風機葉輪使用中會出現震動現象，這是什么原因呢？
    Vibration phenomenon occurs in the use of fan impeller. What is the reason?
    風機葉輪使用中會出現震動是葉輪不平衡的原因，葉輪出現不平衡的原因是什么呢？出現問題該如何解決呢？
    The vibration of fan impeller is caused by the imbalance of impeller. What is the reason for the imbalance of impeller? How to solve the problem?
    1、葉輪表面在高溫下很容易氧化,生成厚厚的氧化皮.這些氧化皮與葉輪表面的結合力并不是均勻的,某些氧化皮受振動或離心力的作用會自動脫落,這也是造成葉輪不平衡的一個原因。
    the surface of the impeller is easy to oxidize at high temperature to produce a thick oxide skin. The bonding force between these oxide skins and the surface of the impeller is not uniform, and some oxide skin will fall off automatically by the action of vibration or centrifugal force, which is also a reason for the imbalance of the impeller.

    2、風機的葉輪的磨損問題,這是產生葉輪使用不平衡的直接原因,磨損的狀況是因干式除塵裝置引起,它雖然可以除掉煙氣中絕大部分大顆粒粉塵,但少量大顆粒和許多微小的粉塵顆粒隨同高溫、高速的煙氣一起通過引風機,使葉片遭受連續不斷地沖刷.這樣,在葉片出口處形成刀刃狀磨損.由于這種磨損是不規則的,因此造成了葉輪的不平衡。
    The abrasion of the impeller of the fan is the most direct reason for the uneven use of the impeller. The condition of the wear is caused by the dry dust removal device. Although it can remove most of the large particle dust in the flue gas, a small amount of large particles and a lot of small dust particles are used together with the high temperature and high speed flue gas through the fan to make the leaves. The blade is subjected to continuous erosion. In this way, blade wear is formed at the outlet of the blade. Due to the irregular wear, the impeller is unbalanced.
    3、風機結垢問題是濕法除塵裝置凈化煙氣濕度很大,未除凈的粉塵顆粒雖然很小,但粘度很大.當它們通過引風機時,在氣體渦流的作用下會被吸附在葉片非工作面上,特別在非工作面的進口處與出口處形成比較嚴重的粉塵結垢,并且逐漸增厚.造成了葉輪結垢。
    The problem of wind turbine scaling is that the wet dust removal device purify the humidity of the flue gas very much. Although the dust particles are very small, the viscosity of the dust particles is very small. When they pass the air draught machine, they will be adsorbed on the non working surface of the blade under the action of the gas eddy, especially in the inlet and outlet of the non working surface. Gradually thickening, causing the impellers to scale.
    風機震動后，葉輪就需要重新做動靜平衡測試和校正，否則會嚴重影響風機的穩定性，同時也會縮短使用壽命。
    After the fan vibrates, the impeller needs to be re tested and corrected dynamically, otherwise it will seriously affect the stability of the fan and shorten the service life.
    以上說到的只是常出現的幾個問題，使用過程中還會遇到一些其它原因,處理的時候要根據風機的實際情況,然后進行解決問題。
    The above mentioned is only a few problems that often occur, and some other reasons are encountered in the process of use. When dealing with the actual situation of the fan, the problem will be solved.
