Introduction of Tubular turbine
The Tubular type turbines are usually the best choices for
exploitation of tidal power and hydraulic power with extremely low
heads and extremely large flow rates. They have the advantages such
as large discharge, high flow speed, high efficiency and less
excavation, etc. Their variations have Bulb, Pit, Siphon and S
types according to their structural types.
The water diversion parts, runner and water drainage parts of
Tubular turbine are on one axial line. The water flow directly and
straightly through the runner without spiral casing. The water flow
is axial from the pipe inlet to the draft tube outlet.
Tubular turbine generally has two categories: fully tubular and
half tubular. The half Tubular turbine is divided into bulb, pit
and shaft extension types, etc.
Application scope of heads: 2m~25m
Runner diameters: 1.0m ~ 7.2m
Installable capacity: 200KW ~ 200000KW
We also providing different kinds of water turbine generator:
3.Inclined-jet water turbine
4.Cross flow water turbine
5.Tubular water turbine
Found in 1958, our factory in hydropower products has continuously
been one of the national strategic turbine manufacturers in China
since year 1995. It has now 246,000 square meters ground area and
68,000 square meters office building area. With over 500 workers
and over 200 technicians and engineers, ADDNEW's invested factory
is certificated by ISO9000-2000 and CE.
From the start of 2005 to the end of 2012, ADDNEW and our factory
in Hunan, China have designed, manufactured and installed
successfully over 170 small Hydroelectric Power Stations in
Albania, Chili, Congo, India, Lithuania, Kazakhstan, Vietnam,
Zambia and other overseas markets. The equipments adopted for those
hydropower stations are unit-capacity from 800KW to 100MW and the
total power generating capacities of each station ranging from
1600KW-200MW. All the completed stations are now maintaining their
peak performance after their installations.
Why Choose Us(Addnew)
1.We can provide the complete equipment, including: Water Turbine,
Generators, Inlet Valve, Governor, Computer Control Panel, and
other ancillary equipment.
2.Our production ability and quality of Francis Turbine runner
ranked first in China among all the small and medium sized
3.We have Microcomputer digital speed governor.
4.Our Low voltage (400V) Generator can be controlled by
microcomputer monitor system.( A key to boot, and a key off)
5.Our Microcomputer XCR Excitation Panel is automatic controlled
and can monitor temperature, rotate speed, water level, electric
current, and voltage automatically. If the Microcomputer XCR
Excitation Panel broke down, you can Manual control backup, then,
the machine can run normally before the Microcomputer XCR
Excitation Panel repaired.
