Air compressors have strict requirements on the selection of lubricating media. The following three types of oil products may have a negative impact on equipment operation and output air quality due to their improper performance. Special attention should be paid to avoid use:
1. Ordinary engine oil (such as automobile oil)
The design goal of this kind of oil is to reduce friction and high temperature oxidation of power equipment, but it lacks the anti-emulsification and high temperature stability of compressor-specific oil. Long-term use may cause oil to decompose at high temperatures, produce sludge or carbon deposits, block the oil circuit or affect the lubrication efficiency of components; at the same time, its additives may not be able to effectively separate the water generated during compression, resulting in the formation of emulsion after oil and water mixing, reducing equipment Sealing and increase the risk of corrosion.
2. Hydraulic
oil Although hydraulic oil has certain viscosity characteristics, its core function is to transmit power rather than long-term lubrication. During the operation of the compressor, the viscosity of the hydraulic oil may decrease due to high temperature, and a stable oil film cannot be formed, which aggravates the wear of the components; in addition, its anti-foaming and anti-oxidation properties are weak, and long-term use is easy to produce bubbles or oil aging, which affects the operation stability of the equipment.
3. Gear
oil Gear oil is mainly used for gear box lubrication, its extreme pressure wear resistance is strong, but the high temperature volatility and oxidation resistance may be insufficient. When the compressor is running, the gear oil may volatilize due to the increase in temperature and pollute the output air; at the same time, its additives may not be able to effectively cope with the high-frequency reciprocating motion of the compressor, accelerate the deterioration of oil quality and increase the maintenance frequency.
Use recommendations
In order to ensure the stable operation of the air compressor and the cleanliness of the output air, 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.
