Ace: industry to help master blows itA drainage ditch next to my apartment building, I live on the first floor, air conditioning maintenance company to check that the outdoor machine is "copper ditch biogas corrosion, broke a lot of holes, Daikin air-conditioning outdoor machine copper tube corrosion leakage of fluorine, need to disassemble the back field maintenance, I have called for new air conditioning for only 2.5 years of the Jin Dynasty," ditch marsh gas erosion "first heard, there is such a thing? Baidu search for many have not seen this example, you heave your master! What can be painted after the repair can effectively prevent corrosion?!
There must be a statement of corrosion. Methane (CH4) is, by definition, a weak acid. Long periods of gas erosion can react with copper tubes and change their properties. Besides, the copper tube is pressurized, which accelerates the speed to a certain extent. Corrosion prevention: epoxy coal tar cold belt first winding; insulation use polyurethane insulation pipe, seal to do well.
The next time you install the outdoor machine, you'd better set the high point! You should hold it close to the ground when you install it! Rain is corrosive! The corrosion of drains mainly comes from urea!AskIt's three meters from the ground!Chasing the answerThen you put a tube outside the brass tube!
If the hole is not too large, it can be filled; use brazing to fill it; other types of materials or methods do not solve the problem.Air conditioning during normal use, low pressure pipeline in the refrigerant pressure more than 5 kilograms in the high-pressure refrigerant pressure above 15 kilograms, with ordinary glue, hot melt soldering, the ways to do the pressure bearing performance, even if the bearing performance can do air conditioning during the operation of the pipeline will be vibration occurs, will soon leak again.The hole is not large, when the need for brazing to fill the hole in the pipeline before the refrigerant recovery or to let go all the outdoor machine inside, remove the holes in the copper brazing, the flame temperature due to increase, by welding to trap quickly, after completion leakage should give air conditioning with high-pressure gas leak detection in general, high pressure gas pressure above 30 kilograms, then vacuum, filling the standard amount of refrigerant.If the damaged hole is larger, it can not be welded to fill the hole, the pipeline should be broken in the broken place, welded joints with joints to connect, or directly replace the new brass tube.
