中文摘要: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 0.6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.

Transactions of the Chinese Society for Agriculture Machinery (CSAM), in charged of China Association for Science and Technology (CAST), sponsored by CSAM and Chinese Academy of Agricultural Mechanization Science(CAAMS), started publication in 1957. It is the earliest interdisciplinary journal in Chinese which combines agricultural and engineering. It always closely grasps the development direction of agriculture engineering disciplines and the published papers represent the highest academic level of agriculture engineering in China. Currently, nearly 8,000 papers have been already published. There are around 3,000 papers contributed to the journal each year, but only around 600 of them will be accepted. Transactions of CSAM focuses on a wide range of agricultural machinery, irrigation, electronics, robotics, agro-products engineering, biological energy, agricultural structures and environment and more. Subjects in Transactions of the CSAM have been embodied by many internationally well-known index systems, such as: EI Compendex, CA, CSA, etc.
