A bend pipe connects the outlet of the single-stage centrifugal pump to the inlet; what is the purpose of this pipeline? It shouldn’t be acting to generate a balancing axial force.
Check if it reaches the end face of the pump; if so, it is the seal tube
Personally, I think it doesn’t serve a balancing function; rather, it acts as a water seal.
It might be a return pipeline, to protect the pump
What was said upstairs is correct; if it’s located on the end face of the pump, then it’s a sealing pipeline, which is present in most pumps. 1# haorui0911
The one that returns to the inlet should be the minimum reflux line; if it is on the end face opposite the bottom inlet, then it is a mechanical seal.
