For a description of the loss of the whole fan-based mathematical model to analyze the loss of more than runner may appear in Shanxi two-stage axial fans with a simple formula to express the relationship between the flow field and lost, then the loss of superposition, this conduct computing performance. This method is too dependent on relevant experience factor, and wide ranges of these coefficients can not be reasonably selected according to the specific form of the flow channel, while ignoring the mutual influence and interaction between the loss and therefore the actual situation quite different. Fan is a key power plant auxiliary Huairen temperature axial fans, axial fans due to the high efficiency and low energy consumption and are widely used. In actual operation. Many power plants due to axial fans especially variable pitch axial fan axial fan prices Shuozhou poor reliability, frequently malfunction, leading to unplanned plant shutdown or load shedding. Affecting the power generation unit. Therefore, to solve these problems from the root. Large thermal power plants to improve the reliability of axial fan is running very necessary and urgent. This paper describes the factors that affect the reliability of the power plant turbine. Proposed to improve the reliability of the axial fan design and operation countermeasures.
