If the hydraulic oil is used for a long time and is not replaced, the impurities in the hydraulic oil (iron filings, copper filings, dust, etc.) will accumulate more and more, and the fine particle size will become smaller and smaller. Such impurities are sometimes fundamental to the naked eye. What is invisible is that it is very small, and it will easily pass through the hydraulic oil filter.

At the same time, if the hydraulic oil is used for too long, the various characteristics of the hydraulic oil, such as lubrication performance, viscosity characteristics, anti-wear performance, and stiffness characteristics, will be greatly reduced. Impurities in the hydraulic oil are brought to the various working devices and control components through the working cycle, which directly leads to the rapid wear of the hydraulic components of the entire hydraulic system. Prevention is regular
