Principle of Gland Packing for sealing
Working principle of packing The surface of the shaft is very uneven under microscopic conditions, and it can only partially fit with the packing. So there is a tiny gap between the packing and the shaft, like a maze. The medium is intercepted many times in the labyrinth, so as to achieve the sealing effect. The stuffing seal is installed in the stuffing box by stuffing, and the stuffing is pressed on the surface of the shaft through the stuffing gland. Since the surface of the shaft is always somewhat rough, it can only be partially attached to the filler, but partially not in contact, thus forming countless labyrinths. When the pressurized medium passes through the surface of the shaft, the medium is throttled several times, and the seal is achieved by virtue of this "labyrinth effect". The fit and friction between the filler and the shaft surface are also similar to sliding bearings. There should be enough liquid for lubrication to ensure a certain life of the seal, which is the so-called "bearing effect". It can be seen that a good packing seal is a combination of labyrinth effect and bearing effect.

What is a metal gasket? The role of the gasket
The main function of the gasket is to increase the contact area between the bolt or nut and the surface of the part to prevent the surface of the part from being worn; the second is to make a spring washer to prevent loosening. In addition, it should be noted that the strength and thickness of the gasket have certain requirements.
Is it right to choose expensive non asbestos gaskets?
Expensive gaskets may not be suitable. Non asbestos gasket are made of inorganic fibers or organic fibers mixed with rubber. Different fibers are mixed with different rubbers, and the application conditions are very different.
After the non asbestos gasket is used, there is no defect in appearance, can we still install it and continue to use it?
The use of the gasket is one-time, and professional gasket manufacturers do not recommend secondary use.
