The gas in the mixer using the non-contact type mechanical seal 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 security seals are usually used in vacuum conditions, up to 6bar.
Mechanical seal according to the user part of the liquid lubricated numbered security seals 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 seal 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.
