Rubber gasket is now the most basic and widely used gasket. It is made of synthetic rubber that vulcanized with polymers, added fillers, pigments and various additives. Synthetic rubber has very excellent compressibility and resilience. Only need very little pre tightening force, this rubber can play a role of effective sealing under low temperature low pressure conditions. Rubber gasket is ...
1.Plate rubber bearing: except under special conditions (cold areas), it has basically replaced the commonly used bearings like linoleum cushion, curved steel plate, reinforced concrete pendulum and other forms. The allowable compressive stress of rectangular and circular bearings is 10MPa, which is suitable for Bridges with small spans. It is not suitable to use spherical crown rubber bearings or...
O-ring seals are suitable for installation in a variety of mechanical equipment, which seals in specified temperature, pressure, as well as different liquid and gas medium, in the static or movement state. A large number of various types of sealing components are applied in machine tools, ships, automobiles, aerospace equipment, metallurgical machinery, chemical machinery, engineering machinery, c...
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...
Perfluorinated rubber has three characteristics: First, high temperature resistance; Second, strong corrosion resistance. It has a strong dielectric performance in the acid and alkali environment; And the third is super cleanliness. Those characteristics make it widely used in the following fields: first, chemical processes and petroleum refining. In this field, perfluorinated rubber seals a...
