Abstract: According to the plan design,Liulaojian Station design flow is 80 m3/s. The performance model test device used TJ04-ZL-23 hydraulic model for preliminary design,determined the device performance curve prototype pump,the pumping station lift and flow requirements and deter-mined the various parameters of the prototype pump and motor. By the diversion scheme,the expansive soil treatment and pump device optimization and other factors,determined the prototype pump speed and selected the TJ04-ZL-06 hydraulic model for design. According to the hydraulic loss and critical cavitation allowance,it calculated the installation height,head range from Liulaojian Station and operation time,to ensure the efficient operation of pumping station and the flexibility of flow regulation,the blade hydraulic pressure adjustment mode;engineering characteristics and the actual situation to use elbow inlet conduit,siphon outlet conduit,the vacuum breaking valve flow of the Liulaojian Station,which ultimately deter-mined the structure and the material of the prototype unit main parameters and pump main parts.
