摘要(Abstract)：

从可靠性、经济性和维修性等不同角度,分析比较了灯泡贯流泵机组电机开敞式强迫空气冷却-水外冷、密闭式强迫空气循环冷却-水外冷和定子水冷-转子空冷3种典型电机冷却方式的特点。结果表明,开敞式强迫空气冷却-水外冷系统安装维修性及可靠性较好;密闭式强迫空气循环冷却-水外冷电机温升均匀,延长电机绝缘寿命;定子水冷-转子空冷系统冷却费用低、冷却效果好。成果对选用和设计电机冷却系统有一定参考价值。
The three types of motor cooling system of large bulb tubular pump unit,open forced air-cooling and outer water-cooling,closed forced circular air-cooling and outer water-cooling and stator water-cooling and rotor air-cooling,were analyzed and compared from the aspects of the system's safety,economy,maintenance and so on.Results indicate that open forced air-cooling and outer water-cooling system has the best installation,maintainability and reliability,closed forced circular air-cooling and outer water-cooling system makes the motor's temperature rise symmetrically and prolong the motor's insulated life,stator water-cooling and rotor air-cooling system has low cooling expenses and the best cooling effect.The results could provide references to design and select motor cooling system.
