2. Product introduction

Equipped with an IE3 motor, the direct drive rotary screw air compressor consists of a high-accuracy screw and high-quality casting, with a wide variable range of parameters.

3.Core components

Motor 

  • More stable: no mechanical transmission troubles
    There is no gear shaft in the air compressor and the effective permanent magnet motor and the male rotor are directly connected on 1 shaft without gear drive, which can eliminate pitting of gear or hidden troubles of tooth fracture.
    Without shaft coupling, 2 integrated PM motors directly drive 2 airends of the air compressor, avoiding the hidden troubles of shaft coupling failure.
  • More energy-savings: the airend is always in a smooth running state
    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.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.

    Power Output:

    The horsepower rating of an air compressor indicates its power output or the rate at which it can perform work. Generally, a higher horsepower rating translates to a greater power output, allowing the air compressor to deliver more compressed air per unit of time. This increased power output enables the compressor to operate pneumatic tools and equipment that require higher air pressure or greater airflow.

    Air Pressure:

    The horsepower of an air compressor is directly related to the air pressure it can generate. Air compressors with higher horsepower ratings have the capacity to produce higher air pressures. This is particularly important when operating tools or machinery that require specific air pressure levels to function optimally. For example, heavy-duty pneumatic tools like jackhammers or impact wrenches may require higher air pressure to deliver the necessary force.

    Air Volume:

    In addition to air pressure, the horsepower of an air compressor also affects the air volume or airflow it can provide. Higher horsepower compressors can deliver greater volumes of compressed air, measured in cubic feet per minute (CFM). This increased airflow is beneficial when using pneumatic tools that require a continuous supply of compressed air, such as paint sprayers or sandblasters.

    Duty Cycle:

    The horsepower rating of an air compressor can also influence its duty cycle. The duty cycle refers to the amount of time an air compressor can operate continuously before it needs to rest and cool down. Higher horsepower compressors often have larger and more robust components, allowing them to handle heavier workloads and operate for longer periods without overheating. This is particularly important in demanding applications where continuous and uninterrupted operation is required.

    Size and Portability:

    It’s worth noting that the horsepower rating can also affect the physical size and portability of an air compressor. Higher horsepower compressors tend to be larger and heavier due to the need for more substantial motors and components to generate the increased power output. This can impact the ease of transportation and maneuverability, especially in portable or mobile applications.

    When selecting an air compressor, it is essential to consider the specific requirements of your intended applications. Factors such as desired air pressure, airflow, duty cycle, and portability should be taken into account. It’s important to choose an air compressor with a horsepower rating that aligns with the demands of the tools and equipment you plan to operate, ensuring optimal performance and efficiency.

    Consulting the manufacturer’s specifications and guidelines can provide valuable information on how the horsepower rating of an air compressor corresponds to its capabilities and suitability for different tasks.

    • Air Dryers and Filters: In sandblasting applications, it is crucial to have clean, dry air to prevent moisture and contaminants from affecting the abrasive blasting process and the quality of the surface being treated. Air compressors may be equipped with air dryers and filters to remove moisture, oil, and impurities from the compressed air.

    When using air compressors for painting or sandblasting, it is important to consider factors such as the compressor’s pressure and volume output, the specific requirements of the application, and the type of tools or equipment being used. Consult the manufacturer’s guidelines and recommendations to ensure the air compressor is suitable for the intended painting or sandblasting tasks.

    Proper safety measures, such as wearing protective gear and following established protocols, should always be followed when working with air compressors for painting and sandblasting applications.

    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.

    What is the difference between a piston and rotary screw compressor?

    Piston compressors and rotary screw compressors are two common types of air compressors with distinct differences in their design and operation. Here’s a detailed explanation of the differences between these two compressor types:

    1. Operating Principle:

    • Piston Compressors: Piston compressors, also known as reciprocating compressors, use one or more pistons driven by a crankshaft to compress air. The piston moves up and down within a cylinder, creating a vacuum during the intake stroke and compressing the air during the compression stroke.
    • Rotary Screw Compressors: Rotary screw compressors utilize two intermeshing screws (rotors) to compress air. As the male and female screws rotate, the air is trapped between them and gradually compressed as it moves along the screw threads.

    2. Compression Method:

    • Piston Compressors: Piston compressors achieve compression through a positive displacement process. The air is drawn into the cylinder and compressed as the piston moves back and forth. The compression is intermittent, occurring in discrete cycles.
    • Rotary Screw Compressors: Rotary screw compressors also employ a positive displacement method. The compression is continuous as the rotating screws create a continuous flow of air and compress it gradually as it moves along the screw threads.

    3. Efficiency:

    • Piston Compressors: Piston compressors are known for their high efficiency at lower flow rates and higher pressures. They are well-suited for applications that require intermittent or variable air demand.
    • Rotary Screw Compressors: Rotary screw compressors are highly efficient for continuous operation and are designed to handle higher flow rates. They are often used in applications with a constant or steady air demand.

    4. Noise Level:

    • Piston Compressors: Piston compressors tend to generate more noise during operation due to the reciprocating motion of the pistons and valves.
    • Rotary Screw Compressors: Rotary screw compressors are generally quieter in operation compared to piston compressors. The smooth rotation of the screws contributes to reduced noise levels.

    5. Maintenance:

    • Piston Compressors: Piston compressors typically require more frequent maintenance due to the higher number of moving parts, such as pistons, valves, and rings.
    • Rotary Screw Compressors: Rotary screw compressors have fewer moving parts, resulting in lower maintenance requirements. They often have longer service intervals and can operate continuously for extended periods without significant maintenance.

    6. Size and Portability:

    • Piston Compressors: Piston compressors are available in both smaller portable models and larger stationary units. Portable piston compressors are commonly used in construction, automotive, and DIY applications.
    • Rotary Screw Compressors: Rotary screw compressors are typically larger and more suitable for stationary installations in industrial and commercial settings. They are less commonly used in portable applications.

    These are some of the key differences between piston compressors and rotary screw compressors. The choice between the two depends on factors such as required flow rate, pressure, duty cycle, efficiency, noise level, maintenance needs, and specific application requirements.
