The freezer price - Freezers leak detection do you know how to do

< p > freezers - price Freezers leak detection you know how to do it in the commercial freezer in the process of maintenance, have an important examination, is the leak detection. Must have a lot of clients should be heard, so specific how to leak detection, need to use what tools, estimated that not many people know it. Let freezers prices to tell you these, then, in the future of air-conditioner maintenance, also can use. First is the need to tool: the 3-way valve (pos. No. Several, nitrogen bottles of 2 ( With pressure reducing valve) , vacuum pump, hose, hexagon wrench, cutter, oxygen welding equipment, soap water, containing water container has funnelled freezer, refrigeration system. With these, the following will begin to leak detection, steps are as follows: 1. Freezers leak detection for high and low pressure section (1) use oxygen welding methods will be taken out from the capillary from the filter drier, the compressor suction, exhaust pipe with cutter cut. (2) capillary connected to the low pressure table, air suction pipe and pick up a bottle of nitrogen three-way valve connected to low voltage side wall filter drier and high pressure table joins, exhaust pipe and the other one has a nitrogen bottle of three-way valve connection into a high side. 。 (3) will open two nitrogen gas bottle, first adjust their pressure reducing valve, low voltage side adjustment to 0. 4 - 0. 8 mpa, high side to adjust to 1. 8 mpa, then three way valve open to high and low side injection of nitrogen respectively. (4) with soap and water leakage, low voltage side of evaporator part can be put into water leakage in the container.
2. Vacuum leak detection method (1) of air-conditioner compressor process pipe on the three-way valve with low pressure table, the 3-way valve (pos. No. On the other end of the hose joint on the vacuum pump suction mouth. (2) open the vacuum pump power vacuum, to observe the low pressure gauge pressure drop to 133. 3 pa closed after three-way valve valve, and then turn off the vacuum pump power, observe whether pressure is increased again after 12 h. If the pressure shows has funnelled refrigeration system. (3) if the continuous vacuum l - After 2 h, pressure is less than 133. 3Pa( Vacuum pump outlet is still gas discharge) , also has funnelled instructions. Finally is the air-conditioner leak detection time considerations ( 1) When the low voltage side leakage must first tooth can be put into the water after the injection of nitrogen leak detection of water in the container. ( 2) When vacuum pump leakage, should pay attention to the sealing connection parts, put an end to by mixes up phenomenon caused by misjudgment caused by vacuum degree is not enough. In addition, when the pressure reaches 133. 3 pa should be shut the 3-way valve (the valve, and then disconnect the vacuum pump power to prevent the air flow, so that cause misjudgment. These are in the process of the whole of air-conditioner leak detection tools and methods, but in the end is the matters needing attention, all of these need to be familiar with, can better check the freezer. < br / > < / p >
