Energy consumption of oil-injected air compressor and oil-free air compressor

Literally, oil-free air compressors and oil-free air compressors are easy to distinguish. However, in terms of their power generation equipment and energy efficiency, they are completely different. What is the main difference?

What is the difference in energy efficiency between oil-free compressors and oil-air compressors?

From the oil content point of view, the oil and oil-free compressor generally refers to the amount of oil content of the gas discharged from the exhaust port of the compressor. Generally, the oil-free compressor has more oil content. Oil content, but less oil content, about 0.01ppm. Therefore, the oil content can be used to distinguish oil and oil-free air compressors. There is also a fully oil-free air compressor, which is not lubricated with oil but lubricated with resin materials, so the final discharge of gas without oil is called a fully oil-free air compressor.

From a structural point of view, there is no difference between oil-free air compressors and oil-free air compressors. However, from the working principle, there is a clear difference between the two.

The oil-free air compressor has no oil during operation. Whether it is an oil-free piston machine or an oil-free screw air compressor, a large amount of high temperature will be generated during operation. If there is oil in the oil-free air compressor, the high temperature generated during the compression process of the air compressor will be taken away, thereby cooling the machine.

The oil-free air compressor does not contain oil, and a large amount of high temperature may be generated during the compression process, which brings some trouble to the air compressor. How to solve such a high temperature to make the air compressor run normally?

In fact, the oil-free air compressor uses water to lubricate the air compressor head, instead of oil to solve the high temperature problem in the air compressor compression process, so as to achieve the purpose of oil-free compression.

To some extent, oil-free air compressors are cleaner and more environmentally friendly than oil-based air compressors. Therefore, hospitals, laboratories, schools and other institutions. Ideal for use with oil-free air compressors. These enterprises and institutions also prefer to use oil-free air compressors.
