摘  要:
为了研制高扬程、高效率的深井离心泵,以100QJ10型深井离心泵为例,按照L9(34)正交表,选取了叶轮出口安放角、叶轮出口宽度、后盖板直径等因素,每个因素取3个水平,设计出了9个叶轮.通过Fluent提供的标准k-ε湍流模型、SIMPLEC算法、二阶迎风方程,对包含叶轮、导叶在内的2级深井离心泵的全流场进行了数值模拟,获得了9组设计方案在额定工况下的效率、扬程.通过正交试验法分析了各几何参数对效率、扬程的影响规律,并利用极差分析找到了影响深井泵性能的主要因素和次要因素,提出了较优设计方案.样机试验结果表明:较优方案在额定工况下效率为58.41%,单级扬程为5.2 m,扬程与效率都得以大幅提高,满足了设计要求.

摘  要:
In order to develop high head and high efficiency deep-well centrifugal pump,100QJ10 deep-well centrifugal pump was taken as an example.The orthogonal experiment of L9(34),which contains factors with three levels of outlet angle,outlet width,outside diameter of impeller back shroud,etc,was performed to design nine types of impellers.According to standard k-ε model,SIMPLEC algorithm,second-order upwind scheme which were deduced from Fluent,the whole flow field of new type two-stage deep-well centrifugal pump at the operating point was numerically simulated.Nine groups of efficiency and head for design scheme were obtained at rated condition.The effects of geometrical parameters on efficiency and head were discussed by Latin square test method.The primary and secondary factors of the design parameters were acquired by variance analysis.According to the test results,an optimum program for further design was proposed.The test of pump prototype shows that the efficiency of optimal design model pump can reach 58.41% with single-stage head of 5.2 m at rated condition.The improved efficiency and head can meet the design requirements.
