Air compressor oil and ordinary oil in the functional positioning of the existence of essential differences, can not be simply equivalent. The following is a brief description of the core differences from the design principles and usage scenarios:
Basic functional differences
Ordinary engine oil (such as engine lubricating oil) mainly serves the lubrication requirements of power transmission equipment, focusing on reducing friction of metal parts, reducing operating temperature, and having certain cleaning and anti-rust capabilities. The special oil for air compressors needs to meet the special requirements of the compression process at the same time: maintain stable lubrication under high temperature and high pressure environment to avoid oil decomposition due to temperature rise; at the same time, it needs to have good anti-emulsification property to prevent the mixing of water and oil generated in the compression process to form emulsion, which affects the sealing performance and operation efficiency of the equipment.
Theadaptation scenario limits
the working principle of the air compressor (such as screw type and piston type) to put forward higher requirements on the performance of the lubricating medium. The special oil needs to have lower volatility to reduce the risk of oil discharge with compressed air at high temperatures; at the same time, it needs to control the appropriate viscosity to ensure that an effective oil film is formed at the moment of compressor startup to avoid dry friction of components. Ordinary oil may not be able to meet these characteristics at the same time due to different design objectives. Long-term use may lead to a decrease in compressor efficiency, an increase in maintenance frequency, and even affect the cleanliness of the output air.
Use recommendations
In order to ensure the stable operation of the air compressor and the output air quality, it is recommended to use the special oil recommended by the equipment manufacturer. After targeted research and development and testing, this kind of oil can be adapted to the working parameters of specific models (such as compression ratio and exhaust temperature), which can prolong the service life of the equipment and reduce the risk of failure caused by oil quality mismatch.
In short, the special oil for air compressors is a professional lubricating medium designed for the special needs of the compression process. It is significantly different from ordinary oil in terms of functional positioning and performance requirements and cannot be replaced at will.
