    The 2 stage 3 phase permanent magnet rotary gear screw air compressor of CHINAMFG is powered by 2 independent PM motors and 2 independent inverters, which is intelligently controlled such as keep the airend running at a best level-pressure point by controlling discharge pressure and interstage pressure under the circumstance of different rotary speed and different pressure. The best running speed of air compressor can be automatically calculated while running and then the compression ratio can be balanced by final match, which can keep the compressor in a best running state, thus obtaining the highest efficiency.
  • More effective: high-efficiency permanent magnet motor and no gear drive loss.
    With a motor of a high protection degree of IP54, it is more energy-saving and it can stay effective at low frequency and low speed.
  • More environment-friendly operation with lower noise
    No noise of motor bearings, gear meshing and coupling transmission.
  • More structure-compact
    The volume of PM motor is small and the structure is compact, which can save much space.

    4.Specifications and parameters

     

    5.Principle of energy-saving
     

    • Change the traditional induction motor with high-efficiency technology of permanent magnet rotary screw motor, thus reducing the consumption in transmission.
    • Powered by 2 independent PM motors and 2 independent inverters, the compressor is intelligently controlled such as keep the airend running at a best level-pressure point by controlling pressure of air flow and interstage pressure under the circumstance of different rotary speed and different pressure. The best running speed of compressor can be automatically calculated while running and then the compression ratio can be balanced by final match, which can keep the compressor in a best running state, thus obtaining the highest efficiency.
    • Because the gear ratio is fixed, point efficiency is emphasized in this case. That is to say, only with fixed rotary speed and rated pressure did it have the best specific power. When running in a state of variable speed and variable frequency, considering the fixed speed of gear, interstage pressure will not reach the best one. Rotational speed declining while energy consumption not declining at the same time, it is not suitable for running in variable speed and variable frequency state.

    Can air compressors be used for gas compression and storage?

    Yes, air compressors can be used for gas compression and storage. While air compressors are commonly used to compress and store air, they can also be utilized for compressing and storing other gases, depending on the specific application requirements. Here’s how air compressors can be used for gas compression and storage:

    Gas Compression:

    Air compressors can compress various gases by utilizing the same principles applied to compressing air. The compressor takes in the gas at a certain pressure, and through the compression process, it increases the pressure and reduces the volume of the gas. This compressed gas can then be used for different purposes, such as in industrial processes, gas pipelines, or storage systems.

    Gas Storage:

    Air compressors can also be used for gas storage by compressing the gas into storage vessels or tanks. The compressed gas is stored at high pressure within these vessels until it is needed for use. Gas storage is commonly employed in industries where a continuous and reliable supply of gas is required, such as in natural gas storage facilities or for storing compressed natural gas (CNG) used as a fuel for vehicles.

    Gas Types:

    While air compressors are primarily designed for compressing air, they can be adapted to handle various gases, including but not limited to:

    • Nitrogen
    • Oxygen
    • Hydrogen
    • Carbon dioxide
    • Natural gas
    • Refrigerant gases

    It’s important to note that when using air compressors for gas compression and storage, certain considerations must be taken into account. These include compatibility of the compressor materials with the specific gas being compressed, ensuring proper sealing to prevent gas leaks, and adhering to safety regulations and guidelines for handling and storing compressed gases.

    How do you maintain proper air quality in compressed air systems?

    Maintaining proper air quality in compressed air systems is essential to ensure the reliability and performance of pneumatic equipment and the safety of downstream processes. Here are some key steps to maintain air quality:

    1. Air Filtration:

    Install appropriate air filters in the compressed air system to remove contaminants such as dust, dirt, oil, and water. Filters are typically placed at various points in the system, including the compressor intake, aftercoolers, and before point-of-use applications. Regularly inspect and replace filters to ensure their effectiveness.

    2. Moisture Control:

    Excessive moisture in compressed air can cause corrosion, equipment malfunction, and compromised product quality. Use moisture separators or dryers to remove moisture from the compressed air. Refrigerated dryers, desiccant dryers, or membrane dryers are commonly employed to achieve the desired level of dryness.

    3. Oil Removal:

    If the compressed air system utilizes oil-lubricated compressors, it is essential to incorporate proper oil removal mechanisms. This can include coalescing filters or adsorption filters to remove oil aerosols and vapors from the air. Oil-free compressors eliminate the need for oil removal.

    4. Regular Maintenance:

    Perform routine maintenance on the compressed air system, including inspections, cleaning, and servicing of equipment. This helps identify and address any potential issues that may affect air quality, such as leaks, clogged filters, or malfunctioning dryers.

    5. Air Receiver Tank Maintenance:

    Regularly drain and clean the air receiver tank to remove accumulated contaminants, including water and debris. Proper maintenance of the tank helps prevent contamination from being introduced into the compressed air system.

    6. Air Quality Testing:

    Periodically test the quality of the compressed air using appropriate instruments and methods. This can include measuring particle concentration, oil content, dew point, and microbial contamination. Air quality testing provides valuable information about the effectiveness of the filtration and drying processes and helps ensure compliance with industry standards.

