Mechanical seal is by a pair or number of the relative to the shaft perpendicular to the sliding surface of the end of the fluid pressure and the compensation mechanism to maintain the role of elastic (or magnetic force) and fitted with auxiliary seal to achieve the leakage of the shaft Seal device. Now to introduce the pump mechanical seal installation methods and precautions. Pump mechanical seal Mechanical seal installation method and precautions 1) The radial runout of equipment shaft should be ≤ 0.04 mm, the axial play does not allow more than 0.1 mm; 2) The sealing parts of the equipment should be kept clean during installation, sealing parts Should be cleaned, sealed end face intact, to prevent impurities and dust into the sealing parts; 3) In the installation process is strictly prohibited to hit, beat, so as not to pay mechanical seal friction damage and seal failure; 4) When installed in contact with the seal The surface should be coated with a clean machine oil, so that it can be successfully installed; 5) When installing the static ring gland, tighten the screws must be force evenly to ensure the static ring end and the axis of the vertical requirements; 6) Push the moving ring, make the movable ring move flexibly on the shaft, and have a certain flexibility; 7) After installation, use the handwheel to rotate the shaft, the shaft should have no heavy feeling; 8) The equipment must be filled with medium before operation to prevent dry friction So that the seal failure; 9) easy to crystallization, granular media, the medium temperature> 80oC, should take the appropriate flushing, filtration, cooling measures, a variety of auxiliary devices, please refer to the relevant standards of mechanical seals. 10) When installing, contact the surface of the seal should be coated with a clean mechanical oil, pay special attention to the choice of mechanical oil for different auxiliary sealing material, to avoid causing O-ring oil expansion or accelerated aging, resulting in seal failure in advance .
