Sudan hydraulic cylinder,swager cylinder manufacturer,swager cylinder
(Sudan swager cylinder,produced by Hengyu Hydraulic Co., Ltd）
swager cylinder are widely used in Sudan，because of long service life，smooth movement，high work efficiency.So our company has designed swager cylinder for customers from Sudan.
The daily inspection of the swager cylinder includes: checking the connection of the swager cylinder and the pipe joint for leaks. Check the swager cylinder rod for leaks. Check the swager cylinder connection for leaks. When the swager cylinder moves, the work is normal and smooth. Whether the swager cylinder has internal leakage.
The swager cylinder should be vented: when the swager cylinder is installed or parked for a long time to work again, the air will penetrate into the swager cylinder and the pipeline system. In order to prevent the abnormal phenomenon of crawling, noise and heating of the actuator, the air in the swager cylinder and the system should be discharged. In order to facilitate the removal of air deposited in the swager cylinder, the oil is best entered and discharged from the highest point of the swager cylinder. swager 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.
When the swager cylinder thrust is insufficient, check the hydraulic circuit for leaks. Including leakage of valves and hydraulic lines. The inspection method is to check and eliminate the leakage of the hydraulic connection line by manipulating the reversing valve. Also consider the relief valve. If the relief valve enters the dirt and jams the spool, so that the relief valve is normally open, the hydraulic oil will flow directly back to the tank through the relief valve bypass, resulting in no oil in the swager cylinder. If the load is too large, although the regulating pressure of the relief valve has reached the maximum rating, the swager cylinder still cannot get the thrust required for continuous action without action. If the regulating pressure is low, the pressure is insufficient to achieve the required vertebra force, which is manifested as insufficient thrust. Check and adjust the relief valve at this time.
After chrome plating of the piston rod of the swager cylinder, the surface flatness is not fully treated: After chrome plating of the piston rod surface, the method of post-plating polishing should be changed to post-plating polishing. Although it is necessary to increase the thickness of the coating before grinding (generally increased by about 0.02 in the diameter direction), it can remove chrome plating defects well, and test the binding force of the coating. In addition, due to the micro-roughness of the grinding surface, the trough can store lubricating oil, which can improve the wear resistance and extend the service life.
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 do cylinder internal leakage and external leakage mean?
Internal leakage means that the piston seal in the cylinder is not strict, there is a leak between the two chambers of the cylinder, the oil is still in the cylinder, and the external leakage is that the oil leaks to the outside of the cylinder.
