Hydraulic design and performance prediction of home methane-sludge pump
In order to deal with the problem of removing the residue fluid and sludge from the methane pit,a home methane-sludge pump was designed.By analyzing the working medium of the sludge pump,the structure mode of flow-passage components was determined and the hydraulic design of the flow-passage components was performed.In the process of impeller hydraulic design a concrete and effective method was given to deal with the situation;where it was impossible to form a smooth flow passage.Its result was checked with three-dimensional modeling so that the rationality of the hydraulic design was guaranteed.The numerical analysis and computation of flow field were performed for different working conditions of the methane-sludge and its the performance was also predicted.
