摘要：针对河南省清丰县某井灌区由于机井水位下降而造成机井离心泵无法正常工作的问题,对离心泵进行了全面的检测,并结合该井灌区的相关水文资料以及井、泵的性能参数分析,提出了改造离心泵以改善机井离心泵吸水性能的措施,即利用射流技术改善机井离心泵吸水性能。根据井、泵参数设计了射流装置,通过灌区应用,达到了预期目标,该方案为灌溉设备的改造提供了有效的参考。
We did comprehensive test on centrifugal pump, because water level dropped in a well irrigation area of Qingfeng country in Henan, which made the centrifugal pump working abnormally. The measure for transforming centrifugal pump, which was jet flow technology, to improve suction performance of the shaft centrifugal pump were put forward, after analyzing the related hydrological data of this area and performance parameters of the well and pump. So we designed a fluidic device according to the performance parameters of well and pump, and application reached the expected goal. The scheme provides effective reference for reconstruction of irrigation equipment.
