Current situation of technology of pumping station home and the difference with abroad are analysed Summary: Water north is moved south east pumping station of first phase requires the line build 21 pumping station, use and transform 14 Jiangsu to already built pumping station partly, need the large pump that 3.0m of 140 impeller diameter controls about. The main characteristic of these pumping station is lift low, stand-alone flow is large, year run time is long (5000h) , moving dependability demand is high, chosen large pump unit should have advanced maturity, moving efficiency it is tall, good to fight cavitation function, the characteristic with moving reliable stability.

Water north is moved south east pumping station of first phase requires the line build 21 pumping station, use and transform 14 Jiangsu to already built pumping station partly, need the large pump that 3.0m of 140 impeller diameter controls about. The main characteristic of these pumping station is lift low, stand-alone flow is large, year run time is long (5000h) , moving dependability demand is high, chosen large pump unit should have advanced maturity, moving efficiency it is tall, good to fight cavitation function, the characteristic with moving reliable stability.

Water north is moved south east line the lift of pumping station of first phase 2.3 ~ 9.0m, already built the case of large pumping station according to home, can east cent of pumping station of line first phase is 3 lift paragraph will decide basic pump model: 7Appropriate of lift of.0 ~ 9.0m uses pump of mixed flow of type of vertical guide vane; Appropriate of lift of 4 ~ 7.0m uses vertical axial-flow pump; Appropriate of lift of 2.3 ~ 4.0m uses horizontal or inclined axial-flow pump.

Plan to ask according to discharge, major pumping station is 80 ~ 120 discharge, normally stand-alone is controlled in 30 discharge, run reliability to increase unit, want to consider an equipment aircraft normally, accordingly, the number of outfit machine stage of pumping station is 4 ~ commonly 5, it is with should standing in the treasure that build exemple: Total flow 100 discharge, rated head 7.6m, the vertical that chooses stand-alone discharge to be 33 discharge adjusts completely pump of mixed flow of guide vane type, 3 with one equipment, outfit machine 4.

Water north is moved south central line and the line basically is given priority to with do as one pleases on the west, the line wants build east stair of large pumping station sends water. According to not complete count, the marked characteristic of these large pump is: Stand-alone flow is large, ask to be controlled in 30m3/s normally; Lift is low, it is under 10m; Year run time is long, be in 5000 hours commonly / year above; Technical index demand is high, requirement reliability is high at the same time, automation rate is high.
