在国民经济调整时期,如何采取工程措施,发挥现有水轮泵站效益,节省能源,这是一个很值得大家认真研究的问题。湖南现有水轮泵工程4600多处,装机8000余台。年提水量达10亿立方米。这些水轮泵工程设计灌田264万亩。实际达到的灌溉面积只有177万亩。尚有86万余亩农田因旱减产。主要原因:工程不配套、渠道渗漏大、水轮泵老化、出力低。全省41处灌溉万亩以上的中型水轮泵站有36处未配套成龙,占88％,减少灌溉面积55万多亩。使县苏州河坝设计灌溉面积7万
During the period of national economic restructuring, how to take engineering measures and make full use of the benefits of existing water pump stations to save energy is a question that deserves our careful study. There are more than 4,600 water wheel pump projects in Hunan with more than 8,000 sets installed. Annual water volume of 1 billion cubic meters. 264 million mu of paddy fields are designed for these water pump projects. The actual irrigated area is only 177 mu. There are still more than 860000 acres of farmland due to drought reduction. The main reason: the project is not complete, channel leakage, water pump aging, low output. Thirty-six medium-sized water pump stations with irrigated area of more than 41,000 mu in the whole province have 36 unmatched Jackie Chan, accounting for 88% of the total, reducing the irrigated area by 550,000 mu. So that the county of Suzhou dam design irrigation area of 70,000
