How to choose suitable Seal factory to supply or fit for your construction machines?
How does mechanical seal work in high temperature environment? How to choose a mechanical seal factory?
For construction machine seal it could be used for hydraulic breaker seal kits, excavators seal kits, wheel loader seal kits, backhoe loader seal kits, crane seal kits for the brand of KOMATSU, CATERPILLAR, VOLVO, HITACHI, DOOSAN, JOHN DEER, CASE, HYUNDAI, NPK, XCMG, SANY, and so on.
Under normal circumstances, the temperature of the medium exceeds 120 °C is considered to be a high temperature seal. In order to ensure the normal operation of the mechanical seal in high temperature environment, we WONEPART will introduce how to keep the mechanical seal working continuously.
First, you should add a cooling flushing device to the machine seal.
Second, choosing the materials that are resistant to high temperature and low temperature, and using different materials depending on the operating temperature in different countries or areas.
The upper limit of the nitrile rubber temperature is 80°C, the silicone rubber and the fluororubber/viton are 200°C, and the teflon is 250°C. In addition, the non-metallic friction pairs in the mechanical seal are mostly made of graphite impregnated materials, so different types of impregnated graphite should be selected according to different working temperature. Generally, the temperature range of the immersed babbitt graphite is less than 150°C, and the temperature of the immersion resin graphite is 170 to 200 °C. The graphite immersed in copper, aluminum and lead can be used under working conditions of less than 400°C. As far as possible, the moving ring assembly should use materials with similar expansion coefficients to prevent the connection between the moving ring and the moving ring seat from loosening at high temperature.
Third, selecting the metal corrugated mechanical seal.
Metal corrugated seals have been used in high temperature seals in recent years and have achieved good results. In this type of construction machine seal, the metal bellows replaces the spring in the ordinary machine seal, eliminating the dynamic ring auxiliary seal ring, and does not need to overcome the friction and wear of the rotating shaft when compensating the moving ring, so it is common used at high temperature and got good results.
We Wonepart (XIAMEN YUDI TECHNOLOGY CO.LTD). was established in 2008 (including its predecessor). After 10 years of intensive cultivation, it has grown into an excellent authorized use of NOK, KAWASAKI, Germany SIMRIT, CORTECO and other world leading brands in China. The company has been rated as an excellent agent by brand. The company's main products are NOK seals, oil seals,piston seal, rod seal, O-rings, Kawasaki hydraulic pumps, hydraulic valves and other imported products.
