根据一机部、省机械局对农用泵改革的意见,我们深入农村进行了广泛地调查研究,我省农村现有的泵型达200多种(实际上大量使用的只有20～30种),型号混乱,性能落后,多是三、四十年代的老产品。给生产、使用、管理带来了很大的困难,造成了比较严重的浪费。我们本着满足农业生产急需和以本省动力配套为主的原则,从省内的条件出发,学习外省的经验,参照国家系列,提出了25种湘农水泵型号,性能见表1。其中离心泵14种(包括自吸泵),混流泵3种,轴流泵5种,潜水电泵3种。在伟大领袖毛主席革命路线的指引下,从一九七一年开始,我们与全省20多个生产厂及有关地,县 According to the opinion of the Ministry of Machinery and Provincial Bureau of Machinery on the reform of agricultural pumps, we carried out extensive investigations and studies in rural areas. There are more than 200 existing pump types in rural areas in our province (in fact, only 20 to 30 are used in large quantities) Model confusion, performance behind, mostly three or four old products. To the production, use, management has brought great difficulties, resulting in a more serious waste. We are in line with the urgent need of agricultural production and the principle of supporting the province’s power-driven principle, starting from the conditions in the province, learn from the experience of other provinces, with reference to the national series, proposed 25 Xiang agricultural pump models, the performance shown in Table 1. Among them, 14 kinds of centrifugal pumps (including self-priming pumps), 3 kinds of mixed-flow pumps, 5 kinds of axial-flow pumps and 3 kinds of submersible electric pumps. Under the guidance of Chairman Mao’s revolutionary line, the great leader, from 1971 onward, we have worked with more than 20 manufacturing plants in the province and relevant prefectures and counties
