There are two types of Axial flow turbine: fixed blade Propeller turbine and adjustable blade 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 3-20 m head.
Propeller turbine Features:
- Compact structure, easy to install.
- Reliable operation, easy to control.
- Efficiency from 80%-91%, good output when flow is stable.
- it can be used at low head and stable big water flow water turbine project.
5kw-50kw Propeller turbine specification
Because different hydro power project head and flow should choose different turbine and different size turbine runner to meet, Turbine specification table can not show all the detail to meet all kind of condition of customer’s project situation, here table only for reference, so please give me your Head and Flow, together with your requirement, we will make the suitable design to meet your need, thanks.
