In the hydraulic system and its system, hydraulic pipe fittings can be used to prevent the leakage of working medium and the intrusion of external dust and foreign objects. Among them, the sealing element is the hydraulic pipe fitting.
External leakage will cause waste of working media, pollute the machine and the environment, and even cause mechanical operation failure and equipment personal accidents; internal leakage will cause a sharp drop in the volumetric efficiency of the hydraulic system, failing to reach the required working pressure, or even work. The tiny dust particles that invade the system will cause or aggravate the wear of the friction pair of the hydraulic components, and further lead to leakage.
Therefore, hydraulic pipe fittings are an important part of hydraulic equipment. The reliability and service life of its work is an important indicator to measure the quality of the hydraulic system.
Except for the gap seal, all hydraulic pipe fittings control the gap between two adjacent coupling surfaces below the minimum gap that the liquid to be sealed can pass through.
