NBR Durable Hydraulic Breaker Mechanical Seal 135MM Oil Resistant For DMB210
When oil leakage is found in the seal of the crushing hammer, first check whether there is any abnormality in the sealing area.
1. The oil ring of the piston rod becomes larger, and oil will drop in each stroke. The cause is that the oil film is scraped off at the lip of the dust ring and the dust ring is replaced
2. Oil leakage at low pressure and no oil leakage at high pressure. The reason is that the assembly surface is rough. Change the surface roughness to 3.2 ~ 6.3 umry, and use seals with lower hardness
3. There are two reasons for oil leakage at low temperature and no oil leakage at high temperature. One is that the eccentricity is too large, and the other is that the material selection of the seal is inappropriate, which can be solved by selecting the cold resistant seal.
