What Is the Role of Oil in Lubricated Screw Compressors?

In lubricated screw compressors, oil plays a crucial role in ensuring optimal performance, reliability, and longevity of the compressor. Here’s a detailed explanation of the role of oil in lubricated screw compressors:

Lubrication: One of the primary functions of oil in screw compressors is to provide lubrication to the moving parts, particularly the screw rotors. The oil forms a thin film between the rotors and the compressor housing, reducing friction and wear. This lubrication minimizes mechanical losses and helps maintain efficient operation by reducing energy consumption.

Sealing: Oil also acts as a sealing medium in lubricated screw compressors. The oil film created between the rotors and the compressor housing helps create a seal, preventing air or gas leakage between the high-pressure and low-pressure sides of the compressor. This sealing action is crucial for maintaining the compressors’ efficiency and preventing losses in compression performance.

Cooling: Oil plays a vital role in cooling various components of the screw compressor. As the compressed air or gas is compressed, it generates heat. The oil absorbs a significant amount of this heat and carries it away from the compression chamber. The oil then circulates through the compressor’s oil cooling system, where it dissipates the heat to the surrounding environment or through an oil cooler. Efficient oil cooling helps prevent overheating of the compressor components, ensuring reliable operation and extending the compressor’s lifespan.

Cleaning: The oil in lubricated screw compressors acts as a cleaning agent. It carries away contaminants, such as dirt, dust, and metal particles, that may enter the compressor during operation. The oil passes through filters and separators, removing these impurities and preventing them from accumulating in the compressor’s internal components. Clean oil helps maintain the integrity of the compressor’s internal parts and reduces the risk of damage or malfunctions.

Sealing Element Lubrication: In some lubricated screw compressors, the oil also serves to lubricate the sealing elements, such as the shaft seals or labyrinth seals. Proper lubrication of these seals helps maintain their effectiveness in preventing oil leakage and maintaining the separation between the oil and the compressed air or gas.

Corrosion Protection: Oil in screw compressors often contains additives that provide corrosion protection to the internal components. These additives form a protective layer on the metal surfaces, preventing corrosion caused by moisture or contaminants present in the compressed air or gas. Corrosion prevention helps maintain the compressor’s performance, efficiency, and reliability over time.

It’s important to note that lubricated screw compressors require regular oil monitoring, oil analysis, and oil changes to ensure optimal performance. The oil level, quality, and viscosity should be regularly checked and maintained within the manufacturer’s recommended specifications.

In summary, oil in lubricated screw compressors serves crucial functions such as lubrication, sealing, cooling, cleaning, sealing element lubrication, and corrosion protection. These functions collectively contribute to the efficient and reliable operation of the compressor, extending its service life and minimizing maintenance requirements.
