机井是我国北方的主要水源工程。全国现有配套机井220万眼,装机2800万马力,井灌面积1.7亿亩,在北方地区的农业生产和农村经济的发展中,发挥着重要作用。但是,在过去机井大发展情况下,由于缺乏技术指导,多数机井没有经过严格的配套设计和选型,加上设备质量不高,供应品种不全和管理不善等原因,造成相当一部分机井设备配套不合理,装置效率低,耗能多,运行成本高,经济效益差。据部分省、市测试资料,现有机井的装置效率大多在20～30%之间,因此,进行机井节能节水技术改造具有重要的现实意义。机井技术改造的步骤:一、测试机井装置效率,主要是测试能源单耗;二、对测试成果进行分析,制定技术改造方案;三、实施技术改造,改造后再测试装置效率,再调整,力争以较少的投资,尽可能提高设备的装置效率。一、机井测试对机井工程、设备进行考核,并针对性地提出技术改
Well is the main source of water in northern China. There are 2.2 million matching wells in the country, with 28 million horsepower installed and a well irrigation area of 170 million mu. It plays an important role in agricultural production and rural economic development in the north. However, due to the lack of technical guidance in the past, due to the lack of technical guidance, most of the shaft wells have not undergone rigorous matching design and selection. Coupled with the low quality of equipment, incomplete supply and mismanagement, etc., a considerable part of the well equipment is not matched Reasonable, low efficiency, energy consumption, high operating costs, poor economic efficiency. According to some provincial and municipal test data, the efficiency of the existing wells is mostly between 20% and 30%. Therefore, it is of great practical significance to carry out energy saving and water saving technological transformation of the well. The steps of technological transformation of the shaft: First, test the efficiency of the well arrangement, mainly test the energy consumption; Second, analyze the test results to formulate technical transformation programs; Third, the implementation of technological transformation, transformation and then test the device efficiency, and then adjust and strive With less investment, equipment installation efficiency as much as possible. First, the well test on the well engineering, equipment assessment, and put forward technical improvements
