There is a noise inside the pipe; I seek advice from experts
Thread Content
It is a horizontal tank filled with high-temperature heat transfer oil, equipped with a pressure switch at the top (with a condensation coil and M20 pipes). It seems that the coexistence of gas and liquid is causing the knocking sound, which in turn causes the pointer of the pressure switch to fluctuate according to the frequency of these knocks. How can this knocking noise be eliminated? Why do all the structures with 6 tanks have the same design, yet only this one makes noise?
It’s possible that water got in, and it vaporized rapidly at high temperatures
Water hammer occurs due to unexpelled gas
Six identical storage tanks; is the location of this tank different from those of the others?
There can’t be any water inside; if anything, it’s liquid heat transfer oil
There is a pressure transformer nearby, and the pressure is very stable. Only the condensation ring makes noise; the pressure switch will change in response to those noises.
The pressure tapping points are in the same location, and the installation structure is the same as well.
Bro Pig, doing things that only provide temporary solutions rather than addressing the root cause isn’t something you should do! ;P
Do these six tanks follow a parallel or series process? It would be better if you drew a schematic diagram so it’s easier to understand!
It’s possible that the container making noise was built in an inauspicious location; one should find a Taoist priest or monk to recite some scriptures and burn yellow paper to drive away evil spirits. If a tower is built next to the tank*.
