Common alarms and faults of air compressors
H. Common alarms of air compressors are:
1. Too high temperature: refers to the temperature of the oil and gas mixture at the outlet of the compressor, which is greater than or equal to 110°C to alarm and 120°C to trip.
2. The pressure is too high: it refers to the compressor outlet pressure, if it is higher than 10bar, it will alarm and trip at 15bar.
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 are easy to separate.
(The suspended oil particles with a true diameter of 1um or less) must be filtered through the micron and glass fiber filter layers of the oil and gas separation filter element. The compressor discharges more pure and oil-free pressure
When the solid particles in the compressed air pass through the oil separation core, they are placed in the filter layer, which leads to the continuous increase of the pressure differential resistance of the oil separation core. With oil separation core
As the use time increases, when the pressure difference of the oil separator 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 passing through the filter increases, and negative pressure is generated at the inlet of the compressor.
5. Oil filter: Due to the long-term operation of the air compressor, the impurities in the air are sucked into the compressor, causing the oil filter to be dirty and clogged, and the pressure difference between the front and rear of the oil filter is 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, and the compressed air will be less entrained from the air compressor.
Part of the oil causes the loss of air compressor oil, resulting in high oil temperature.
7. High exhaust temperature: refers to the poor heat dissipation of the air compressor, and the oil quantity and oil quality of the air compressor are abnormal.
8. Low oil level: Refers to the low oil level in the oil-gas separator of the air compressor, and no oil can be seen in the oil level gauge.
9. Line pressure: The load/no-load control of the air compressor exceeds the operating pressure of the machine.

(Common faults of port and air compressor
1. Power failure: The power supply/control power supply of the air compressor is out of power. Treatment method: Check whether the power supply and control power supply have electricity.
2. Motor temperature: the motor starts too frequently, the load is too heavy, the motor cooling is not sufficient, the motor itself or the bearing has problems, the sensor, etc.
Treatment method: limit the number of motor starts and reduce the loading set pressure.
3. Compressor temperature: The temperature of the oil-air mixture at the compressor outlet reaches 120°C.
Treatment method: keep the air compressor well ventilated, check that the radiator is not covered by debris, the radiator has good heat dissipation, check the air compressor oil level, cooling fan, temperature sensor
device.
4. Low startup temperature: The air compressor panel shows that the temperature is lower than 1°C.
5. The pressure is too high: the compressor outlet pressure reaches 15bar and trips.
Treatment method: Check whether the loading set pressure is too high, the pressure sensor, etc., and contact the maintenance to check the pressure regulating valve and the unloading valve.
6. Pressure sensor: There is a problem with the pressure, temperature and sensor wiring of each pipeline of the air compressor.
Treatment method: contact maintenance or the manufacturer.
7. Motor steering error: the motor wiring is wrong or the star/delta cannot be switched normally when the motor starts, and the turn signal sensor on the compressor body is faulty, causing the air compressor
Reports the wrong direction of the motor.
Solution: Contact maintenance to check whether the phase sequence wiring of the motor is correct.
8. Expiration of maintenance period: The maintenance period of the air compressor has expired and has exceeded 100 hours.
Treatment method: Contact maintenance to maintain the air compressor. After the maintenance is completed, the operator will reset the maintenance time.
9. Solenoid valve failure: the solenoid valve is loose or the lead connector is loose or disconnected.
Treatment method: contact maintenance.
10. Cooling system failure: the cooling fan of the air compressor does not rotate or one of the cooling fans does not rotate, the fan is deformed, the fan relay is aging and the wiring is loose.
Treatment method: Contact maintenance to check whether the motor and motor wiring are in good condition.
