Causes and solutions of the impeller rubbing against the casing of the three blade roots blower

How to adjust the impeller of three leaf roots blower against the casing? There are many reasons why the impeller of the three leaf roots blower rubs against the casing. Now let's look at the causes and solutions of the three leaf roots blower rubs against the casing! The cause of the three leaf roots blower rubbing against the casing.

1. Impeller material problem

The impeller of the three blade roots blower is made of poor material. During the use, wear, corrosion or slag fall occurred, which caused the gap between the impeller and the casing to change and the impeller to rub against the casing.

2. Impeller machining accuracy is not enough

If the impeller of three blade Roots blower is not processed with high precision and dynamic balance test is not conducted during processing, the fan with large precision error may rub against the casing in later use.

3. The fan has over reverse fault

If the fan has the fault of over reversal and reverse rotation, the impeller may have some problems, which may cause the clearance to change and the phenomenon of rubbing against the casing. How to deal with the fault of Roots blower in power plant quickly?

4. The bearing is damaged

Bearing is a very important part. If our bearing is worn, it may also cause friction between Roots blower impeller and casing.

5. Gear damage

No matter the driving gear or driven gear, as long as there is a gear fault, it may affect the deviation of the impeller, causing friction between the casing and the impeller.

6. Casing deformation

The casing deformation is also the reason for the friction between the impeller and the casing. You may ask, how can the casing deform? In fact, in many cases, it may lead to casing deformation, such as too high casing temperature, poor casing material, insufficient casing thickness, and casing deformation caused by external force collision, which may cause mutual friction between the two.

In view of the above reasons, how should we deal with the friction between the impeller and the casing of the three blade Roots blower? For this phenomenon, Sanniu fan gives the following solutions:

1. With regard to the material problem, if the Roots blower we are using causes friction in the impeller casing due to the material, we recommend replacing the fan head. If you do not want to replace it, you can choose to repair it. However, the price of repair and replacement is not much different.

2. If the friction of our three blade Roots blower is caused by other damages, we need to replace the accessories of the blower. After replacement, check whether the clearance of each accessory is within the error. If the impeller or casing is severely worn, repair both before installation.

3. If our Roots blower has had a fan fault before, we need to check the parts that have failed before, and then check the relevant parts for troubleshooting.

4. For the repair of three leaf roots blower, it is generally necessary to return to the roots blower manufacturer. For the friction fault of roots blower, it is necessary to find the fault reason of the blower, and then carry out maintenance, inspection, delivery and other steps.
