Factory Price Forging Steel Hydro Hydraulic Francis Turbine Runners

Product Description

A Francis turbine is a type of reaction turbine specifically engineered to convert the combined pressure energy and kinetic energy of water into mechanical energy. Unlike its counterpart - the Pelton turbine, which is an impulse turbine suitable for high-head and low-flow applications - the Francis turbine operates efficiently in medium to high-head, medium to high-flow conditions, which are common in most hydropower stations and reservoir projects.

It achieves this by guiding water through a spiral casing (also known as a volute) that evenly distributes the water around the runner, where the water flows radially inward and then axially out, transferring its energy to the runner blades with high efficiency. The runner of a Francis turbine features curved blades that are designed to handle both pressure and velocity changes, making it highly efficient in converting hydraulic energy into rotational mechanical energy.

Francis turbines are primarily designed for vertical axis configurations, although horizontal axis models are also available for smaller installations. Their ability to adapt to a wide range of head and flow conditions makes them the most widely used type of hydropower turbine globally, suitable for applications such as large-scale reservoirs, river dams, and pumped storage hydropower plants, where stable and efficient energy conversion is required.
