เกจวัดแรงดันเบนซิน keeps Tunnel boring machine (TBM) cool by a steady water provide. The Cross Rail venture is an east-west rail route that passes beneath town of London utilizing new twin-bore 21km tunnels.
EuroFlo pumps and the tanks are situated 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 through the TBM system the remaining water comes back through a filtration system to the tanks on the floor, out of the tunnel.
The water circuit offers 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. The inlet stress wanted ranges between four and 10 bar. On one web site three TBM’s are operating 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 one other website, the set up support’s the excavation with only one TBM with 20 litres/second and the water storage tank capability of 1100m3
EuroFlo use 37 kW vertical multistage Industrial pumps for the cooling system while the TBM excavates via a major underground section of the Cross rail venture.
