The EuroFlo Industrial Pump system keeps Tunnel boring machine (TBM) cool by a continuous water supply. เกจวัดแรงอัดกระบอกสูบ is an east-west rail route that passes under town of London utilizing new twin-bore 21km tunnels.
EuroFlo pumps and the tanks are situated at the surface; the water is pumped from there down to the shaft and all along the tunnel as much as the TBM. Once the water has handed by way of the TBM system the remaining water comes again through a filtration system to the tanks on the surface, out of the tunnel.
The water circuit provides 20 l/s to each TBM and eight l/s is used in 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 another web site, the installation 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 through a serious underground part of the Cross rail challenge.
