1、 Reasons for hydraulic system leakage(1) Defects caused by design and manufacturing;(2) Loose pipe joints caused by impact and vibration;(3) Wear and tear between dynamic seals and mating components (especially in hydraulic cylinders);(4) The oil temperature is too high and the rubber seal is inc

Working principle: The hydraulic cylinder, as an executing component, is essentially an energy conversion device. The hydraulic cylinder converts the pressure energy of the input liquid into the mechanical energy of the piston's linear motion.The so-called input hydraulic energy refers to the fl

The various test indicators and working performance of the hydraulic cylinder before leaving the factory are mainly reflected in the following aspects:Clean and smooth engineering hydraulic cylinderLow starting pressure: refers to the low working pressure of a hydraulic cylinder in an unloaded state
