This essay explores the potential reasons why an Atlas Copco rotary screw compressor might overheat and shut down during production, providing a comprehensive guide to identifying and addressing these issues.
Basic Operation of a Rotary Screw Compressor
To understand why a rotary screw compressor might overheat, it’s essential to understand its basic operation. A rotary screw compressor works by trapping air between two meshing helical screws (rotors) and compressing it as the screws rotate. The main components involved in this process include:
Air Filter: Cleans the incoming air.
Compressor Element: The rotors that compress the air.
Oil Filter and Separator: Filters and separates the oil used for lubrication and cooling.
Coolers: Reduce the temperature of the compressed air and oil.
Control System: Manages the compressor’s operation.
TROUBLESHOOTING
Common Causes of Overheating
1. Inadequate Ventilation
Proper ventilation is critical for maintaining optimal operating temperatures. Inadequate ventilation can lead to heat build-up within the compressor, causing it to overheat.
Solution: Ensure that the compressor is installed in a well-ventilated area. Check for obstructions around the air intake and exhaust vents. If necessary, install additional fans or ventilation systems to improve airflow.
2. Dirty or Clogged Filters
Air filters, oil filters, and separators play a crucial role in maintaining the compressor's efficiency and temperature. Dirty or clogged filters can restrict airflow and reduce cooling efficiency, leading to overheating.
Solution: Regularly inspect and clean or replace air filters, oil filters, and separators according to the manufacturer’s recommendations. Keeping these components clean ensures proper airflow and cooling.
3. Insufficient Oil Levels
Oil in a rotary screw compressor serves multiple purposes, including lubrication, sealing, and cooling. Low oil levels can impair the cooling process, causing the compressor to overheat.
Solution: Check the oil level regularly and top up as needed. Ensure that you use the correct type and grade of oil specified by Atlas Copco. Implement a regular oil change schedule to maintain optimal oil quality.
4. Faulty Oil Cooler
The oil cooler is responsible for dissipating the heat generated during compression. A faulty or dirty oil cooler can reduce cooling efficiency, leading to overheating.
Solution: Inspect the oil cooler for signs of damage or blockages. Clean the cooler fins to ensure proper heat dissipation. If the cooler is damaged, replace it to restore cooling efficiency.

5. Ambient Temperature
High ambient temperatures can increase the operating temperature of the compressor, making it more susceptible to overheating, especially if the compressor is located in a hot environment or near heat sources.
Solution: Ensure the compressor is installed in a location with a stable, moderate ambient temperature. If high temperatures are unavoidable, consider installing air conditioning or additional cooling systems to reduce the ambient temperature around the compressor.
6. Overloading
Running the compressor at or beyond its maximum capacity can cause it to overheat. Overloading can result from demanding production schedules or using the compressor for tasks beyond its rated capabilities.
Solution: Monitor the compressor’s load and ensure it is operating within its specified capacity. If production demands exceed the compressor's capabilities, consider upgrading to a larger compressor or adding an additional unit to share the load.
7. Faulty Thermostatic Valve
The thermostatic valve controls the oil temperature by regulating the flow of oil through the cooler. A faulty thermostatic valve can result in inadequate cooling, leading to overheating.
Solution: Inspect the thermostatic valve for proper operation. If it is not functioning correctly, replace it to ensure proper regulation of oil temperature.
8. Blocked or Damaged Aftercooler
The aftercooler reduces the temperature of the compressed air before it enters the storage tank or distribution system. A blocked or damaged aftercooler can impair the cooling process, causing the compressor to overheat.
Solution: Inspect the aftercooler for blockages or damage. Clean the aftercooler fins and ensure that there is no debris obstructing airflow. Replace the aftercooler if it is damaged.
9. Electrical Issues
Electrical problems, such as faulty wiring, overloaded circuits, or malfunctioning components, can cause the compressor to overheat and shut down.
Solution: Inspect the electrical system for any signs of issues. Check wiring connections, circuit breakers, and electrical components. Address any problems by repairing or replacing faulty electrical parts.
