Installation Guidelines

Pre-Installation Requirements

Perform installation in a dry, dust-free, and clean environment
Ensure sealing chamber and seal components remain completely clean
Apply lubricant or coating to auxiliary sealing surfaces to minimize friction resistance
Use water or soapsuds instead of mineral oil or fat for rubber material seals

Spring Installation Notes

Observe spring coil direction: from back static ring to circle ring
Clockwise shaft rotation requires right-coiled spring
Counter-clockwise shaft rotation requires left-coiled spring
Ensure spring working height reaches specified fixing height per installation diagram

Important: Strictly avoid collision and knocking on seals during installation. Prevent impact on shaft, shaft cover, and sealing cover after installation to maintain seal integrity.

Startup Procedures After Installation

Completely evacuate all air from sealing chamber, especially for double-headed sealing with sealing cement
When restarting machine: open entry valve first, then switch on motor after medium fully enters chamber
For sedimentary mediums: rinse sediment from sealing gland, spring, and linking parts before restart
Manually check rotation shaft resistance for normal and uniform operation before startup
Ensure no blockage or unsmooth operation occurs
Fill hermetic compartment with medium and ensure proper lubrication before machine operation

Critical Warning: Dry friction is strictly forbidden as it may cause damage to air-tightness and seal failure.
