How is the compression process of the PFM compressor

How is the compression process of the PFM compressor One of the PFM compressors is a scroll compressor. How is its compression process completed? We can find the answer in this article.

First of all, we must know that there are two scrolls in the upper part of the PFM compressor, a moving scroll and a static scroll. The center of the movable scroll makes a circular motion around the center of the fixed scroll under the drive of the main shaft. This movement produces compression between the two vortices, and the low-pressure gas enters the suction chamber. With the movement of the movable scroll, compression is a continuous process In the second circular motion, a part of the gas is compressed, another part of the gas is entering the scroll, and a part of the gas is being discharged. The volume of the cavity gradually decreases. When this cavity reaches the center, that is, the exhaust port, the pressure reaches the maximum, which passes through three complete circular movements. A check valve is designed on the exhaust port of the fixed scroll to prevent the compressor from reversing when the telephone source is cut off. Finally, the exhaust gas leaves the compressor and enters the exhaust pipe. 　　The two scrolls are located above the motor, and the suction air enters the compressor through the suction interface. The gas flows around the motor and enters the motor through the bottom opening of the motor. The compression of the Biomax compressor is accomplished by these two scrolls. 　　Baifuma scroll compressor, lubricating oil is separated from the suction and dripped into the oil pool. All gases pass through the motor to ensure that the motor is completely cooled under any circumstances. Gas leaves the motor and enters the scroll. 　　 Therefore, the compression process of the Biomax compressor is completed in this way! All compression processes rely on these two scrolls. Without them, this compression process cannot be completed.
