EPDM hoses are generally used as delivery pipes, which is divided into conveying hose and suction hose. Various types of cloth inserted hose are made of different materials according to different transmission medium, with reasonable structural design, good quality and durability. EPDM hose is a flexible hose used for conveying or absorbing (negative pressure condition) various liquids fluids...
The working life of O-ring under dynamic pressure is 5-10 times higher than that of conventional rubber sealing products. Compared with other types of sealing rings, The O-ring has the following advantages: 1.Suitable for both dynamic and static sealing conditions; 2.Suitable for a variety of motion modes: rotary motion, axial reciprocating motion or combined motion (such as rotary reciprocating m...
The leakage of transformer occurs mostly around the gasket, which is mainly caused by the aging and cracking of gasket. The quality of depends mainly on its oil resistance. The poorer oil resistance, the faster aging rate. Especially under high temperature, the aging speed will be faster and easily lead to aging and cracking of gasket, resulting in oil leakage. When overhauling oil-resistant and h...
The cross section of rubber seal gasket is round and has certain self-tightening effect. The sealing effect is better than the flat gasket and the compressive force is smaller. From the aspect of material, the main products of rubber pad: silicone pad, nitrile rubber pad, fluoro rubber pad, other rubber pad. Rubber pads with oil resistance, acid and alkali resistance, cold and heat resistance, agi...
In the process of storage and use of rubber, affect by the environment and human forces, the performance and appearance of rubber changes with time, which is the phenomenon of aging. So what causes rubber to age? There are mainly 7 factors as followed: 1.Oxygen: free radical chain reaction will occur between oxygen and molecules of rubber when molecular chains fracture or over cross linked, which ...
A rubber bushing is a highly elastomer component that can be made from ordinary rubber. The elastic modulus of rubber bushing is small, and the elastic deformation is large after being loaded, so as to absorb impact and vibration. It can be subjected to multiple loads at the same time, but its high temperature and oil resistance is worse than that of steel bushings. The shape of rubber bushi...
