【Abstract】 In this paper, a comprehensive platform of pump with advanced experimental techniques, standard method and qualified apparatus is established. In addition, arithmetic formulae have been analyzed and educed, including lift of pump, shaft power, output power, efficiency of pump, NPSH, installing height and the max installing height. Based on the characteristic parameters from the examination of the pump, a pump characteristic curve is processed. In this way, the paper provides the scientific basis for consumers to choose pump types rationally and economizing energy.更多还原
