DESCRIPTION

 

Packing is also called sealing packing, and it is usually woven from softer threads. It is sealed by a strip with a square cross-sectional area in the sealing cavity.

 

Packing seals were originally plugged with fibers such as cotton and hemp in the leakage channel to prevent liquid leakage, and were mainly used as shaft seals for water lifting machinery. Due to the wide source of filler, easy processing, low price, reliable sealing and simple operation, it is still in use today. Now packing is widely used in rotary shaft seals of centrifugal pumps, compressors, vacuum pumps, mixers and ship propellers, piston pumps, reciprocating compressors, reciprocating shaft seals of refrigerators, and rotary seals of various valve stems, etc. .

Packing seal is packed in packing box by packing, and packing is pressed on the surface of shaft by packing gland. Because the surface of the shaft is always rough, it can only partially fit with the filler, and the part is not in contact, thus forming countless labyrinths. When the pressurized medium passes through the shaft surface, the medium is throttled many times, and the seal is achieved by virtue of this "labyrinth effect". The packing and friction of the packing and the shaft surface are also similar to sliding bearings. There should be enough liquid to lubricate to ensure a certain life of the seal, the so-called "bearing effect". This shows that a good packing seal is a combination of the labyrinth effect and the bearing effect.

ADVANTAGE

With the continuous emergence of new materials, there are also great changes in the type of filler structure, which will undoubtedly promote the application of filler seals more widely. The materials used as fillers should have the following characteristics:


There is a certain elastoplasticity. When the packing is axially compressed, it can produce a large radial compression force to obtain a seal; when the machine and the shaft have vibration or the shaft has runout and eccentricity, it can have a certain compensation capacity (followability);


Chemical stability. It is neither corroded, swelled by the medium nor polluted by the medium;


Impermeability. The medium has some penetration into most fibers, so the filler structure is required to be dense. Therefore, when making the filler, it is often necessary to impregnate and fill with various lubricants and fillers;


Good self-lubrication, low friction coefficient and wear resistance;


Temperature resistance. When the friction heats up, it can withstand a certain temperature;


Easy to disassemble;


The manufacturing is simple and the price is low.
