What are the reasons for the vibration of Roots blower?

What are the reasons for the vibration of Roots blower? There may be several reasons for the vibration of Roots blower during operation, which are described in detail below!

1. Fan impeller imbalance: impeller imbalance is one of the main causes of Roots blower vibration. In the process of use, the weight distribution of the impeller is uneven or will lead to the vibration of the impeller when rotating at high speed.

　　2. Poor contact of fan spring seat: Roots fan spring seat is an important part of reducing machine vibration and bears the force generated by impeller vibration during vibration. If the spring seat has poor contact or the base is not firmly installed, the machine will vibrate.

3. Unstable machine installation: Roots blower must be horizontal and stable during installation. If the installation angle is incorrect or the support bolt is loose, vibration will be caused.

　　4. Bearing wear of Roots blower: the bearing of Roots blower may be excessively worn due to long-term use, including insufficient lubricating oil, high temperature caused by long-term high-speed operation, which will affect the normal operation of the bearing and cause vibration.

5. Excessive friction between the impeller and the flow passage of Roots blower: during the operation of the blower, excessive friction between the impeller and the flow passage may also cause the blower to vibrate.
