BIA common mechanical seal mechanical seal series models: BIA-25, BIA-30, BIA-35, BIA-40, BIA-43, BIA-45, BIA-48, BIA-50, BIA-53, BIA-55, BIA-60, BIA-65, BIA-70, BIA-75, BIA-80, etc., is single spring, rubber bellows, internal flow, non-balanced mechanical seals, springs default rotation is right-handed, the market BIA series on common mechanical seal stationary ring more than 99% of ceramic, metal ring mostly Baptist graphite, the material with a suitable room temperature water, room temperature, low viscosity oils, sewage during the event, including environmental fines and other media clients tend to reflect the effect is not ideal ISG125-250 mechanical seal, the reason for once impurities or particles into the sealing surface of the ceramic to metal 99% graphite is difficult to withstand the test of time, impurities or particulate matter will accelerate seal face wear ISG125-250A mechanical seal, within a very short time BIA mechanical seal will leak, reducing operating efficiency (5), the sealing surface has Trimming: This is due to the sealing surface too far apart, and in the closed fracture. Flash (gasification) is separated from the sealing surface of the more common reasons, especially when the condensate in the hot water system or fluid, water from the expansion of the liquid into a vapor, the sealing surface can be separated. (Cold medium also cause vaporization) mechanical seal sealed metal parts such as springs, fixing screws, transmission parts and metal sets are likely to be a source of seal failure. Spring by alternating stress corrosion is it the most important issue, because the metal will corrode quickly under stress, stainless steel spring susceptible to chloride stress corrosion ISG125-200B mechanical seals, and many of the presence of chlorides in the world So there is the foreign department suggested, do not use stainless steel spring, and is recommended to use a higher corrosion resistance Haast steel springs. In addition, improper assembly spring fatigue is another reason for the failure. Mechanical seals used in fixing screws, do not use the material after hardening to do, because heat will reduce the corrosion resistance of metals, and non-heat treated softer fixing screws can be fastened to the shaft.
