so that the calorimeter can restore accurate testing!

Firstly, we need to prepare some tools: oxygen bombs, oxygen, water, sealing rings, and a small wrench. Then, follow the steps below:

1. Fill the oxygen bomb with oxygen and carefully place it in the water. If the oxygen bomb emits bubbles in the water, it indicates that it is leaking air.

2. Find the location of the air leakage and replace the corresponding sealing ring. The oxygen bomb is equipped with three sealing rings: large, medium, and small. Select the corresponding size of sealing ring according to the location of the air leakage.

3. Start replacing the sealing ring. Firstly, open the oxygen bomb, locate and replace the large sealing ring. Usually, the large-sized sealing ring is the most prone to air leakage and often needs to be replaced.

4. Use a small wrench to rotate counterclockwise and remove the oxygen bullet. Then, locate and replace the small sealing ring inside the oxygen warhead. Note that the small sealing ring may not be easy to install, it can be lubricated with a little water.

After replacing all the sealing rings, install the oxygen bomb back and tighten it with a wrench.

6. Finally, refill the oxygen bomb with oxygen and place it in water to check for any remaining leaks. If there is no air leakage, then you can use it with confidence.

The above are the detailed steps to check for oxygen bomb leakage and replace the sealing ring. If your calorimeter also encounters the same problem, why not try this method! Remember to pay attention to safety during operation to avoid accidents.
