Meaning of Water Pump Mechanical Seal Model

Mechanical seal is a shaft sealing device used in rotating fluid machinery, mainly used to prevent fluid leakage. Its basic structure includes a pair of end faces perpendicular to the axis of rotation, which are kept in contact and slide relative to each other under the action of fluid pressure and the elastic force (or magnetic force) of the compensation mechanism to form a device to prevent fluid leakage. The model of mechanical seal is usually represented by numbers and capital letters of English letters, and each part represents a specific meaning, such as manufacturer, structure type, seal type, journal size and combined material, etc.
