EuroFlo at CrossRail

เกจ์วัดแรงดันลม keeps Tunnel boring machine (TBM) cool by a steady water supply. The Cross Rail project is an east-west rail route that passes under the city of London utilizing new twin-bore 21km tunnels.
เกจวัดแรงดันน้ำดิจิตอล and the tanks are positioned on the surface; the water is pumped from there right down to the shaft and all alongside the tunnel as much as the TBM. Once the water has passed through the TBM system the remaining water comes again through a filtration system to the tanks on the floor, out of the tunnel.
The water circuit supplies 20 l/s to every TBM and 8 l/s is used in the TBM for different works and 12 l/s returns to the tanks. The inlet pressure wanted ranges between 4 and 10 bar. On one web site three TBM’s are working and the pump system delivers 60 l/s, with the equipment consisting of 1 single tank (3200m3) and one industrial pump used per tunnel. On one other web site, the set up support’s the excavation with just one TBM with 20 litres/second and the water storage tank capacity of 1100m3
EuroFlo use 37 kW vertical multistage Industrial pumps for the cooling system whereas the TBM excavates via a significant underground section of the Cross rail venture.
