The reason for the oil leakage of the breaker

2021-03-24

The power device of the breaker is the working pressure oil supplied by the pump room of the excavator or loading truck, which can more reasonably and effectively clean the spar and soil in the crevice of the rock formation, thereby bringing the effect of excavation. The selection standard of this machine and equipment is based on the excavation. The model of the machine and the working environment should be more suitable for the equipment. After realizing the operation of the return brake system and the acceleration of the stroke, the equipment can help us to do a good job. However, the excavator pulverizer sometimes leaks oil, what is the reason? ? Next, I will give you a detailed introduction.

If the piston rod oil ring is enlarged, a small amount of oil will drip on each stroke. In this case, the main reason is that the lip of the dust ring scrapes the oil film, so the type of dust ring must be replaced. It leaks under low pressure conditions, but does not leak under high pressure. The reason for this is that the overall surface roughness of the large breaker is poor. It is enough to moderately increase the surface roughness and use a sealing material with lower hardness .If it leaks at ultra-low temperature, but does not leak at continuous high temperature, there are two reasons for this situation: the eccentricity is too large; the raw material of the sealing material is selected.

In addition, because the 6 angle bolts fall off, there will be oil leakage between the cylinder and the upper body of the big hammer. At this time, you must tighten and replace the damaged O-ring again. At this time, the valve body and the foot must be adjusted. The bolt cover should be overhauled, and the valve body should be re-installed for oil leakage. Under normal circumstances, the grease and anti-rust agent applied on the surface will flow out during reinstallation; the oil leakage between the steel drill and the front cover is serious, and the relevant staff should be careful Check whether the hydraulic oil is leaking. Check whether the sealing ring of the large breaker is damaged, and replace it if necessary; after overhauling and maintaining the main valve and the surface of the cylinder, the reinstalled valve body leaks oil, and the oil must be cleaned. Check whether the oil seal is damaged. If the oil seal is damaged, it must be replaced immediately.
