Why does the drill rod piston leak?

In order to maintain the normal operation and use efficiency of the large breaking hammer, it is required that the relevant components such as the piston have sufficient strength and hardness. In the case of severe impact, the contact surface between the piston and the drill rod will not be deformed, cracked or broken. , the side reflects that the quality of the drill rod must have high wear resistance. Once the piston leaks, the resulting low cylinder pressure caused by the piston leak will affect the normal use of the breaker.
Regarding the method to solve the air leakage of the large breaker piston, if the air leakage is not serious, inject a small amount of oil into the cylinder in the injector hole, the air leakage sound will be significantly reduced, and the compression force will be significantly improved. If the cylinder compression force of a diesel engine is insufficient, and the symptoms meet the above characteristics, it can be judged that the piston is leaking. In the case of no decompression, the crankshaft can be shaken, indicating that the cylinder has serious air leakage. In addition, when the diesel engine is running, if the cylinder leaks, the sound of air leakage can be heard at the oil filling port, and there is smoke coming out here.
Insufficient elasticity of the piston ring of the large breaker, the piston ring goes to the opposite end, the opening clearance or edge clearance of the piston ring is too large, and the piston ring or cylinder liner wears excessively, etc., which will cause the piston to leak air. After finding out the reason, take corresponding measures, including replacing damaged or substandard parts, reinstalling and debugging, etc.
