Can excessive lubrication of air compressor valves lead to spontaneous ignition?

1. True

2. False

The correct answer is: True

Excessive lubrication of air compressor valves can indeed lead to spontaneous ignition under certain conditions. The presence of oil in high-pressure environments can create a flammable mixture, especially when temperatures rise due to the compression process. When too much lubricant is applied, it can accumulate and potentially overheat, which raises the likelihood of it igniting spontaneously. This phenomenon is particularly concerning in systems where the oil is exposed to heat generated by the compressor operation. In addition to potential ignition, excessive lubrication may also lead to inefficiencies in the compressor's performance, as too much oil can hinder the movement of internal components or cause foaming. Hence, maintaining the correct amount of lubrication is crucial not only for safety but also for optimal equipment performance.
