(5), the sealing surface has a cutting edge: this is due to the sealing surfaces too far apart, and in the closed fracture. Flash (gasification) is separated from the sealing surface of the more common reasons, especially when there is condensate ISW150-200A mechanical seal, the water from the expansion of the liquid into a vapor, the sealing surface can be separated in a hot water system or fluid. (Cold medium also cause vaporization) 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 under stress will quickly corrode ISW150-160B mechanical seals, stainless steel spring susceptible to chloride stress corrosion and chloride in the presence of many of 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 of mechanical seals, because heat will reduce the corrosion resistance of metals, and non-heat treated softer fixing screws can be fastened to the shaft. Third, the choice in the purchase of maintenance seals seals ISW150-250I mechanical seals, most users will sample by size and color to buy, this will only increase the difficulty of procurement, and may not be able to select the right product. The following procedures are recommended to improve the accuracy of purchase seals: 1. the direction of motion - first decide the direction of movement of the location where the seals, such as reciprocating, rotary, screw or fixed. 2. Seal the focus - such as deciding active point is sealed inside diameter rod or piston seal active point is the outer diameter and so on. 3. Temperature rating - from factory machinery for use according to the actual work environment inspection or assessment temperature, determine the required use of materials. Instructions relating to temperature class production users can refer to the following considerations. 4. Size - used by the majority of users will buy the old sample, but the seal in use for some time, will be the temperature, pressure and wear and other factors greatly influence its original size, press select sample only as a reference , a better approach is to measure the location of the seal of the metal tank size, the accuracy will be higher. 5. Pressure Level - Check out the data from the original description of the use of machinery, or by observing the softness of the original seal and structural inference working pressure rating, the relevant pressure levels refer to the following description of the production of user attention.
