| 摘 要： | 依据ISO短周期滴头堵塞测试方法,测试了12种内镶片式齿型迷宫滴头在额定压力和低压情况下的抗堵塞性能.结果表明:滴头抗堵塞性能随着流道断面最小尺寸增加而提高,当滴头流道断面最小尺寸大于等于0.6 mm时滴头将获得较好的抗堵塞性能,但在0.04 MPa时滴头流道设计形式对滴头抗堵塞性能有更为明显的影响.在过滤器滤网孔径大小选择方面,压力为0.10 MPa时,可选用流道断面最小尺寸的1/5作为有效孔径,而压力为0.04 MPa时,则应按流道最小断面尺寸的1/7来选择.研究还表明,滴灌系统在低压运行时,可通过间歇灌溉的方式来预防和减少滴头的堵塞.

| Abstract: | Based on short term clogging test procedure in ISO clogging test methods for drip emitters,twelve kinds of dental labyrinth emitters were tested for anti-clogging ability under different operating pressures.The results showed that as the minimum size of labyrinth passage section increased,the anti-clogging ability of emitters was improved.When the minimum size of labyrinth passage section was greater than 0.6mm,the anti-clogging ability of emitters would be better.However,the design of labyrinth passage sec... |
