羅茨鼓風機做為一種容積式離心風機，自推出至今到更加普遍的應用。羅茨風機以其與眾不同的優點，遭受各行各業的青睞。僅僅機器設備時長越久，在所難免發生一些毛病，變動異響是羅茨鼓風機普遍的問題之一，產生異響和抖動的主要原因是哪些，該怎樣解決，羅茨風機異響和震動產生的原因多而雜，解決辦法也各有不同。

　　下面將逐一詳細介紹造成羅茨風機變動異響的緣故及解決辦法，如文章內容對您有效敬請期待和個人收藏。

　　1、工作壓力不穩定，羅茨鼓風機的噪音值伴隨著工作壓力上升而增加，當變壓發生很大起伏時，噪音也會隨著起伏，發生異響。這時，必須查驗管道及負荷，清除阻塞，時工作壓力平穩在標準值，合理降低異響。

　　2、離心風機嚴重超載，造成負載超溫，乃至導致軸形變，葉輪與外殼磨擦生產制造異響。解決辦法是查驗過濾裝置、出入口背壓式，系統壓力，調節工作狀況，清除負載超溫，必要時再次調節葉輪空隙，增加外殼進氣口側的空隙。

　　3、離心風機生產制造不符生產流程和規范，使用時間很長后外殼變型，導致葉輪與外殼磨擦,或是葉輪與葉輪磨擦，假如葉輪制做不光滑會使磨擦加重，異響增加。必須返廠維修，鏜外殼，換葉輪。

　　4、當羅茨鼓風機的閥門打開時，閥門處會造成銳利的放氣噪音，當閥門不斷開閉則產生異響。解決辦法便是查詢是不是過壓或調節閥門。

　　5、傳動齒輪應用難題，齒輪磨損或是傳動齒輪固定不動不穩固，都可能使傳動齒輪自身傳出異響，并毀壞葉輪的間距及葉輪旋轉的趨同性，造成葉輪互相撞擊造成異響。解決辦法便是拆換傳動齒輪并做好齒輪的潤化。

　　6、滾動軸承應用難題，滾動軸承不符產品質量標準或是滾動軸承損壞，側隙擴大超出標準值，滾動軸承支撐的二根軸會造成震動，產生異響。當振動傳輸到葉輪，還可能毀壞葉輪空隙，使葉輪互相撞擊，導致更高的變動異響。解決辦法是拆換滾動軸承，并做好滾動軸承的潤滑油。

　　7、傳動系統三角帶太緊或太松，風機轉速不穩定，忽快忽慢，傳動齒輪會傳出嘯叫聲。解決辦法是調節三角帶支撐力到適合。

　　8、密封性難題，羅茨鼓風機是強制性縮小供氣的工業設備，因密封性不合理發生氣體晃動，碰撞離心風機內腔造成異響，要更改和改進密封性。

　　9、出入口阻塞，羅茨風機進出口貿易不通暢，沒法排風系統，造成工作壓力持續升高，相反危害電流量升高，也會造成設備異響，因而消除臟東西和臟物，維持出入口清理。

　　10、離心風機基座螺栓松動或是構件相互連接不牢固，也可能造成離心風機傳出噪音。解決辦法便是牢固好地腳螺栓，使之擰緊。

　　11、有臟東西卡在葉輪空隙中，使葉輪不平衡，導致震動和異響。解決辦法便是消除臟東西。

　　羅茨風機在平時應用時要做好日常維護，要定期維護空氣過濾器、軸承潤滑油及機油箱剩余油等是否正常，設備運行時做好各類數據記錄，若有異響變動請關機解決。只要對機器設備長期的呵護和養護恰當，將維持機器設備優良運行，并極大增加羅茨風機的使用期限。

　　Roots blower, as a positive displacement centrifugal fan, has been widely used since its introduction. Roots blower is favored by all walks of life for its unique advantages. As long as the machine and equipment are used, it is inevitable that some problems will occur. Abnormal noise caused by change is one of the common problems of Roots blower. What are the main causes of abnormal noise and vibration and how to solve them? The causes of abnormal noise and vibration of Roots blower are various, and the solutions are different.

