机井因水位下降和配套机泵经长期使用技术状态变劣等原因,造成水量大量减少和耗电耗油增加,致使机井装置效率下降,浇地面积减少,灌溉成本增加,经济效益下降。对此采取适当的技术措施后,往往能够增加机井的出水量和降低耗能。具体措施因机井的具体情况而异,现将我们在机井测改中,实践效果较好、简便易行的长轴深井泵调整轴向间隙,加尾巴,降低高出流,调整水泵转速;潜水泵更换粗管径;柴油机降速运行拖动水泵,定时检修机泵等主要技术措施,分别加以介绍。
Due to the decline of the water table and supporting the long-term use of the pump, the technical conditions deteriorate and other reasons, resulting in a substantial reduction in water consumption and power consumption increase, resulting in reduced efficiency of the installation of well machines, irrigated area decreases, irrigation costs increase, economic decline. To take appropriate technical measures, it is often able to increase the output of wells and reduce energy consumption. Specific measures vary with the specific circumstances of the well, now we in the well test, the effect is better, simple and easy long axis deep well pump to adjust the axial clearance, plus tail, reduce the high flow, adjust the pump speed; diving Pump replacement coarse diameter; Deceleration of diesel engine drag the pump, timing maintenance pump and other major technical measures, respectively, to be introduced.
