EuroFlo at CrossRail

pressure gauge ไฮ ด รอ ลิ ค keeps Tunnel boring machine (TBM) cool by a continuous water provide. The Cross Rail venture is an east-west rail route that passes under the town of London utilizing new twin-bore 21km tunnels.
EuroFlo pumps and the tanks are situated at the floor; the water is pumped from there all the method down to the shaft and all alongside the tunnel as a lot as the TBM. Once the water has passed via 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 provides 20 l/s to each TBM and eight l/s is used in the TBM for different works and 12 l/s returns to the tanks. The inlet pressure wanted ranges between four and 10 bar. On one site three TBM’s are operating and the pump system delivers 60 l/s, with the gear consisting of one single tank (3200m3) and one industrial pump used per tunnel. On one other site, the set up support’s the excavation with only one TBM with 20 litres/second and the water storage tank capability of 1100m3
EuroFlo use 37 kW vertical multistage Industrial pumps for the cooling system whereas the TBM excavates through a significant underground section of the Cross rail project.
