Main Components of Impulse Turbine Pelton Wheel

Main Components of Impulse Turbine Pelton Wheel Points : Main Components of Impulse Turbine Pelton Wheel, Main parts of Impulse Turbine Pelton Wheel The Main Components of Pelton Wheel impulse Turbine are given below:
1. Braking jet or hydraulic brake
2. Wheel or Rotor
3. Buckets or vanes
4. Nozzle
5. Guide mechanism
6. Blades
7. Casing
8. Tail race channel
9. Runner
10. Spear
11. Shaft 1. Braking jet or hydraulic brake When turbines are necessary to be brought to rest, main nozzle is entirely stopped. It has been possessed that runner goes on revolving for a extensive time in such condition before coming to rest in order to bring runner to rest in short stage of time, a hydraulic jet of hydraulic brake is provided. 2. Wheel or Rotor Wheel or rotor is fixed over a shaft as of which the of use power is available. It is a turning part of the turbine on which moving blades are fixed. 3. Buckets or vanes Figure of buckets or vanes are equally set on edge of runner. Current Pelton wheels are double kind buckets. i.e. every bucket is separated into equal pans by a dividing all which is call splitter. It look like to a curved cup or bowl. Jet of water is allowable to strike at centre border of the buckets. 4. Nozzle Nozzle is a way for flow of steam where pressure energy is changed into kinetic energy. Its purpose is to create a jet of steam by a high velocity. 5. Guide Mechanism Guide mechanism reins amount of water passing through nozzle with striking buckets therefore meeting the erratic demand of water. It keeps speed of wheel stable even under variable head. Mechanism consists of a spear fix to end of a shaft which is operated by governor of turbine. 6. Blades In this turbine, just one set of moving blades is firmly fixed to rim of rotor of wheel. It converts the kinetic energy of steam into mechanical work. 7. Casing Casing is outside cover of steam turbine. It is fixed by a fixed nozzle. 8. Tail Race Channel It’s canal and a channel to hold the water after deliver its energy in buckets. This lodge water is discharge through the tail race in channel or river or sent for other reason like irrigation if cropland cists close by. 9. Runner Runner is round disc which is fixing to the horizontal shaft, on the edge of the runner a number of buckets are fixed equally. 10. Spear Spear is a conical needle which is function also by a hand wheel or mechanically in axial direction, depending upon the size of unit. It controls flow by its back with forth motion in nozzle. 11. Shaft Shaft of Pelton wheel is generally horizontal shaft. Two jets might be provided. If 4 to 6 numbers of jets are to be provided then the shaft is usually vertical.
