Introduction
Air compressor oil keeps industrial compressed air systems reliable. It lubricates moving components and protects the compressor’s internal parts from damage, and even helps dissipate heat from your system. But over time, compressor oil may degrade due to exposure to heat, moisture, dust, and stress, making the compressor more vulnerable to overheating and performance issues.
This is where regular oil changes become ever more important. Many facilities simply wait until the compressor manufacturer’s recommended oil change schedule, but changing operating conditions and warning signs may prompt you to perform oil changes earlier than scheduled. This guide will walk you through the most common signs that your compressor oil needs changing, and how Compresstech Resources, a trusted air compressor oil supplier in the Philippines, can help you with this issue.
Signs Your Air Compressor Oil Needs Changing
Below are seven signs that can help you identify potential problems and determine when inspection or compressor oil replacement may be necessary.
Sign #1: Overheating
Normal discharge air temperatures in oil-injected rotary screw compressors, the most commonly used industrial compressor type, range from 77 to 93 °C (170 to 200 °F), while normal lubricant temperature goes from 65 to 80 °C (149 to 176 °F). If you notice higher operating temperatures than these ranges, your compressor oil may have aged and lost some of its ability to lubricate or transfer heat.
Note, however, that the compressor oil might not be the sole reason for overheating. You should also check for dirty coolers or ventilation problems to see if they’re the cause of your unit’s overheating.
Sign #2: Unusual Noises
If you hear grinding, rattling, knocking, or other unfamiliar sounds in your air compressor, there might be an oil-related problem that needs fixing. For example, when your compressor oil has degraded or depleted, its moving components may experience increased friction that causes abnormal noise. When this happens, changing oil in your air compressor may be the right solution.
However, loose components, bearings, or other mechanical faults can also produce similar noise. Make sure to inspect your compressor parts immediately to avoid overall machine failure.
Sign #3: Foul or Burning Smell
A strong burnt-oil smell around your compressor may indicate that the lubricant has been exposed to excessive heat or has begun to oxidize. This may be caused by prolonged use of the equipment at elevated temperatures. Contaminated oil and inadequate cooling may also contribute to the problem.
When an unusual burning odor develops, investigate the cause first. Check your operating temperatures, ventilation, oil levels, and the equipment’s maintenance history. If the lubricant has deteriorated, a compressor oil replacement may be the best way to address the problem. If the smell is accompanied by smoke, an alarm, or signs of overheating, stop the equipment and follow the manufacturer’s safety procedures.
Sign #4: Compressor Fluctuations
In an oil-lubricated compressor, deteriorated lubricant can increase the friction between moving parts and ultimately affect its efficiency. When your compressor frequently starts and stops, struggles to maintain its usual operating pattern, or behaves differently under comparable workloads, an oil change may be a solution, but these symptoms can also result from other mechanical issues.
To address compressor fluctuations, make sure to review operating data and inspect the lubricant to narrow down the cause.
Sign #5: Pressure Loss
A well-designed air compressor system experiences up to 10% pressure drop between the compressor and the discharge outlet. Any pressure loss higher than that can affect your production and the performance of the equipment connected to your compressed air network.
In oil-lubricated rotary screw compressors, aged oil may not perform well in sealing clearances between internal components, causing leaks that result in pressure losses. So, if the pressure falls below the normal operating range, inspect the system for leaks and check the oil level and condition.
Sign #6: Oil Leaks
If you see visible oil buildup around the compressor, its connections, or the surrounding area, there may be a leak that needs immediate attention. Leaks don’t necessarily mean the lubricant has deteriorated, but they can lower your compressor’s oil level and compromise the equipment if left unresolved.
If the compressor has lost a significant amount of oil, determine the cause of the leak first before returning to normal operation. When replenishment is needed, use only the lubricant specified by your trusted air compressor oil supplier to keep your compressor in optimal condition.
Sign #7: Energy Consumption Spikes
A noticeable increase in electricity consumption without a relative increase in your facility’s compressed air demand may signal that the compressor is operating suboptimally. When your compressor has degraded oil and experiences more friction in its internal parts, the compressor is forced to use up more energy than required to maintain normal operations, hence spiking your consumption. Changing oil in your air compressor may be the best solution in this situation.
