Must be checked before the pump starts:. A sealing system for all whether the pipe is connected, the system is in working condition. Suction valve should open ISW50-315IA mechanical seal, until the liquid (medium) into the sealed chamber and then open the motor. b. the pump and seal chamber is filled with liquid. c. the sealed chamber Have exhausted air. Especially with the double-end sealing liquid seal, it should be noted drained air. d. Turning examination should feel resistance, but should not have a heavy or wiring. 13, double mechanical seal work ISW50-315IB mechanical seal, isolation seal chamber pressure than the fluid medium pressure high 0.05-0.2MPa. 14, the relevant parameters: mechanical seal installation shaft (or sleeve) to be chamfered at the step 3 × 10 °, and the smooth transition, its roughness Ra≤1.6. Axis (or sleeve) surface roughness Ra≤1.6, runout ≤0.04mm, dimensional tolerances h6. Installation of mechanical seals and sealing cover secondary seal contact area of ??the surface roughness of the stationary ring Ra≤1.6, dimensional tolerances for H8, locating the vertical face of the shaft ≤0.04mm. Mechanical seal work should pay attention to a problem 1. Installation Precautions when. Be very careful not to make ISW50-315IC mechanical seal installation misalignment arising on (1) the gland should be looking for are the coupling, the bolt should be uniform the branch, to prevent the end face deflection gland with feeler points, the error is not greater than 0.05 mm. (2) Check the gland and the shaft or sleeve diameter with the gap (ie, concentricity) mechanical seals, four weeks should be uniform, with a feeler points tolerance is not greater than 0.01 mm. b. spring compression according to the provisions, does not allow too large or too small phenomenon, requiring error 2.00 mm. Excessive face pressure to increase and accelerate wear face. Too small will cause less than the pressure seal and can not play. . c ring is installed, it will ring after the spring should be pressed to automatically bounce mechanical seals | ISW50-315IC mechanical seals | booster (certified merchants) provided by Anguo City Pump Co., Ltd.
