The Acceptance Test of the Model Pump Systerm of Linjiaba Pumping Station in the Eastern Route First-stage Project of the South-to-North Water Transfer Project

This paper was about the test of the pump model system in Linjiaba Pump Station, and it introduced the model, the experimental installation, the testing engines and its precision, and the outcome of the test. The acceptance test performs a series of pick-tests about the pump energy test, the cavitations erosion resistance test and the size of the pump model, and checks the instrument's application and the precision calibration certificate. The results showed that, the efficiency and the cavitation erosion resistance of the model system in Linjiaba Pump Station was superior to that stipulated in the contract. What's more,to make the test comparable interiorly and optimize the flow passage shape,we superadd tests according to related requirements and it makes a satisfactory seat.
