Question: What is air locking? Answer: If there is air inside the pump at the time of startup, and since the density of air is much lower than that of liquid, the centrifugal force generated by the air when the impeller rotates is also very small. This results in a low vacuum level at the center of the impeller, preventing the liquid from being drawn to that area; as a result, the pump cannot pump out liquid. The pump then experiences severe vibration, along with loud, harsh noises. This phenomenon is known as air locking. http://bbs.hcbbs.com/static/image/hrline/4.gif HaiChuan Network’s special May Day event, “Remembering the Glorious Moments,” warmly invites your participation. http://bbs.hcbbs.com/thread-1774529-1-1.html (Source: HaiChuan Chemical Forum) Summary post for HaiChuan Network’s special May Day event, “Remembering the Glorious Moments.” http://bbs.hcbbs.com/thread-1774532-1-1.html (Source: HaiChuan Chemical Forum) First round of voting for the “Creative Ideas” event (Use your mouse to influence the results). http://bbs.hcbbs.com/thread-1776507-1-1.html
Air is present during pumping, preventing the pump from performing work; a vacuuming phenomenon occurs
If there is air inside the pump at the time of startup, and since the density of air is much lower than that of liquid, the centrifugal force generated by the air when the impeller rotates is also very small. As a result, the vacuum level at the center of the impeller is low, preventing the liquid from being drawn to the center of the impeller; consequently, the pump cannot pump out liquid. The pump unit experiences severe vibrations along with loud, harsh noises. This phenomenon is known as air locking.
I want to learn *it a bit; I really don’t know: lol
I’ve learned it.* But how to solve gas entrapment?

Air binding: When a centrifugal pump is started, if there is air inside the pump, the low density of air results in a weak centrifugal force generated upon rotation; as a result, the low pressure created in the center area of the impeller is not sufficient to draw liquid from the storage tank into the pump. Hence, even though the centrifugal pump is started, it is unable to transport liquid. This phenomenon is known as gas entrapment
