The packing is also called a sealing packing. It is usually woven from a softer thread and is filled in a sealed cavity by a square or rectangular, round strip to achieve sealing.
The packing seal was firstly plugged with fibers such as cotton and linen in the leakage passage to prevent leakage of the liquid, and was mainly used as a shaft seal for the water lifting machine. Due to the wide source of fillers, easy processing, low price, reliable sealing and simple operation, it is still used today. Packing is now widely used in rotary shaft seals for centrifugal pumps, compressors, vacuum pumps, mixers and marine propellers, piston pumps, reciprocating compressors, reciprocating shaft seals for refrigerators, and rotary seals for various valve stems. .
