2. Faulty Exhaust Valve: Malfunctioning exhaust valves can hinder compressor operation, generating excessive heat and pressure and leading to current overload shutdowns.
3. Exceeding Rated Pressure: Excessive pressure can increase motor load, leading to overheating and shutdown of the machine.
4. Faulty Drive Motor: Motor winding faults or leaks can easily cause motor overload, resulting in significant fluctuations in current and compressor shutdown.
5. Contactor Malfunction: Contactors with aging contacts or poor contact may cause increased current, resulting in overload shutdowns.
6. Pressure Gauge Error: Large errors in pressure gauge readings may result in the setting of current levels that are either too high or too low, causing equipment overload shutdowns.
7. Loose Wiring: Timely addressing of any loose wiring can prevent potential issues.
8. Oil Separator Blockage: Blockages can increase internal pressure, resulting in increased load and current, leading to overload shutdowns.
9. Filter Blockage: Blockages in air filters and oil-gas separators can impede normal airflow, causing the machine to operate inefficiently or even shut down.
10.Circuit Malfunction: The electrical control system of screw air compressors includes numerous circuits. Any circuit faults can result in abnormal operation or overload shutdowns.
11. Overload Protection Device Malfunction: Faulty operation of overload protection devices may cause frequent shutdowns of the compressor.
12. Fan Rotor Blockage or Fan Motor Fault: These issues can lead to excessive fan loads, triggering overload protection devices and causing shutdowns.
13. Lubricating Oil Issues: Insufficient lubricating oil or poor-quality oil can result in inadequate lubrication of the main unit, increasing wear on screws and bearings and leading to machine overload.
14. Electrical Control System Malfunction: When the electrical control system malfunctions, the pressure control system of the air compressor may fail to regulate pressure properly, potentially leading to high-pressure shutdowns.
By addressing these potential causes, operators can prevent or mitigate overload shutdowns, ensuring the smooth and efficient operation of screw air compressors.
