The EuroFlo Industrial Pump system retains 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 utilizing 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 along the tunnel as a lot as the TBM. Once the water has handed through the TBM system the remaining water comes again through a filtration system to the tanks on the floor, out of the tunnel.
The water circuit provides 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. เกจวัดแรงดันเชื้อเพลิง needed 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 equipment consisting of one single tank (3200m3) and one industrial pump used per tunnel. On one other site, the set up support’s the excavation with just 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 major underground section of the Cross rail venture.
