The choice of drainage pumps and requirements

    Temporary high-pressure fire water system of fire pump should be used with a case,or ues a case ,standby fire pump work ability should not be less than the largest a working fire pump.

    When to use a case should be considered more fire pump in parallel,the superposition of traffic impact on fire pump outlet pressure.

    Selection of fire pump,the pump performance curve should be smooth without hunp,zero flow when the pressure of fire pump should not exceed 140% of the rated pressure system design ,when the pump flow is 150% of the rated flow,the fire pump pressure should not be less than 65% of the rated pressure.

    Fire pump motor shaft power should satisfy the pump flow lift curve of any point on the work requirements.
