To supply compressed air for various kinds of machinery and equipment, screw compressors are widely employed in a variety of industrial applications. Although these compressors are extremely efficient and dependable, they are still subject to wear and tear over time like any other mechanical equipment.

Knowing the typical warning signals of a failing screw compressor is crucial if you use one since it will help you avoid unplanned downtime and expensive repairs. In this article, we’ll go through how to recognize a screw compressor failure and what to do next. Moreover, you can choose to have a perfect screw compressor from wenanorsc.com.

Common Signs of a Failed Screw Compressor

There are several indications when a screw compressor is failing. Common indications of a failing screw compressor include:

Unusual Noises

Unusual noises are listed among the most obvious symptoms of a failing screw compressor. Grinding, knocking, clanking, whistling, hissing, rattling, or vibrating sounds are some examples of these noises. Investigate the situation right away and fix it if your compressor is making any strange noises.

Increased Energy Consumption

Unusually high power usage or unexpected increases in energy costs could be signs that the compressor is having trouble maintaining the proper air pressure. Increased energy use can cause the compressor to wear down faster and eventually develop more serious issues if it is not addressed.

Oil Leakage or Discoloration

In a compressor, the oil is in charge of lubricating the internal parts and reducing wear and tear. The compressor may be suffering problems including low oil pressure, or contamination if the oil is spilling or appears to be tainted. To prevent serious harm, concerns with oil leakage or discoloration must be resolved as soon as possible.

Reduced Performance

The reduced performance may manifest in different ways, such as decreased flow rate, reduced pressure, longer compressor cycles, or failure to reach operating pressure. If you notice any of these performance issues, it is essential to investigate the cause and address the problem promptly to avoid further damage to the compressor.

Overheating or High Temperature

A screw compressor that is failing is indicated by an overheating compressor. Numerous factors, including low oil pressure, tainted oil, and broken cooling systems, can contribute to overheating. To prevent further harm to the compressor, you must repair the issue right away if you see that it is running hot or generating heat.

Unusual Vibration or Movement

Unusual vibration or movement may potentially be a symptom that a screw compressor is failing. It’s possible that problems like misaligned or worn bearings, imbalanced rotors, or worn belts are to blame for the vibration or movement. Investigate the cause and take action right away if you notice any strange vibration or movement coming from your compressor.

Faulty or Malfunctioning Controls

Finally, damaged or malfunctioning controls may manifest themselves in a failed screw compressor. Any flaws with the controls in a compressor might cause serious problems because they are in charge of regulating the compressor’s operation. Investigate the root of the issue and take fast action if you realize that the controls are not working properly.

What Should Do When A Screw Compressor Fails?

If you suspect that your screw compressor has failed, it is crucial to take immediate action to prevent further damage and costly repairs. You can follow these steps:

  • Shutting down your compressor as soon as you fear it has failed should be your first course of action. Running a broken compressor can result in more damage and expensive repairs.
  • Check the compressor for any indications of damage or malfunction after turning it off.
  • Call a reputable compressor service provider if you are unsure of the reason for the issue or how to resolve it.
  • The expert might advise replacing or fixing the compressor, depending on how serious the issue is.


Many industrial processes depend on screw compressors, and their failure can result in unanticipated downtime and expensive repairs. By knowing the common signs of a failed screw compressor, you can take proactive steps to prevent the compressor from damage and make sure that the equipment is running efficiently.
