How to solve the black oil problem in hydraulic breakers

液压油变黑

Hydraulic breaker has become an important work tool for hydraulic excavators. Some people also install hydraulic breakers on backhoe loaders (also known as busy at both ends) or wheel loaders for crushing operations. When using a hydraulic breaker on an excavator, you will find that the hydraulic oil of the breaker turns black. What is the cause of this phenomenon?

1.Replace the dust ring in time, don’t beat it frequently.

2.Use the butter posture correctly.

3.Install oil return filter device and water spray device to reduce external dust.

4.If the upper and lower bushes are excessively worn, they should be replaced in time.

5.If the intake check valve is damaged or blocked, check the check valve regularly.

6. Pay attention to whether the size of the steel drill rod matches the bushing.

The force of the breaker comes from the oil seal. Without the oil seal, there is no pressure and the hammer cannot work properly. The oil seal isolates the parts that need to be lubricated in the transmission parts from the output parts to avoid leakage. It avoids some problems to a certain extent and is one of the ways to improve the working efficiency of the breaker.
