Product Introduction:

Fixed and moving blades are the most important parts of turbines, which have a complex geometry in terms of shape and dimensions. Shroud, airfoil, platform, root and fillets are important parts of a turbine blade. In the turbine, due to the high temperature and speed of the equipment, high stresses are applied to the parts and blades of the turbine. Therefore, these parts are made of special alloys and are balanced with very high accuracy, and are installed on the rotor. Different types of coatings are applied on the parts to protect these parts against special working conditions and also to increase the life of the part. In addition to using geometry, materials and special production methods for this type of parts, a special quality control process is also performed in this regard.

The fixed and moving blades of the turbine, which are installed in its cold section, play a vital role in the operation of the turbine and increase its efficiency, to the extent that the smallest error in the construction or design of these parts causes the loss of turbine efficiency or brings the turbine’s operating conditions closer to the state of surge and instability. Due to the high speed of small turbines, the smallest contact resulting from interference of parts due to surge will cause irreparable damage to the turbine.

Technical Specifications:

In general, the process of making a blade includes the following steps:

* CMM and the production of cloud points and 3D map production

* Material selection through the material analysis of the depreciated sample

* Preparation of raw forged material

* Converting the 3D design to GCODE for sending to CNC machines and blade machining and finally sub-cutting the blades.

* Final quality control of bladesThe main parts of the blade
