Does the screw air compressor need lubricating oil?

Screw air compressor does need lubricating oil. Screw air compressor with its high performance, high efficiency, maintenance-free, highly reliable and other advantages for all walks of life to provide high-quality compressed air. However, in the working process of the screw air compressor, many factors such as equipment speed, suction state, gas leakage, cooling effect and so on may affect its actual displacement, and may lead to equipment aging, corrosion and slow power. Therefore, in order to maintain the normal operation of the screw air compressor and prolong its service life, it is essential to use suitable lubricating oil for maintenance.

Lubricating oil mainly plays the following roles in screw air compressor:

1. reduce wear: Lubricating oil can form a protective film between the friction surfaces to prevent direct contact between metal parts, thereby significantly reducing friction and wear.
2. Cooling effect: Lubricating oil can reduce the heat generated by friction, help keep the temperature of the machine stable, and prevent overheating from causing damage to the equipment.
3. Corrosion protection: Lubricating oil can prevent air and water from eroding the air compressor parts and prolong the service life of the equipment.
4. Cleaning function: Lubricating oil helps to remove pollution particles in the system and keep the lubrication system clean.
5. Sealing effect lubricating oil can prevent gas leakage and the entry of external impurities, and ensure the sealing performance of the air compressor.
6. Noise control lubricating oil can reduce the noise generated by metal friction and provide a quieter working environment.

When selecting and using lubricants, you need to pay attention to the following points:

1. choosing the right lubricant: The appropriate lubricating oil should be selected according to the model, working conditions and use environment of the screw air compressor. Usually, the screw air compressor manufacturer will provide recommended lubricant models and specifications.
2. Regularly replace lubricating oil: Lubricating oil will gradually be contaminated, oxidized and degraded during use. Therefore, it is necessary to change the lubricating oil regularly according to the manufacturer's recommendations or actual usage. Generally speaking, the replacement cycle may be about 2000-3000 hours, but the specific cycle will be affected by many factors, such as workload, intake air quality, exhaust temperature, etc.
3. Pay attention to the storage and replacement of lubricating oil: Lubricating oil should be stored in a dry, clean, well-ventilated place, avoid direct sunlight and high temperature. When replacing the lubricating oil, ensure that the old oil is completely drained and the relevant parts are cleaned to avoid contamination of the new oil.

In summary, the screw air compressor needs lubricating oil to maintain its normal operation and extend its service life. Proper selection and use of lubricants is essential to ensure compressor performance and reliability.
