Installation Use Requirements :
- The radial runout of the equipment shaft should not exceed 0.04 mm, with axial runout not exceeding 0.1 mm;
- The sealing cavity areas of the equipment should be kept clean during installation, and sealing components must be thoroughly cleaned. Ensure that the sealing end faces remain intact to prevent contaminants and dust from entering the sealing area.
- During installation, avoid any contact or tapping to prevent damaging the mechanical seal through friction, which could lead to sealing failure.
- During installation, apply a layer of clean machine oil to the surfaces that will come into contact with the seal, ensuring smooth installation.
- When installing the stationary ring gland, tighten the screws evenly to ensure the stationary ring face is perpendicular to the shaft centerline.
- After installation, gently push the moving ring by hand to ensure it moves freely along the shaft while maintaining some elasticity.
- After installation, manually rotate the shaft—there should be no sensation of unevenness or heaviness.
- Before starting operation, the equipment must be fully charged with the medium to prevent dry friction, which could lead to seal failure.
