Vertical 40MW Axial Flow Hydro Turbine
Axial Kaplan type Rated power(KW):200~9000
Introduction of axial flow hydro turbine
The runner of the axial flow turbine includes a runner body and blades. The fixed-blade runner blades are fixed on the runner body at a certain angle; the rotating-blade runner is provided with a set of operation and transmission mechanism for rotating the blades in the runner body. The runner body has two types: cylindrical and spherical. The number of runner blades is generally 4 to 6, and small low-head turbines also use 3 blades. The axial-flow paddle turbine has dual adjustment performance, that is, the guide vanes and runner blades can be adjusted, while the fixed-propeller type can only adjust the guide vanes. Therefore, the axial-flow rotary-paddle turbine can maintain the running stability and high efficiency of the turbine within a large range of head and load changes, which is more widely used than the fixed-paddle turbine.
About us
The axial type hydro turbine unit is one of the main hydro turbine products in our company. After more than 20 years of development since 1980s, the axial type hydro turbine unit of our company has been gradually perfected: the covering output ranges from 100kW to 50,000kW and the water head ranges from 3m to 50m. Our company’s axial type hydro turbine units are serviced all over the country and exported to Pakistan, Cuba, Turkey, Vietnam, Mexico and other countries; now, over 50 stations have been generating electricity successfully one after another, receiving a favorable response.
The company has provided 203 sets of axial type unit for 91 hydropower stations, the water head range is 3.5-38m, the maximum unit capacity is 50 MW, the runner diameter is 120cm-580cm, the rotating speed is 78.9rpm-375rpm, and the generator frame is 1.73m-8.2m.
