Product Description

ZheJiang CHINAMFG Pharmaceutical Rotary Single Screw Oil-free air compressors for clean air

Product Description

1. Overview

Oil-free screw air compressors are widely used in industries that require high-quality air sources such as medicine, food, electronics, chemicals, packaging, etc. 100% pure compressed air is a necessary measure to ensure process and product quality, and high-end products that can be produced risk-free and safely

The lubrication system in oil-free screw air compressors is a separated oil supply circulation unit, the compression chamber and the bearing are tightly separated by a high-performance mechanical seal assembly. The lubricating oil can only flow in the enclosed area and cannot enter the compression chamber. The compressed room is pure air that is not contained. After a little treatment of water and dust removal, 100% pure compressed air can be obtained

The oil-free screw air compressor compresses the air through a two-stage screw rotor, and removes the water in the compressed air through a water-gas separator. At the same time, because there is no spread oil cooling, a pre-cooler, intercooler, and after-cooler are generally configured to cool the compressed air to reach the required exhaust temperature. A shaft seal with excellent performance is used on the shaft of the rotor to prevent lubricating oil from leaking into the compressed air to achieve true oil-free.

What is the role of air compressors in power generation?

Air compressors play a significant role in power generation, supporting various operations and equipment within the industry. Here are some key roles of air compressors in power generation:

1. Combustion Air Supply:

Air compressors are used to supply compressed air for the combustion process in power generation. In fossil fuel power plants, such as coal-fired or natural gas power plants, compressed air is required to deliver a steady flow of air to the burners. The compressed air helps in the efficient combustion of fuel, enhancing the overall performance and energy output of the power plant.

2. Instrumentation and Control:

Air compressors are utilized for instrumentation and control systems in power generation facilities. Compressed air is used to operate pneumatic control valves, actuators, and other pneumatic devices that regulate the flow of steam, water, and gases within the power plant. The reliable and precise control provided by compressed air ensures efficient and safe operation of various processes and equipment.

3. Cooling and Ventilation:

In power generation, air compressors are involved in cooling and ventilation applications. Compressed air is used to drive air-operated cooling fans and blowers, providing adequate airflow for cooling critical components such as generators, transformers, and power electronics. The compressed air also assists in maintaining proper ventilation in control rooms, substations, and other enclosed spaces, helping to dissipate heat and ensure a comfortable working environment.

4. Cleaning and Maintenance:

Air compressors are employed for cleaning and maintenance tasks in power generation facilities. Compressed air is utilized to blow away dust, dirt, and debris from equipment, machinery, and electrical panels. It helps in maintaining the cleanliness and optimal performance of various components, reducing the risk of equipment failure and improving overall reliability.

5. Pneumatic Tools and Equipment:

In power generation plants, air compressors provide the necessary compressed air for operating pneumatic tools and equipment. These tools include impact wrenches, pneumatic drills, grinders, and sandblasting equipment, which are utilized for installation, maintenance, and repair tasks. The high-pressure air generated by compressors enables efficient and reliable operation of these tools, enhancing productivity and reducing manual effort.

6. Nitrogen Generation:

Sometimes, air compressors are used in power generation for nitrogen generation. Compressed air is passed through a nitrogen generator system, which separates nitrogen from other components of air, producing a high-purity nitrogen gas stream. Nitrogen is commonly used in power plant applications, such as purging systems, blanketing in transformers, and generator cooling, due to its inert properties and low moisture content.

7. Start-up and Emergency Systems:

Air compressors are an integral part of start-up and emergency systems in power generation. Compressed air is utilized to power pneumatic starters for gas turbines, providing the initial rotation needed to start the turbine. In emergency situations, compressed air is also used to actuate emergency shutdown valves, safety systems, and fire suppression equipment, ensuring the safe operation and protection of the power plant.

Overall, air compressors contribute to the efficient and reliable operation of power generation facilities, supporting combustion processes, control systems, cooling, cleaning, and various other applications critical to the power generation industry.

