Experiment Study on the Drainage Capacity of Special Single Stack Drainage System By Using Instantaneous Flow

摘要

This experiment used instantaneous flow generator drain away water on 34-layer tower.Investigate the different drainage pressure in eachspecial single stack drainage system, explore the relationship between the pressure and flow rate, confirm the corresponding drainage capacity and analyze from multiple perspectivesto.The results show that: the drainage capacity of Sovent system is better than that of DN110mm spiral + strengthening type cyclone system and DN110mm spiral ordinary + ordinary type cyclone system, and the pressure fluctuation of the pipeline system is significantly less than the other two systems;the drainage capacity of the two spiral system is significantly less than the maximum design flow capacity value of building water supply and drainage design specifications (GB50015-2009).
