Second, the installation and use of the mechanical seal requirements 1. Mechanical seal machine accuracy requirements (to pump mechanical seal for example) (1) radially mounted mechanical seal shaft (or sleeve) maximum runout tolerance not more than 0.04 ~ 0.06mm. (2) axial movement of the rotor does not exceed 0.3mm. (3) locating the seal cavity and seal cap combined face shaft (or sleeve) surface runout tolerance maximum of 0.04 ~ 0.06mm. 2. unanimously confirmed that the seal (1) Make sure the seal is installed with the requirements of the model. (2) carefully before installation and assembly drawing control, the number of parts are complete. (3) and the coil spring transmission of mechanical seals, which have left the spring, right-handed points, subject to the spin axis always choose. (5), sealing surface trimming: This is due to the sealing surface too far apart, and in the closed fracture. Flash (gasification) is more common sealing surface separate reasons, when condensate ISG65-125A mechanical seals, water from a liquid to a vapor expansion ISG65-160 mechanical seal, can seal particularly in the hot water system or fluid split face. (Cold medium will also cause vaporization) sealed metal parts mechanical seals, such as springs, fixing screws, transmission parts and metal sets are likely to be a source of seal failure. Spring by alternating stress corroded its primary problem, because the metal will quickly under stress corrosion ISG65-125 mechanical seal, stainless steel spring susceptible to chloride stress corrosion, and many of the presence of chlorides world , so there are foreign department suggested, do not use stainless steel springs, and high corrosion resistance are recommended Haast steel springs. In addition, improper assembly spring fatigue is another reason for failure. Mechanical seals used in fixing screws, do not use the material after hardening to do, because heat treatment will reduce the corrosion resistance of metals, and non-heat treated softer fixing screws can be fastened on the shaft.
