前文(见《排灌机械》1982年试刊号)总结了我国农用水泵近三十年来所取得的成绩,提出了发展中存在的问题。因篇幅所限,成绩总结得尚不够全面,又因本人水平不高,对存在问题的分析尚有片面不足之处,因此,本节提出的发展方向其主观片面性仍在所难免,望共同探讨。排灌机械是使用量大、分布面广的一种直接消耗能源的提水机具。从配套动力来看,以1979 The previous article (see Drainage and Irrigation Machinery, 1982 trial issue) summarizes the achievements made by agricultural water pumps in our country over the past 30 years and puts forward the problems in development. Due to limited space, the results are not summed up enough comprehensively, and because of my level is not high, the analysis of the existence of the problem is still one-sided inadequacies, therefore, the development of this section’s subjective one-sided nature is still unavoidable hope to jointly explore .
