No-contact gas lubricated mechanical seals is how to work it

In operation, the gas-lubricated mechanical seal without contact between the sliding surfaces of the two should be a layer of only a few voids Xie meter, in order to produce voids, non-contact type mechanical seal of the two sliding surfaces disengage one another . To achieve this, a three-dimensional ring groove made to ensure that the air is static and dynamic play. Seal in the stuffing box pressure difference generated at the aerostatic effect, while the rotation of the aerodynamic effect. The resulting force balance lift and closed, thereby forming a width of 1 to 5 Xie seal gap.
Applied in the mixer without touching gas lubricated mechanical seals
The gas in the mixer using the non-contact type mechanical truck security seals for the user has three major advantages: 1, no liquid leakage; 2, the product quality is not affected; 3, on the reaction with little or no effect;
Non-contact type mechanical seal also has some other advantages. Include: 1, the operation clean (GMP); 2, low friction loss; 3, the noise does not occur; 4, mechanical wear little or no wear. If the seal system used in the mixer for the above requirements, then such seal member is operable.
Pressure purposes, without contacting mechanical seals are usually used in vacuum conditions, up to 6bar.
Mechanical seal according to the user part of the liquid lubricated seal for many years experience in the use of liquid seal is not used in the past for each of the products are suitable for gas seals. The main factors to consider for sealing products with high sensitivity (eg, sealing surface is touched). To counteract this effect, many types of research and the use of additional components, such as the patented flush mounting flange. When not contact mechanical seal sealing surface when the automatic alignment feature degradation, self-converted to gas consumption, the sealing surface is blown or is rinse. The mounting flange can be used for washing steel container, especially for the enamel container (plastic container). Apart from the gas seal applications beyond the experience gained in the storage and use has also made a series of new insights. When the seal member to achieve its first time of change, and start using the ship between the seal member, may be after many years. Same time, various factors can influence the characteristics of the gas mechanical security seals member. In the assembly accidentally add too much grease or oil - grease or oil into or penetrate into the sealing gap. Then, in use, thereby causing uneven gap, mechanical seal damage. According to experience mechanical seal at its beginning before use should be checked.
