| 摘 要： | 研究了一种无机械可动部件、可免维修的脉冲射流取样装置,以甘油-水体系为模拟对象,考察了体系粘度、压冲压力、T型节截面积和降液管长度对其取样性能的影响. 结果表明,随体系粘度从1.21 mPa×s增大到7.38 mPa×s,单次采样量从14.6 mL减小到6.1 mL;随T型节截面积增大单次采样量增大,并随体系粘度变大增大趋势更加显著;当降液管长度从2.65 m减至0.684 m时,单次采样量从19 mL锐减至3.8 mL,压冲压力对采样量几乎没有影响. 降液管中流体不连续流动导致的取样针底部出口处压力显著降低是采样驱动力的来源.

| Abstract: | A pulsed fluidic sampler without moving mechanical components with little maintenance was studied using glycerol-water system as working liquid. The effects of viscosity, static pressure, T-section cross-sectional area and down comer length on sampling performance of the sampler were investigated. The results indicated that the sampling quantity was reduced with increase of system viscosity from 14.6 to 6.1 mL, increased with increase of T-section cross-sectional area and more significant increasing trend w... |
