| 摘 要： | 微灌自清洗网式过滤器适应大力发展节水灌溉技术的需求。对微灌自清洗网式过滤器分别进行清水和浑水水头损失试验研究,结果表明:在清水条件下,当流量在0~90 m3/h时,自清洗网式过滤器水头损失随流量变化缓慢;当流量在90~240 m3/h时,随着流量的增大,其水头损失增加较快,并确定了不同流量条件下自清洗网式过滤器清洁压降关系式。含砂量一定时,进水流量越大,自清洗网式过滤器局部水头损失越大,过滤周期越短;进水流量一定时,随含砂量的增大,自清洗网式过滤器过滤周期缩短,局部水头损失增加的趋势变大。

| Abstract: | The micro-irrigation self-cleaning screen filter meets the needs of water-saving irrigation technology's development.Research into the head loss of the micro-irrigation self-cleaning screen filter in clean and muddy water conditions,found that in the clean water condition,when the flow rate is in the 0-90 m3/h,the self-cleaning screen filter's head loss changed slowly with the flow;when the flow rate is in the 90-240 m3/h,with the increase of flow,the head loss increased rapidly,identifying the clean pressu... |
