EuroFlo at CrossRail

The EuroFlo Industrial Pump system retains Tunnel boring machine (TBM) cool by a continuous water supply. The Cross Rail venture is an east-west rail route that passes beneath the city of London using new twin-bore 21km tunnels.
เกจ์วัดแรงดันน้ำมันเครื่อง and the tanks are positioned on the floor; the water is pumped from there all the means down to the shaft and all along the tunnel as a lot as the TBM. Once the water has handed by way of the TBM system the remaining water comes back via a filtration system to the tanks on the floor, out of the tunnel.
The water circuit provides 20 l/s to each TBM and eight l/s is used in 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 website three TBM’s are operating and the pump system delivers 60 l/s, with the tools consisting of one single tank (3200m3) and one industrial pump used per tunnel. On one other website, the installation support’s the excavation with only 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 through a serious underground part of the Cross rail venture.
