节水灌溉技术中离心水泵的选配

节水灌溉机械化技术是通过合理配套灌溉机械设备,根据作物合理水量要求和土壤渗析速度,维持最佳水分输送速度,减少各种水分损失的机械化灌溉技术.因此,它对节约用水、改变农业生产的条件、抵御自然灾害、确保农作物的高产稳产具有十分重要的作用.在节水灌溉机械化技术中,离心水泵是灌溉机械的重要组成部分.为此,介绍了离心水泵的结构、工作原理、选择依据和选择原则,为促进新疆全面实现农业节水灌溉机械化提供了理论依据.

The Selection and Configuration of the Centrifugal Water Pump in the Water Saving and Irrigation Technology

The mechanized technology of water saving and irrigation is the technology which maintains the best water transmission speed and reduces various moisture losing according to the rational irrigation machine configuration, the rational water requirement of the crops and pervasion speed of the soil. Thus, the mechanized technology of water saving and irrigation is very important to water saving, change condition of farm production, resist nature calamities, ensure the high and stabile crops production. In the mechanized technology of water saving and irrigation, the centrifugal water pump is the primary equipment. The paper introduces the structure, the working principle, the option basis and the option principle of the water centrifugal pump. It provides theoretic basis for Xinjiang province to realize the agricultural irrigation mechanization wholly.
