Air Compressor Troubleshooting Chart: Your Ultimate Guide to Diagnosing Issues
For numerous industries, such as manufacturing, construction, and vehicle repair, air compressors are crucial instruments. They function by compressing air to power various tools and equipment. Air compressors can, however, experience issues over time, just like any other piece of machinery. Technicians frequently utilize air compressor troubleshooting charts to identify these problems. The definition, significance, and practical application of air compressor troubleshooting charts will all be covered in this article.
Air compressor types
It’s critical to comprehend the two primary types of air compressors:
- Positive displacement, and
Before we get into diagnostic charts, in order to compress the air, positive displacement air compressors trap it in a chamber and then reduce its volume. Reciprocal, rotary screw and scroll compressors are a few types of positive displacement air compressors. On the other hand, roto-dynamic compressors operate by giving the air a velocity before translating that velocity into pressure. Centrifugal and axial compressors are two types of roto-dynamic compressors.
Common Air Compressor Problems
Many issues, such as low pressure, high pressure, leakage, overheating, and odd noises, can arise with air compressors. High pressure can be the result of a broken safety valve or a clogged discharge pipe, whereas low pressure is frequently brought on by a malfunctioning pressure switch or a clogged air filter. While overheating might be brought on by a lack of lubrication or a filthy cooling system, leakage can happen as a result of worn-out gaskets or loose fittings. Strange noises may be a sign of a faulty piston, worn bearings, or a loose belt.
