PM VSD Screw Air Compressor

The Screw Air Compressor is a widely - used and reliable device in the air - compression industry. It features a pair of intermeshing helical rotors, commonly known as screws. As these rotors rotate, air is trapped in the grooves between the threads and gradually compressed as it moves along the length of the screws.
This type of compressor offers several key advantages. It has a high - volume air - delivery capacity, making it suitable for various industrial applications that require a continuous and large - volume supply of compressed air. Its operation is relatively stable, with less pulsation in the air output compared to some other compressor types. Additionally, screw air compressors are known for their durability and long - service life. They can withstand high - pressure operations and are often used in industries such as manufacturing, construction, and mining. With continuous technological advancements, modern screw air compressors also come with energy - saving features, contributing to cost - effective and sustainable operation.

  1.  Two-stage Compression Design:The compressor is equipped with a two-stage compression system. In this design, air is compressed in two successive stages, each utilizing an independent compression unit. This approach enables a lower compression ratio in each stage, which reduces leakage and enhances volumetric efficiency. For example, compared to single-stage compression, it can improve the air delivery volume by more than 15% under identical power conditions.


  2. The motor employed is a high-efficiency permanent magnet synchronous motor, which offers the benefits of moderate airflow and a broad speed regulation range. By precisely controlling the motor speed using variable frequency technology, the compressor can adjust the air output to match actual air demand, thereby achieving energy savings.photobank

1. Energy Efficiency: The integration of two-stage compression and permanent magnet variable frequency technology enhances the compressor's energy efficiency by approximately 30% compared to conventional air compressors. This system eliminates idling and reduces excessive pressure waste. Additionally, the efficiency of the permanent magnet motor is approximately 5% to 8% greater than that of standard motors, leading to substantial energy savings.


2. High Reliability: The rotor features a new energy-saving and efficient design, and the primary components are meticulously selected to ensure maximum durability and an extended service life. The compressor is equipped with an independent lubrication system for the main engine gear, which guarantees the reliable operation of the machine.


3. Low Noise and Vibration: The incorporation of an advanced noise-reduction design results in quieter compressor operation, with noise levels ranging from 64 ± 2 dB(A) to 86 ± 2 dB(A), depending on the model.


4. Intelligent Controller: The compressor is equipped with an advanced microcomputer control system that supports switching between Chinese and English. This system facilitates intelligent monitoring and management of the usage time for air filters, oil filters, oil separators, and lubricating oil. Furthermore, it features an ooptional remote monitoring function, enabling users to check the operational status of the device at any time through the IoT system.


5. The compressor is equipped with a "simple management" mode that features a fully touch-screen interface, allowing for convenient and rapid parameter modifications. Users can easily configure intelligent timed on/off settings or timed pressure adjustments to enable smart network control.
