Maintenance Tips for Compressed Air Treatment Systems
Compressed air treatment systems are used in a variety of heavy industries. This is especially true in manufacturing and food processing environments, where air should be 100% contaminant-free. Even if there’s no evident issue, scheduled maintenance should always be a top priority.
Failure to maintain compressed air equipment could lead to contaminated products and costly downtime. What’s more, it could cause your compressor to work overtime and increase your energy bills.
Here’s a brief compressor maintenance guide with a list of jobs to tick off. Our compressed air engineers have also supplied a maintenance schedule for rotary screw compressors. Read on to find out more…
Monitor compressor controls
Your compressor’s control system is a key indicator of how well your unit is running. It keeps track of power output, and adjustments can be made as and when needed, so it’s important to keep an eye on the main controls, including:
- Pressure gauges
- Temperature indicators
- Switches
- Safety devices
In particular, pay attention to any unusual noises or fluctuations, as these can signal potential issues such as air leaks and blockages. By spotting these issues early, the likelihood of breakdowns and energy wastage is reduced.
Check the compressor temperature
During the summer months, keep an eye on your compressor’s temperature. Make sure the unit is placed somewhere with good ventilation, as restricted airflow can put high pressure on the equipment – and even impact energy costs. If it overheats, the compressor could break down and need time out for repairs.
Check for clogged filters
Filters act as the first line of defence against incoming contaminants. While they’re designed to trap heavy loads, in time, they can become clogged with debris and moisture. As a result, airflow is reduced. By regularly checking filters, you’ll identify those that need replacing to maintain the system’s efficiency.
Check the belt
Be sure to visually inspect the belt for signs of wear and listen out for squealing noises that may indicate slipping. Most manufacturers provide guidance on the correct tension to aim for. It may be that the belt needs lubricating or replacing as necessary.
Industrial compressor maintenance for rotary screw compressors
Below are the basic operator checks you should be completing for a rotary screw compressor in between your annual service:
Daily Checks:
- Check the Oil Level: Check the sight glass while the machine is off (or per manufacturer instructions) to ensure the oil is in the safe zone.
- Read the Display Panel: Check for red warning lights, service symbols, or error messages.
- Listen & Look: Note if the compressor sounds unusually loud or if there are new puddles of oil or water underneath.
- Moisture Drains: Check the auto-drains on the receiver tank and filters to ensure water is discharging correctly.
Weekly Checks
- Operating Temperature: Check the screen while running to see if the unit is operating hotter than usual.
- Air/Oil Leaks: Listen for continuous hissing sounds or check for fresh oil mist on the side panels.
Monthly Checks
- Ventilation: Ensure cooling grills and room ventilation louvres are not blocked. The machine needs proper airflow.
- General Cleanliness: Wipe down the outside panels. A clean compressor makes it much easier to spot new leaks before they lead to a breakdown.
Important Rule of Thumb: If you spot an oil leak, a warning light, or a strange noise, call Air Supply Manchester immediately (+44(0)161 5183440) so our engineers can resolve the issue before it impacts production.
