How does the oxygen compressor work?

If your doctor recommends that you use an oxygen concentrator for oxygen therapy, you may use an oxygen compressor to increase the amount of oxygen stored. Do you have questions about how the oxygen compressor works? Below I will show you how the oxygen compressor works in our lives.

How the oxygen compressor works？

The crankshaft drives the connecting rod, the connecting rod drives the piston, and the piston moves up and down. The piston movement changes the volume inside the cylinder. When the piston moves downward, the cylinder volume increases, the intake valve opens, the exhaust valve closes, the air is sucked in, and the intake process is completed; when the piston moves upward, The cylinder volume is reduced, the outlet valve is opened, the intake valve is closed, and the compression process is completed. It is a positive displacement compressor that changes the internal volume of the compression chamber by one or several reciprocating pistons.

Oxygen compressor workflow

The oxygen to be compressed takes several steps to compress successfully. After passing through the filter, the intake solenoid valve, and entering the first stage cylinder of the compressor, after first-stage compression, it is discharged to the first-stage cooler for cooling, and then discharged to the second-stage cylinder for compression and cooling... until the fourth-stage cylinder is cooled and cooled and then passed through the check. The valve is discharged. The cylinder and cooler of the compressor are cooled by a separate fan blower. The unloading solenoid valve is arranged on the final stage of the compressor. When the machine is shut down, the pipeline and the gas in the cylinder are emptied, which is prepared for the next light load start. If necessary, the vented gas can be connected to the intake line.

This process can be divided into four processes of expansion, suction, compression, and exhaust.

1.Expansion: When the piston moves to the left, the volume of the cylinder increases, the pressure drops, and the residual gas originally remaining in the cylinder expands.

2. Suction: When the pressure drops slightly less than the gas pressure in the intake pipe, the gas in the intake pipe pushes the suction valve into the cylinder. As the piston moves to the left, gas continues to enter the cylinder until the piston moves to the left end.

3. Compression: As the piston turns to the right, the volume of the cylinder gradually shrinks, thus starting the process of compressing the gas. Since the suction valve has a back-stop effect, 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 has a back-stop effect due to the discharge valve and cannot flow into the cylinder. Therefore, the amount of gas in the cylinder is kept constant, and only because the piston continues to move to the right, the air volume in the cylinder is reduced, and the pressure of the gas is continuously increased.

4. Discharge: As the piston moves to the right and the pressure of the compressed gas rises slightly to the gas pressure in the outlet pipe, the gas in the cylinder opens the spring of the exhaust valve into the outlet pipe and continuously discharges until the piston moves. Until the end of the right. Then, the piston starts moving to the left again, repeating the above action. The piston continuously reciprocates in the cylinder to allow the cylinder to recirculate and exhaust the gas. Each reciprocation of the piston becomes a working cycle, and the distance that the piston passes each time or once is called the stroke.

Summary

Oxygen compressors can be used as an auxiliary medical device to help those who need oxygen. Such a compressor can be used in daily life and combined with living equipment. Similarly, what you don't know is that nitrogen compressors and hydrogen compressorscan be used officially.
