The difference between air compressor oil injection machine and no oil machine

The main difference between air compressor oil injection machine and oil-free machine is reflected in the following aspects:

lubrication method:

the lubrication method of oil-free air compressor is to reduce the friction between metals by using high molecular weight polymers, thereby reducing wear, and this lubrication method is free of oil pollution.

The lubrication method of the oil-injected air compressor is to lubricate the mechanical parts by spraying grease, so that they reduce wear during high-speed friction, and at the same time provide cooling for the machine.

Scope of application:

oil-free air compressor is suitable for occasions requiring high cleanliness, such as medical, food, pharmaceutical and other industries.

Oil injection air compressor can better adapt to high strength, high temperature, high compression ratio occasions, such as industry, construction and other fields.

Maintenance costs:

oil-free air compressors do not require maintenance of lubricants, so their maintenance costs are relatively low.

The oil injection air compressor needs to change the oil regularly, and check the oil level and quality, so its maintenance cost is relatively high.

Noise:

oil-free air compressor has no noise generated by the lubrication process of oil film, and the noise of oil-free air compressor is smaller than that of oil-injected air compressor.

Cost:

the cost of oil-free air compressor is relatively high, but its maintenance cost is relatively low, which is more suitable for long-term stable use.

The cost of the fuel injection air compressor is relatively low, but its maintenance cost is relatively high, which is more suitable for short-term use.

In summary, there are certain differences between oil-free air compressors and oil-injected air compressors in terms of lubrication methods, scope of application, maintenance costs, cost and noise. It is recommended to choose the appropriate air compressor according to the actual situation to ensure the unity of work efficiency and economic benefits.
