What Is a Pelton Wheel?

Pelton turbine (also: Pelton wheel or Pelton Turbine, English: Pelton wheel or Pelton Turbine) is a kind of impact turbine, it was invented by the American inventor Lester in the 1870s Developed by Alan Pelton. The Pelton-type water turbine is used to obtain energy when water flows and hits the waterwheel, which is different from the traditional upper-fired waterwheel driven by the weight of water. Even before Pelton's design was published, a number of different impact turbine versions existed. However, their working efficiency is lower than that of Pelton's design. After the water leaves the waterwheel, the water usually still has speed, and a lot of kinetic energy of the waterwheel is wasted together. Pelton's paddling geometric design allows the moving wheel to run at half the speed of the water jet, leaving the moving wheel at a very low speed; therefore, the design of Pelton almost completely captures the impact energy of water, so that it can Owning a high-performance turbine.

After the high-speed water flows into the pipeline, the powerful water column is driven through the needle valve to the bucket-shaped fan blade on the moving wheel to drive the moving wheel. This is also referred to as the impact fan blades, which surround the periphery of the driving wheel and are generally called the moving wheel. (See photo, vintage Pelton turbine for details). Since the water jet impinges on the fan blades, the flow direction of the water will change due to the shape of the bucket. The force of the water impact will exert a torque on the water bucket and the moving wheel system, and use this to rotate the moving wheel; the flow direction of the water flow is "irreversible", and the water outlet is set outside the water bucket, at which time the flow velocity will be reduced to Very low speed. In this process, the momentum of the fluid jet will be transferred to the moving wheel and from there to the water turbine. therefore"
