To reduce the cost of wall pump producing,the type and basic parameters of a new series of well pumps were put-forward.
为了降低井泵的生产成本,提出了一个新型系列井泵的型式与基本参数,在结构上采用拉杆把一台泵的所有泵体同时联结起来的形式,代替QJ型系列井用潜水泵和JC型系列长轴深井泵的每个泵体之间分别用螺栓固定联结的型式,同时加大了叶轮直径;在性能指标方面,新型系列井泵的单级扬程比相同井径、相同流量规格的QJ型系列和JC型系列井泵的单级扬程高50%以上,水泵效率高于三个相关标准《井用潜水泵》、《长轴离心深井泵效率》和《离心泵效率》规定的指标。
