Regardless of the potential cause, an electrical overload should always be taken seriously and addressed immediately for the sake of safety.
However, a motor overload or tripped breaker can often be indicative of more serious problems – such as deficiencies in a facilities’ electrical system or increased mechanical friction in the air compressor. Sometimes the issue can be resolved quickly with a minor adjustment by an authorized professional. If a compressor shuts down due to this fault, the root cause should be investigated immediately. Most industrial air compressors are equipped with a safety shutdown that will stop the unit automatically in the event motor amperage exceeds the acceptable range. GEORGE SAEZ, SERVICE MANAGER, SULLAIR OF HOUSTON 3. Also, you can check vibration on the motor the same as the air end, detects early vibration issues, misalignments, soft foot, etc. This service improves the early detection of irregular vibration due to misalignment, or failing bearings, etc. A vibration analysis program is highly recommended from the start on all equipment as this sets the baseline vibration, then you can trend from there.

If a specific noise cannot be identified or corrected, call a professional service company for troubleshooting and repair. Bearing noise should always be addressed right away, and any unexplained clicks, rattles, or rumbles can forewarn a larger problem on the horizon. Any change in operating noise should be investigated immediately. While improving technology has enabled many compressor OEMs to reduce the overall operating noise of newer models, end users of compressed air should be familiar with the typical operating noise of their compressors during normal conditions. Many industrial air compressors – especially older models – emit high operating noise. Closely monitoring lubricant condition through a formal oil sampling program is a good strategy for preventing compressor failure and downtime. Additionally, the condition of a compressor’s lubricant can greatly affect the machine’s ability to operate at a safe temperature. Regular cleaning of a compressor’s coolers should be incorporated into any maintenance program. A sudden or unexplained rise in compressor operating temperature is a strong indicator that a problem is imminent. The physical act of compressing air molecules produces huge amounts of it (known as the “heat of compression”), and the effective dissipation of this heat is critical for safe and reliable compressor operation. HIGH OPERATING TEMPERATUREĪll air compressors fight a constant battle against heat. Air compressor operators should be on the lookout for any of the following potential warning signs, and be ready to take immediate action to limit potential failures, downtime and repair costs: 1.
Fortunately, most potential or impending issues show early warning signs that are easy to spot by a knowledgeable compressed air user. An air compressor that is operating below its design capabilities can be inefficient, costly, and even dangerous. Knowledge of machine performance, operating characteristics, and service requirements enables the user to recognize when a specific machine requires attention. It is important for compressed air users to be familiar with their industrial air compressor maintenance needs.
