What to Do When a Screw Air Compressor Fails to Start
October 17, 2023

Screw air compressors are widely used in various industries for their efficiency and reliability. However, like any mechanical equipment, they may encounter issues that hinder their startup. In such cases, it is important to follow a systematic approach to troubleshoot and resolve the problem. Here are some steps to take when a screw air compressor fails to start:


1. Check Power Supply: Start by ensuring that the compressor is properly connected to a reliable power source. Verify that the power cord is not damaged and that the power switch is in the "on" position. Double-check the circuit breaker or fuse box to ensure there is no tripped breaker or blown fuse.


2. Examine Control Panel: Inspect the control panel for any warning lights or error codes. Modern screw compressors are equipped with advanced control systems that provide valuable information about the cause of the startup issue. Refer to the compressor's manual to interpret the error codes or contact the manufacturer's technical support for guidance.


3. Inspect Safety Devices: Screw air compressors are equipped with safety devices to protect against potential hazards. Check if any safety devices such as pressure switches or thermal overload protectors have been activated. Resetting the safety devices may help resolve the startup problem, but it is crucial to investigate the underlying cause to prevent future occurrences.


4. Check Oil Level: Insufficient oil in the compressor can lead to startup problems. Verify the oil level using the sight glass or dipstick provided. If the oil level is low, add the recommended oil to the appropriate level. Be cautious not to overfill, as it can cause damage to the compressor.


5. Examine Air Filters: Clogged or dirty air filters can restrict airflow and hinder startup. Inspect the air filters and clean or replace them if necessary. Regular maintenance of air filters is essential to ensure the compressor's efficiency and prevent potential issues.

6. Inspect Belts and Pulleys: A loose or damaged belt can prevent the compressor from starting. Check the condition and tension of the belts. Replace any worn-out or damaged belts promptly. Similarly, examine the pulleys for any signs of wear or misalignment and rectify as needed.


7. Seek Professional Help: If the above steps do not resolve the startup issue, it is advisable to contact a professional technician or the manufacturer's service center. They possess the expertise and tools required to diagnose and repair complex problems that may be beyond the scope of basic troubleshooting.


Remember, proper maintenance and regular inspections are key to ensuring the smooth operation of a large mining air compressor. By following these steps and seeking professional assistance when necessary, you can effectively address startup problems and keep your compressor running efficiently.
