All Part Numbers All Sizes Hitachi Hydraulic Cylinder For Sale

Maintenance of hitachi hydraulic cylinder:

1. The hydraulic oil should be replaced regularly during the use of the cylinder, and the system filter should be cleaned to ensure cleanliness and prolong service life.

2. Each time the hitachi hydraulic cylinder is used, it needs to carry out 5 strokes of full extension and full retraction and then run with load. This can exhaust the air in the system, preheat each system, and effectively avoid the existence of air or water in the system, which will cause gas explosion (or scorch) in the cylinder block, which will damage the seals and cause leakage in the cylinder. wait for failure.

3. Control the temperature of the system well. If the oil temperature is too high, the service life of the seal will be reduced, and the long-term high oil temperature will cause the seal to be permanently deformed or even fail completely.

4. Protect the outer surface of the piston rod to prevent damage to the seal from bumps and scratches. Always clean the dust ring of the oil cylinder dynamic seal and the sediment on the exposed piston rod to prevent the difficult to clean up sticking on the surface of the piston rod. Dirt entering the inside of the cylinder damages the piston, cylinder barrel or seals.

5. Always check the connection parts such as threads and bolts, and tighten them immediately if they are loose.

6. Always lubricate the joint parts to prevent corrosion or abnormal wear in the oil-free state.
