How to ensure the installation quality of mechanical seals

How to ensure the installation quality of mechanical seals must first find out what mechanical seals are, in fact, it is an oil sealing device for rotating machinery, which is in a pair or more than a pair of end faces perpendicular to the axis of rotation in the fluid pressure and compensation mechanism Under the action of elastic force (or magnetic force) and the cooperation of the auxiliary seal, the mechanical seal is kept in close contact and relatively sliding to prevent fluid leakage. Therefore, the installation quality requirements are very high, so what should we do to ensure the excellent installation quality of mechanical seals? Mechanical seal installation notes: 1. The radial runout of the equipment shaft should be ≤0.04 mm, and the axial mechanical seal movement It is not allowed to be larger than 0.1 mm; 2. The sealing part of the equipment should be kept clean during installation, and the sealing parts should be cleaned, and the sealing end surface should be intact to prevent impurities and dust from being brought into the sealing part; 3. It is strictly forbidden to knock or knock during the installation process , So as not to damage the mechanical seal due to friction and damage the seal; 4. During installation, a layer of clean mechanical oil should be applied to the surface in contact with the seal so that it can be installed smoothly; 5. When installing the static ring gland, the tightening of the screw must be affected. The force is uniform to ensure the vertical requirements of the end face of the static ring and the axis line; 6. After installation, the moving ring can be pushed by hand to make the moving ring move flexibly on the shaft with a certain degree of flexibility; 7. After installation, turn the shaft by hand. The shaft should not feel light or heavy; 8. The equipment must be filled with medium before operation to prevent dry friction and seal failure. Keywords: mechanical seals, mechanical seals
