What problems should be paid attention to when designing and using Co2 compressor?

(1) The critical temperature of carbon dioxide is high, and it can be liquefied at 31.3°C and 7.14MPa. When used in winter, the cooling temperature between stages cannot be too low;

(2) When carbon dioxide is below 60MPa, it is conducive to the compression of gas;

(3) Due to the relatively high density of carbon dioxide gas, it is not appropriate to use an excessively large average speed of the piston, otherwise the valve resistance will be large;

(4) Carbon dioxide gas contains a small amount of water and is highly corrosive, so the gas valve, cooler and buffer tank must be made of stainless steel.

How to install Co2 compressor products?

1. Installation: During the installation process, please refer to the size of each interface in the technical parameters to avoid foreign matter entering the pump and keep the inlet and outlet clean.

2. Air source quality standard: Please choose a clean air source to ensure the pump can work continuously and stably.

3. Air source lubrication: When the Co2 compressor leaves the factory, all moving parts have been coated with appropriate amount of lubricating oil. Generally, lubrication is no longer required. If the dry compressed gas is used for a long time to drive, it is recommended to add an appropriate amount of lubricating oil to the oil cup of the two-piece unit. oil for oil mist lubrication.

4. Air source pressure: The minimum driving pressure of the Co2 compressor is 1.5-2bar, and the design driving pressure is 10bar. Recommended air pressure between 6-8bar. The required operating pressure can be achieved by adjusting the pressure of the pressure regulating valve. The driving pressure of the pump cannot exceed 10bar. If it is driven by pipeline gas, there must be a reliable pressure reducing valve and a safety valve.

5. Connecting pipeline: According to the output pressure and flow of the Co2 compressor, select the appropriate inlet and outlet connecting pipeline to ensure that it can withstand the output pressure and flow of the pump.

6. The output pressure of the Co2 compressor is determined by the pressure of the driving air source. Calculated according to the booster ratio of the booster pump, the booster ratio is 25:1.

What are the types of Co2 compressors?

1. Volumetric type: The volumetric compressor realizes the processes of suction, compression and exhaust by changing the volume of the working chamber. Positive displacement compressors are divided into reciprocating and rotary types according to the operation form of their working parts. The former piston reciprocates in the cylinder, while the latter is the working part that rotates in the cylinder. But at present, the most widely used in the refrigeration industry is the piston-type Co2 compressor, and there are dozens of models.

2. Speed type: The speed type compressor relies on the high-speed rotating working impeller to do work on the steam to increase the pressure and complete the task of transporting the steam. This type of compressor is divided into centrifugal type and axial flow type according to the flow direction of the steam, among which the centrifugal type is the most widely used.
