Hydraulic cylinder daily maintainance

2023-10-13

Hydraulic cylinder manufacturer always introduce hydraulic cylinder daily maintain or hydraulic cylinder daily maintenance to customers. Hydro cylinder maintenance plays an important role in using hydraulic cylinders. Here I show some hydraulic cylinder maintenance to you.

1.  Adjust hydraulic system’s working pressure, speed, related overflow valve, speed control valve to needed number according to the designed working regulations. And then locked the adjusting screw to prevent loosen.

2. Should be regular check the install and laden connected parts, tighten fastener in time and add lubrication to the part of oiling in time. Check fastener’s sliding wire, bended and other members’ transformation, flaw and so on. once found will be dealt immediately.

3. Pay attention to the increase temperature of working medium. Normal temperature is always below 55 degree, the highest cannot over 80 degree. Once found the temperature increased suddenly or over temperature should check and find out the reasons to removal the fault.

4. Avoid using it in high temperature or using it for a long time. Or it will cause low speed of system and pressure decreased phenomenon.

5. Should constantly be monitoring hydraulic cylinder motion state. Once found speed decreased, crawled, shake, and so on should stop to check and repair soon.

6. Should be regular check the rod, if it has galling, unilateral broken, chromium coating dropped, you’d better stop and separate it and fix.

7. Should be regular check the connected space of hydraulic cylinders controller valve, guide sleeve or cylinder gland. In addition, whether leakage of dust rings or not. Pay attention to the rod motion phenomenon when it works. If it retraction very clear, should separate and check it. If the seals are in bad situation, please change them.

8. Keep hydraulic cylinder especially working space clean, prevent dirty get in. also clean the rod in order to avoid damage seals and moving members.
