The application fields of mechanical Seals are very wide, mainly including the following aspects: 

1. Centrifugal pump and mixer: mechanical seal is the most common sealing method in centrifugal pump and mixer. These equipment need to withstand high-speed rotation and strong mixing. Mechanical seal can effectively prevent liquid leakage.

2. Compressor: mechanical seal is also widely used in compressor, such as crankshaft front seal of automobile engine, air compressor, gas compressor, etc.

3. Refrigerator: The application of mechanical seal in the refrigerator can effectively prevent refrigerant leakage and ensure the refrigeration effect and safety performance.

4. Conveying equipment: mechanical seal is also widely used in conveying equipment such as rubber conveyor belt, chain conveyor, screw conveyor, etc., which can prevent liquid and particulate matter from leaking from the conveying equipment.

In a word, mechanical seal is widely used in industrial equipment and is an indispensable part of the sealing of various rotating equipment.
