 1. Oil leakage between the cylinder cone and the guide sleeve of the hydraulic cone crusher: the static seal between the cylinder tube and the guide sleeve. The seal ring has poor quality, insufficient preload, scratched or twisted deformation, rough machining of the cylinder barrel and the guide sleeve, and the like, which can cause oil leakage between the cylinder tube and the outer seal of the guide sleeve.

2. The oil leakage of the hydraulic cone crusher piston rod and the cylinder cover: The cylinder, the cylinder head, the piston rod and the piston are processed and assembled poorly, or the piston rod is bent and deformed. When the hydraulic cylinder is working, the piston rod and cylinder axis are inclined. The unilateral deformation of the cylinder head sealing ring caused oil leakage at the piston rod and the cylinder head.
 
3. Oil leakage between the contact surfaces of the piston rod and the guide sleeve of the hydraulic cone crusher: The oil leakage between the piston rod and the relative movement surface of the guide sleeve is mostly due to the damage of the seal ring installed on the guide sleeve and the surface damage of the piston rod. Causes oil spills.
 
4. Oil leakage between cylinder and cylinder head of hydraulic cone crusher: The seal material of the cylinder cover is of high hardness, aging, damage or repeated use. When the seal is repaired or damaged, it will cause oil leakage.
 
5, hydraulic cone crusher hydraulic cylinder parts caused by oil leaks: due to cylinder and cylinder head manufacturing defects, or guide sleeve with sand holes, porosity or shrinkage and other casting defects, under the pressure of the hydraulic system, the defect gradually expanded Causes oil spills.
