Analysis of blower vibration

　　 1. There is a lot of dirt in the impeller

If the impeller of the Roots blower is damaged due to the damage of the filter system, the Roots blower absorbs a large amount of dirt. Such dirt and impurities will stay on the impeller, resulting in the impeller gap being too small. At this time, there may be friction between the impeller and the impeller. This kind of mutual friction can cause abnormal vibration of the Roots blower.

　　Note: Roots blowers have different sizes and different vibration standards

　　2. the anchor bolts are loose

　　 The loosening of the anchor bolts will cause abnormal vibration of the Roots blower. This is the most common cause of vibration. When we find that the anchor bolts of the Roots blower are not tightly fixed, we must reinforce them in time to avoid damage to the Roots blower.

3. Gear wear

　　 Gear wear will cause uneven gear engagement and abnormal rotation of the fan. For a long time, it will cause the transmission shaft to be unbalanced, and then the impeller will be unbalanced, and the deviation of the impeller gap will cause abnormal vibration of the Roots blower.

　　4, the factory static and dynamic balance test failed

　　 This type of Roots blower is an unqualified product. The static balance and dynamic balance have a large deviation, which can easily cause abnormal vibration of the fan.

　　 5. Abnormal motor vibration

　　 The motor has abnormal vibration, which is transmitted to the Roots blower through the bearing, and the Roots blower resonates, causing the overall vibration amplitude to be too large.

　　Summary: During the operation of the Roots blower, we need to do a timely inspection to avoid the existence of abnormal conditions. Once an abnormality is found in the Roots blower, please stop the machine for maintenance in time.
