How can you ensure the quality of mechanical seal installation

Must first understand what mechanical seal, it is a kind of rotating machinery seal device, it is in a pair or more than a pair of perpendicular to the axis of the rotating end in fluid pressure and compensation institution stretch ( Or magnetic force) With the cooperation of role and auxiliary seal, keep post merger relative sliding and prevent fluid leakage. So its installation quality requirement is very high, so how are we going to do to ensure the quality of mechanical seal installation of excellent mechanical seal installation note: 1, the shaft radial beat the equipment should be 0 or less. 4 mm, axial momentum not allow greater than zero. 1 mm; 2 sealing parts during the installation, equipment should be kept clean, sealed parts should be clean, the seals are intact, prevent the impurity and dust into the sealing parts; 3, during the installation process strictly forbid a touch attack, knock, lest make pay damage mechanical seal friction and the seal failure; 4, when installed in the sealing contact surface should be coated with a layer of clean machine oil, so as to smooth installation; 5, installing a static ring gland, tighten bolts must force uniform, ensure static ring end face and the axis of vertical requirements; 6, after the installation drive ring with the hand, can make the ring on the shaft flexible mobile, and have certain elasticity; 7, with the hand after installation plate moving axis, axis should be no weight feeling; 8, the equipment must be full of medium before operation, to prevent dry friction and make the seal failure.
