近些年来,我省从用户的使用条件和配套动力机的现状出发,将型号杂乱的农用泵简化为25种湘农系列水泵。新泵比老泵效率平均提高4%以上,高者达11%;重量平均降低40%;“三化”水平也有提高,标准件数占总零件数的70%,通用件数占总零件数的80%。并针对农用水泵流动性大、起动频繁的特点,研制了离心自吸水泵,深受用户欢迎。现在,全省已推广新泵20多万台,合150多万马力,已基本上取 In recent years, our province from the user’s conditions of use and supporting the current situation of power machines, the model of agricultural pump is reduced to 25 kinds of agricultural series Xiangnon. The new pump efficiency than the old pump an average of more than 4% increase, the highest up to 11%; average weight reduction of 40%; “Three of ” level also increased, the standard parts accounted for 70% of the total number of parts, common parts the total number of parts Of the 80%. And for the large mobility of agricultural pumps, starting the characteristics of frequent, developed centrifugal self-priming pumps, welcomed by users. Now, the province has promoted more than 200,000 new pumps and a total capacity of more than 1.5 million horsepower
