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.

In medical applications, it is crucial to ensure the purity of the compressed air. Screw compressors can be designed and certified to provide oil-free air, eliminating the risk of oil contamination in the medical air supply. Oil-free screw compressors incorporate specialized sealing systems and filtration to prevent oil carryover, making them suitable for medical air applications.

3. Air Quality Standards:

Medical air must meet specific air quality standards to ensure patient safety and treatment effectiveness. Standards such as the European Pharmacopoeia (Ph. Eur.) or the United States Pharmacopeia (USP) define the required purity levels for medical air, including limits on particulate matter, moisture content, and microbial contamination. Screw compressors can be equipped with appropriate filtration and purification systems to meet these standards.

4. Integrated Drying and Filtration:

Some screw compressors designed for medical air applications incorporate integrated drying and filtration systems. These systems remove moisture and contaminants from the compressed air, ensuring it meets the required quality standards. Integrated drying systems can include refrigerated dryers, desiccant dryers, or membrane dryers, depending on the specific needs of the medical air supply system.

5. Redundancy and Backup Systems:

Medical air supply systems often require a high level of reliability and continuity. Screw compressors can be configured with redundancy and backup systems to ensure uninterrupted supply. Multiple compressors can be installed in parallel, with automatic switching mechanisms to maintain supply in case of a compressor failure or maintenance activities.

6. Monitoring and Alarms:

Modern screw compressors used in medical air supply systems often feature advanced monitoring capabilities. They can continuously monitor and record key parameters such as pressure, temperature, and system performance. Alarms and alerts can be configured to notify operators or maintenance personnel in case of abnormal conditions or potential issues with the compressor.

7. Compliance with Standards and Regulations:

When using screw compressors for medical air supply, it is essential to comply with relevant standards and regulations. These may include medical device regulations, electrical safety standards, and guidelines specific to medical gas systems. Compliance ensures that the medical air supply system meets the necessary safety and quality requirements.

In summary, screw compressors can be used for medical air supply, providing reliable and efficient compressed air for various medical applications. With their reliability, oil-free operation, adherence to air quality standards, integrated drying and filtration capabilities, and the ability to incorporate redundancy and monitoring features, screw compressors are well-suited for medical air supply systems in healthcare facilities.

How Does a Screw Compressor Work?

A screw compressor operates based on a unique rotary positive displacement principle. Here’s a detailed explanation:

Working Principle:

A screw compressor consists of two helical rotors, typically referred to as male and female rotors, that rotate in opposite directions within a housing. The rotors have specially designed profiles that interlock with each other, creating a series of compression chambers as they rotate. The compression chambers gradually reduce in volume as the rotors rotate, compressing the air or gas trapped inside.

Suction Process:

The suction process begins when the rotors start rotating. As they rotate, the helical lobes or threads on the rotors create expanding spaces between them. The expanding spaces draw in the air or gas from the inlet port, allowing it to enter the compression chamber. The suction process continues as the rotors rotate, and the expanding spaces move the air or gas towards the discharge side of the compressor.

Compression Process:

As the air or gas enters the compression chamber, it gets trapped between the interlocking lobes or threads of the rotors. As the rotors continue to rotate, the trapped air or gas is carried along the length of the rotors. The volume of the compression chamber gradually decreases as the lobes or threads of the rotors intermesh, compressing the air or gas. The compression process is continuous and smooth as the air or gas moves from the suction side to the discharge side of the compressor.

Discharge Process:

Once the air or gas reaches the discharge end of the compression chamber, it is pushed towards the outlet port. The compressed air or gas is then released from the compressor through the outlet port to be used for various applications.

Oil-Injected and Oil-Free Variants:

Screw compressors are available in both oil-injected and oil-free variants. In oil-injected screw compressors, a small amount of lubricating oil is injected into the compression chamber. The oil provides lubrication, cooling, and sealing between the rotors, reducing friction and minimizing wear. The oil-injected variant is commonly used in industrial applications where a small amount of oil in the compressed air is acceptable.

Oil-free screw compressors, on the other hand, are designed to operate without the need for oil lubrication. These compressors use specialized rotor coatings, such as PTFE (polytetrafluoroethylene) or other non-stick materials, to reduce friction and eliminate the need for oil. Oil-free screw compressors are preferred in applications that require oil-free and contaminant-free compressed air, such as in the food and beverage, pharmaceutical, and electronics industries.

In summary, a screw compressor works by utilizing interlocking helical rotors to compress air or gas. The rotating rotors draw in the air or gas during the suction process, and as they rotate, the trapped air or gas is compressed within the compression chamber. The compressed air or gas is then discharged from the compressor. Screw compressors are available in oil-injected and oil-free variants, catering to different application requirements.
