As the general equipment of major manufacturers today, air compressors will inevitably encounter faults during use. Although the faults vary in size, they will cause losses to our manufacturing. Air compressors are the general equipment of major manufacturers today. , It is inevitable that you will encounter faults during the use process. Although the faults vary in size, they will cause losses to our production. Some air compressors have an alarm mechanism, and some problems we cannot detect, so we are familiar with air pressure It is quite necessary for the malfunction of the machine to be dealt with in a timely manner. Now the machine will summarize the causes and treatment methods of various alarms for the convenience of everyone.
Common alarms of air compressors
1. Excessive temperature: Refers to the temperature of the oil and gas mixture at the outlet of the air compressor, which is greater than or equal to 110°C and alarms and 120°C trips.
2. Pressure is too high: Refers to the outlet pressure of the air compressor, which is higher than 10bar and alarms and 15bar trips.
3. Oil and gas separator: the compressed air from the air compressor head entrains large and small oil droplets. Large oil droplets are easy to separate when passing through the oil and gas separation tank, while small oil droplets (suspended oil particles below 1um in diameter) must be filtered through the micron and glass fiber filter layer of the oil and gas separation filter. So that the air compressor discharges more pure and oil-free compressed air. The solid particles in the compressed air pass through the oil core and stay in the filter layer, which causes the pressure difference (resistance) of the oil core to increase continuously. As the use time of the oil separation core increases, when the pressure difference of the oil separation core reaches 0.08 to 0.1Mpa, the filter element must be replaced.
4. Air filter: When the air filter is dirty or blocked, the resistance of the air through the filter increases, and negative pressure is generated at the inlet of the air compressor.
5. Oil filter: Due to the long-term operation of the air compressor, the impurities in the air are sucked into the air compressor and cause the oil filter to be dirty and clogged, causing the pressure difference before and after the oil filter to be too large.
6. High oil temperature: Due to the long-term operation of the air compressor, the oil quality is aging, the oil return path is not smooth, the oil filter is blocked (dǔ sè), and the compressed air from the air compressor will entrain a small amount of oil and cause air compressor oil The loss of oil, resulting in high oil temperature.
7. High exhaust temperature: It means that the air compressor has poor heat dissipation, and the air compressor oil volume and oil quality are abnormal. Ingersoll Rand's high-efficiency motor for second-hand air compressors: Class F insulation, Class B temperature rise, protection level up to IP55, effectively preventing dust and moisture from entering the motor, extending the service life of the motor.
8. Low oil level: Refers to the low oil level in the oil and gas separator of the air compressor, and no oil can be seen in the oil level gauge.
9. Pipeline pressure: The load/no-load control of the air compressor exceeds the operating pressure of the machine. The material of the used oil-free air compressor rental machine does not contain oily substances, which avoids the pollution of the terminal equipment by the oil-free air compressor. Therefore, it is necessary to choose a laboratory silent oil-free air compressor to ensure air quality.
As for the common failures of air compressors and quick solutions, here is a simple table for air compressors. You can refer to the check-in table below. Air compressors are used by different people and in different environments, so the failure may not be the points mentioned above. In addition to contacting the after-sales service, normal use in accordance with the specifications is also an effective way to avoid failure.
