The EuroFlo Industrial Pump system keeps Tunnel boring machine (TBM) cool by a steady water supply. The Cross Rail project is an east-west rail route that passes underneath town of London utilizing new twin-bore 21km tunnels.
EuroFlo pumps and the tanks are situated at the surface; the water is pumped from there right down to the shaft and all alongside the tunnel as much as the TBM. Once the water has handed through the TBM system the remaining water comes again via a filtration system to the tanks on the surface, out of the tunnel.
The water circuit provides 20 l/s to every TBM and eight l/s is used in the TBM for various works and 12 l/s returns to the tanks. เกจวัดแรงดันไฟฟ้า needed ranges between 4 and 10 bar. On one website 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 another 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 whereas the TBM excavates through a major underground part of the Cross rail venture.
