What is packing?

Answered \"Test You 198\": there was a question asking about the degree of coiled rope – I didn’t know what that meant
Ribbon seal is used to seal the pump shaft and prevent leaks
The main purpose of packing is to provide sealing; it can be used on pumps as well as for sealing larger reactors~
The degree specified for the packing is definitely incorrect. Packing, also known as sealing filler, is usually made of relatively soft fibrous materials woven together; strips with a square cross-section are used to fill the sealing chamber, thereby achieving sealing. Packing seals were initially developed by inserting fibers such as cotton and linen into the leakage path to prevent fluid leakage, and they were mainly used as shaft seals for valve shafts. It has been in use to this day due to its wide range of available sources, ease of processing, low cost, reliable sealing, and simple operation. Today, packing is widely used for sealing the shafts of mixers and ship propellers, for shaft sealing in piston pumps and reciprocating pumps, as well as for rotary sealing of valve stems in various valves.
What was said upstairs is very professional; it usually refers to asbestos rope or oil-impregnated asbestos rope
In addition to being used for sealing the shafts of mechanical pumps, packing is also used in oil extraction operations – specifically in the blowout preventer boxes at the tops of pumping wells – as rubber rings that seal the polished rods and prevent crude oil from leaking. This process is referred to by oil workers as \"applying packing\".
The temperature tolerance of packing may refer to the maximum temperature it can withstand.

“The term “pangen” is a transliteration of the English word “packing” and refers to sealing materials.
Packers, also known as sealing fillers, are typically made by weaving together softer fibrous materials; they are inserted into the sealing chamber using strips with a square cross-section in order to achieve sealing. It is mainly used for sealing valves, water pumps, and the shafts of large-scale equipment. It has been in use to this day due to its wide range of available sources, ease of processing, low cost, reliable sealing, and simple operation. With the development of materials science, various types of gaskets suitable for different media have emerged, such as polytetrafluoroethylene.
Nylon rope is a sealing material. Made from softer thread-like materials, it seals the rotating parts of mechanical devices through strips with a square cross-section. Depending on the material and application, they are classified into the following types: Aramid black PTFE interwoven packing SWP801, Aramid packing SWP802, Graphite packing SWP803, PTFE packing SWP804, Carbon fiber packing SWP805, Reinforced PTFE packing SWP806. Packing is also known as sealing filler. It is generally used in valve stems or other applications that require simple sealing. The materials are mostly graphite, PTFE, asbestos, etc. Some of them need to be soaked in oil before use. Graphite packing is widely used by various manufacturers due to its plasticity, slightly better heat resistance compared to other types, as well as its relatively low cost and simple manufacturing process. Asbestos fillers are less common these days, and they are not used in many applications. Additionally: In the past, residential water pipes were often sealed using hemp rope dipped in tung oil; this could be considered a special case of packing material
