Reciprocating compressor is a common type of compressor, widely used in refrigeration, air conditioning, industrial gas transportation and other fields. This article will introduce the working principle of reciprocating compressors and their applications.
First, the working principle of reciprocating compressor reciprocating compressor is through the piston in the cylinder to do reciprocating motion, the gas compression and discharge of a compressor. Its working principle mainly includes suction, compression, exhaust three processes.
1. suction process: when the piston downward movement, the volume inside the cylinder increases, the pressure inside the cylinder decreases, so that the external gas through the suction valve into the cylinder. The suction valve closes when the piston moves upward, preventing the gas from flowing backward.
2. Compression process: When the piston moves upward, the volume inside the cylinder decreases, the gas is compressed and the pressure gradually increases. When the gas pressure reaches the set value, the compression process ends.
3. Exhaust process: When the piston moves downward again, the volume inside the cylinder increases and the pressure decreases, so that the compressed gas is discharged through the exhaust valve. The exhaust valve is closed when the piston moves upward to prevent the gas from flowing backward.
Second, the application of reciprocating compressor reciprocating compressor because of its simple structure, high reliability, compression ratio and other characteristics, is widely used in various fields.
1. Refrigeration and air conditioning: reciprocating compressor is a common type of compressor in refrigeration and air conditioning systems. It can inhale the low-temperature and low-pressure refrigerant, increase its temperature and pressure through compression, and then transfer the high-temperature and high-pressure refrigerant to the condenser for heat dissipation, so as to realize the refrigeration effect.
2. Industrial gas transportation: reciprocating compressors are used in the industrial field to transport gases, such as compressed air, nitrogen, oxygen and so on. Through the working principle of reciprocating compressor, the gas will be compressed to a certain pressure, and then transported through the pipeline to the place where it is needed.
3. Automobile engines: Reciprocating compressors in automobile engines are known as piston compressors and are used to compress air to provide the oxygen needed for engine combustion. Piston compressors work on a similar principle to reciprocating compressors, compressing air by the reciprocating motion of a piston.
Reciprocating compressors are a common and important type of compressor with a simple and clear working principle and a wide range of applications. Whether it is refrigeration and air conditioning, industrial gas transportation or automobile engines, reciprocating compressors play an important role. With the continuous progress of science and technology, the performance and efficiency of reciprocating compressors are also constantly improving, for the development of various fields to make a contribution.
