The invention discloses a nitrogen charging device which comprises a frame (1), a plurality of nitrogen charging pipelines (63), a cyclical feed unit, a drive unit, a height adjuster and a nitrogen feed unit (4), wherein the nitrogen charging pipelines (63) are arranged on the frame (1), each nitrogen charging pipeline (63) is provided with a nitrogen inlet port (61) and a nitrogen outlet port (631), and the nitrogen outlet port of each nitrogen charging pipeline is opposite a port of a to-be-charged nitrogen U pipe; the cyclical feed unit is arranged on the frame (1) and drives the nitrogen charging pipelines (63) to rotate cyclically, and the drive unit drives the cyclical feed unit to rotate cyclically; the height adjuster is used for adjusting the height of the nitrogen charging pipelines (63); the nitrogen feed unit (4) is arranged on the frame (1) and provided with a nitrogen charging port (45); and the nitrogen charging port (45) of the nitrogen feed unit (4) is matched with the nitrogen inlet port (61) of each nitrogen charging pipeline (63). According to the structural design, the nitrogen charging device disclosed by the invention can effectively solve the problems of time consuming, labor consuming and low work efficiency in the nitrogen charging process.
Description
technical field [0001] The invention relates to the technical field of air conditioner processing, and more specifically relates to a nitrogen filling device. Background technique [0002] Such as figure 1 As shown, in the process of processing the air conditioner, it is necessary to weld the port of the U-shaped tube 01 used to transmit the refrigerant of the condenser to one end of the arc-shaped elbow 02, wherein the two ends of the elbow 02 are respectively Weld with the two ports of the U-tube 01. In order to prevent oxidation and corrosion on the inner wall of the U-shaped tube, it is generally necessary to fill the inside of the U-shaped tube with nitrogen before welding to remove the air inside the U-shaped tube, thereby preventing oxidation and corrosion on the inner wall of the U-shaped tube. [0003] At present, the method of filling nitrogen into the U-shaped tube mainly adopts the way that the staff hold the nitrogen filling equipment to fill the U-shaped tube...
