2. Product introduction
 

L series permanent magnet rotary screw air compressor 3-5 bar are specially developed for industries that need low air pressure operation such as textile, cement, glass and food. With a low pressure range from 3 bar to 5 bar, the power range of L series is from 37kw to 132kw and the air delivery of that is from 8.34m3/min to 85.82m3/min.
The main engine is a low pressure design developed by CHINAMFG instead of an ordinary one. When a low pressure compressor is equipped with a common main engine, the air will be largely compressed first and then released, which will lead to unnecessary high energy consumption. However, a professional low pressure main engine will save 10%-20% energy compared with common compressors.
The industrial rotary screw air compressors are equipped with motors with a protection degree of IP54 and inovance frequency inverter, which turn out to be effective, energy-saving, structure-compact and lower noise.

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.Specifications and parameters

     
     

    Examples of comparison of low pressure compressor’s and common compressor’s working conditions in the low pressure state:
    When users’ actual need for pressure is 0.4MPa, however, if a 0.8MPa 1 was used in this case, the compressor will compress the air to 0.8MPa first and then reduce it to 0.4MPa by pressure-reducing valve or other ways. That is to say, the 0.8MPa energy consumption is taken by users.

    For example, the actual air delivery of 45kw/0.4MPa low pressure compressor of CHINAMFG is 10.84 m3min and the actual work is 44.8KW and the specific power is 4.13kw/m3. However, the specific power of common 45kw/0.8MPa compressor is 8.1kw/m3, according to the 2 level energy efficiency calculation. In this case, professional 0.4MPa low pressure compressor can save nearly 49% energy compared with common ones.

    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.

    What is the impact of humidity on compressed air quality?

    Humidity can have a significant impact on the quality of compressed air. Compressed air systems often draw in ambient air, which contains moisture in the form of water vapor. When this air is compressed, the moisture becomes concentrated, leading to potential issues in the compressed air. Here’s an overview of the impact of humidity on compressed air quality:

    1. Corrosion:

    High humidity in compressed air can contribute to corrosion within the compressed air system. The moisture in the air can react with metal surfaces, leading to rust and corrosion in pipes, tanks, valves, and other components. Corrosion not only weakens the structural integrity of the system but also introduces contaminants into the compressed air, compromising its quality and potentially damaging downstream equipment.

    2. Contaminant Carryover:

    Humidity in compressed air can cause carryover of contaminants. Water droplets formed due to condensation can carry particulates, oil, and other impurities present in the air. These contaminants can then be transported along with the compressed air, leading to fouling of filters, clogging of pipelines, and potential damage to pneumatic tools, machinery, and processes.

    3. Decreased Efficiency of Pneumatic Systems:

    Excessive moisture in compressed air can reduce the efficiency of pneumatic systems. Water droplets can obstruct or block the flow of air, leading to decreased performance of pneumatic tools and equipment. Moisture can also cause problems in control valves, actuators, and other pneumatic devices, affecting their responsiveness and accuracy.

    4. Product Contamination:

    In industries where compressed air comes into direct contact with products or processes, high humidity can result in product contamination.
