EuroFlo at CrossRail

pressure gauge 4 นิ้ว ราคา keeps Tunnel boring machine (TBM) cool by a steady water provide. The Cross Rail project is an east-west rail route that passes under the city of London utilizing new twin-bore 21km tunnels.
EuroFlo pumps and the tanks are located at the surface; the water is pumped from there down to the shaft and all along the tunnel as much as the TBM. Once the water has handed by way of the TBM system the remaining water comes again via a filtration system to the tanks on the floor, out of the tunnel.
The water circuit supplies 20 l/s to each TBM and 8 l/s is used in the TBM for various works and 12 l/s returns to the tanks. The inlet pressure wanted ranges between 4 and 10 bar. On one site three TBM’s are working 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 website, 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 via a significant underground section of the Cross rail venture.
