The EuroFlo Industrial Pump system keeps Tunnel boring machine (TBM) cool by a steady water supply. The Cross Rail challenge is an east-west rail route that passes beneath the town of London utilizing new twin-bore 21km tunnels.
เกจไนโตรเจนsumo and the tanks are positioned on the surface; the water is pumped from there 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 back via a filtration system to the tanks on the surface, out of the tunnel.
The water circuit offers 20 l/s to every TBM and 8 l/s is used in the TBM for various works and 12 l/s returns to the tanks. The inlet strain wanted ranges between 4 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 one other site, the installation 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 while the TBM excavates by way of a major underground section of the Cross rail venture.
