EuroFlo at CrossRail

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 beneath town of London utilizing new twin-bore 21km tunnels.
EuroFlo pumps and the tanks are situated on the floor; the water is pumped from there down to the shaft and all along the tunnel as a lot as the TBM. Once pressure gauge ราคา ถูก has passed by way of the TBM system the remaining water comes again by way of a filtration system to the tanks on the floor, out of the tunnel.
The water circuit offers 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 stress needed ranges between four and 10 bar. On one site three TBM’s are operating 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 web 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 while the TBM excavates via a serious underground part of the Cross rail challenge.
