EuroFlo at CrossRail

เกจวัดแรงดันน้ำประปาราคา retains Tunnel boring machine (TBM) cool by a steady water provide. The Cross Rail challenge is an east-west rail route that passes under the city of London utilizing 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 a lot as the TBM. Once the water has handed by way of the TBM system the remaining water comes again through 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 in the TBM for different works and 12 l/s returns to the tanks. The inlet pressure 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 one other web site, 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 challenge.
