Advanced technology, stable performance and reliable quality
■ Water Head Applicable: H=3m-30m
■ propeller type is with fixed runner, blade angle can not be changed during operation mode
■ Kaplan type is with adjustable runner controlled by oil servomotor and moved according to the load/head change to ensure higher average efficiency
■ Theory of operation
Pelton turbine is widely used with water head of 100M-1000M that is suitable for power station with high head but small water flow. The runner works by being heavily pushed with jet flow that is from injection nozzle through high-pressure pipe. Pelton turbine is regarded as compact structure, stable operation and easy handling.
Water Head Applicable: H=20m-400m.
Used for project with middle & high water head with middle level of water flow.
Divided into vertical type and horizontal type.
Simple structure, reliable operation and widely.
Francis turbines have an output range of 100 kW to 50 MW per unit.
The runners have diameters of up to 2,000 mm.
Hydro turbine governor is the main controller of the hydro turbine. The governor varies water flow through turbine to control its speed or power output. Generating units speed and system frequency may be adjusted by the governor.
Because of apply to computer monitoring system ,automatic control,protection,measurement,telecontrol and video monitoring,it can communicate with cascade dispatching center to compete telemetering,romote signalling,telecontrol and remote regulating,so that realize unattended operation or on duty with less person and safe economical operation for hydropower station.Systmem is composed of power station control layer and local control protective layer,etc.
Hunan Sunny hydropower equipment manufacturing Co., Ltd. was established in November 2004, formerly known as Hunan Xinning hydropower equipment manufacturing plant, which was founded in 1958. It is located in the southwest of Hunan Province, located in Langshan Scenic Area, a beautiful world natural heritage. Covering an area of 130000 square meters, the company is an old professional factory, an international small hydropower production base, and a member of China power generation equipment industry association. It was selected by the Ministry of machinery industry of the people's Republic of China to participate in the Hannover International Exposition in 1981 for its high cost performance. The company has strong technical force and advanced design concept. It can independently design, manufacture and install Francis, impulse, oblique impact, axial flow, tubular and other types of hydraulic turbines with a single capacity of 50MW and below, and the corresponding hydro generators and auxiliary equipment.
