Abstract:The separation chamber of rotational flow in self-priming pump is an important factor for pump performance.The three-dimensional incompressible turbulent steady rotational flow in self-priming pump was simulated by using standard k-ε model and multiple reference frame model in FLUENT.The interior flow field distribution in the gas-liquid separation chamber was obtained,and its distribution rule was analyzed.A performance forecast model was established,and models with different separation chamber heights were forecasted and contrasted.It was revealed that separation chamber heights have great influence on basic performance.However,its influence on efficiency was little.In order to get the best general performance,there is an optimal separation chamber height under a scheme.By comparing the performance forecast,the optimal value can be estimated.
