Why does the Hydraulic Breaker leak oil

The breaking hammer can help us complete the work through the return braking movement and the stroke acceleration movement. Many friends have asked us that the breaking hammer sometimes leaks oil. What is the reason for this? Today we will briefly talk about this issue with you, hoping to bring some reference guidance to your work!

Generally speaking, the causes of oil spills can be roughly divided into the following three aspects:

1. Oil leaks at low pressure and does not leak at high pressure. The reason for this phenomenon is that the roughness of the assembly surface is poor, as long as the surface roughness is properly improved to 3.2~6.3umry and a seal with a lower hardness is used.

2. If oil leaks at low temperature, it does not leak oil at high temperature. There are two reasons for this phenomenon: 1. The eccentricity is too large; 2. The material selection of the seal.

3. If the oil ring of the piston rod becomes larger, a few drops of oil will be dropped in each stroke. If this is the case, the main reason is that the lip of the dust ring scrapes off the oil film, and the type of the dust ring needs to be replaced.

The above points are the main reasons for the oil leakage of the breaker that Xiaobian introduced to you today.
