所谓自控自吸泵，就是在启动前不需灌水（安装后第一次启动仍然需灌水），经过短时间运转，靠泵本身的作用，即可以把水吸上来，投入正常工作。250WFB-AD1无密封自吸泵,250WFB-AD2无密封自吸泵,250WFB-AD3无密封自吸泵,250WFB-B无密封自吸泵,250WFB-B1无密封自吸泵,250WFB-B2无密封自吸泵,250WFB-BD无密封自吸泵,250WFB-BD1无密封自吸泵,250WFB-BD2无密封自吸泵,

气液混合式自控自吸泵的工作过程：由于自控自吸泵泵体的特殊结构，水泵停转后，泵体内存有一定量的水，泵再次启动后由于叶轮旋转作用，吸入管路的空气和水充分混合，并被排到气水分离室，气水分离室上部的气体溢出，下部的水返回叶轮，重新和吸入管路的剩余空气混合，直到把泵及吸入管内的气体全部排出，完成自吸，并正常抽水。300WFB-BD1无密封自吸泵,300WFB-BD2无密封自吸泵,300WFB-BD3无密封自吸泵,300WFB-C无密封自吸泵,300WFB-CD无密封自吸泵,300WFB-CD1无密封自吸泵,300WFB-CD2无密封自吸泵,300WFB-CD3无密封自吸泵,300WFB-E无密封自吸泵,300WFB-E1无密封自吸泵,300WFB-E2无密封自吸泵,300WFB-E3无密封自吸泵,
