Regarding sealing requirements under high-speed, high-pressure, and wide-temperature conditions, my country's scientific research institutes have vigorously carried out research on materials and products. A generalized product layout has been formed to solve the urgent need for hydraulic machines, pneumatic collars, or sealing technology. shortage, product standards continue to improve.
It is understood that metal entangled gaskets, independently developed in China, are excellent-performance sealing materials and products that have been widely used in aerospace, airlines, weapons, ships, packing civilian mechanical engineering and other industries. In the weapons industry Seal seals, anti-friction sleeves, anti-friction sleeves, and high-pressure gas seals are also used in special vehicle transmission devices. Reciprocating seals and anti-electricity recoil sealing materials are still widely used on special ships. Static sealing materials and products have reached a very high level in China. Static sealing uses the space between closed fusion surfaces to achieve the sealing effect. It is based on different materials, different operating temperatures, and different sealing application scenarios. Select, static sealing products include seals of different sizes (O-rings, V-rings and other non-standard bottom seals, seals, etc.), which are mainly used for static sealing of various floor plans. Bore, chamfer seal, circular surface static seal, anti-fouling seal, car window, cabin door seal, etc., have provided high-performance sealing products for a variety of new special weapons, aerospace technology, civilian vehicles, etc. The vulcanization image has a wider temperature range than the product. Among them, the wide-temperature range adhesive types include heat-resistant type, burnout type, high toughness type, low-temperature type, etc., and have the influence of further product development, and can provide various Various O-type, special-shaped sealing rings, gaskets and other sealing products; special rubber has excellent properties such as acid and alkali resistance, high and low temperature resistance, high toughness, high elasticity, etc. The toothed gasket material is technically mature and processed The process is stable and can withstand most gear oils.
