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

Abstract

The invention relates to a rapid leakage detection method for a copper pipe in a lithium bromide refrigerating machine chamber, belongs to the maintenance technology field of heat exchange facilities and particularly relates to the rapid leakage detection method for the copper pipe in a refrigerating machine heat exchange chamber. The method comprises steps that an access door of a casing accommodating the heat exchange chamber is replaced by a transparent door, clean water is filled between the casing and the refrigerating machine heat exchange chamber, gas with pressure greater than water pressure is injected into the refrigerating machine heat exchange chamber, the heat exchange copper pipe is observed through the transparent door, if a position of the heat exchange copper pipe bubbles, the position is determined to be a leakage place. The method is advantaged in that the equipment is only slightly changed, cost is low, the detection method is simple and easy, labor intensity is low, the specific leakage position of the copper pipe can be visually discovered, and detection efficiency is greatly improved.

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
