| 摘 要： | 为探讨单相流量计用于液液两相流参数测量的可行性和有效性,本文对文丘里管、涡轮流量计和椭圆齿轮流量计用于油水两相流测量的响应特性进行了实验研究.文丘里管和涡轮流量计的实验管径为15 mm,25 mm,40 mm,椭圆齿轮流量计的实验管径为25 mm和40 mm.油水两相流总体积流量范围为1～5 m3/h,油含率范围为15%～85%.实验结果表明,文丘里管在高油含率时测得的油水两相流流量比实际流量偏大4%～5%.涡轮流量计的测量误差随油含率升高呈现增大的趋势,最大测量洪差小于5%.椭圆齿轮流量计用于油水两相流测量时相对测量误差小于1.0%且基本不受油含率影响.

| Abstract: | The performance of three Venturi meters, three turbine flowmeters and two oval gear flowmeters for oil-water two-phase flow measurement was investigated experimentally to verify the effectiveness of single-phase flowmeter in liquid-liquid two-phase flow measurement. Experiments for the Venturi meters and the turbine flowmeters were carried out on horizontal pipelines of 15 mm, 25 mm and 40 mm diameters, respectively. Experiments were also conducted for the oval gear fowmeters on horizontal pipelines of 25 m... |
