高原地区给水水泵与电机选型设计

Selection and Design for Water Supply Pump and Electric Motor in Plateau Area

在高原地区选择水泵时,需要根据当地的环境条件对水泵的参数进行修正,才能保证水泵的安全运行。高原地区大气压强低,对水泵吸上真空高度有显著的影响,为了保证不产生气蚀,泵房最好采用正进水形式。高原气候对电机的功率、绝缘、温升等有显著影响,电机需要降容使用。

In order to ensure the safty operation of the pumps in plateau sections,it is necessary to adjust the operational parameters of the pump according to the local environmental conditions. The low atmospheric pressure in plateau area has a significant influence on suction vacuum height of the pump. The inflow should be introduced from the forward direction to avoid the cavitation. The climate in plateau section also has a remarkable influence on motor power,insulation,temperature rise and so on,and the capacitance of motors needs to be reduced for application.
