Gear pump installation method with mechanical seal type, the type of machine varies, but its installation essentials are almost the same, the installation steps and precautions are as follows: (1) the installation size to determine the installation, according to the product manual or Sample, to ensure the installation of mechanical seal size. (2) Prior to loading, the shaft (sleeve) and gland should be free from burrs and the bearing is in good condition; the seals, shaft, seal chamber and gland should be clean. In order to reduce the frictional resistance, the shaft should be coated with a thin layer of oil on the mechanical seal to lubricate. Considering the miscibility of rubber O-rings, soapy water should be applied if oil is not suitable. Floating static ring without anti-rotation of the structure should not be oiled, should be dry-loaded gland. (3) Install the static ring and the gland together on the shaft first, be careful not to touch the shaft, then insert the moving ring assembly. Spring seat or drive seat set screws should be evenly tightened several times. Before the gland is not fixed, push the compensation ring by hand for axial compression. After the release, the compensation ring can automatically rebound without jamming, and then the gland bolt is evenly locked.
