The EuroFlo Industrial Pump system keeps Tunnel boring machine (TBM) cool by a continuous water supply. The Cross Rail venture is an east-west rail route that passes under the town of London utilizing new twin-bore 21km tunnels.
เครื่องมือวัดpressure and the tanks are situated at the surface; 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 passed through the TBM system the remaining water comes again by way of a filtration system to the tanks on the surface, out of the tunnel.
The water circuit provides 20 l/s to each 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 web site three TBM’s are working and the pump system delivers 60 l/s, with the equipment consisting of 1 single tank (3200m3) and one industrial pump used per tunnel. On another website, the set up 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 through a significant underground section of the Cross rail project.
