Portable diesel driven air compressors are considered to be the powerhouses of air compression technology. These massive compressors are designed to be hauled behind large trucks and a common staple in both industrial and construction settings. Because of their heavy duty use, these air compressors go through a lot of wear and tear and can see their fair share of problems. Here are a few of the most common air compressor service issues that can come up.
Air Compressor will Not Start or Crank
If your diesel driven air compressor will not start--or crank at all--there could be a problem with the battery. Use a battery voltage tester to check the voltage that is being supplied by the battery. Furthermore, you should check to make sure that all battery cables are free of corrosion and secured tightly to the battery. Another cause could be a tripped safety switch. Most models are equipped with a safety switch that is designed to automatically shut down the air compressor if it overheats or pressure levels get out of hand.
Air Compressor Cranks, But Will Not Start
If the air compressor you are using will crank, but never start, it could be due to various issues. Of course, the first thing that you should do is check and make sure that there is fuel in the tank. If this is not the issue, take a moment to check the following things before calling for air compressor repair:
- Make sure the fuel filter is in good working order and replace if necessary
- Pump the fuel priming pump that is usually located on top of the fuel filter
- Vent both the high and low fuel pressure valves to remove any air
- Check the stop solenoid, which is designed to cut off fuel and can get stuck in an off position due to dirt and debris
- Check the speed setting of the air compressor
Compressor Has No Air Pressure
The majority of the the time, this is related to the air intake valve. Check control systems, inlet valves, and regulation valves to make sure that they are opening and closing as they should be to allow the flow of pressurized air. It is not uncommon for these valves to become clogged with debris and stop functioning as they should.
When you have a diesel driven air compressor, it is helpful to be able to recognize common things that can go wrong. While these are just a few of the most common air compressor problems, there are many that may require service from a professional.
