Description

Technical Field

[0001] This utility model relates to the technical field of refrigerant filling production equipment, specifically a high-power vacuuming device used before refrigerant filling. Background Technology

[0002] In the production and maintenance of refrigeration systems, the vacuuming operation before refrigerant filling is a key step to ensure system performance and stability.

[0003] Traditional methods of vacuuming refrigerant bottles before filling rely mainly on manual operation. Personnel need to place each refrigerant bottle next to the vacuuming equipment, connect the vacuum hose to evacuate the gas, and then manually remove the evacuated bottle and replace it with a new one to be evacuated. The process is cumbersome and time-consuming. Therefore, we propose using a high-power vacuuming device before refrigerant filling. Utility Model Content

Several support rods are provided at the top of the base, and a fixed ring is fixedly connected to the top of each support rod. A vacuum suction pipe is provided at the output end of the vacuum pump body. A rotating ring is rotatably connected to the wall of the fixed ring. Several toothed grooves are provided on the inner side wall of the rotating ring. Several connecting blocks are fixedly connected to the outer wall of the rotating ring. A can-bearing frame is fixedly connected to one end of each connecting block. A motor is installed on one side of the top of the fixed ring. A transmission rod is fixedly connected to the output end of the motor. A transmission gear is fixedly connected to the wall of the transmission rod, and the transmission gear meshes with several toothed grooves.