　　The reasons for the abnormal noise caused by the change of Roots blower and the solutions will be introduced in detail one by one. If the content of this article is effective for you, please look forward to it and collect it personally.

　　1. The working pressure is unstable. The noise value of Roots blower increases with the increase of working pressure. When the variable pressure fluctuates greatly, the noise will also fluctuate and make abnormal noise. At this time, the pipeline and load must be checked, the blockage must be removed, the working pressure should be stable at the standard value, and the abnormal noise should be reasonably reduced.

　　2. The centrifugal fan is seriously overloaded, resulting in over temperature of the load, even shaft deformation, and abnormal noise caused by friction between the impeller and the shell. The solution is to check the filter device, inlet and outlet back pressure type, system pressure, adjust the working condition, remove the load overtemperature, adjust the impeller clearance again if necessary, and increase the clearance at the air inlet side of the shell.

　　3. The manufacturing of centrifugal fan does not conform to the production process and specifications, and the shell is deformed after a long time of use, resulting in the friction between the impeller and the shell, or the friction between the impeller and the impeller. If the impeller is not smooth, the friction will increase and the abnormal noise will increase. Must return to the factory for maintenance, boring the shell and replacing the impeller.

　　4. When the valve of Roots blower is opened, sharp bleeding noise will be caused at the valve, and abnormal noise will be generated when the valve is continuously opened and closed. The solution is to check whether there is overpressure or regulating valve.

　　5. The application of transmission gear is difficult. Gear wear or the transmission gear is fixed and unstable, which may make the transmission gear send out abnormal noise, destroy the spacing of impellers and the convergence of impeller rotation, and cause the impellers to collide with each other to cause abnormal noise. The solution is to replace the transmission gear and moisten the gear.

　　6. The application of rolling bearings is difficult. The rolling bearings do not meet the product quality standards, or the rolling bearings are damaged, and the side clearance is expanded beyond the standard value. The two shafts supported by the rolling bearings will cause vibration and produce abnormal noise. When the vibration is transmitted to the impeller, it may also destroy the impeller gap, so that the impellers collide with each other, resulting in higher abnormal noise. The solution is to remove and replace the rolling bearing and make the lubricating oil of the rolling bearing.

　　7. The triangle belt of the transmission system is too tight or loose, the fan speed is unstable, fast and slow, and the transmission gear will emit a howling sound. The solution is to adjust the support force of the triangle belt to fit.

　　8. Sealing problem: Roots blower is an industrial equipment that forcibly reduces the gas supply. Due to unreasonable sealing, the gas shakes and collides with the inner cavity of the centrifugal fan, resulting in abnormal noise. The sealing shall be changed and improved.

　　9. The inlet and outlet are blocked, the import and export trade of Roots blower is not smooth, and there is no way to exhaust the air system, resulting in the continuous increase of working pressure. On the contrary, the increase of harmful current will also cause abnormal noise of the equipment, thus eliminating dirt and dirt and maintaining the cleaning of the inlet and outlet.

　　10. Loose bolts on the foundation of the centrifugal fan or weak connection of components may also cause noise from the centrifugal fan. The solution is to tighten the foundation bolts firmly.

　　11. There is dirt stuck in the gap of the impeller, which makes the impeller unbalanced, resulting in vibration and abnormal noise. The solution is to get rid of dirt.

　　The roots blower shall be subject to routine maintenance during normal application. It is required to regularly maintain whether the air filter, bearing lubricating oil and residual oil in the oil tank are normal. Various data records shall be made during equipment operation. In case of abnormal noise changes, please shut down the machine for solution. As long as the long-term care and maintenance of machinery and equipment are appropriate, the excellent operation of machinery and equipment will be maintained and the service life of Roots blower will be greatly increased.
