The oil is always in the best condition:

Correct selection of lubricating oil - it is necessary to consider these characteristics of lubricating oil: proper viscosity characteristics, good oxidation resistance stability, good demulsibility and foam resistance, and low residual carbon value.

Prevent oil shortage - although the lubricating oil system is a closed circuit for the air compressor, there is still a small amount of oil discharged through the discharge system of the air compressor. Before starting the china rotary screw type air compressor every day, it is recommended to check the oil level with a dipstick or a mirror. If it is insufficient, fill it in time. If the frequency of refueling is found to be beyond the reasonable range, it may be a symptom of the problem - insufficient operating/ambient temperature or oil leakage. Running the air compressor under the condition of oil shortage will certainly burn or wear parts and non-wear parts prematurely.

Pay attention to overfilling - the air compressor should not be short of oil, but should not be overfilled. If the lubricating oil is excessive, it will increase the oil filtering burden of downstream components, and the oil content of compressed air will increase. Therefore, it is recommended to drain some oil if it is overfilled.

When we pay attention to the lubrication of the air-compressors itself, we should not forget the motor bearing. The freely rotating bearing can make the air compressor run smoothly and effectively convert electric energy into air pressure. Regularly add lubricating grease to the drive motor bearing of the air compressor to protect the electricity.

The machine bearing is free from the influence of overheating, friction and impact, which will lead to bearing rust and deformation.

Control temperature and prevent high temperature

More than 80% of the electric energy consumed by the air compressor is converted into heat energy, which is the enemy that affects the service life and efficiency of the compressor. Therefore, the air compressor needs to use various heat dissipation systems to reduce the temperature of each important part of the equipment.

Timely cleaning and maintenance screw air compressor parts can prevent the extreme temperature of the system from affecting the performance. The high temperature of the air compressor is caused by equipment failure and the ambient temperature is increased. Therefore, in summer, it is necessary to pay close attention to the operation of the cooling system of the air compressor to ensure its good operation.

Water cooling units, whether open or closed cycle, or external water sources, need to check their water supply regularly. Check not only the source water temperature (especially in summer), but also the circulating water quality. If the hardness and turbidity of the circulating water are high, it will cause scaling and corrosion. If the microorganism in the water exceeds the standard, some bacteria will produce dense mucus, form biological slime, and attach to the pipeline, resulting in insufficient cooling water or reduced heat exchange efficiency, resulting in high temperature of the air compressor.