What is the impact of altitude on air compressor performance?

The altitude at which an air compressor operates can have a significant impact on its performance. Here are the key factors affected by altitude:

1. Decreased Air Density:

As altitude increases, the air density decreases. This means there is less oxygen available per unit volume of air. Since air compressors rely on the intake of atmospheric air for compression, the reduced air density at higher altitudes can lead to a decrease in compressor performance.

2. Reduced Airflow:

The decrease in air density at higher altitudes results in reduced airflow. This can affect the cooling capacity of the compressor, as lower airflow hampers the dissipation of heat generated during compression. Inadequate cooling can lead to increased operating temperatures and potential overheating of the compressor.

3. Decreased Power Output:

Lower air density at higher altitudes also affects the power output of the compressor. The reduced oxygen content in the air can result in incomplete combustion, leading to decreased power generation. As a result, the compressor may deliver lower airflow and pressure than its rated capacity.

4. Extended Compression Cycle:

At higher altitudes, the air compressor needs to work harder to compress the thinner air. This can lead to an extended compression cycle, as the compressor may require more time to reach the desired pressure levels. The longer compression cycle can affect the overall efficiency and productivity of the compressor.

5. Pressure Adjustments:

When operating an air compressor at higher altitudes, it may be necessary to adjust the pressure settings. As the ambient air pressure decreases with altitude, the compressor’s pressure gauge may need to be recalibrated to maintain the desired pressure output. Failing to make these adjustments can result in underinflated tires, improper tool performance, or other issues.

6. Compressor Design:

Some air compressors are specifically designed to handle higher altitudes. These models may incorporate features such as larger intake filters, more robust cooling systems, and adjusted compression ratios to compensate for the reduced air density and maintain optimal performance.

7. Maintenance Considerations:

Operating an air compressor at higher altitudes may require additional maintenance and monitoring. It is important to regularly check and clean the intake filters to ensure proper airflow. Monitoring the compressor’s operating temperature and making any necessary adjustments or repairs is also crucial to prevent overheating and maintain efficient performance.

When using an air compressor at higher altitudes, it is advisable to consult the manufacturer’s guidelines and recommendations specific to altitude operations. Following these guidelines and considering the impact of altitude on air compressor performance will help ensure safe and efficient operation.

How is air pressure measured in air compressors?

Air pressure in air compressors is typically measured using one of two common units: pounds per square inch (PSI) or bar. Here’s a brief explanation of how air pressure is measured in air compressors:

1. Pounds per Square Inch (PSI): PSI is the most widely used unit of pressure measurement in air compressors, especially in North America. It represents the force exerted by one pound of force over an area of one square inch. Air pressure gauges on air compressors often display pressure readings in PSI, allowing users to monitor and adjust the pressure accordingly.

2. Bar: Bar is another unit of pressure commonly used in air compressors, particularly in Europe and many other parts of the world. It is a metric unit of pressure equal to 100,000 pascals (Pa). Air compressors may have pressure gauges that display readings in bar, providing an alternative measurement option for users in those regions.

To measure air pressure in an air compressor, a pressure gauge is typically installed on the compressor’s outlet or receiver tank. The gauge is designed to measure the force exerted by the compressed air and display the reading in the specified unit, such as PSI or bar.

It’s important to note that the air pressure indicated on the gauge represents the pressure at a specific point in the air compressor system, typically at the outlet or tank. The actual pressure experienced at the point of use may vary due to factors such as pressure drop in the air lines or restrictions caused by fittings and tools.

When using an air compressor, it is essential to set the pressure to the appropriate level required for the specific application. Different tools and equipment have different pressure requirements, and exceeding the recommended pressure can lead to damage or unsafe operation. Most air compressors allow users to adjust the pressure output using a pressure regulator or similar control mechanism.

Regular monitoring of the air pressure in an air compressor is crucial to ensure optimal performance, efficiency, and safe operation. By understanding the units of measurement and using pressure gauges appropriately, users can maintain the desired air pressure levels in their air compressor systems.
