Question: What exactly are the fully three-dimensional turbine blades?
Thread Content
Our company plans to retrofit a turbine next year, and it is necessary to replace the turbine rotor with a new one. Among the technical requirements for the new rotor, the following provision is specified: \"All rotor blades must be full three-dimensional blades with excellent energy-saving performance.\" Question: What exactly are the fully three-dimensional turbine blades? What is the difference between fully three-dimensional blades and two-dimensional blades?
The rotor is a core component of a steam turbine, and the machining requirements for its blades are also quite high. The simplest option is to purchase directly from the original manufacturer, although the price may be a bit higher. If looking for alternative methods of repair, the following requirements must be met at a minimum: 1. The material and dimensions of the rotor must comply with the specifications in the original drawings ； 2. When replacing the blades, it is generally recommended to replace all the blades on the first-stage impeller at once. Moreover, the processing time for new blades is usually quite long, so it is necessary to allow for sufficient lead time ； 3. After repair, a high-speed dynamic balance test must be conducted again ；
The difference between 3D and 2D lies in whether the impeller is flat or three-dimensional
