Oil-free and oil-free compressors

Oil-free compressors and oil-free compressors are two different types of compressors, which are significantly different in terms of working principle, operating environment and maintenance.

1. working principle

oil-free compressor: No lubricating oil is used in the compression process, so the compressed air quality is relatively high and does not contain oil and gas. It usually uses special materials and designs to reduce friction and wear, thereby ensuring normal operation without lubricating oil.

Oil compressor: Lubricating oil is used to lubricate the moving parts of the compressor, such as the crankshaft, cylinders, valves, etc., during the compression process. Lubricating oil can fully reduce friction and wear, and improve the efficiency and service life of the compressor.

2. use environment

oil-free compressor: Because the compressed air does not contain oil and gas, it is very suitable for scenarios with high air quality requirements, such as medical, food, pharmaceutical and other industries. In addition, in some experiments that require high-purity gas, oil-free compressors are also the first choice.

Oil compressor: Because of its good lubrication and cooling effect, oil compressor is widely used in industrial refrigeration and air conditioning system. It is suitable for harsh working environments and occasions that require long-term continuous work.

3. maintenance

oil-free compressor: Since there is no lubricating oil that needs to be replaced and cleaned regularly, its maintenance is relatively simple. However, it should be noted that the grease in the bearing may evaporate and oxidize and decompose due to temperature rise during long-term operation, and it is necessary to check and replenish the grease regularly.

Oil compressor: The lubricating oil and oil filter need to be replaced regularly to ensure the normal operation of the compressor. At the same time, it is necessary to regularly check the oil level and oil quality to ensure the normal operation of the lubrication system.

In summary, oil-free compressors and oil compressors have their own characteristics and applicable scenarios. When choosing, it is necessary to determine which type of compressor to use according to specific use requirements and environmental requirements.
