China's rising level of sealing material products

For high-speed, high pressure, wide temperature domain under the conditions of sealing requirements, our research institutes and actively carry out relevant research materials and products, the current pattern has formed a series of products to address the hydraulic and pneumatic sealing technology industry need, the rising standards of products.

It is reported that China's self-developed high-performance sealing materials and products, has been in the aerospace, aviation, weapons, ships, machinery industry and other civilian areas has been widely used in the weapons industry, specialty vehicles transmission seal, reducing wear sets, high pressure , stuffed with high-temperature gas tight seal has also been applied, reciprocating seals and sealing materials radiation on the ship is still to get special promotion.

Static sealing materials and products in China has reached a high level. Rely on static sealing closed the gap between the joint surface to achieve the sealing effect, according to different media, different temperature, different sealing applications to choose. Static sealing products including seals of different sizes (O-ring, Y-ring, V-rings and other non-standard gaskets, seals, etc.), mainly used for static sealing surface, lead angle groove seal face , cylindrical static seal, dust seal, vehicle window frames, door seals, etc., has a variety of new special equipment, aerospace technology, commercial vehicles, to provide a high-performance sealing products.

Rubber products, a wide temperature range. Wide temperature domain in which there are varieties of special high-temperature silicone rubber type, ablation resistance, high strength, ultra low temperature, etc., and have further developed the ability to provide a variety of O-shaped seals, gaskets and other sealing products ; special nitrile rubber has oil resistance, high temperature, high strength, high flexibility, excellent performance, the materials technology is mature, the process is stable, resistant to most of the hydraulic oil, machine oil, lubricants, wide temperature range, generally - 50 ℃ ~ 130 ℃, 150 ℃ short time can be resistant to high temperatures, can be used to make working in a variety of oil seals fixed or activities, valve parts and a variety of washers, gaskets, seals and so on. Can provide all kinds of products, and life prediction technology to provide products installed; special fluorosilicone rubber materials and products made of small seals, fuel and fuel vapor in the air medium and long-term operating temperature of -55 ~ 200 ℃, short-term working temperature up to 250 ℃, the naphthalene-based fuel, mineral oil, gear oil and other double-sided media to meet the long-term work -55 ~ 150 ℃, 165 ℃ short-term work requirements.

High-speed rotary sealing products are designed using principles of fluid mechanics fluid power seals. The structure of the sealing and lubrication of the organic unity, reducing the working temperature and friction and wear lip, longer than the similar products doubled. Low-friction formula fluorine rubber seal not only adapt to the fluid power high speed and the use of harsh conditions, but also reduces the processing requirements of the axis, can adapt to 0.25mm or more eccentricity, than the average life expectancy The seal is greatly extended, by the line speed has been 20 ~ 25m / s, pressure 0.01 ~ 0.05MPa, temperature? -40 ~ 180 ℃, 800h stand examination. Provide products in line with national standards and performance evaluation, assessment and other services.

Reciprocating high pressure seal products is a high pressure resistance, wear a combination of low friction sealing system. Working medium pressure increases, the sealing pressure will also increase, thus ensuring a reliable seal under high pressure conditions. High temperature, high pressure gas sealing materials and products, the airtight pad as a key part in special equipment has also been considerable progress in overcoming the shortcomings of the existing gas-tight pad, special equipment can ensure a variety of special conditions in the gas-tight breath pad reliable, adaptable, easy operation, good interchangeability. Anti-corrosive gasket sealing materials are a variety of special devices in the application.
