Sand Mill Seal

Mechanical seal is a device that achieves sealing through mechanical means. It usually consists of sealing rings, packing, sealing gaskets, and sealing casings. The main function of mechanical seals is to prevent liquid or gas leakage between moving parts of mechanical equipment and to prevent foreign impurities from entering the equipment. Mechanical seals are widely used in various industrial equipment such as pumps, compressors, agitators, and centrifuges. They have advantages such as good sealing performance, long service life, and easy maintenance. However, mechanical seals also have some disadvantages, such as generating a large amount of frictional heat, being prone to wear, and requiring regular maintenance. When selecting mechanical seals, factors such as working conditions, media properties, and pressure and temperature requirements need to be considered. Common types of mechanical seals include packing seals, mechanical spring seals, and bellows seals. Different types of mechanical seals are suitable for different working conditions and media types.
