Why can’t the liquid be pumped up when there is gas in the pipe?
Thread Content
There is a section of gas inside the pipe, above the outlet pipe; the pipe is horizontal (the rubber hose is placed horizontally). The solution is industrial hydrochloric acid, and we use a rubber hose to deliver the acid. Upon inspection, there is a section of gas, with liquid present at both ends of this gas section, but the positions of the liquid do not change. What could be the reason for this? Is the individual analysis that the pressure of the gas plus the pressure of the other side of the gas is greater than or equal to the pressure of the pump? Right? Please help analyze it. Please solve it
Check the effect by exhausting it； Gases are more compressible than liquids, so they cannot be pushed away
I don’t think it’s that complicated; it’s simply that the pressure used for delivery isn’t sufficient, and it has nothing to do with that mass of air. Without this surge of energy, it’s impossible to get through. Losing brings enough pressure; this attitude is nothing but trying to stop a train with one’s arms
Based on what I’ve said, if it was possible to make the call in the past but not anymore, there is a possibility of airway obstruction. It must be that the sum of the static pressures of the liquids at both ends is greater than the pump’s head. It is difficult to determine because no specific piping diagrams or information regarding the gases in the pipes are provided. When the piping system has vertical sections, air blockage is entirely possible. Is it clear now that I said this? If necessary, I can use a legend to show you.
An air barrier is formed; as long as the pressure is sufficient, it is possible to push, thereby gradually driving the gas out.
If acid is discharged from a sump, gas in this pipeline may cause an air blockage; if it is pumped, please check: 1. Is there a problem with the pump? 2. What is the height at which you are pumping? Compare this height with the pump’s head pressure.
Pipes are designed for liquids; when used with gases, the resistance is too high.
Two directions: First, check whether the pump is working properly; generally, this type of piping does not cause air blockages. The second test checks whether there is any downward flow behind the bubbles; since hoses are used, it is very likely that there will be downward flow even when they are placed horizontally, resulting in air resistance ； Try the exhaust again.
Specialized terms need to be properly controlled; otherwise, not only will shooting be impossible, but the transfer pump will also get damaged
