Kaplan & Tubular Turbine

Kaplan Turbine is suitable for medium & low water head and large flow power plants. With same water head, the Kaplan runner speed is higher than that of the Francis'. The Kaplan runner blade can be either fixed and rotatory. The key components include: Kaplan runner, Distributor, Main shaft, Main shaft seal, Turbine guide bearing, Governor, Draft tube, Spiral case.

Product Introduction

1. Advanced CFD, FEA technic is utilized in the designing process to ensure better technical solution.
