High Pressure Water Lubricated Oil Free Air Compressor Detailed Drawing

The working principle and the characteristics of a single screw compressor:

  • Simple construction Low-vibration
    A single-screw compressor is comprised of a single screw and two wheels that are located within the screw. Axial and radial loads cancel each other and result in a virtually non-load. It is the most advanced design structure for a single screw compressor.
  • High-efficiency
    The first reason is it is that the screw compressors don’t have clearance. Additionally, water used to lubricate air may help to seal the gap in the chamber of compression which allows high-efficiency operation with a lower rate. The third reason is that water cooling the compressor will keep the compressor operating at an ideal temperature for compression.
  • Save energy
    In the event that the actual usage of air is not greater than the flow rate that is recommended and the compressor is running at a lower speed, it will draw more power, however, there is no output of air while taking off. With an inverter, the compressor can adjust its speed in accordance with the pressure of air that is determined, resulting in the reduction of energy consumption.
  • Less noise
    The motor and the screws are directly connected, without rotation gears which could create noise within the motor. Additionally, the use of sound-absorbing materials is also made in the shell of the equipment to minimize noise.
  • Stable air delivery
    The valve controls the pressure sensor. The digital controller adjusts the speed of the motor’s rotation through an inverter. This is how it regulates the flow of air pressure to ensure a constant flow of air.
  • Monitorable
    Intelligent monitoring is utilized to prevent injuries. The emergency alarm is displayed on computers and messages of a short length are also reported to supervisors. These are essential to prevent production-related accidents.
