The EuroFlo Industrial Pump system keeps Tunnel boring machine (TBM) cool by a continuous water supply. The Cross Rail venture is an east-west rail route that passes under town of London utilizing new twin-bore 21km tunnels.
EuroFlo pumps and the tanks are located on the surface; the water is pumped from there down to the shaft and all alongside the tunnel up to the TBM. Once the water has handed through the TBM system the remaining water comes again by way of a filtration system to the tanks on the surface, out of the tunnel.
The water circuit offers 20 l/s to each TBM and 8 l/s is used within the TBM for different works and 12 l/s returns to the tanks. เกจวัดแรงดันน้ำราคา wanted ranges between 4 and 10 bar. On one site three TBM’s are operating and the pump system delivers 60 l/s, with the tools consisting of 1 single tank (3200m3) and one industrial pump used per tunnel. On another website, the set up 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 via a serious underground part of the Cross rail venture.
