Three commonly used monitoring indicators for refrigeration compressor lubricants

The lubricating oil used in the compressor is very critical, and the detection of lubricating oil and its replacement cycle are also closely related to the process control in the production process. If the cleanliness of the condenser, evaporator, and system pipelines of the compressor system can be controlled well during use, relatively speaking, less pollutants can enter the compressor. And the maintenance period can be relatively extended. Let's take a look at the main monitoring indicators of lubricants in compressors.

　　3 commonly used monitoring indicators for compressor lubricants

　　1, PH value index:

　　 If the lubricating oil in the compressor undergoes acidification, it will directly affect the motor and reduce the service life. Therefore, maintenance personnel are required to regularly check whether the acidity of the lubricating oil is qualified. Under normal circumstances, if the acidity of the lubricating oil reaches below PH6, it can no longer be used, but the lubricating oil must be replaced immediately. If the conditions do not allow to check the acidification of the lubricating oil, the filter drier in the system should be replaced regularly to ensure that the dryness of the system is maintained in a normal state, which is beneficial to maintain the normal PH value of the lubricating oil and prevent acidification.

　　2, pollution index:

The main engine of the compressor with good quality and low price should use special lubricating oil that meets the model, and make sure that there are no impurities in the lubricating oil, because small impurities will also cause wear to the motor during operation, so if you find 100ml lubricating oil If the sundries are more than 5mg, it is recommended to replace the lubricant in time.

　　3, water content:

　　Water will acidify the lubricating oil, so if you find that the moisture in the lubricating oil exceeds 100ppm during use, you need to replace the refrigerating oil. In addition, attention should be paid to the safety of the drum cover when storing the drums of lubricating oil to avoid contamination by the entry of moisture and impurities.

　　 The above three aspects are some important indicators for monitoring Hanbell compressor lubricants. Since the lubricating oil plays a vital role in the operation of the compressor, it is necessary to ensure the quality of the lubricating oil, and to replace and replenish the lubricating oil regularly to ensure the normal operation of the main engine of Hanbell compressor and better air compression. effectiveness.
