额定压力及低压下内镶片式滴头抗堵塞性能试验
Anti-clogging Performance of Dental Labyrinth Emitters under Rated Pressure and Low Operating Pressure
摘要
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. 6 mm, the anti-clogging ability of emitters would be better. However, the design of labyrinth passage section showed more significant effect on the anti-clogging ability of emitters under 0. 04 Mpa operating pressure. Aperture of the filter can select 1/5 of the effective aperture of minimum size of labyrinth passage section under 0. 10 Mpa, and 1/7 of the minimum size of labyrinth passage section under 0.04 Mpa. In addition, the results also showed that intermittent irrigation could contribute to the improvement of anti-clogging performance of emitters under low operating pressure.关键词
