The cylinder of excavator accessories has a variety of functions, such as power transmission, isolation of wear surface, reduction of friction between components, suspension of pollutants, control of oxidation and cooling of the surface of components, etc.
A lot of people will wonder why iron pieces are found in the oil cylinder of the excavator.
First of all, look at how much these patches are, may be some pipelines/components rinse into, may also be in the production of not clean, residual, or in the usual maintenance inadvertently into the iron sheet, all this should be judged according to the actual situation.
Because various pollutants in the cylinder have a direct impact on the reliability of the cylinder system and the service life of components, Therefore, in order to effectively control the pollution of the hydraulic system, in addition to cleaning components and systems to eliminate residual contaminants during processing and assembly, measures should be taken to prevent contaminants from entering the system to control contaminants from outside.
