Machining and Production of Various Parts of Water and Steam Turbines (Water Turbine Nozzle Rings, Steam Turbine Set Including Wheel, Casing, Shaft) and Impeller

Product Introduction:

Water turbine ring nozzle: The ring nozzle is one of the important components in water turbines that are used in power plants; This part is semi-circular and has holes at an angle and with a defined slope for injecting superheated water steam; Also, this part should be made by highly precise machining and in order to perform optimally and increase the efficiency of the turbine, it must be resistant to the environmental conditions of operation, i.e. corrosion caused by the fluid. The diameter of this part is directly related to the power of electricity production and the dimensions of the turbine. The angular machining process is very important and should be taken into consideration in making these parts.

Steam turbine set including Wheel, Casing, Shaft: A steam turbine has various parts, the main ones being Wheel, Casing and Shaft. Casing, Wheel and Shaft are in the form of casting, raw plate and fillet respectively. All parts are made using CNC lathe, 4 and 5-axis CNC milling machine.

Impeller: Impellers and fans with a special blade shape are used in rotating machinery, including blowers, compressors, turbochargers, and also fluid transfer propellers in pipes and channels. The shape, number and angle of the blades, in addition to having a direct effect on the performance of these parts, require complex machining methods and the use of special machine tools such as a 5-axis CNC milling machine.
