What are the reasons for the spontaneous combustion of oil-free air compressors to produce fire?

Oil-free air compressors, as a common device used by major manufacturers today, will inevitably encounter failures during use. Although the failures vary in size, they will cause losses to our production and manufacturing. Some oil-free air compressors will have an alarm mechanism, but some problems we cannot detect. Therefore, it is necessary to be familiar with the failures of oil-free air compressors and be able to handle them in a timely manner. Let’s talk about the reasons why oil-free air compressors naturally produce fire.

The reasons for the spontaneous combustion of oil-free air compressors to produce fire are as follows:

Oil used in oil-free air compressor:

Oil-free air compressor oil is very important. Whether the flash point of the oil meets the requirements, whether its antioxidant ability meets the standard, the oil is constantly changing under pressure, and the amount of vaporization of the oil is different at 80 degrees and 100 degrees. The vaporization amount at 100 degrees is 10 times that at 80 degrees. Therefore, the greater the vaporization amount of oil-free air compressor oil, the more carbon deposits will be generated. As the carbon deposits are continuously affected by the temperature of the compressor, they will continue to warm until fire is generated.

Whether the pressure maintaining valve of the oil-free air compressor is damaged:

If it is damaged, gas collision will easily occur when several compressors are used at the same time, and fire will most likely occur.

The fire generated by the collision of objects:

Objects refer to rusty iron, carbon deposits, welding, or metal particles worn out by metal parts.

A fire on an oil-free air compressor is a very serious accident. During normal operation, an air compressor will never produce an open flame. Generally, the causes of the fire on an air compressor can be divided into: oil leakage from the air compressor, electric sparks near the equipment, other open flames, abnormal oil use, compressor operation failure, motor failure, and electronic control box failure. Once the air compressor is found to produce an open flame, it is forbidden to directly extinguish the fire with water or fire extinguisher. The power supply to the equipment should be cut off first to prevent greater danger.
