Hydraulic hammers usually use hydrostatic pressure as the power to make the piston to perform reciprocating movements. When the piston working and hits the chisel,chisel working on ore, concrete and other solids, which will cause oil leakage in the breaker. When the oil leakage occurs in the breaker, how do we solve it?
Before solving the oil leakage problem of the breaker, we need to know what causes the oil leakage of the breaker.We need check seal kit if good or broken.
When oil leakage between the cylinder and the back head, usually because the bolts and nuts are loose. At this time, it is necessary to re-tighten and replace the damaged O-ring.
When an oil leakage between the cylinder and the front head. First we need check carefully check that is grease oil or hydraulic oil, and then check the seal kit. If there is damage on seal kit, it needs to be replaced in time.
Oil leakage occurs at low pressure, but does not occur at high pressure. The main reason for this problem is that the roughness of the assembly surface of the breaker is too poor, the surface roughness can be improved and the seal with relatively low hardness can be used for sealing.
After the control valve and the surface of the cylinder have undergone a major maintenance process, the new control valve body has oil leakage, and the oil needs to be cleaned to see if the oil seal is damaged. If the oil seal is found to be damaged, it must be replaced immediately.
The hydraulic breaker is very afraid of oil leakage. Once oil leakage occurs in any part, we should be stop immediately, and the breaker should be inspected in detail.
