水泵一经投入运转，各项性能参数往往达不刻铭牌位，这是由于外界条件的变化，使水系实际运行工况点往往偏离设计最佳工况点．本文根据水泵机组运行生产记录统计数据，对电机和水泵的运行进行了效率和电耗的分析，并探讨了节能措施． Once the water pump is put into operation, the performance parameters often do not engrave the nameplate. This is due to changes in the external conditions, so that the actual operating conditions of the water system often deviate from the design of the best working conditions. In this paper, according to the statistical data of production records of the pump unit, the efficiency and power consumption of the motor and the pump are analyzed, and the energy-saving measures are discussed.
