Matters needing attention in the use of mechanical seal equipment1

The equipment quality of mechanical seals needs to be very high, because it is a kind of oil sealing equipment for rotating machinery, it is a pair or more than a pair of mechanical seal end faces perpendicular to the rotation axis in the fluid pump mechanical seal pressure and compensation arrangement elastic force ( (or magnetic force) and the cooperation of the auxiliary seal, the adherence and relative sliding are formed to prevent fluid leakage. Then when using the mechanical seal equipment, pay attention to the following: 1. The radial runout of the equipment shaft should be≤0.04 mm, the axial movement of the mechanical seal is not allowed to exceed 0.1 mm; 2. The sealing part of the equipment should be kept clean during the equipment, the sealing parts should be cleaned, and the sealing end face is intact to prevent impurities and dust from being brought into the sealing part; 3 . It is forbidden to hit and hit during the equipment process, so as to prevent the mechanical seal from being damaged due to contact and damage; 4. During equipment, the surface in contact with the seal should be coated with a layer of clean mechanical oil, so that the equipment can be installed smoothly; 5. When installing the static ring gland, it is necessary to tighten the screws evenly to ensure that the end face of the static ring is perpendicular to the axis line; Elasticity; 7. The rotating shaft should be turned by hand after the equipment, and the rotating shaft should not feel heavy; 8. The equipment must be filled with medium before operation to prevent dry interference and seal failure.
