Due to the nature of the working environment of excavators, attention should be paid to daily maintenance. When it comes to the maintenance of excavator hydraulic cylinders, I think everyone knows that the purpose is to prevent the hydraulic oil from being contaminated. The specific methods are as follows:

• Regularly replace the oil in the hydraulic cylinder and clean the filter to ensure that it is clean inside and outside.

• Ensure the lubrication of each component to prevent wear and tear when operating without oil.

• Check the tightness of bolts and other components to prevent them from loosening and causing mechanical operation failure.

  
  

• Control the oil temperature to prevent the oil temperature from being too high. When the machinery is operated in a high temperature environment for a long time, the sealing parts will be greatly lost. As time goes by, the seals will be aged and deformed, so that the sealing effect cannot be achieved.
• To prevent scratches and other adverse damage, the sand and dust in the sealing dust ring should be cleaned regularly to block the source of hydraulic oil pollution.
