There are usually four types of media:

1. Easy-to-vaporize medium, its request to Sealing Ring is to request conflicting auxiliary materials and sealing chambers with low conflict correlation coefficient and good thermal conductivity. Fluid causes one seal face to freeze. Sealing Ring Manufacturer A shaft sealing device for rotating machinery. Such as centrifugal pumps, centrifuges, reactors and compressors and other equipment. Since the transmission shaft runs through the inside and outside of the equipment, there is a circumferential gap between the shaft and the equipment, through which the medium in the equipment leaks out. If the pressure in the equipment is lower than atmospheric pressure, the air leaks into the equipment, so there must be a Shaft seal to prevent leakage. Mechanical Seals The elastic loading mechanism and auxiliary seal are the mechanical seals of metal bellows, which we call metal bellows seals. In light-duty seals, rubber bellows are also used as auxiliary seals. The rubber bellows have limited elasticity, and generally need to be supplemented by springs to meet the loading elasticity. "Mechanical seal" is often referred to simply as "mechanical seal". The mechanical seal is a device for preventing fluid leakage, which is formed by at least one pair of end faces perpendicular to the rotation axis, which keep fit and relatively slide under the action of fluid pressure and the elastic force (or magnetic force) of the compensation mechanism and the cooperation of the auxiliary seal.

2. High-viscosity medium, which requires the sealing ring to be a conflicting auxiliary material, wear-resistant, and the spring must have enough ability to overcome the resistance of the high-viscosity medium to avoid the temperature of the sealing chamber being too low and causing the medium viscosity to be too high, requiring the sealing chamber to be used for heat preservation or heated.

3. The medium containing solid particles has wear resistance to the conflict pair of the sealing ring, and should be able to eliminate solid particles or avoid solid particle deposition.

4. The gas passes through the medium, which has low porosity, conflicting auxiliary materials and wear resistance to the graphite impregnated sealing ring of the sealing ring; the sealing ring has good floatability, especially it can be used to control the sealing of mixing technology equipment; it is used to manage the vacuum system When sealing, pay attention to the leakage of some external ambient air, and pay attention to the directionality of the sealing.

In practical applications, sealing rings can be selected according to the characteristics of the above-mentioned media.
