It is made up of cast iron or steel plate. To stop the runner in a short time, a small nozzle is providing which directs the jet of water on the back of vanes. This jet of water is called breaking jet. Throughout its length, it has numerous openings at regular intervals to allow the working fluid to impinge on the blades of the runner.
These openings convert the pressure energy of the fluid into momentum energy just before the fluid impinges on the blades. This maintains a constant flow rate despite the fact that numerous openings have been provided for the fluid to enter the blades, as the cross-sectional area of this casing decreases uniformly along the circumference.
It also serves to direct the flow at design angles to the runner blades. These are the centers where the fluid strikes and the tangential force of the impact causes the shaft of the turbine to rotate, producing torque. Close attention in design of blade angles at inlet and outlet is necessary, as these are major parameters affecting power production.
Its primary function is to reduce the velocity of discharged water to minimize the loss of kinetic energy at the outlet. This permits the turbine to be set above the tail water without appreciable drop of available head. You just clipped your first slide!

Proportional or directional valves controlled by the governor operate cylinders that open and close wicket gates or needle valves to adjust the flow of water to the turbine in order to maintain a constant turbine speed.
EXPLAIN GOVERNING OF PELTON TURBINE
What if turbine is running at rated load condition? Do oil pump still suck oil from sump? Recent Updates. We were discussing a new topic, in the subject of fluid mechanics and hydraulics machine, i. Today we will understand here the governing of Pelton turbine or Impulse turbine with the help of this post. So, lets see governing of Pelton turbine. Before going to understand the governing of Pelton turbine, We must recall that hydraulic turbines are basically defined as the hydraulic machines which convert hydraulic energy in to mechanical energy and this mechanical energy will be given to a generator to produce the electric energy.
