Common material codes for mechanical seals include: C, S, T, and F, which represent different materials.
The function of mechanical seals is to achieve no leakage, no corrosion, no scaling, no wear, no jamming, etc. by selecting different sealing materials and structures under different working conditions and media, so as to ensure the normal operation of mechanical equipment. The following is an explanation of the commonly used mechanical seal material codes:
1. C stands for Silicon Carbide
Silicon Carbide is a ceramic material with excellent thermal conductivity, wear resistance and chemical stability, so it is widely used under high temperature, high pressure and corrosive media.
2. S stands for Carbon/Steel
Carbon/steel sealing surface is a traditional mechanical seal material suitable for working conditions with low temperature and pressure. Due to the different thermal expansion coefficients of carbon and steel, the temperature must be controlled during use to avoid excessive expansion.
3. T stands for Polytetrafluoroethylene
Polytetrafluoroethylene is a very corrosion-resistant material, mainly used for sealing chemical media. It has a very low friction coefficient, so it has good wear resistance and sealing.
4. F stands for Filling
The packing sealing method is to fill the packing materials with different shapes to deform the packing materials, thereby achieving the sealing effect. There are many types of packing materials, and the commonly used ones are graphite, ceramics, metals, etc.
In general, there are many types of mechanical sealing materials. According to different working conditions and media, choosing the right material is the key to ensure the normal operation of the mechanical seal.
