Common faults of air conditioner bearing!

Bearing is a pivotal component in contemporary mechanical equipment. Its main function is to support the mechanical rotating body, reduce its friction coefficient in the movement process, and ensure its rotation accuracy. Therefore, its application range is very wide and the market demand is strong.

High-quality air conditioner bearing can be used for a long time when used correctly. Of course, improper use and operation will also lead to a series of failures. In central air-conditioning, the most common ones are compressor bearing burn and compressor bearing peeling.

01 compressor bearing burn
Fault phenomenon: the air conditioner bearing becomes hot and discolored, and then burns and cannot rotate.

Cause of failure:
1, the clearance is too small (including the deformation part clearance is too small);
2. Insufficient lubrication or improper lubricant;
3. Excessive load (excessive preloading);
4. Roller deflection;

Workaround:
1. Set appropriate clearance (increase air conditioner bearing);
2. Check the lubricant type to ensure the injection amount;
3. Check the conditions of use;
4. Prevent positioning error;
5. Check the design around the bearing (including bearing heating);
6. Improve the air conditioner bearing assembly method;

02 compressor bearing peeling

Fault phenomenon: the running surface is obviously convex and concave after peeling.

Cause of failure:
1. Excessive load and improper use;
2. Poor installation;
3. Poor accuracy of shaft or air conditioner bearing box;
4. The air conditioner bearing clearance is too small;
5. Invasion of foreign bodies;
6. Rusting occurs;
7. The hardness decreases due to abnormal high temperature;

Workaround:
1. Re-study the conditions of use;
2. Re-select the air conditioner bearing;
3. Reconsider the clearance;
4. Check the machining accuracy of shaft and bearing box;
5. Study the design around the air conditioner bearing;
6. Check the installation method;
7, check the lubricant and lubrication method;

It is an indispensable and important part of compressor equipment, petrochemical equipment, air conditioning and industrial refrigeration. These industries require bearings with low heat generation, long service life, resistance to various working conditions, low noise and low vibration.
