Working principle of scroll air compressor


· Air is drawn in through an inlet located on the outer surface of the stationary vortex disc.

The air enclosed in the compression chamber is compressed towards the center of the chamber reducing the load due to the rotational movement.

· The compression space in the center is minimal, and the highly compressed air is pushed to the outside through the central vent.

Movements 1 - 3 (inhalation > compression > exhalation) are repeated.

 

Reliable and stable


Vortex discs of scroll compressors work at high temperatures due to lack of lubricating oil during operation. The developed tooth profile technology has well solved the problem of vortex disk thermal deformation at high temperature and almost ensured the reliability of the scroll compressor.
Bearings are surface treated with high reliability.
Low vibration and low noise
Optimal scroll cabinet design with low noise close to the library environment. (3.7KW model, noise value only 47dB[A])

 

Easy maintenance


The medium-term maintenance cycle extends to five years or 12500 hours from the original four years or 10000 hours.
The maintenance cycle for 1.0MPa pressure compressors is still four years or 10,000 hours.
By adding the oiling port, it is possible to refill the grease without removing the scroll disc of the scroll compressor. Simplify the maintenance process.
Energy saving in complex control of multiple compressors
Based on P mode control, multi-compressor composite control is added, allowing switching between the two combinations.
Under the multi-compressor complex control mode, it automatically controls the number of compressors running according to the intake air consumption, simplifying compressor operation while the required air pressure is guaranteed.

Control mode

Similar to the pressure switch mode, when the maximum pressure is reached, the compressor stops running. When the resume pressure is reached, the compressor will restart.

 

Multi-compressor complex control

The compressor exhaust pressure is automatically controlled around the required pressure (control pressure). Avoid unnecessary power consumption to achieve maximum pressure, thus saving energy.

 

Rear function

Several scroll compressors are linked together if one of the units fails, the rest can still guarantee a continuous air supply.

 

  • Emissions will be smaller than standard specifications.
  • Optimal cabinet design
  • Save installation space.
  • Low vibration and low noise.

Product Description


The stationary vortex disc and the movable vortex disc of the oil-free scroll compressor move in a plane with a small radius according to a particular phase. The vortex disc moves and the mesh vortex is static to form several closed crescent-shaped compression chambers. The air inhaled into the working chamber is gradually compressed by the crescent-shaped compression chamber and then discharged from the outlet at the center of the stationary vortex disc. Oil-free scroll compressor produces oil-free compressed air which is widely used in the fields of food, medicine, electronics, printing, chemical industry, precision paint spraying and other fields.
