In cold temperatures, which factors should be considered when selecting Air Compressor Oil?

Main body

Winter management of air compressor lubricating oil is very important, because the low temperature environment will have a certain impact on the performance of lubricating oil. The following is the expert to provide you with winter air compressor oil management advice:

What are the effects of low temperature environment on air compressor oil?

1. Less liquidity

Low temperature will lead to an increase in the viscosity of air compressor oil, making it less fluid when cold starting. This can lead to insufficient lubrication when the lubrication system is started, delaying the air compressor from reaching critical components and increasing the risk of mechanical wear.

2. Lubricating effect decreases

Due to the change in the viscosity of air compressor oil, its lubrication effect may decrease in low temperature environment. The film formed by air compressor oil at high temperatures and pressures may become thin or fail to form at low temperatures, resulting in increased friction and wear.

3. Stress drops

The low temperature environment will increase the viscosity of air compressor oil, thereby increasing the work load. If there is not enough pressure to circulate the oil, it will lead to reduced lubrication system performance.

How to manage air compressor oil in winter?

1. Choose air compressor oil suitable for low temperature environment

Low temperature air compressor oil usually has good low temperature fluidity and viscosity stability, and can still maintain good lubrication performance at low temperatures. The appropriate air compressor oil model and specification should be selected according to the use environment of the compressor to avoid equipment failure due to the inadaptability of the air compressor oil.

2. Add and replace air compressor oil

In the low temperature environment in winter, the viscosity of air compressor oil will increase, resulting in poor fluidity and affecting the lubrication effect. Therefore, it is necessary to add and replace air compressor oil in time according to the viscosity of air compressor oil and the operation of the equipment. When replacing the air compressor oil, it should be carried out in accordance with the maintenance manual and operating procedures of the equipment to ensure that the replaced air compressor oil meets the requirements.

3. Preheat air compressor oil

Before using the air compressor in winter, you can consider preheating the air compressor oil. Preheating air compressor oil can improve the fluidity and lubrication effect of oil, and reduce the starting friction and wear of equipment. The method of preheating can be to place the air compressor oil in a warm room, or use preheating equipment to heat the air compressor oil. The temperature of the preheating air compressor oil can be adjusted according to the requirements of the compressor and the ambient temperature.

4. Regularly check the quality and status of air compressor oil

You can understand the use and change of air compressor oil by checking the color, transparency, viscosity and acid value of air compressor oil. If the air compressor oil is found to be abnormal, such as black, turbidity, emulsification or acidification, it should be replaced in time, and check the operation of the equipment to understand the abnormal cause.

5. Strengthen the maintenance and maintenance of the lubrication system

Components such as filters, oil separators and coolers of the lubrication system can be checked and cleaned regularly to ensure their normal operation. At the same time, it is also necessary to check the pipelines and interfaces of the lubrication system to prevent oil leakage or pollution. During maintenance and maintenance, the maintenance manual and operating procedures of the equipment should be strictly followed to ensure the normal operation and service life of the lubrication system.

The above measures can ensure the normal operation and performance of the air compressor lubrication system, extend the service life of the equipment, and improve the reliability of the equipment.
