My home pump every time you use, you should use your hand to dial the impeller, or else the impeller will not turnExcuse me, what's the matter?,
What is the type of pump in your home, single-phase or three-phase, single-phase may be the capacitor is not good?
There are so many reasons that it is likely that the bearings will not work and the rotor is eccentric
Could there be a short circuit, three phase three-phase voltage? Do not lose sight of it, or it will burn quickly
