摘要 膜片的可变性是压力补偿灌水器实现高压条件下稳定出流的主要因素,膜片的特征参数及与灌水器壳体的相互配合直接影响灌水器的整体性能.以PLASTRO 公司生产的Supertif-03120-0003型管上式压力补偿灌水器为原型件,借助(3DP)快速成型技术制作管上式灌水器试验件,选取硅橡胶材质的弹性膜片,对膜片的厚度、硬度进行单因素分析和正交试验,研究弹性膜片不同特征参数对灌水器水力性能的影响.经过多重比较分析得出,灌水器水力性能与弹性膜片特征参数之间的定性关系,为压力补偿灌水器的优质膜片材料的研发提供依据.本试验结果表明:低流态指数最优组合为A3B4,即弹性膜片的厚度为2.0 mm,邵氏硬度为60.

Abstract: The variability of the diaphragm is the main factor for the pressure compensation emitter to achieve stable outflow under high pressure conditions. The characteristic parameters of the diaphragm and the interaction with the emitter housing will directly affect the overall performance of the emitter. In this paper, Supertif-03120-0003 pressure compensating emitter on the pipe manufactured by PLASTRO was used as the prototype, and the on-tube type water emitter test piece was fabricated with the help of(3DP)rapid prototyping technology and selecting silicone rubber elastic diaphragm. Through single factor and orthogonal test, the influence of different parameters of elastic diaphragm on the hydraulic performance of the emitter was studied. The relationship between the hydraulic performance of the emitter and the characteristic parameters of the elastic diaphragm was obtained via multiple comparison analysis. The result of this research shows that the optimal combination of low flow index is A3B4 when the thickness of diaphragm is 2.0 mm and the hardness is 60.
