發(fā)布時間:2018-11-08 07:35
【摘要】:增大泥泵最大球形通道可以提升疏浚工程連續(xù)性,減少堵泵的風險,提高疏浚施工效率。泥泵最大球形通道和泥泵效率是泥泵設(shè)計中的矛盾點。針對上述問題通過調(diào)研提出了兩種增大泥泵最大球形通道方案,采用數(shù)值模擬方法計算了3種方案的泥泵內(nèi)部流場。通過對數(shù)值模擬結(jié)果的統(tǒng)計分析,對比3種方案泥泵的性能。確定了增大泥泵最大球形通道葉輪設(shè)計方案,為后續(xù)泥泵改造提供基礎(chǔ)。
[Abstract]:Increasing the maximum spherical channel of mud pump can improve the continuity of dredging project, reduce the risk of blocking pump, and improve the efficiency of dredging construction. The maximum spherical passage of mud pump and the efficiency of mud pump are contradictory points in mud pump design. In view of the above problems, two schemes of increasing the maximum spherical channel of mud pump are proposed, and the internal flow field of three schemes is calculated by numerical simulation. Through the statistical analysis of the numerical simulation results, the performances of the three schemes are compared. The design scheme of the impeller for increasing the maximum spherical passage of the mud pump is determined, which provides the foundation for the subsequent improvement of the mud pump.
