Rotary vane pumps for pumping flammable new refrigerants are specially designed to handle flammable refrigerants. These vacuum pumps are typically of rotary vane design and are able to operate efficiently in the low to medium vacuum range and are suitable for maintenance and installation in air conditioning and refrigeration systems.
Rotary vane vacuum pumps for pumping new combustible refrigerants
1.Principle of operation
The working principle of rotary vane vacuum pump is based on volume change to realize pumping. A rotor is mounted eccentrically in the pump chamber, the outer circle of the rotor is tangent to the inner surface of the pump chamber (there is a very small gap between the two), and the rotor groove is equipped with rotary vane with spring. When the rotor rotates, the rotor blade slides against the inner wall of the pump chamber under the action of spring tension and centrifugal force, thus separating the pump chamber into different parts. With the rotation of the rotor, the volume of the space connected with the suction port gradually increases, and the gas is inhaled; while the volume of the space connected with the exhaust port gradually decreases, and the gas is compressed and discharged.
2.Features and Advantages
Combustible new refrigerant extraction capacity:
The vacuum pump is specially designed to remove new combustible refrigerants, ensuring no safety issues during maintenance or charging.
Efficient pumping:
The vacuum pump has a high pumping rate and ultimate pressure, enabling the required vacuum level to be reached quickly.
Compact structure:
The unit is compact and lightweight, making it easy to carry and operate.
Stability and durability:
The rotary vane vacuum pump has simple structure, stable operation and high durability, which is suitable for long time work.
3.Application Scenarios
Portable refrigerator maintenance:
During the maintenance of portable refrigerator refrigeration system, the vacuum pump can be used to pump out the old refrigerant and the air in the system to ensure the smooth charging of new refrigerant.
Other refrigeration equipment:
In addition to portable refrigerators, the vacuum pump can also be used for the repair and maintenance of other refrigeration equipment, such as automobile air conditioners, cold storage, etc.
4.Precautions
Flammability:
As the new refrigerant is flammable, when using the rotary vane pumpable pumpable flammable new refrigerant vacuum pump, make sure the workplace is well ventilated to avoid fire or explosion.
Operational Specifications:
The operator should be familiar with the use of the vacuum pump and precautions, follow the relevant operating regulations to ensure the safe operation of the equipment.
Maintenance:
Regularly carry out maintenance on the vacuum pump, check the wear and tear of the rotary vane, spring and other parts, and replace the damaged parts in time to ensure the normal operation of the equipment.
