| Abstract: |
| 【Objective】To study the combination uniformity and optimum laying space about the thin wall micro spray belt. 【Method】3 kinds of micro spray belt were choosed which are often used in the saving water engineering.Experiments were carried out on the intensity, uniformity and width of micro-spray belt under different pressures,and the Surfer software Kriging interpolation method of mesh data was used to water volume combination principle about the thin wall micro spray belt with pipe diameter of N44mm, Within the range of 1.0R-2.0R (spraying width), the spraying intensity and uniformity of micro-spraying belt for combination were analyzed, and the optimization spacing of micro-spraying belt for combination was determined. 【Result】The results show that the spraying intensity of single tube micro-spraying belt distribution like single and double peak with the increase of spraying distance, the spraying width increased with the increase of pressure. Besides,the combined spraying intensity decreases with the increase of laying distance and the combination uniformity presents a trend of "large-small-large-small" with the increase of paving spacing, when the paving spacing of micro-spray belt is 1.6R, the combination uniformity reaches its peak. 【Conclusion】The combined spraying intensity is small and the combined uniformity is large which paving spacing is 1.8R and 1.9R, this spacing meets the requirements of the commonly specification use micro spraying belt with pipe diameter of 44mm in the market. |
