一种泵用底带水冷电机
本技术涉及泵用电机术领域,具体为一种泵用底带水冷电机。
技术介绍
非潜水型的水泵多数采用风冷电机,急速吹过的风经过风叶、电机表面产生不同程度的噪音,风叶转动消耗能源,较差的冷却效果限制了电机的过载能力,使用最广的离心泵因电机过载烧坏的情况发生较多。离心泵的电机负荷在设计扬程左右的较大区间内,随出水量增大而增大,出水量超过设计流量一定范围,电机配套功率余量就会被用尽。出水量再增大电机负荷就会超过电机额定功率,电机温度增高,过高的温度会破坏轴承润滑油油膜导致润滑性能下降,轴承磨损加快,长期持续运转电机温度超过导线绝缘层耐热能力,导线绝缘层加速老化或电机烧坏。许多情况会造成离心泵超大流量,如:扬程余量过大、大而长的出水管空管、出水管爆管、用水量增大、使用环境改变等,若采用加大配套电机功率的方法解决超大流量导致的问题,电机效率会大幅低、成本明显增加。利用水泵出水内冷却电机,解决或改善上述问题不失为一种好的办法,但因采用技术存在诸多弊端得不到推广,具体采用方法及其利弊如下:一种是利用导管将水泵部分出水引入电机外壳夹层,通过导管回流到水泵进口,该方法解决 ...
