摘要
Static-type samplers are required for sampling corrosive, toxic, high-temperature, or radioactive liquid-solid fluids. We have designed a compact reverse flow diverter pumping system for transferring liquid-solid mixtures. In accordance with the Venturi principle, an acceptable volume of liquid-solid fluid is automatically collected into a sampling bottle. The effects of sampling needle sizes, sectional area of the T-section, solid concentration, and liquid viscosity on the performance of fluidic samplers were experi- mentally investigated. The sample volume increased upon the reduction of the sampling needle length and the increase of the sectional area of the T-section, but decreased with the increase of solid concentration and liquid viscosity. Unbiased samples of acceptable volume were produced by the proposed fluidic sampler, even at 10.21 mPa s liquid viscosity, 35 wt% solid concentration, and 6.74 m sampling height.
