Our structure is simple. Moreover, the seal is easy to manufacture and assemble. One of its remarkable features is its good adaptability to the oscillation and eccentricity of the shaft. The cavity in which it is mounted is compact in size for easy processing. It perfectly overcomes the gap issue caused by the oscillation and rotation of the sealing system when the shaft rotates, and the lip of the oil seal can always be in close contact with the surface of the shaft.
Rubber seals are a common type of basic component in sealing devices, and play a very important role in the contradiction between leakage and sealing. Using rubber seals is an important way to promote technological advancement and prevent and reduce environmental pollution. They are a class of rubber products that are widely used in sealing technology. Because rubber is a polymer material with valuable elasticity, a wide temperature range. It gives less stress in different media producing large deformation, which can provide contact pressure, compensate for leakage gap, and achieve the purpose of sealing.
Our piston seals are designed to provide excellent leak control. We guarantee that it can perfectly meet the user’s requirements for low friction, compactness, precise configuration and simple installation. It is designed for fluid power applications. It is made of compound materials with high performance, which guarantees excellent wear resistance and excellent extrusion resistance for the seal. It is designed to be suitable for almost all fluid media and is highly resistant to oxidation and corrosion. It has excellent dynamic and static sealing performance and can even work under dusty industrial environments. Moreover, it has strong adaptability to various working conditions and can adapt to a fast, high-pressure working environment. At the same time, it has unparalleled performance in extreme temperature environments.
The selection principle of the gasket: according to the working pressure, working temperature, the corrosiveness of the sealing medium and the form of the sealing surface. Temperature influence: In normal temperature and low pressure, use non-metallic soft honey gasket; in medium pressure and high temperature, choose metal and non-metal combination gasket or metal gasket; when temperature and pressure fluctuate greatly, choose good elasticity or self-tightening type Gaskets; in low temperature, corrosive media or vacuum conditions, gaskets with special properties should be considered.
However, hydraulic transmission also has disadvantages compared with mechanical transmission: It is easy to leak and not friendly to the environment. High manufacturing precision is required. Low efficiency. The transmission ratio is not fixed. Due to the special working environment of construction machinery, its hydraulic system has the following characteristics: The working hours are irregular, and sometimes work continuously for a long time. The working environment is outdoors, the working temperature difference is large, and the working environment is dusty. The machine itself walks. Due to the limitation of volume and weight, the hydraulic oil tank is generally relatively small. Due to the volume and weight, the working pressure of the hydraulic system is high, usually above 20MPa, and the highest is about 40Mpa.
