The EuroFlo Industrial Pump system retains Tunnel boring machine (TBM) cool by a continuous water provide. The Cross Rail venture is an east-west rail route that passes under town of London using new twin-bore 21km tunnels.
EuroFlo pumps and the tanks are situated on the floor; the water is pumped from there right down to the shaft and all alongside the tunnel as much as the TBM. Once เกจวัดความดันน้ำ has handed via 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 various works and 12 l/s returns to the tanks. The inlet pressure needed 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 another web site, 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 while the TBM excavates by way of a serious underground part of the Cross rail venture.
