The installation of the PTFE gasket varies with the type of mechanical seal and the machine, but the essentials of the installation are the same. The steps and precautions for the installation of the PTFE gasket are as follows: Before the PTFE gasket is installed, the shaft (shaft sleeve) ), the gland has no burrs, and the bearing is in good condition; the seals, shafts, sealing chambers, and glands should be cleaned.

When the graphite packing is tightened and the packing is loaded, each packing ring must be installed in place in sequence until the complete set of packing is completed. This ensures an even distribution of axial stress and reduces friction and leakage rates, reducing or even preventing the need to replace packing or re-tighten glands in the future, thereby extending the service life of the packing set.

Non-asbestos gaskets are roughly divided into non-asbestos rubber sheet gaskets and non-asbestos copy sheet gaskets according to their material, process performance and use. They are made of aramid and other organic fibers and plant fibers, nitrile rubber and minerals. Non-asbestos rubber sheets and non-asbestos gaskets manufactured by rolling or copying process.

The mica board is made by bonding, heating and pressing mica paper and organic silica gel water, in which the mica content is about 90% and the organic silica gel water content is 10%. Excellent flexural strength and processing performance, the product has high flexural strength and excellent toughness, and can be processed into various shapes without delamination by punching. Excellent environmental protection performance, the product does not contain asbestos, and produces less smoke and odor when heated, even smokeless and tasteless.

HDPE sheet and HDPE rod is a highly crystalline, non-polar thermoplastic resin. The appearance of the original HDPE is milky white, and it is translucent to a certain extent in the thin section.

Asbestos packing is mainly used for weak acid and alkali, liquid ammonia, water, oil media, valves and other working conditions. It has the best effect of static sealing and anti-corrosion sealing. Fiber packing has good thermal conductivity, acid and alkali resistance, and is suitable for various solvents. , Gasoline, water, liquid nitrogen medium pump, valve, reaction kettle seal (another good thermal conductivity, acid and alkali resistance, high temperature resistance, suitable for dynamic and static seals under high-speed operation conditions).
