The EuroFlo Industrial Pump system keeps Tunnel boring machine (TBM) cool by a continuous water supply. The Cross Rail challenge is an east-west rail route that passes beneath the town of London utilizing new twin-bore 21km tunnels.
EuroFlo pumps and the tanks are situated on the surface; the water is pumped from there right down to the shaft and all alongside the tunnel up to the TBM. Once ร้านซ่อมเครื่องวัดความดันomron has passed by way of 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 supplies 20 l/s to each TBM and 8 l/s is used in the TBM for different works and 12 l/s returns to the tanks. The inlet strain needed ranges between four and 10 bar. On one site three TBM’s are working and the pump system delivers 60 l/s, with the gear consisting of 1 single tank (3200m3) and one industrial pump used per tunnel. On another web site, the set up support’s the excavation with just 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 whereas the TBM excavates via a significant underground section of the Cross rail challenge.
