What is an oil injection air compressor

Oil injection air compressor is a kind of mechanical equipment that uses electric motor to drive air compression device. Its product structure mainly includes electric motor, compression mechanism, intake system, exhaust system, cooling system and lubrication system. In the working principle, the fuel injection air compressor drives the compression mechanism through a motor to compress the air into a high-pressure state. At the same time, lubricating oil is mixed into the air during the compression process to reduce wear and cool the compression parts. The compressed air is released through the exhaust system to complete an air compression process.

Fuel injection air compressors are usually used in places that require higher pressure and higher volume, such as large industrial production lines, mechanical processing plants, etc. This type of air compressor uses lubricating oil to lubricate and cool the compressor, so it will produce a certain mixture of oil and gas, which needs to be treated before it can be discharged into the atmosphere.

The advantages of oil injection air compressor include:

the compression chamber and bearings are continuously filled with lubricating oil, which simplifies their complex mechanical structure.

Lubricating oil can lubricate and cool the equipment and help reduce noise generation.

Lubricating oil can increase air tightness and improve the volumetric efficiency of the air compressor. Under certain conditions, such as lubrication and cooling effect, noise reduction and air tightness improvement, the efficiency of oil-injected air compressors may be higher than that of oil-free air compressors.

However, the fuel injection air compressor also has some disadvantages:

oil-injected air compressors require regular inspections and replacement of belts and other accessories when necessary, and maintenance costs may be relatively high.

Compressed air contains oil, so it cannot be used in places with high air quality requirements, such as food and medical industries.

The quality of lubricating oil is high, and maintenance work such as lubricating oil replacement and filter element replacement is required regularly, and the maintenance cost is relatively high.
