The EuroFlo Industrial Pump system keeps Tunnel boring machine (TBM) cool by a continuous water supply. เกจวัดแรงดันน้ําไทวัสดุ is an east-west rail route that passes underneath the city of London using new twin-bore 21km tunnels.
EuroFlo pumps and the tanks are located on the floor; the water is pumped from there down to the shaft and all along the tunnel up to the TBM. Once the water has handed by way of the TBM system the remaining water comes back through a filtration system to the tanks on the surface, out of the tunnel.
The water circuit offers 20 l/s to each TBM and eight l/s is used within the TBM for various works and 12 l/s returns to the tanks. The inlet pressure needed ranges between 4 and 10 bar. On one web 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 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 by way of a serious underground section of the Cross rail challenge.
