The EuroFlo Industrial Pump system retains Tunnel boring machine (TBM) cool by a continuous water provide. เครื่องมือที่ใช้วัดความดันโลหิต is an east-west rail route that passes beneath town of London using new twin-bore 21km tunnels.
EuroFlo pumps and the tanks are located on the floor; the water is pumped from there all the method down to the shaft and all alongside the tunnel up to the TBM. Once เกจ์วัดแรงดันลม has handed by way of 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 8 l/s is used within 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 website three TBM’s are working and the pump system delivers 60 l/s, with the equipment consisting of 1 single tank (3200m3) and one industrial pump used per tunnel. On one other website, 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 through a significant underground section of the Cross rail project.
