The EuroFlo Industrial Pump system keeps Tunnel boring machine (TBM) cool by a continuous water supply. The Cross Rail project is an east-west rail route that passes underneath town of London using 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 along the tunnel up to the TBM. Once เกจวัดแรงลม has handed through the TBM system the remaining water comes back via a filtration system to the tanks on the floor, out of the tunnel.
The water circuit supplies 20 l/s to every TBM and eight l/s is used within the TBM for various works and 12 l/s returns to the tanks. The inlet stress needed ranges between 4 and 10 bar. On one web site three TBM’s are working and the pump system delivers 60 l/s, with the gear 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 part of the Cross rail venture.
