A synchronal rotary multiphase pump is a novel positive-displacement pump which is structurally simple and has a higher
mechanical efficiency. A mathematic model was developed to predict the working performance of the synchronal rotary
multiphase pump when the inlet gas volume fraction of the gas–liquid working fluids varies in the range of 0–0.9. The
pump working process was theoretically analyzed based on the calculated results of pressure, temperature and fluid mass
in the working chamber. The experiment was conducted to test the steady state performance of the synchronal rotary
multiphase pump prototype at different pressure differences and inlet gas volume fractions by using air–oil mixture as the
working fluids. The measured results of temperature difference between the pump inlet and outlet, volume flow rate and
shaft power consumption were shown to be in good agreement with the calculations. The calculated and experimental
results showed that both the volume flow rate and the pump efficiency decreased with the increase of the pressure
difference. When the inlet gas volume fraction increased from 0 up to 0.9, the volume flow rate and the pump efficiency
were decreasing rapidly. It meant that the inlet gas volume fraction had a significant influence on the pump performance. |
