Barrel pump refrigeration unit

• Principle and product type of the barrel pump unit:

The high efficiency and energy saving fluorine pump liquid supply system is a refrigeration system that uses the mechanical action of the pump to transport cryogenic refrigerant liquid to the evaporator. After throttling, the cryogenic refrigerant liquid first enters the low-pressure circulation bucket with a certain liquid storage volume and a certain gas-liquid separation volume, and then transfers the cryogenic liquid with several times the evaporation amount to the evaporator of each warehouse with the fluorine pump. Most of the liquid is vaporized in the evaporator, and the rest is returned to the low pressure circulation barrel with the steam body through the return pipe. After the separation of gas and liquid, the steam body is sucked away by the refrigeration compressor, and the separated liquid and the new supplementary liquid equivalent to the evaporation amount are transported to the evaporator by the fluorine pump for recirculation.

• Advantages of the barrel pump unit:

1. The evaporator has high evaporative heat transfer efficiency and good cooling effect;

2. The circulating amount of refrigerant several times that of the evaporator makes the evaporator have sufficient wetting surface, which can play the heat transfer efficiency of all the evaporation area of the evaporator;

3. Due to the erosion of a large number of refrigerant, the evaporator pipe wall is not easy to form oil film, and its bottom is not easy to accumulate oil pollution, so that the heat transfer coefficient of the pipe wall can be improved;

4. For the evaporator with the same evaporation area, the cooling effect of the fluorine pump supply liquid is about 25-30% higher than that of the direct foot expansion supply liquid;

5. The mechanical action of the pump can overcome part of the resistance loss in the system to achieve long-distance liquid supply;

6. When the hot fluorine melt melts, the remaining liquid in the evaporator is directly discharged into the low-pressure circulation bucket. Then the fluorine pump can be restored, the storage temperature is fast and the operation is convenient;

7. The system operation is simple and reliable, which is convenient for centralized control and automation, and the operating condition of the refrigeration compressor can be improved
