Gas-Liquid Flow Through Centrifugal Pumps - Correlation Of Data
MetadataShow full item record
The head capacity characteristics of three different submersible centrifugal pumps were correlated as a function of the gas-to-liquid ratio and pressure at the pump suction. The experimental data were from two independent laboratory investigations. One investigation used air and water as the working fluids, while the second study was conducted using diesel fuel and carbon dioxide with suction pressures up to 400 psig. The results indicated that at low pressures, gas volumes exceeding ten percent began to cause a serious degradation of pump performance. Satisfactory performance was achieved at high gas ratios as the suction pressure was increased.
