What Are The Reasons for Hydraulic Cylinder Leakage?

Internal leakage causes

1. Between the piston and cylinder liner leads to

The wear-resistant ring on the piston is seriously worn, resulting in friction between the piston and cylinder liner, straining the cylinder liner, piston and seal. Cylinder liner inner wall and piston wear and tear resulting in increased clearance over the difference, resulting in high and low pressure chamber communication, when the sewage is acidic and alkaline piston seals easy to corrode, the use of internal scratches, aging, resulting in sealing is not tight, may have caused the mechanical leakage of too large.

2. Piston rod and piston connection position

Piston rod and piston connection between the seal is static sealing, sealing groove is usually opened in the shaft, hydraulic oil is dirty, a large number of impurities into the cylinder will be piston sealing wear and tear to the bad, generally for iron filings or other foreign objects. All will cause the hydraulic cylinder internal leakage.
