Screw air compressor maintenance how to turn off the alarm reminder
Faults will inevitably occur during the use of the screw air compressor, and an alarm will be triggered once a fault occurs. You can learn more about it!
- 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.
- The alarm is triggered when the pressure exceeds the preset value: it refers to the outlet pressure of the compressor. If it is higher than 10bar, it will alarm and trip at 15bar.
- The heat dissipation of the screw air compressor is poor, and the oil is inferior.
- The oil temperature of the air compressor is high: due to the 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 entrain a small amount of oil from the air compressor, causing the loss of air compressor oil , resulting in high oil temperature.
- High temperature alarm: refers to the temperature of the oil-air mixture at the outlet of the compressor, if it is greater than or equal to 110°C, it will alarm or trip at 120°C.
Alarm caused by air filter: When the air filter is dirty or blocked, the resistance of air passing through the filter increases, and negative pressure is generated at the compressor inlet. Oil filter: Due to the operation of the air compressor, the impurities in the air are sucked into the compressor and cause the oil filter to become dirty and clogged, which makes the pressure difference between the front and back of the oil filter too large. The oil-gas separator of the screw air compressor has a fault alarm: the compressed air coming out of the compressor head entrains large and small oil droplets. Large oil droplets are easy to separate when passing through the oil-gas separation tank, while small oil droplets need to be filtered through the micron and glass fiber filter material layer of the oil-gas separation filter element. So that the compressor discharges more pure and oil-free compressed air. The solid particles in the compressed air stay in the filter layer when passing through the oil separator core, which leads to an increase in the pressure difference resistance of the oil separator core. As the use time of the oil separator core increases, the filter element needs to be replaced when the pressure difference of the oil separator core reaches 0.08 to 0.1Mpa.
