Abstract
In response to the issues of high head and outdated performance of the original 2.8ZLQ-7.0 water pump at Siyang Second Station,a three-dimensional water pump model was established using CFD finite element software.Internal flow analysis and device performance prediction were conducted under different impeller diameters,flow rates,and blade angles.A reinforcement and renovation scheme using the TJ04-ZL-02 new water pump device was proposed,and internal flow analysis and device performance analysis were conducted under different operating conditions.The study showed that after reducing the rotational speed of the existing water pump device from 150 r/min to 136.4 r/min,increasing the blade angle or enlarging the impeller diameter failed to meet the design requirements for flow rate under the design head condition.With the adoption of the TJ04-ZL-02 water pump,when the impeller diameter was 2,850 mm and the rotational speed was 150 r/min,a higher unit efficiency could be achieved under the design head.If the impeller diameter was increased to 2,950 mm,the rotational speed could be reduced to 136.4 r/min for operation.关键词
