目前,常用的提水灌溉方式有水力提灌、电力提灌和柴油机提灌等。水力提灌机具中水轮泵效率最高。水轮泵提灌不需燃料和电力,而是利用自然的水力能。电力提灌和柴油机提灌消耗的都是常规能源——电力和燃油。这三种提灌哪种灌溉成本低?哪种更节能?这要对具体泵站作具体分析才能得出正确的结论。效率是一项重要的技术经济指标。效率由总体装置效率和机具本身的效率所决定。表1是同一水力资源同一提水站下增速型水轮泵灌和水力发电电灌在设计工况下的效
At present, the commonly used methods of pumping water are hydraulic pumping, electric power pumping and diesel charging. Water lifting equipment in the highest efficiency pump wheel. Instead of using fuel and electricity to lift the water pump, it uses natural hydraulic power. Electricity charging and diesel charging are conventional energy - electricity and fuel. Which of these three kinds of irrigated irrigation is low in cost and which is more energy-efficient? This needs to be analyzed specifically for specific pumping stations to reach the correct conclusion. Efficiency is an important technical and economic indicator. Efficiency is determined by the overall plant efficiency and the efficiency of the implement itself. Table 1 is the same hydropower station with the same pumping station under the speed-up turbine irrigation and hydropower irrigation in the design conditions
