The method of installing mechanical seals varies depending on the type of mechanical seal and the type of machine, but the installation methods are almost the same.
1. Determination of installation dimensions: When installing, the installation dimensions of the mechanical seal should be guaranteed according to the product's instruction manual or sample.
2. Before loading, the shaft (sleeve sleeve) and gland should be free of burrs and the bearing condition is good; the seal, shaft, seal chamber and gland should be cleaned. In order to reduce the frictional resistance, the mechanical seal on the shaft should be thinly coated with a layer of oil for lubrication. Considering the compatibility of the rubber O-ring, if it is not suitable, apply soapy water. The floating static ring does not have an anti-rotation pin structure. It should not be oiled. The gland should be installed dry.
3. Install the static ring and the gland on the shaft first, taking care not to touch the shaft, and then load the moving ring assembly. The set screws of the spring seat or the drive base should be tightened evenly several times.
Before the gland is fixed, press the compensation ring for axial compression. After the release, the compensation ring can automatically rebound without jamming, and then the gland bolt is evenly locked.
