What are the deformation and damage conditions of Roots blower impeller?

What are the deformation and damage conditions of Roots blower impeller? The equipment in Roots blower industry is a kind of frequently operated mechanical equipment. It is inevitable that some problems will occur during the operation, such as the damage or deformation of our common impeller. What are the main reasons for these? Let's answer them one by one:

Generally, there are two cases of deformation and damage of the impeller during the operation of the fan: one is the normal wear of the fan that has been running for a long time and exceeds its service life; The other is the sudden damage caused by not reaching the design life. We won't say much about the former, but only need to replace the impeller.

The reasons for the latter situation are:

1. The blade surface or rivet head is corroded or worn.

2. Decision and blade looseness. 3. The production of the impeller is unbalanced, and the vibration value exceeds the specified standard, which makes the impeller incline or deform.

Jinan Hengli Blower describes the solution:

1. If some blades or rivets are damaged, the damaged blades or rivets can be replaced. If most blades or rivets are damaged, the impeller should be replaced.

2. If some rivets are loose, they can be fastened with a small punch. If they are not effective, new rivets with the same material as the original rivets can be replaced.

3. If the deflection of the impeller is too large after deformation, the impeller can be removed and corrected with a hammer, or the impeller can be placed flat on the platform at the edge of one side of the gland plate until the impeller is corrected. Note that the impeller needs to be balanced after the impeller is corrected.

Jinan Hengli Blower, as a common fan equipment, will basically be in a long-term operation state and will be more or less worn, so we need to carry out regular maintenance and inspection of the fan. The following are the standards for regular inspection and maintenance of the fan:

1. The fan runs continuously for 3 to 6 months, and the grease should be replaced once to fill 2/3 of the bearing space.

2. The fan runs continuously for 3 to 6 months, and the rolling bearing shall be checked once to check the contact between rolling and raceway surface and the tightness of the inner ring fit.

3. Jinan Hengli Blower shall be regularly overhauled to remove dust and dirt inside the fan, and keep the fan clean, which is conducive to the normal operation of the fan and the stability of air pressure and volume.
