Matters needing attention in the use of mechanical seal equipment

Matters needing attention in the use of mechanical seal equipment The quality of mechanical seal equipment needs to be very high, because it itself is an oil seal equipment for rotating machinery, it is on one or more mechanical seal end faces perpendicular to the axis of rotation Under the function of fluid pressure and compensation arrangement elastic force (or magnetic force) and the cooperation of auxiliary sealing, the Grundfos mechanical seal sticks to the relative sliding structure to prevent fluid leakage. Then the precautions for the mechanical seal equipment during use are: 1. The radial runout of the imported mechanical seal of the equipment shaft should be ≤0.04 mm, and the axial runout should not be greater than 0.1 mm; 2. The sealing part of the equipment should be adhered to when the equipment is used. Clean, the sealing parts should be cleaned, the sealing end face is intact, to prevent the impurity and dust of the cartridge mechanical seal from being brought into the sealing part; 3.It is forbidden to hit or hit during the equipment process to prevent the mechanical seal from contacting the damage and sealing failure. ;4. When the equipment is in contact with the seal, a layer of clean mechanical oil should be applied to the surface so that the equipment can be smooth; 5. When the static ring gland of the equipment is tightened, the screw must be evenly stressed to ensure that the end face of the static ring and the shaft center The vertical needs of the line; 6. After the equipment, push the moving ring by hand to make the moving ring move flexibly on the shaft and have a certain degree of flexibility; 7. After the equipment, turn the shaft by hand, and the shaft should have no light or heavy feeling; 8. It is necessary to cover the medium before operation to prevent dry interference and failure of the seal. Keywords: Grundfos mechanical seal, imported mechanical seal, cartridge mechanical seal
