The role and significance of the seal

The role and significance of the seal Abstract: hydraulic systems and system seals to prevent leakage of the working medium outside intrusion from dirt and dust sealing element sealing leakage caused by the working medium machine environment pollution caused by waste machinery accidents caused by malfunctioning equipment volumetric efficiency of the hydraulic system of a sharp decline working pressure not less than required to work into the system caused by tiny dust particles 2002: machine tools, the WTO is a challenge but also opportunities for experts pointed out that China's CNC machine tools to increase research and development efforts to accelerate the development of universal CNC machine tool manufacturing services Rambling Chinese competition in China milling machines and machining centers market situation and outlook abroad lathe level of technology and development direction of the world production of machining centers, needs and developments at home and abroad the world development trend of CNC machine tools trends CNC machining technology and the development of the hydraulic system and their system, the marker cable ties sealing means for preventing leakage of working fluid and the intrusion of dust and foreign matter outside. Wherein the seal element, namely seals. Leakage will result in the waste of the working medium, pollution, machines and the environment, and even cause malfunctioning machinery and equipment, personal accident. Endoleaks volumetric efficiency of the hydraulic system will cause a sharp decline, reach the desired working pressure, can not even work. Intrusion systems tiny dust particles can cause or exacerbate the wear of hydraulic components, and further lead to leakage.

Therefore, Security seals and sealing device is a hydraulic device is an important component. It's the reliability and service life of the hydraulic system is a measure of an important indicator of good or bad. In addition to the gap seals, are the use of seals, so that two adjacent coupling gap between the surface of the liquid to be sealed controlled through the following minimum clearance. In-contact seal is divided into self-sealing compression seals and self-styled self-tight seal (ie lip seal) two kinds.
