The EuroFlo Industrial Pump system retains Tunnel boring machine (TBM) cool by a continuous water provide. The Cross Rail venture is an east-west rail route that passes underneath the town of London using new twin-bore 21km tunnels.
EuroFlo pumps and the tanks are located at the floor; the water is pumped from there down to the shaft and all alongside the tunnel as much as the TBM. Once เกจวัดแรงดันไนโตรเจนราคา has handed through the TBM system the remaining water comes back 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 eight l/s is used within the TBM for different works and 12 l/s returns to the tanks. The inlet strain wanted ranges between 4 and 10 bar. On one site three TBM’s are working 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 web site, 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 whereas the TBM excavates through a significant underground part of the Cross rail challenge.
