The EuroFlo Industrial Pump system keeps Tunnel boring machine (TBM) cool by a continuous water supply. ราคาpressuregauge is an east-west rail route that passes beneath town of London utilizing new twin-bore 21km tunnels.
เกจวัดแรงดันลม and the tanks are positioned on the surface; the water is pumped from there all the method 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 again via a filtration system to the tanks on the floor, out of the tunnel.
The water circuit offers 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 stress needed ranges between 4 and 10 bar. On one site three TBM’s are operating and the pump system delivers 60 l/s, with the tools consisting of one single tank (3200m3) and one industrial pump used per tunnel. On another website, 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 while the TBM excavates through a serious underground section of the Cross rail project.
