Installation and use of mechanical seal

Installation and use of mechanical seal requirements 1. Must be according to the working condition and a host of suitable type of mechanical seal and material matching, to ensure the normal working of the machine seal and service life. 2. Installation of mechanical seal parts of the shaft ( Collar) The radial runout tolerance should be 0 or less. 4 mm, rotor axial momentum 0 or less. 1mm。 3. Installation of mechanical seal stationary ring sealing end cover ( Or shell) , positioning in the face of axis perpendicularity 0 or less. 04mm。 4. Mechanical seal when installation, must be axis ( Collar) End cover, seal cavity, seal and mechanical seal itself clean, prevent any impurities into the sealing parts. 5. When the temperature of the medium to high, low, or containing impurity particles, inflammable, explosive, toxic, must refer to relevant standards, mechanical seal to take corresponding resistance, irrigation, cooling, screening and other measures. 6. The mechanical seal installation, proper lubrication. According to the product installation instructions, to ensure that the mechanical seal installation size. 7. Equipment must be full of medium before operation, to prevent dry friction and make the seal failure. 8. Sample of single spring mechanical seal, should be spring to reasonable choice, generally, when looking from the stationary ring clockwise for axle steering, choose the right spring. Choose the left spring conversely.
