Trouble Shooter For Existing Pipelines

Quanzhou Fengze Dayu Vacuum Water Transporting Technology Co., Ltd.

Air mixing is unavoidable. Remarkable water head or pressure Loss May need secondary pump Discharging height much less than designed level Flow speed lower than designed parameter Full pipe transportation difficult to realize; Cavitation erosion, waterhammer, pipe burst, internal

deposits are common. Hard to maintain capacity, or cope with increased volume

demand.

Molecular Viscosity is not the major reason for energy or pressure loss during liquid piping. Instead, air bulbs inside the pipe lines or pumping systems plays leading role in generating resistance leading to loss of water head (pressure).

Decreasing air mixing and rectify air/liquid flow routes establish VACUUM FLOW which will boost and maintain transport speed at high level.

Unique and world largest siphon vacuum system Vacuum status and rectified flow; Remove air resistance inside pipes, no air discharge

valve is needed. Utilize potential energy to the maximum; Increase speed and volume 20-115% Maintain pipe Filling degree over 99% Pipe wall smoothness no major effect on speed; Avoid pipe crack, cavitation, waterhammer, internal

deposit; Discharging at higher points (30-150%) and transport

longer (40-180%) with less or no energy consumption. Increase existing piping capacity shortly with little

extra investment 4m pipe diameter and limitless line length

Over 100 successful projects in 30 years; Pipe diameter from 300 to 4000 mm; Transportation distance over 100km; Ideal for large scale and long distance water

transportation Overpass 8m rise over original water level Flow faster than gravity or pressurized systems Save money, save power, save pipelines, save time

for clients. Undertake impossible mission.

1. Long Distance Water Transportation

To boost existing pipeline capacity in a short time with small investment No power demand for downward pipeline; Much less power consumption for upward pumping ɸ4m or bigger pipeline and over 100km distance Overpass 8m rise over original water level Flow faster than gravity or pressurized systems

Vacuum flow No air accumulation

2. Tap Water Distribution

Just need one rectifier at the beginning of pipelines; to ensure nonstop water supply to wider area end-

users 4m down the inlet level without secondary pump. to boosts 20-80% supply capacity with Automatic

Response to demand change and 10-40% power saving.

Prolonged lifetime of pipelines by avoiding high pressure, pipe cracking and sludge deposit

No dead corner in the whole supply system Ideal for fire hose

Upper: conventional Lower: vacuum flow can go to higher floors

3. Hydro power application Reduce air mixing Reduce resistance and energy loss Reduce cavitation and water hammer Maintain full filling degree Higher generation efficiency

4. Industrial water, AC water circulation◦ Cooling water is usually circled with pumps. SiphonFlow

can do better with 50-80% of power saving.

5. Deep sea mining 6. Siphoned installation for old and cripple

reservoir to prevent deluge; 7.Automatic irrigation network starting from

the reservoir;

Save power and increase cooling efficiency

Siphoned installation for pumping water during low water level of the reservoir;

Siphoned installation for river closure work; Urban waste water pumping station

modification; Automatic back-filling of underground water; Take and transport water from negative water

head overcoming high obstacles; Siphon expulsion of reservoir sediments with

no power consumption. Mine flood or underground water drainage
