The EuroFlo Industrial Pump system keeps Tunnel boring machine (TBM) cool by a steady water supply. The Cross Rail venture is an east-west rail route that passes underneath town of London using new twin-bore 21km tunnels.
EuroFlo pumps and the tanks are located on the floor; the water is pumped from there all the way down to the shaft and all alongside the tunnel up to the TBM. Once the water has handed through the TBM system the remaining water comes back by way of a filtration system to the tanks on the floor, out of the tunnel.
The water circuit provides 20 l/s to every TBM and eight l/s is used in the TBM for different works and 12 l/s returns to the tanks. เกจวัดแรงดันดิจิตอล wanted ranges between 4 and 10 bar. On one web site three TBM’s are operating and the pump system delivers 60 l/s, with the gear consisting of 1 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 capacity of 1100m3
EuroFlo use 37 kW vertical multistage Industrial pumps for the cooling system whereas the TBM excavates by way of a serious underground part of the Cross rail project.
