Rapid leakage detection method for copper pipe in lithium bromide refrigerating machine chamber

Abstract

A quick leak detection method for copper tubes in the cavity of lithium bromide refrigerators. The invention belongs to the technical field of maintenance of heat exchange facilities, and in particular relates to a rapid leak detection method for copper pipes in a heat exchange cavity of a refrigerator. The leak detection method is as follows: Replace the inspection door on the shell containing the heat exchange cavity with a transparent material door, fill the gap between the shell and the heat exchange cavity of the refrigerator with clean water, and then fill the heat exchange cavity with a pressure greater than the water pressure. The leak location can be determined by observing the position where the bubbles emerge from the heat exchange copper tube through the transparent door. The invention seldom changes equipment, consumes less funds, and has a simple and easy detection method with low labor intensity, can visually find specific leaking copper pipes, and greatly improves detection efficiency.

Description

technical field [0001] The invention belongs to the technical field of maintenance of heat exchange facilities, and in particular relates to a rapid leak detection method for copper pipes in a heat exchange cavity of a refrigerator. Background technique [0002] The lithium bromide refrigerator has three main heat exchange chambers, and the chamber is covered with more than 2,800 heat exchange copper tubes (about 3 meters long). All copper tubes are tested one by one, the special equipment used for testing is more complicated, the testing operation technique is very difficult, the labor intensity is high, it is difficult for ordinary workers to master, and the testing takes a long time, which seriously affects the production progress; if the new device is completely replaced Then it costs a lot of money and takes a lot of time, which is unbearable for ordinary production enterprises. For example, the lithium bromide refrigerator used by Zhaotong Cigarette Factory is produce...

[0002] The lithium bromide refrigerator has three main heat exchange chambers, and the chamber is covered with more than 2,800 heat exchange copper tubes (about 3 meters long). All copper tubes are tested one by one, the special equipment used for testing is more complicated, the testing operation technique is very difficult, the labor intensity is high, it is difficult for ordinary workers to master, and the testing takes a long time, which seriously affects the production progress; if the new device is completely replaced It costs a lot of money and takes a lot of time, which is unbearable for ordinary production enterprises.

For example, the lithium bromide refrigerator used by Zhaotong Cigarette Factory is produced by a joint venture. During the production process, the heat exchange copper tube leaks. Every time the manufacturer or foreign experts use advanced equipment, it takes about 15 days to investigate and deal with the leak. In addition to spending a lot of testing costs
