Product Name: 20kw Volute Axial Flow Hydro Turbine System/ Hydro Generator Model NO.: ZD760-LM Standard: Nonstandard Speed: High Speed Type: Vertical Hydro Generator Size: Large Turbine Type: Kaplan Trademark: OEM Transport Package: Plywood Case Specification: ISO Origin: China HS Code: 85023900 Product Description There are two types of axial flow turbine: fixed blade propeller turbine and Kaplan turbine. The blades of the fixed blade propeller turbine are fixed, but the structure is simple. When the water flow and output changes, the efficiency of it also changes and the average operation efficiency is lower, therefore fixed blade propeller turbine could be at the power station which the power is not big and the water flow does not change much, currently it is used for the hydraulic head range of 3-30 m.Kaplan turbine has the structure of blade rotation inside, compared with the fixed blade propeller turbines, the blade of it can rotate. According to the different kinds of loads and water flows, the blades and guide vanes coordinate and cooperate with each other and form a certain association league relationship to realize the double adjustment of blades and guide vanes, and to obtain higher hydraulic efficiency and stable operation, and expand the scope of operation efficiency. Therefore, it is suitable for water flow changing greatly, especially for power station with the output changes greatly. It is applicable for the hydraulic head range of 3-30 m and widely used for the power with low water flow and of great capacity.Turbine specificationGenerator specificationstyleDesign water headWith design headDesign speedr/minStylePowerKWRated voltageVRated currentARated speed r/minTransmissionflowl/sPowerKWZD760-LM-60380020545SFW20-6/36820380361000By belt
