I believe that everyone must have encountered the oil leakage of the hydraulic cylinder. For the excavator, once the hydraulic cylinder leaks, there will be a phenomenon of slow lifting and insufficient digging force. Let's start this discussion with this
Workers couldn't figure out why the pump shaft seal in their trenching excavator's proportional-valve-controlled hydraulic system would sometimes blow out in cold weather.
Machine and cylinder manufacturers are constantly placing higher value on leak-free hydraulic systems. Regardless of the conditions of use, the demand for longevity is of the installed seals is vital.
Machines operating in harsh environments often encounter wide swings in pressure and temperature shock loads, and sometimes side loads that present major challenges to seals in hydraulic cylinders. This report outlines the challenges of preventing seal le
