罗茨风机存有振动是正常情况，罗茨风机的异常振动可能是由一些原因造成的，如果长期存在异常振动，对于罗茨风机的损耗将会增大，罗茨风机的使用寿命也将会受到影响。来源网址:Www.hdfJ11.COm

It is normal for a Roots blower to experience vibration. Abnormal vibration of a Roots blower may be caused by some reasons. If abnormal vibration persists for a long time, the wear and tear of the Roots blower will increase, and the service life of the Roots blower will also be affected. Source URL: Www.hdfJ11.COm

　　罗茨风机的损坏往往是长期不良运行造成的，有些罗茨风机可以使用5到10年，而有些罗茨风机在不良运转的情况下可能使用2到3年就坏了。此时又将重新花钱采购新设备，今天小编为您解读一下罗茨风机不良运行：异常振动！

The damage of Roots blowers is often caused by long-term poor operation. Some Roots blowers can be used for 5 to 10 years, while others may break down after 2 to 3 years of poor operation. At this point, we will spend money again to purchase new equipment. Today, the editor will explain to you the poor operation of the Roots blower: abnormal vibration!

　　造成罗茨风机异常振动的原因有以下几条：

The reasons for abnormal vibration of Roots blower are as follows:

　　1、叶轮存有大量污垢

1. The impeller contains a large amount of dirt

　　罗茨风机的叶轮，如果因为过滤系统损坏，造成罗茨风机吸收大量的污垢，该类污垢杂质滞留在叶轮上，导致叶轮间隙过小，此时叶轮与叶轮之间可能会出现相互摩擦，而这种相互摩擦会引起罗茨风机异常振动。

If the impeller of a Roots blower is damaged due to the filtration system, causing the Roots blower to absorb a large amount of dirt, such dirt and impurities will accumulate on the impeller, resulting in a small clearance between the impellers. At this time, there may be friction between the impellers, which can cause abnormal vibration of the Roots blower.

　　2、地脚螺栓松动

2. Loose foundation bolts

　　地脚螺栓的松动，会造成罗茨风机异常振动，这是最常见的振动原因，我们在发现罗茨风机地脚螺栓固定不紧时，要及时进行加固，避免造成罗茨风机的损坏。

The loosening of the anchor bolts can cause abnormal vibration of the Roots blower, which is the most common cause of vibration. When we find that the anchor bolts of the Roots blower are not tightly fixed, we should promptly reinforce them to avoid damage to the Roots blower.

　　3、齿轮磨损

3. Gear wear

　　齿轮磨损会造成齿轮咬合不均，造成风机的转动异常，长期以往，会造成传动轴出现失衡，进而造成叶轮的失衡，出现叶轮间隙的偏差造成罗茨风机异常振动。

Gear wear can cause uneven meshing of gears, resulting in abnormal rotation of the fan. Over time, it can cause the transmission shaft to become unbalanced, which in turn leads to the imbalance of the impeller and the deviation of the impeller clearance, causing abnormal vibration of the Roots blower.

　　4、出厂静动平衡测试不合格

4. Factory static and dynamic balance test failed

　　该类罗茨风机属于不合格产品，静平衡动平衡偏差较大，极易造成风机的异常振动等情况。

This type of Roots blower belongs to unqualified products, with large deviations in static and dynamic balance, which can easily cause abnormal vibration of the blower.

　　5、电机异常振动

5. Abnormal vibration of motor

　　电机存在有异常振动，通过轴承传递与罗茨风机，罗茨风机在共振的情况下导致整体振动幅度过大。

There is abnormal vibration in the motor, which is transmitted to the Roots blower through bearings. The Roots blower experiences excessive overall vibration amplitude due to resonance.
