The EuroFlo Industrial Pump system keeps Tunnel boring machine (TBM) cool by a continuous water provide. เกจวัดแรง is an east-west rail route that passes underneath the town of London utilizing new twin-bore 21km tunnels.
EuroFlo pumps and the tanks are positioned at the surface; the water is pumped from there right down to the shaft and all alongside the tunnel up to the TBM. Once the water has handed by way of the TBM system the remaining water comes again through 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. The inlet stress needed ranges between four and 10 bar. On one site three TBM’s are operating 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 another website, the set up support’s the excavation with just 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 part of the Cross rail venture.
