The EuroFlo Industrial Pump system keeps Tunnel boring machine (TBM) cool by a continuous water provide. เกจปรับแรงดันแก๊ส is an east-west rail route that passes underneath the 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 alongside the tunnel as a lot as the TBM. Once the water has handed through the TBM system the remaining water comes back by way of a filtration system to the tanks on the surface, out of the tunnel.
The water circuit supplies 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 pressure needed ranges between four and 10 bar. On one website three TBM’s are working 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 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 part of the Cross rail venture.
