1.Self priming pump by long-distance transport to reach the use of the site, the installation must be checked before the whole machine parts are intact, fasteners should be tightened to check the pump shaft and motor shaft of the concentric degree, if there is a shift, should be corrected.
2.Installation to try to reduce the hydraulic losses of suction pipe, elbow installed not less than 90 degrees, the import pipeline elbow 90 degrees do not exceed 2, self-priming pump inlet should be set up to prevent impurities from entering the large screen, self suction pump, the pump can ensure the normal operation of the installation, as much as possible, reducing the long road less the import pipeline (which will reduce the air inlet pipeline, thereby reducing the self-priming time, increase work efficiency).
3. Water inlet pipe connecting bolts must be tightened, the seal must be tight, absolutely can not leak, as far as possible the use of soft flange gasket (such as fluorine rubber), otherwise it will seriously affect the self suction pump performance.
