Abstract

The invention discloses a rail-type automatic evaporator leak detector, which is used to detect whether an evaporator has an air leakage problem after the evaporator is machined and formed. The rail-type automatic evaporator leak detector comprises a top rail, a bottom rail, a traction line, a traction arm, a rail car, a gas booster pump, a leak detection pool, a connection pipe and a plug. When the rail-type automatic evaporator leak detector is used, the connection pipe sleeves one end of an evaporator pipeline, the other end or ends is plugged with the plug, the whole evaporator is placed on the rail car, the whole car is towed into the leak detection pool, then the pressure in the pipeline is increased through the gas booster pump so as to make the internal pressure greater than 2.8 Mpa, and the whole car stays in the pool for 30 minutes. If no bubbles emerge, then the evaporator is qualified, otherwise unqualified. The applied air pressure is slightly higher than the pressure in the pipeline during actual use, so that the use safety can be ensured and the phenomenon of liquid leakage is eliminated.

Description

technical field [0001] The invention relates to the field of refrigeration equipment, in particular to a device for detecting the airtightness of evaporator pipelines. Background technique [0002] The evaporator is an important device in refrigeration equipment. There is cooling liquid flowing inside the pipeline. In actual use, liquid leakage is not allowed. In the production process, it is necessary to perform air tightness testing on the produced leak detection device. , Existing detection method exists detection inaccurate, unscientific deficiency. Contents of the invention [0003] In order to overcome the above-mentioned deficiencies of the prior art, the present invention makes the following designs: the structure of the present invention: comprising top rail, bottom rail, traction line, traction arm, rail car, gas booster pump, leak detection tank, connecting pipe, plug, The traction arm is mounted on the top rail, the traction line is fixed on the traction arm, ...
