Water seal principle of ammonia tank

The principle of water seal in ammonia tank is to keep a certain height of water in equipment or container. The water inlet pipe extends into the storage water, and the water outlet pipe remains on the water surface. The intake air enters the water storage by the pressure difference in the water inlet pipe, then escapes from the water and enters the water outlet for discharge. When the ammonia tank is loaded, it is easy to form negative pressure inside the ammonia tank. When the pressure is lower than -0.5KPa, a large amount of air will enter the water seal to make up the pressure.
