EuroFlo at CrossRail

pressure gauge digital ราคา keeps Tunnel boring machine (TBM) cool by a steady water provide. The Cross Rail challenge is an east-west rail route that passes beneath the town of London using new twin-bore 21km tunnels.
EuroFlo pumps and the tanks are positioned at the floor; the water is pumped from there down to the shaft and all along the tunnel as a lot as the TBM. Once the water has passed by way of the TBM system the remaining water comes back through a filtration system to the tanks on the surface, out of the tunnel.
The water circuit provides 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 four and 10 bar. On one web site three TBM’s are working 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 website, the installation 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 while the TBM excavates by way of a serious underground part of the Cross rail project.
