The most used place for rotor repair is the air compressor, and the air compressor rotor repair is the most important part of the air compressor maintenance. Regular maintenance of the air compressor rotor and bearings can better extend the use of this machine. years. So what are the causes of bearing damage in the repair of air compressor rotors? Let's discuss with me below!

When the oil-injected screw compressor is used for too long, the screw rotor may have the following problems:

1. Bearing wear; 2. The meshing gap is too large; 3. The oil circuit is not smooth; 4. The vibration and running noise are too large.

The reason for the above problems is that mechanical wear and fatigue will inevitably occur when the rotor runs under high load and high temperature for a long time. If we do not check and repair in time, we may face a lot of losses.

After the air compressor rotor is worn, the following problems may occur:

1. Abnormal friction and movement of the rotor; 2. Reduced operational reliability; 3. Reduced efficiency and increased energy consumption; 4. Sudden damage, completely affecting production.

And the repair of the air compressor rotor is not for all machines. The damage of some machines is also on the bearing. Not all damaged bearings can be repaired. However, for each damaged bearing, it is necessary to consider the repair or replacement of new bearings. The cause and extent of damage is assessed to prevent or reduce further damage.

There are many reasons for bearing damage, such as improper installation, dirt intrusion or moisture intrusion, etc. are common causes of early damage to many bearings. The following is an analysis of some common damage causes of large-scale bearings and corresponding preventive measures that can extend bearing life:

① Improper operation: improper installation, operation or disassembly may cause the cage to be deformed or damaged. Precautions: Use suitable handling, equipment and disassembly tools.

② Insufficient smoothing: Insufficient or improper smoothing may result in abrasion of components or severe bearing deformation. Preventive measures: Improve the lubricating system, and supplement or replace the lubricating agent regularly and properly.

③ Rust and Corrosion: Touching water may cause the bearing elements to corrode and rust. Bearings damaged by rust may fall off during operation. Preventive measures: We should check the seal regularly to ensure good sealing effect and store the bearing correctly.

④ Current: Energizing while the bearing is rolling may cause grooves or nicks. Improper grounding of electrical operations can cause minor burns when the bearing is stopped. Precautions: Reduce or prevent current flow through bearings by properly connecting parts other than bearings before welding.

⑤ External materials: Abrasive particle contamination and intrusion of debris may cause wear, galling and sagging of bearing surfaces. Precautions: Remove invasive particles and debris, replace lubricant, check sealing system.

⑥ Eccentricity: Eccentricity, skew or excessive load may cause geometric stress to concentrate or surface to fall off. Precautions: Accurate machining of housings and shoulders.

There are many reasons for bearing damage in air compressors. The above are just some of the reasons for bearing damage in the repair of large-scale air compressor rotors. To avoid bearing damage, the staff must not only maintain regular maintenance, but also carry out corresponding maintenance and maintenance. Check.