    7. Education and Training:

    Educate personnel working with compressed air systems about the importance of air quality and the proper procedures for maintaining it. Provide training on the use and maintenance of filtration and drying equipment, as well as awareness of potential contaminants and their impact on downstream processes.

    8. Documentation and Record-Keeping:

    What is the role of air compressor tanks?

    Air compressor tanks, also known as receiver tanks or air receivers, play a crucial role in the operation of air compressor systems. They serve several important functions:

    1. Storage and Pressure Regulation: The primary role of an air compressor tank is to store compressed air. As the compressor pumps air into the tank, it accumulates and pressurizes the air. The tank acts as a reservoir, allowing the compressor to operate intermittently while providing a steady supply of compressed air during periods of high demand. It helps regulate and stabilize the pressure in the system, reducing pressure fluctuations and ensuring a consistent supply of air.

    2. Condensation and Moisture Separation: Compressed air contains moisture, which can condense as the air cools down inside the tank. Air compressor tanks are equipped with moisture separators or drain valves to collect and remove this condensed moisture. The tank provides a space for the moisture to settle, allowing it to be drained out periodically. This helps prevent moisture-related issues such as corrosion, contamination, and damage to downstream equipment.

    3. Heat Dissipation: During compression, air temperature increases. The air compressor tank provides a larger surface area for the compressed air to cool down and dissipate heat. This helps prevent overheating of the compressor and ensures efficient operation.

    4. Pressure Surge Mitigation: Air compressor tanks act as buffers to absorb pressure surges or pulsations that may occur during compressor operation. These surges can be caused by variations in demand, sudden changes in airflow, or the cyclic nature of reciprocating compressors. The tank absorbs these pressure fluctuations, reducing stress on the compressor and other components, and providing a more stable and consistent supply of compressed air.

    5. Energy Efficiency: Air compressor tanks contribute to energy efficiency by reducing the need for the compressor to run continuously. The compressor can fill the tank during periods of low demand and then shut off when the desired pressure is reached. This allows the compressor to operate in shorter cycles, reducing energy consumption and minimizing wear and tear on the compressor motor.

    6. Emergency Air Supply: In the event of a power outage or compressor failure, the stored compressed air in the tank can serve as an emergency air supply. This can provide temporary air for critical operations, allowing time for maintenance or repairs to be carried out without disrupting the overall workflow.

    Overall, air compressor tanks provide storage, pressure regulation, moisture separation, heat dissipation, pressure surge mitigation, energy efficiency, and emergency backup capabilities. They are vital components that enhance the performance, reliability, and longevity of air compressor systems in various industrial, commercial, and personal applications.

    Are there differences between single-stage and two-stage air compressors?

    Yes, there are differences between single-stage and two-stage air compressors. Here’s an in-depth explanation of their distinctions:

    Compression Stages:

    The primary difference between single-stage and two-stage air compressors lies in the number of compression stages they have. A single-stage compressor has only one compression stage, while a two-stage compressor has two sequential compression stages.

    Compression Process:

    In a single-stage compressor, the entire compression process occurs in a single cylinder. The air is drawn into the cylinder, compressed in a single stroke, and then discharged. On the other hand, a two-stage compressor utilizes two cylinders or chambers. In the first stage, air is compressed to an intermediate pressure in the first cylinder. Then, the partially compressed air is sent to the second cylinder where it undergoes further compression to reach the desired final pressure.

    Pressure Output:

    The number of compression stages directly affects the pressure output of the air compressor. Single-stage compressors typically provide lower maximum pressure levels compared to two-stage compressors. Single-stage compressors are suitable for applications that require moderate to low air pressure, while two-stage compressors are capable of delivering higher pressures, making them suitable for demanding applications that require greater air pressure.

    Efficiency:

    Two-stage compressors generally offer higher efficiency compared to single-stage compressors. The two-stage compression process allows for better heat dissipation between stages, reducing the chances of overheating and improving overall efficiency. Additionally, the two-stage design allows the compressor to achieve higher compression ratios while minimizing the work done by each stage, resulting in improved energy efficiency.

    Intercooling:

    Intercooling is a feature specific to two-stage compressors. Intercoolers are heat exchangers placed between the first and second compression stages. They cool down the partially compressed air before it enters the second stage, reducing the temperature and improving compression efficiency. The intercooling process helps to minimize heat buildup and reduces the potential for moisture condensation within the compressor system.

    Applications:

    The choice between a single-stage and two-stage compressor depends on the intended application. Single-stage compressors are commonly used for light-duty applications such as powering pneumatic tools, small-scale workshops, and DIY projects. Two-stage compressors are more suitable for heavy-duty applications that require higher pressures, such as industrial manufacturing, automotive service, and large-scale construction.

    It is important to consider the specific requirements of the application, including required pressure levels, duty cycle, and anticipated air demand, when selecting between a single-stage and two-stage air compressor.

    In summary, the main differences between single-stage and two-stage air compressors lie in the number of compression stages, pressure output, efficiency, intercooling capability, and application suitability.
