What are the common leak detection methods for industrial chillers? The editor now counts a few small ways to tell you:

1. Test paper leak detection method Generally, phenolphthalein test paper is used to test the system's welds, flanges, threaded connections and other places for leaks. Moisten the test paper and approach the test site. If it turns red, it means that there is ammonia leakage. Litmus paper that turns blue when exposed to ammonia can also be used.

2. Halogen blowtorch leak detection method Halogen blowtorch is a common tool for leak detection in Freon refrigeration systems. The method of use is as follows:

 1. Add alcohol: first unscrew the base, add anhydrous alcohol with a purity of not less than 99.5% to the inside of the barrel, but the amount of injection should not be too much, just fill 1/2 to 3/4 of the volume of the lamp tube. Yes, the base should be tightened quickly afterwards.

 2. Light a fire: turn the handwheel to the right, close the valve core, fill the wine glass, and then light it to heat the lamp tube and the upper part of the blowtorch. After heating a little, check whether the blowtorch is leaking.

 3. Fire: When the alcohol in the beaker is almost burnt out, turn the handwheel to the left and ignite the volatilized alcohol in the nozzle in the flame circle. At this time, the suction hose of the halogen lamp emits gas inhalation. Sound, you can start leak detection with lights.

 4. Use: When testing, move the nozzle of the suction hose close to the inspected place and move it slowly. If there is Freon gas leakage, it will decompose when it meets the flame. At this time, the orange-red flame will turn green and the flame color will change. Depending on the amount of Freon leakage, the darker the color indicates the more serious Freon leakage.
