In modern industrial operations, screw air compressors have long evolved from auxiliary equipment into a core power source that directly supports production continuity and operational safety. Whether in manufacturing, energy, or process industries, the stability of compressed air supply plays a decisive role in maintaining smooth workflows. As such, any malfunction of a screw air compressor is never an isolated equipment issue—it can interrupt production schedules, increase maintenance costs, and in certain scenarios, pose safety risks to personnel and facilities.
Based on extensive field experience and long-term operational feedback, common faults in screw air compressors typically manifest as starting difficulties, unexpected automatic shutdowns, abnormal vibrations, and temperature irregularities. These issues are often linked to factors such as improper slide valve positioning, normal wear of critical components, unstable or insufficient power supply, pipeline resonance, or inadequate lubrication and cooling conditions. While these problems may appear complex, they are usually predictable, diagnosable, and manageable when addressed early and correctly.
Effective solutions focus not only on fault elimination, but on restoring long-term reliability. This includes precise adjustment of the slide valve to ensure optimal load control, timely repair or replacement of worn components, optimization of the control and protection logic, and strict management of lubrication and cooling systems. More importantly, a systematic approach to fault analysis and preventive maintenance can significantly reduce unplanned downtime, extend equipment service life, and protect our customers’ production investments.
From our perspective, reliable compressed air is more than a technical requirement—it is a commitment to stable production, predictable costs, and operational peace of mind. By proactively understanding common fault patterns and implementing targeted solutions, we work alongside our customers to ensure that their air systems operate efficiently, safely, and consistently, even under demanding industrial conditions.
Common Fault Types, Causes, and Solutions for screw air compressor:
In the daily operation of screw air compressors, certain faults tend to occur more frequently due to long operating hours and complex working conditions. Common fault types include difficulty in starting, unexpected automatic shutdowns, abnormal vibration or noise, excessive discharge temperature, and unstable pressure output. These issues can directly affect production efficiency and, if not addressed in time, may lead to further equipment damage.
Routine Inspection and Operating Checks
Daily inspection of key operating parameters such as pressure, temperature, oil level, and running sound helps ensure the compressor is operating within normal ranges. Any abnormal readings or noises should be addressed promptly to avoid unplanned shutdowns. Consistent checks form the foundation of stable and reliable operation.
Lubrication, Cooling, and Filtration Management
Proper lubrication and efficient cooling are critical to protecting internal components and controlling operating temperature. Oil condition, cooling performance, and filter cleanliness should be checked regularly to ensure effective heat dissipation and smooth airflow. Well-maintained lubrication and filtration systems significantly extend equipment service life.
Cleaning, Tightening, and System Integrity
Keeping the compressor and surrounding area clean helps prevent dust accumulation and heat buildup. Regularly tightening bolts, fittings, and electrical connections reduces vibration and the risk of leakage or failure. Maintaining overall system integrity supports long-term reliability and safe operation.
