telescopic cylinder(Oman hydraulic telescopic cylinder,produced by Hengyu Hydraulic Co., Ltd)
hydraulic telescopic cylinder are widely used in Oman,because of smooth movement,high work efficiency,excellent fatigue and impact resistance.So our company has designed hydraulic telescopic cylinder for customers from Oman.
When the hydraulic telescopic cylinder is customized, if there are high requirements for the quality of the hydraulic telescopic 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 telescopic 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 telescopic cylinder and avoiding the burn caused by grinding. After rolling, the reduction of surface roughness value can improve the matching property.
After the hydraulic telescopic cylinder is installed, lubricating grease should be added to the relative moving parts such as earring and middle hinge shaft before trial operation.
If air enters the hydraulic system, the hydraulic telescopic cylinder will not operate normally, mainly because there is a leak in the system. At this time, check the liquid level of the hydraulic tank, the seals and fittings on the oil suction side of the hydraulic pump, and whether the oil suction filter is too dirty. If so, the hydraulic oil should be replenished, seals and fittings should be treated, and the coarse filter element should be cleaned or replaced.
When the hydraulic telescopic cylinder is installed on the main engine, the oil port piping part and the guide sleeve should be checked for oil leakage in the running test, and the earring and the middle hinge shaft bearing should be refueled.
Loader arm fell badly, how to know which oil cylinder is leaking?
No matter which cylinder leakage the arm will drop, it is best to replace the oil seal, even if one cylinder is good, it will not last long, and it will drop the arm, so the two cylinders should be replaced at once.
What steel pipe does hydraulic cylinder use? This problem is very general. Carbon steel pipe or ordinary seamless steel pipe are all ok, but then there are rolling, quilting, heat treatment and other steps, and the requirements are different, the wall thickness is different, the material is different. It depends on the circumstances.
