Product Details

The internal leakage of the hydraulic cylinder is not easy to detect during the operation of the hydraulic cylinder. When the hydraulic system fails, the internal leakage is often ignored. Today, I will share a hydraulic cylinder internal leakage inspection method and some measures to prevent internal leakage.

Internal leakage of hydraulic cylinder

Internal leakage is the leakage of the hydraulic oil in the hydraulic components from the high-pressure chamber to the low-pressure chamber. According to the structure of the hydraulic cylinder, the internal leakage of the hydraulic cylinder generally occurs in two parts, between the piston and the inner wall of the cylinder barrel; the connection between the piston rod and the piston
