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
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:

1.Francis Turbine Company IntroductionFound 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 enterprises.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.How to inquire our product?1. please send us the detailed parameters of the HPPA Water head----- mB Flow------ m3/s
C Installed capacity--- KW
D Frequency---- 50HZ or 60HZ
E Generator excitation-- static SCR excitation or brushless excitation
Those parameters will decide which type of turbine and generator best satisfy your water condition.
