Second, the installation and use of the mechanical seal requirements 1. Mechanical seal machine accuracy requirements (to pump mechanical seal for example) (1) radially mounted mechanical seal shaft (or sleeve) maximum runout tolerance not more than 0.04 ~ 0.06mm. (2) axial movement of the rotor does not exceed 0.3mm. (3) locating the seal cavity and seal cap combined face shaft (or sleeve) surface runout tolerance maximum of 0.04 ~ 0.06mm. 2. unanimously confirmed that the seal (1) Make sure the seal is installed with the requirements of the model. (2) carefully before installation and assembly drawing control, the number of parts are complete. (3) and the coil spring transmission of mechanical seals, which have left the spring, right-handed points, subject to the spin axis always choose. 3. The installation method depending on the kind of mechanical seal type, the machine may differ ISG200-315 mechanical seal, but its installation essentials almost identical mechanical seals, installation procedures and precautions are as follows: to determine the installation (1) Installation dimensions shall use the description or sample products to ensure that the mechanical seal dimensions. (2) into the front ISG200-250 mechanical seals, shaft (sleeve), gland should be no burr, bearing in good condition; seals, shaft seal chamber, gland should be cleaned. To reduce friction ISG150-250 mechanical seal, mechanical seal mounted on the shaft parts to be coated with a thin layer of oil to lubricate, taking into account the compatibility with rubber o-ring, if not oil, can be coated with soap and water. Floating mounted with anti-static ring resale without structure, not oiled, should dry loaded gland. (3) The first stationary ring mounted on the shaft and the gland together, be careful not to collide with the shaft, and then into the ring assembly. Spring seat or seat drive set screws should be tightened evenly several times. Until a fixed gland, he pushed compensate for axial compression ring, ring after releasing the compensation can automatically play back cable wiring, then the gland bolts evenly tightened.
