How to Control the Oil Temperature in Screw Air Compressors

Maintaining the correct oil temperature is crucial for the proper functioning of винтовые воздушные компрессоры. Statistics show that the ideal operating oil temperature ranges between 80°C and 90°C. If the oil temperature drops below 40°C or exceeds 90°C, the oil’s quality can deteriorate, leading to potential damage and reduced compressor life.

When the oil temperature is too low (below 40°C), the oil becomes too viscous, causing increased friction within the compressor. This not only hinders the lubrication process but also leads to the buildup of carbon deposits, which can result in fire or explosions in extreme cases. Conversely, when the oil temperature exceeds 90°C, the oil may oxidize, reducing its viscosity and lubricating properties. This leads to poor lubrication and faster wear of the compressor components.

Oil temperatures may fall below optimal levels, especially in colder weather. Common causes include:

• Low ambient temperatures: Cold weather can result in lower oil temperatures.
• High viscosity oil: Using oil with high viscosity in colder conditions.
• Infrequent compressor operation: If fewer compressors are running, the oil may not be heated adequately.
• Low discharge pressure: This can prevent the compressor from reaching its optimal operating temperature.

High oil temperatures are more common during the warmer months and can result from several factors, including:

• Высокие температуры окружающей среды: Warmer weather naturally increases the oil temperature.
• Ineffective cooling: High temperatures of the circulating cooling water, blocked coolers, or insufficient airflow around the compressor can cause oil temperatures to rise.
• High discharge pressure: If the discharge pressure is too high, it forces the compressor to work harder, increasing oil temperature.

To prevent the oil temperature from dropping too low and causing inadequate lubrication, consider the following strategies:

1. Improve building insulation and heating: Insulate the compressor room to maintain a warmer environment and reduce the flow of cooling water to decrease the efficiency of the oil cooler.
2. Continuous operation: Run 1-2 compressors continuously to generate heat through friction, naturally raising the oil temperature.
3. Use low-viscosity oil: During winter months, use oil with lower viscosity to ensure proper flow and lubrication.

To avoid damage caused by excessively high oil temperatures, you can take the following actions:

1. Improve ventilation: In hot summer months, open windows and vents to improve airflow around the compressor. Consider using cooling water to periodically cool the compressor room floor.
2. Lower cooling water temperature: Ensure the circulating cooling water is at the correct temperature. If it’s too warm, the oil cooler won’t work effectively, so implement cooling measures for the water system.
3. Check oil quality: If you notice the oil becomes thinner or discolored (milky or white), it may be time to replace the oil or add fresh oil. Lower viscosity oil should be replaced immediately.
4. Regular maintenance of the oil cooler: Periodically inspect and clean the oil cooler to ensure proper heat exchange. Blocked coolers reduce cooling efficiency and may cause oil temperature to rise.

Controlling the oil temperature in винтовые воздушные компрессоры is essential for maintaining optimal performance and extending equipment life. Focus on three main factors to ensure your compressor operates efficiently:

1. Oil quality: Ensure that the oil used is of the correct grade and in good condition.
2. Cooling system efficiency: Regularly check and clean the cooling system to maintain optimal temperature control.
3. Environmental conditions: Monitor the temperature and pressure in the operating environment to prevent excessive heat buildup.

By paying attention to these factors, you can ensure your screw air compressor operates smoothly and efficiently.
