The working process of customized reciprocating compressor factory
The customized reciprocating compressor factory has cylinders, pistons, and valves. The working process of compressed gas can be divided into four processes: expansion, suction, compression, and exhaust. For example the cylinder of a single-suction compressor, this customized reciprocating compressor factory only has a suction valve and an exhaust valve in one section of the cylinder, and the piston only takes in and exhausts air once for each reciprocation.
(1) Expansion: When the piston of the customized reciprocating compressor factory moves to the left, the volume of the cylinder increases, the pressure drops, and the residual gas remaining in the cylinder expands continuously. (2) Inhalation: When the pressure drops to slightly less than the gas pressure in the intake pipe, the gas in the intake pipe will push open the intake valve and enter the cylinder. As the piston moves to the left, gas continues to enter the cylinder until the piston moves to the left end (aka left dead center).
(3) Compression: When the piston of the customized reciprocating compressor factory moves to the right, the volume of the cylinder is gradually reduced, thus starting the process of compressing the gas. Due to the non-reverse effect of the suction valve, the gas in the cylinder cannot be returned to the inlet pipe, and the gas pressure in the outlet pipe is higher than the gas pressure inside the cylinder, and the gas in the cylinder cannot escape from the exhaust valve to the outside of the cylinder. The gas in the outlet pipe cannot flow into the cylinder due to the non-reverse effect of the exhaust valve. Therefore, the amount of gas in the cylinder remains constant, but because the piston continues to move to the right, the gas-containing space (volume) in the cylinder is reduced, and the pressure of the gas continues to rise.
(4) Discharge: As the piston moves to the right, when the pressure of the compressed gas of the customized reciprocating compressor factory rises to slightly greater than the gas pressure in the outlet pipe, the gas in the cylinder pushes the spring of the discharge valve into the outlet pipe, and the gas in the cylinder pushes open the spring of the exhaust valve into the outlet pipe, and the pressure of the compressed gas is increased. Continue to discharge until the piston moves to the right end (aka right dead center).
Then, the piston of the customized reciprocating compressor factory starts moving to the left again, repeating the above action. The piston reciprocates continuously in the cylinder so that the cylinder reciprocates the suction and discharge of gas. Each reciprocation of the piston becomes a working cycle, and the distance traveled by the piston each time it goes back and forth is called the stroke.
Through the above introduction and analysis of the working process of a customized reciprocating compressor factory, hope it helps you.
