What are the most common problems with rotary screw compressor maintenance?

The most common problems we see in rotary screw compressor maintenance include the following: One of the critical elements of maintenance is adjusting service intervals to allow for a more challenging environment. In a cement plant, for example, the dust and dirt quickly build up in air and oil filters, so you will want to change them more often.

What is rotary screw air compressor oil?

Air compressor oil plays several vital roles within a rotary screw air compressor system: Rotary screw air compressors are sometimes “oil flooded” or “oil injected,” describing that oil is injected into the rotor housing. The oil mixes with the air during compression but is separated back out before the compressed air leaves the system.

How do you maintain a rotary screw air compressor?

To keep your compressor motor operating efficiently, you’ll want to ensure the grease is changed at manufacturer-recommended intervals and swap out motor couplings or belts as they begin to show wear. To keep your rotary screw air compressor in top shape, you should inspect couplings or belts and replace as needed.

How do I change the oil on my air compressor?

When changing your air compressor’s oil, follow the instructions in your manual. Although the basics of an oil change are simple—drain the old oil and then pour in new oil—the individual steps can be significantly more detailed. As an example, here are the steps required to change the oil in VMAC’s G30 gas powered air compressors:

How do I Check my air compressor oil level?

Check your air compressor oil level daily, or every time you use the air compressor. To check the oil level, follow these simple steps: Ensure the vehicle is parked on level ground and that the compressor system is depressurized and cool to the touch. Check the oil level in the sight glass.

What is air compressor oil?

Air compressor oil is standard or synthetic oil made specifically for air compressors. Unlike motor oil, air compressor oil does not contain detergent and typically has lower amounts of carbon, sulfur, and other contaminants that can cause build-up.
