According to statistics, the hydraulic system fault is the first among the total number of failures in every system. What factors are the causes of hydraulic system leakage? How to solve it?
The leakage of the vertical roller mill hydraulic system is mainly caused by the pressure difference and the gap between the components when the liquid flows in the hydraulic components and pipelines. There are two types of oil discharge in the vertical roller mill hydraulic system.
One is the oil discharge sealed by the static joint surface (i.e. the fixed part, mainly including the joint between cylinder head and cylinder barrel, the connection of each pipe joint, etc.); The second is the oil release of the sealing of the dynamic joint surface (i.e. sliding part, mainly including multi-channel valve stem, cylinder piston and inner wall of cylinder barrel, piston rod and guide sleeve of cylinder head, etc.).
