Four precautions for use of hydraulic cylinder

1. Pay attention to the protection of the outer surface of the piston rod during daily use. Prevent the damage to the seal caused by bumps and scratches.
2. During daily use, attention should also be paid to the regular inspection of all threads, bolts and other connecting parts. If any looseness is found, tighten it immediately.
3. Usually, the test run of full extension and full contraction shall be carried out for 3-5 strokes before operation. The purpose of this is to exhaust the air in the system and preheat each system. This can effectively avoid the presence of air or water in the system. If there is air or water in the system, it may cause gas explosion in the cylinder block. This will damage the seals and cause internal leakage of the oil cylinder.
4. During daily maintenance, pay attention to replacing hydraulic oil regularly. Clean the system filter screen in time. Ensure the cleanliness of hydraulic oil. This plays a very important role in extending the service life of the hydraulic cylinder.
