EuroFlo at CrossRail

The EuroFlo Industrial Pump system retains Tunnel boring machine (TBM) cool by a continuous water provide. The Cross Rail project 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 positioned at the floor; the water is pumped from there all the way down to the shaft and all along the tunnel up to the TBM. Once the water has passed by way of the TBM system the remaining water comes back via a filtration system to the tanks on the surface, out of the tunnel.
The water circuit supplies 20 l/s to each TBM and eight l/s is used within the TBM for different works and 12 l/s returns to the tanks. ราคาเกจวัดแรงดันลม wanted ranges between 4 and 10 bar. On one website three TBM’s are working and the pump system delivers 60 l/s, with the tools consisting of 1 single tank (3200m3) and one industrial pump used per tunnel. On one other web site, the installation support’s the excavation with only 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 major underground part of the Cross rail venture.
