EuroFlo at CrossRail

The EuroFlo Industrial Pump system keeps Tunnel boring machine (TBM) cool by a steady water provide. The Cross Rail challenge is an east-west rail route that passes beneath town of London using new twin-bore 21km tunnels.
EuroFlo pumps and the tanks are located at the surface; the water is pumped from there down to the shaft and all alongside the tunnel up to the TBM. Once pressure gauge digital ราคา has handed through the TBM system the remaining water comes again via a filtration system to the tanks on the surface, out of the tunnel.
The water circuit supplies 20 l/s to every TBM and 8 l/s is used within the TBM for various works and 12 l/s returns to the tanks. The inlet pressure 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 gear consisting of 1 single tank (3200m3) and one industrial pump used per tunnel. On another website, the installation 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 whereas the TBM excavates via a serious underground section of the Cross rail venture.
