Mechanical seal components and their associated assembly contact surface, before installation must be cleaned with acetone or anhydrous alcohol. During the installation process should be kept clean, especially moving, stationary ring and auxiliary sealing elements should be free of impurities, dust. Dynamic and static ring surface coated with a layer of clean oil or turbine oil.
　　
Tighten the gland should be corrected after the coupling. Bolt should be tightened evenly, to prevent the gland section deflection, with feeler or special tools to check the points, the error is not greater than 0.05 mm. Check the gland and shaft or sleeve diameter with the mating gap (and concentricity), we must ensure that the surrounding uniform, with a feeler to check the tolerance of each point is not greater than 0.10 mm.
　　
The amount of spring compression to be carried out according to regulations, not allowed to have too large or too small, the required error of ± 2.00 mm, over the General Assembly to increase the section pressure, accelerate section wear. Too small will cause the pressure is insufficient and can not play the role of seal, the spring installed in the spring seat to move flexible. With a single spring to pay attention to the direction of rotation of the spring, the rotation of the spring should be the opposite direction of rotation of the shaft. After the installation of moving ring to maintain flexible movement, the moving ring should be able to automatically spring back after the pressure to the spring.
