随着农业机械化程度的不断提高,机电排灌事业迅速发展。为了农业大上快上,早日实现旱涝保丰收,广大农村迫切需要轻巧、高效的农用水泵,以取代笨重、低效的仿苏型泵。在省机械局党委领导下,湖北省机械所与华中工学院组成设计小组,在调查研究的基础上,结合我省特点和动力情况,设计了鄂农4B33型离心泵。在省机械所指导下,鄂农8B13采用了高效率水力模型,在结构上进行了大胆改进,大大缩短了轴向尺寸,改善了受力情况和工
With the continuous improvement of the degree of agricultural mechanization, the electromechanical irrigation and drainage undertaking has developed rapidly. In order to speed up the agricultural industry and realize the harvest of floods and droughts at an early date, the vast rural areas urgently need lightweight, high-efficiency agricultural water pumps to replace bulky, inefficient pumps. Under the leadership of the Provincial Machinery Bureau Party Committee, the Hubei Institute of Machinery and the Huazhong Institute of Technology formed a design team. Based on the investigation and study, combined with the characteristics and power conditions of the province, an E Nong 4B33 centrifugal pump was designed. Under the guidance of the Provincial Institute of Machinery, Eonong 8B13 adopted a high-efficiency hydraulic model, which has undergone bold improvements in structure, greatly reducing the axial size, improving the stress conditions and working conditions.
