How does a double acting reciprocating compressor work?

The double acting compressor compresses the air on both the up-stroke and the down-stroke of the piston, doubling the capacity of a given cylinder size. This “double” compression cycle is what makes this type of air compressor very efficient. For every rotation of the electric motor, the air is being compressed twice.

What is double acting compressor?

Double acting compressor cylinders compress gas on both movements of the piston. When the piston is moving toward the head of the cylinder it is compressing gas as well as putting it into the process. At the same time the piston is on the suction stroke of the crankcase half of the cylinder.

How does a reciprocating compressor work?

Reciprocating compressors use cylinders with pistons inside them. Each cylinder has a closed end next to the cylinder head and is finished at the other end with a movable piston. The piston then reverses its motion, fulfilling the “reciprocating” part of the name, and begins compressing the air in the process.

What is an advantage of double acting reciprocating compressors?

Advantages: It produces cheap electricity from compressed air as compared to a single-acting compressor. The piston works in both directions. These compressors have high efficiency.

How is double acting used in a reciprocating compressor?

Double Acting In the double-acting type of reciprocating compressor, the sides of the piston are used for compression of air. On the one side, there is suction and compression takes place on the other side. Both the suction and compression take place on every stroke of the piston.

What are the main parts of a reciprocating compressor?

The single-acting reciprocating air compressor has only a single side of the piston and it is used for compression of air and another side is connected to the crankcase and it is not used for compression. 2. Double Acting In the double-acting type of reciprocating compressor, the sides of the piston are used for compression of air.

Where does the compression take place in a double stage compressor?

In the double stage air compressor, the compression takes place in two stages. In the first stage, the air is compressed in one cylinder and after that, it transferred to the second cylinder for the next compression. And in the end, the compressed air is stored in a tank.

What are the two types of air compressors?

According to the working of the piston, the reciprocating compressor divides into two main types. These two types are single-acting compressor and double-acting air compressor. In a single-acting air compressor, only one side of the piston works.
