停机后控制阀打开，破坏了吸入管路中的真空，防止停机后泵腔内液体因虹吸作用而从吸入管路流出，使泵腔内保存足够的液体来完成自吸过程，从而实现“首次引流、永久自吸”。125WFB-A自控自吸泵,125WFB-A1自控自吸泵,125WFB-A1自控自吸泵,125WFB-A2自控自吸泵,125WFB-AD自控自吸泵,125WFB-AD1自控自吸泵,125WFB-B自控自吸泵,125WFB-B1自控自吸泵,125WFB-B1自控自吸泵,125WFB-B2自控自吸泵,125WFB-B3自控自吸泵,125WFB-C自控自吸泵,125WFB-C1自控自吸泵,125WFB-C2自控自吸泵,125WFB-C3自控自吸泵,125WFB-E自控自吸泵,125WFB-E1自控自吸泵,
