Working principle of scroll compressor
The core components of the scroll compressor are two scrolls: a fixed fixed scroll and a moving scroll that rotates under the drive of the eccentric shaft. The two scrolls are shaped like a pair of meshing spirals, and their meshing forms a series of gradually decreasing compression chambers.
Gas suction: The gas enters the outer edge of the fixed scroll through the air inlet.
Gas compression: As the moving scroll rotates under the drive of the eccentric shaft, the meshing between the moving scroll and the fixed scroll forms a series of gradually decreasing compression chambers. The gas is gradually compressed in these compression chambers, the volume gradually decreases, and the pressure gradually increases.
Gas discharge: When the compression chamber moves to the center of the fixed scroll, the gas is compressed to the highest pressure and discharged through the exhaust hole in the center of the fixed scroll.
The role of the fixed and moving disks in the compression process
In the scroll compressor, the fixed and moving disks are the core components, and they work together to complete the gas compression task. The static disk is fixed, while the dynamic disk rotates around the center of the static disk under the drive of the eccentric shaft. The meshing of the static disk and the dynamic disk forms a series of gradually decreasing compression chambers. As the dynamic disk rotates, the gas in these compression chambers is gradually compressed and finally discharged through the exhaust hole in the center of the static disk. This design enables the gas to be evenly stressed during the compression process, improving the compression efficiency and stability.
Function of the eccentric shaft in the scroll compressor
The eccentric shaft is a key component that drives the dynamic disk to rotate. It converts the rotational motion of the motor into the eccentric motion of the dynamic disk through the connection with the dynamic disk. This motion enables the dynamic disk to form a series of gradually decreasing compression chambers with the static disk during the rotation process to achieve gas compression. The design and manufacturing accuracy of the eccentric shaft directly affects the performance and life of the scroll compressor. The scroll compressor manufacturer pays great attention to its quality and reliability when selecting and manufacturing the eccentric shaft.
The role of the anti-rotation mechanism in the rotation process of the dynamic disk
The anti-rotation mechanism is an important component to ensure the stable operation of the dynamic disk during the rotation process. It limits the rotational freedom of the moving disk so that it can only perform a predetermined eccentric movement under the drive of the eccentric shaft. This can prevent the moving disk from shaking or deflecting during the rotation process, ensuring the stability and efficiency of the compression process. The design and performance of the anti-rotation mechanism have an important impact on the overall performance of the scroll compressor. The Refrigeration Compressors Manufacturer will conduct strict quality control when designing and manufacturing the anti-rotation mechanism.
Why does the scroll compressor use the structure of the moving scroll and the fixed scroll?
The scroll compressor uses the structure of the moving scroll and the fixed scroll mainly to achieve efficient and stable gas compression. The meshing of the moving scroll and the fixed scroll forms a series of gradually decreasing compression chambers. This design allows the gas to be evenly stressed during the compression process, improving the compression efficiency and stability. This structure has the advantages of small size, light weight, and low noise, allowing the scroll compressor to perform well in various application scenarios. Many compressor suppliers and scroll compressor manufacturers choose to use this structure to manufacture scroll compressors.
