There are many types of seals and they are used in various industries. Below we mainly analyze the six major industries in which seals are used.
1. Engineering machinery seals
Construction machinery is an important part of the equipment industry. The seal repair kit generally refers to the sum of all seals and related wearing parts in a specific part of the mechanical equipment. In most mechanical equipment, compared with other mechanical parts, rubber, plastic or other non-metallic materials have a limited service life and high frequency of replacement.
2.Hydraulic / pneumatic seals
China's hydraulic and pneumatic seal industry development process can be roughly divided into three stages. That is: the beginning of the 1950s to the early 1960s was the initial stage; the 1960s to the 1970s was the stage of growth of specialized production systems; the 1980s to the 1990s was the stage of rapid development.
Coaxial seals, such as Stefan / Germany rings, are mostly used in hydraulic cylinders. Its pressure can reach 60MPa or higher; speed can reach 15m / s; operating temperature is between -40C and 200 ° C (determined by the corresponding elastomer material). The seals we produce have been widely used in the hydraulic and pneumatic industries and have been exported to the international market. They have won the trust of our customers.
3.Metallurgical industry seals
Hydraulic technology has largely promoted the realization of automated production processes in the modern metallurgical industry. Different auxiliary equipment in the production process of steel smelting, continuous casting machine and so on are inseparable from the role of the hydraulic system.
Hydraulic equipment has the advantages of easy assembly and lower cost, which is conducive to the improvement of economic efficiency of metallurgical enterprises. It is a more economical and reasonable choice. Therefore, the hydraulic system can be developed and used in a wide range in the metallurgical industry. Therefore, hydraulic seals have played an increasingly important role in the metallurgical industry.
4. Engineering shield mechanical seals
Shield machine is a tunnel excavator. The shield construction method is a support segment for the tunnel to be constructed by the roadheader while digging, which is different from the open construction method. The seal at the articulation of the shield machine is particularly important. Engineering shield mechanical seals are indispensable.
5.Coal mine mechanical seals
Coal mining machinery belongs to a large category of machinery, mainly referring to mining machinery used in the production process of mining, support, transportation, and washing of coal mines. As a big country in coal production, the production of coal mining machinery plays an important role in China. Our drum seals, mountain seals, bud seals, dust seals, etc. are all very important sealing elements in coal mine hydraulic supports!
6. Power equipment seals
Power equipment mainly includes two categories of power generation equipment and power supply equipment. There is a circumferential gap between the shaft and the device. The medium in the device leaks out through this gap. If the pressure inside the device is lower than atmospheric pressure, air leaks into the device. Therefore, there must be a shaft seal device to prevent leakage. There are many types of shaft seals. Because mechanical seals have the advantages of low leakage and long life, mechanical seals are the main shaft seal method in these devices in the world.
