What are the characteristics of the oxygen compressor?

Oxygen compressor refers to the compressor used to supercharge oxygen and realize the delivery. There are many types of oxygen compressors, such as centrifugal oxygen compressor, piston oxygen compressor, screw oxygen compressor and slide vane oxygen compressor. Different types of these oxygen compressors also have their own characteristics and different places of application. Then what characteristics does each of them have?

Centrifugal oxygen compressor

Piston oxygen compressor

Slide vane oxygen compressor

Centrifugal oxygen compressor

The principle of centrifugal air compressor is driven by the impeller gas do high-speed rotation, so that the gas centrifugal force, because the gas in the impeller diffuser flow, so that the gas through the impeller after the flow rate and pressure has been increased, the continuous production of compressed air.

Advantages of centrifugal oxygen compressor:

(1) Exhaust volume, uniform exhaust, no pulse air flow.

(2) The speed is high.

(3) No lubrication is needed in the machine.

(4) Good sealing effect, less leakage.

(5) There is a flat performance curve, the operation range is wide.

(6) Easy to achieve automation and large-scale.

(7) Wear parts less, less maintenance, long operation cycle.

Disadvantages of centrifugal oxygen compressor:

(1) Operation of poor adaptability, the nature of the gas has a greater impact on the performance of the operation. In the unit starting, stopping and running, the load changes greatly.

(2) The airflow speed is large, the flow passage parts have a greater friction loss.

(3) The surge phenomenon, the great harm to the machine.

(4) Centrifugal oxygen compressor applicable scope: medium and low flow, medium and low pressure occasions.

Piston oxygen compressor

Piston oxygen compressor is a kind of compressor that relies on reciprocating movement of piston to pressurize and transport gas.

Advantages of piston oxygen compressor

(1) Piston compressor is applicable to a wide range of pressure, regardless of the flow, can meet the required pressure;

(2) The piston compressor has high thermal efficiency and low unit power consumption;

(3) Strong adaptability, that is, the exhaust range is wide, and is not affected by the high or low pressure, can adapt to a wider range of pressure and cooling capacity requirements;

(4) The piston compressor on the material requirements are low, common steel materials, easy to process, the cost is lower;

(5) Piston compressor is relatively mature in technology and has accumulated rich experience in production and use;

(6) The piston compressor installation system is relatively simple.

Disadvantages of piston oxygen compressor

(1) The speed is not high, the machine is large and heavy;

(2) Complex structure, many wearing parts and large amount of maintenance;

(3) Exhaust gas is discontinuous, causing airflow pulsation;

(4）Large vibration during operation.

Piston oxygen compressor in various occasions, especially in the range of small and medium refrigeration, has become the most widely used refrigerator, the largest batch of a model.

Slide vane oxygen compressor

Advantages of slide vane oxygen compressor

The sliding vane compressor is simple in structure, easy to manufacture, easy to operate and maintain. It is almost perfectly balanced and vibration-free, so requires a small base. In addition, during the rotation, there are multiple unit volumes connected to the suction and exhaust pipes, so the suction and exhaust pressure pulsation is small, and it is not necessary to install a large air reservoir.

Understanding the characteristics of different types of oxygen compressors will help us to choose the most favorable type of oxygen compressor according to different characteristics.
