Pneumatic Troubleshooting: How To Flow Test An Air Compressor

Pneumatics System

Performing a flow test on your air compressor can help you troubleshoot issues in your pneumatic system quickly and accurately, so they can be resolved swiftly without causing disruption or downtime. A flow test is a fast and easy way to identify any problems that may be present in your air compressor, including leaks and blockages. In this article, we will provide a step-by-step guide on how to perform a flow test on your air compressor

Step 1: Tools You’ll Need

The first step is to gather the necessary supplies for the flow test. The basics you’ll need include a pressure gauge, an angled gauge adapter, a flexible hose, and appropriate fittings for connecting everything together. You may also require a digital multimeter, wrench set, vacuum gauge, screwdriver set, leak detector spray, safety glasses and gloves.

Step 2: Preparation And Safety Measures

Before beginning your flow test it’s important to take the appropriate safety measures. This includes making sure there is no power or load running through the system as well as shutting off any valves or switches that may be connected to it. Make sure all engineers, visitors, and machine operators are aware of what is going on so that everyone remains safe throughout the process. Once everything has been shut off and double checked for safety purposes then you can move onto the actual testing phase.

Step 3: Connect Your Gauges To The Air Compressor

Start by attaching the pressure gauge to the angle gauge adapter using the appropriate fittings, then attach one end of the flexible hose onto the angle gauge adapter and the other end onto the air compressor outlet port. Ensure that all connections are secure before proceeding with the next step.

Step 3: Perform Flow Test

Begin the flow test by turning on your air compressor and allowing it to reach its full operating pressure (usually around 90 PSI). Once it has reached this pressure level, take note of what pressure is displayed on your pressure gauge – this should be close to what you set as your operating pressure setting. If it is significantly lower than expected, there could be an issue with either your compressor or one of its components, which will need further investigation.

Now turn off your air compressor and wait a few minutes before performing another reading from your pressure gauge – this will allow any residual air in the lines or hoses to dissipate so that an accurate reading can be taken without interference from any remaining pressurised air. If there has been no noticeable drop in pressure during this time, then everything is functioning correctly.

However, if there has been a noticeable drop in pressure while switched off, then further testing may be required to diagnose the cause and what can be done to rectify it promptly and efficiently.
