Crushing hammer leakage serious? The old driver will solve it at a glance!

[BONOVO]

Oil leakage area: Serious oil leakage between the drill rod and the front cylinder
Treatment method: It is usually necessary to remove the crushing hammer for inspection, if there is an iron pin on the sealing ring of the piston head, it is because the crushing hammer is seriously worn and caused by oil leakage. In this case, you need to replace the damaged seal.
Case two
Oil leakage area: The surface of the hammer, large valve and hose joints leak oil
Treatment method: Check the status of the breaker hose and bolts, generally due to the hose and bolts loose caused by oil leakage, at this time to re-tighten the bolts.
Case three
Leakage area: valve body and bolt cap
Treatment method: It is likely that the valve body reinstalled after the overhaul of the machine leaks oil, and there is no need to worry about it, which is a normal phenomenon that the lubricating oil and anti-rust oil are applied during installation.
Case four
Leakage area: between the main valve and the cylinder surface
Treatment: It is likely that the valve body after the overhaul of the machine leaks oil, generally do not need to worry, it is likely to be clean oil during the installation, if the inspection result is damaged oil seal, then replace the new oil seal.
Case five
Oil leakage area: between the cylinder and the upper body
Treatment method: First check whether the bolts and nuts of the whole body are loose and leaking oil, if so, re-tighten; Check that all bolts are not loose, but there is oil leakage, you need to replace the damaged O-ring.
Case six
Oil leakage area: oil leakage between the cylinder and the upper and lower body
Treatment: If the oil is leaking at this time, it is necessary to check whether the mounting bolts on the cylinder surface are loose. At this time, only need to tighten again and then replace the oil seal.
In the final analysis, 90% of the above failure conditions can be attributed to the wrong operation of the daily crushing operation, such as empty punching, perpendicular to the crushing material. Therefore, the daily maintenance of the crushing hammer can not be slack.
Through the above, Xiaobian also hopes that excavator operators have a certain understanding of the basic knowledge of crushing hammer disassembly, so that they can judge the fault by themselves and save time and labor to solve the problem.
