Matters needing attention in the use of mechanical seal equipment
The equipment quality of mechanical seals needs to be very high, because it itself is a kind of oil seal equipment for rotating machinery, it is arranged in a pair or more than a pair of mechanical seal end faces perpendicular to the axis of rotation in the fluid pressure and compensation arrangement of elastic force (or magnetic force). ) and the cooperation of the auxiliary seal, the Grundfos mechanical seal adheres to the relative sliding of the mechanical seal to prevent fluid leakage. Then the precautions for mechanical seal equipment in use are: 1. The radial runout of the imported mechanical seal of the equipment shaft should be ≤ 0.04 mm, and the axial movement amount should not be greater than 0.1 mm; 2. The sealing part of the equipment should be adhered to during the equipment. Clean, the sealing parts should be cleaned, the sealing end face is intact, to prevent impurities and dust from the cartridge mechanical seal from being brought into the sealing part; 3. It is forbidden to bump or strike during the equipment process to prevent the mechanical seal from contacting and damaging and the seal failing. 4. The surface in contact with the seal should be coated with a layer of clean mechanical oil during equipment, so that the equipment can be installed smoothly; 5. When the static ring gland is installed, it is necessary to tighten the screws evenly to ensure that the end face of the static ring and the shaft center The vertical needs of the line; 6. Push the moving ring by hand after the device, so that the moving ring can move flexibly on the shaft, and has a certain elasticity; It is necessary to fill with medium before operation to prevent dry interference and seal failure.
