introduction:one、introduction Leakage is a common fault phenomenon in hydraulic machinery at present,Especially in the construction machinery hydraulic system is more serious,It is mainly due to the pressure difference caused by the liquid flowing in the hydraulic components and pipelines and the gap between the components。In addition,Harsh working conditions will also have a certain impact on the sealing of construction machinery。Once the hydraulic system leaks,It will cause the system stress not to build up,Hydraulic oil leakage can also cause environmental pollution,Affect production and even produce serious consequences that cannot be estimated。The following are some factors affecting the leakage of construction machinery hydraulic system to briefly talk about its leakage
