Compressor working principle

Compressor working principle Compressor working principle 　　 Centrifugal compressor The centrifugal compressor is a working wheel with blades rotating on the shaft of the compressor. The gas entering the working wheel is carried by the blades to increase the kinetic energy (speed) and static pressure head (pressure), and then the working wheel enters the diffuser Inside, the velocity of the gas in the diffuser is converted to pressure to further increase the pressure. The compressed gas then enters the next stage impeller through the bend and the recirculator to be further compressed to the required pressure. For example, a shaft is driven by a prime mover (motor). There are 4 impellers on the shaft, just like a shaft with 4 electric fans. The wind of one electric fan is transmitted to the second electric fan. It was passed to another electric fan, and in the end you felt that the force of the wind was quite the same. In this way, the centrifugal compressor increases the pressure of the gas through the impeller. Piston compressor When the crankshaft of the piston compressor rotates, the piston will reciprocate through the transmission of the connecting rod, and the working volume composed of the inner wall of the cylinder, the cylinder head and the top surface of the piston will periodically change. When the piston of the piston compressor starts to move from the cylinder head, the working volume in the cylinder gradually increases. At this time, the gas follows the intake pipe and pushes the intake valve to enter the cylinder until the working volume reaches the maximum , The intake valve is closed; when the piston of the piston compressor moves in the reverse direction, the working volume in the cylinder shrinks and the gas pressure increases. When the pressure in the cylinder reaches and is slightly higher than the exhaust pressure, the exhaust valve opens and the gas exits the cylinder Until the piston moves to the limit position, the exhaust valve closes. When the piston of the piston compressor moves again in the reverse direction, the above process repeats itself. In short, the crankshaft of the piston compressor rotates once, the piston reciprocates once, and the process of intake, compression, and exhaust is realized in the cylinder, that is, a working cycle is completed. Synovial ring compressor 　　 The pump body is filled with an appropriate amount of water as a working fluid. Due to the centrifugal force, the water forms a closed ring of approximately equal thickness that depends on the shape of the pump cavity. The inner surface of the upper part of the water ring is exactly tangent to the impeller hub, and the inner surface of the lower part of the water ring is just in contact with the tip of the blade (in fact, the blade has a certain insertion depth in the water ring). At this time, a crescent-shaped space is formed between the impeller hub and the water ring, and this space is divided into several small cavities with equal number of blades by the impeller. If the starting point of the upper part of the impeller is 0°, the volume of the small cavity will increase from small to 180° before the impeller rotates, and it will communicate with the suction port on the end surface. At this time, the gas is drawn in. When the suction is finished, the small cavity It is isolated from the suction port; when the impeller continues to rotate, the small cavity changes from large to small, causing the gas to be compressed; when the small cavity communicates with the exhaust port, the gas is discharged from the pump. Rolling piston compressor 　　 Rolling piston compressor, a driven fluid machinery that raises low-pressure gas to high pressure. It is the heart of the refrigeration system. It sucks low-temperature and low-pressure refrigerant gas from the suction pipe, drives the piston to compress it through the operation of the motor, and discharges the high-temperature and high-pressure refrigerant liquid to the exhaust pipe to provide power for the refrigeration cycle to achieve Compression → condensation → expansion → evaporation (heat absorption) refrigeration cycle. A compressor that realizes gas compression by means of a rotary piston eccentrically installed in a cylinder for rolling movement in a cylindrical cylinder and a reciprocating movement of a sliding plate in contact with the rolling piston.
