Mechanical seal rings or faces play a crucial role in mechanical equipment. Mechanical seal is a device used to prevent fluid leakage, typically installed on a rotating shaft to isolate the working medium from the environment. The main components of mechanical seals include dynamic rings, static rings, spring seats, anti rotation pins, push rings, O-rings, etc.
Raw materials in the sealing industry refer to materials that can withstand gap displacement to achieve airtightness and watertightness and are buried in building gaps, referred to as sealing materials.
There are two types of water pump seals, namely packing or mechanical seals. The sealing material is selected according to the actual needs of the working conditions. Generally, packing seals are selected. Common materials include carbon fiber, ramie fiber, and aramid fiber
Each mechanical seal can only function effectively within the specified range. Improper selection will significantly reduce sealing performance, shorten service life, or even cause failure.
The material selection of mechanical seals depends on the specific use conditions and performance requirements. The following are several common mechanical seal materials:
The properties of commonly used materials are as follows:
