摘要:

【目的】探究微灌用泵前微压过滤器的最佳运行工况。【方法】本文以泵前微压过滤器为研究对象，以水头损失、截沙质量和总过滤效率作为考核指标，开展了进水流量、含沙量、分水器型式、滤网面积的物理模型正交试验，采用极差和方差分析方法对试验结果进行处理。【结果】对水头损失影响大小依次排序为:进水流量、含沙量、滤网面积、分水器型式；对截沙质量影响大小依次排序为:含沙量、滤网面积、分水器型式、进水流量；对总过滤效率影响大小依次排序为:滤网面积、含沙量、分水器型式、进水流量。【结论】影响水头损失、截沙质量及总过滤效率的两个主要因素是含沙量和滤网面积；经综合分析可知最佳运行工况为:进水流量4 m3/h，含沙量1.5 g/L，分水器型式3型，滤网面积2060 cm2。

Abstract:

【Objective】The optimal operating conditions of pre-pump micro-pressure filter are explored. 【Method】In this paper, the pre-pump micro-pressure filter was taken as the research object, and the head loss, sand interception quality and total filtration efficiency were taken as the assessment indexes. Orthogonal experiments of the physical model of the inlet flow, sediment content, water separator type, and filter area were conducted. The experimental results were processed by analysis of range, analysis of variance. 【Result】The influences of the factors affecting the muddy water head loss in descending order are inlet flow, the sediment content, filter area, and water separator type. The influences of the factors affecting the trapped sediment mass in descending order are the sediment content, filter area, water separator type, and inlet flow. The influences of the factors affecting the total filtration efficiency in descending order are the filter area, sediment content, water separator type, and inlet flow. 【Conclusion】The two main factors that affect head loss, trapped sediment mass and total filtration efficiency are sediment content and filter area. Comprehensive analysis shows that the best operating conditions are (sediment concentration: 0.36 kg/m3, flow rate: 4 m3/h, water separator type: type 3, and filter area: 2060 cm2).
