1. Increase the upper pressure limit to the customer's desired setting, ensuring it remains within the rated pressure range of the compressor.
2. Access and remove the screw air compressor's intake valve for inspection or replacement with a complete repair kit.
3. Identify and eliminate any air leaks in the system to ensure optimal performance.
4. Advise customers to check the entire pipeline for potential air leakage. If no leak is found, consider increasing the capacity of the screw air compressor if needed.
5. Perform a thorough overhaul of the pressure switch. If it cannot be repaired, replace it with a new unit.
6. Inspect the differential pressure across the oil separator. If it exceeds 0.8–1 kg, replace the oil separator with a new one.
7. Remove and service the load solenoid valve. If it is damaged or not functioning properly, replace it with a new component.
8. Adjust the drive belt tension as required. If the belt is worn or damaged, replace it immediately to avoid further issues.
9. Replace the intake coupling if it shows signs of wear or damage.
10. Install a new synchronous motor if the existing one is faulty or inefficient.
11. Clean or replace the air filter if it becomes clogged. Regular maintenance of the air filter ensures better airflow and efficiency.
12. Adjust the computer settings to calibrate the pressure transmitter accurately. If the transmitter is malfunctioning, replace it with a new one to ensure reliable readings.
This comprehensive maintenance guide ensures that the screw air compressor operates efficiently and safely. Regular checks and timely repairs can significantly extend the lifespan of the equipment and reduce downtime. Always follow manufacturer guidelines and safety protocols when performing any maintenance tasks.
