Horizontal Francis turbine above 800kW is suitable for brushless excitation or silicon controlled excitation.We offer horizontal turbine units of 2 fulcrums,3 fulcrums and 4 fulcrums.
Francis turbine is one of the hydro turbines most widely used around the world,and it has merits like steady structure, reliable operation, high efficiency, Francis turbine is suitable for all kinds of large, medium and low water head.The runner is made up of upper crown,lower ring and blades. Its character is that the water inflows along the radium direction, when water flows across the blades of the runner,it outflows along the axial direction.
Francis turbines manufactured by Boland can be used under the circumstance of water head from 15m to 250m, and the diameter of the runner is from 0.35m to 4.5m, installed capacity per unit can vary from 50KW to 50MW roughly.For high water head,Francis Turbine owns low specific speed,for medium water head,it has medium specific speed.As for small water head,it has high specific speed.
