How To Maintain The Construction Machinery Hydraulic Cylinder

Hydraulic cylinder is a very important accessory in the construction machinery, its main role includes the realization of the lift function, improve efficiency, safety, transfer of energy, the implementation of the action, regulating pressure and achieve linear motion and so on. It can be seen that the role of the hydraulic cylinder is very important, timely maintenance of the hydraulic cylinder can avoid the occurrence of many problems. So how to maintain the hydraulic cylinder?

 

 

1. Daily Maintenance

 

This includes checking whether the hydraulic cylinder is leaking, whether the action is normal, whether the sound and temperature are abnormal during operation, whether there are scars and pollutants attached to the piston rod, and whether the mounting part is loose, cracked, deformation, etc.

 

 

2. Rust Prevention

 

The piston of the hydraulic cylinder extends out of the cylinder during operation and is bound to suffer from oxides, and acidic gases, so it must be properly lubricated to avoid corrosion of the piston, which is the load-bearing member, leading to damage during use. The surfaces must also be protected from humidity, high temperatures and corrosive gases by a suitable rust inhibitor, and TRUCKMAN offers customized protective covers for hydraulic cylinders to prevent rusting.

 

 

3. Replacement Of Hydraulic Oil

 

Due to long-term use, there will inevitably be impurities in the hydraulic cylinder, which will lead to increased friction. In addition, hydraulic oil also has a service life, if the oil is not changed for a long time, it will cause damage and corrosion to the internal of the hydraulic cylinder. Therefore, it is necessary to regularly replace the hydraulic oil and clean the system filter to ensure the cleanliness of the hydraulic system, thus extending the service life.

 

 

4. Other Maintenance Items

 

a. Regular lubrication of coupling parts: Prevent corrosion or abnormal wear in the absence of oil.

 

b. Move hydraulic cylinders regularly: Avoid seal sticking, inspect stored hydraulic cylinders regularly, and repair or replace damaged parts in a timely manner.

 

c. Regular inspection of seals: The seals of hydraulic cylinders are important parts to prevent oil leakage. Regular inspection of seals for wear and timely replacement of badly worn seals can ensure the normal operation of the hydraulic system.

 

d. Regularly check the piping and connections: The piping and connections of the hydraulic cylinder are important parts of the hydraulic system. Regularly check the sealing, fastening and wear of the pipelines and connectors, and timely treatment and replacement can ensure the normal operation of the hydraulic system.
