The inspection method is as follows:
If the motor is running, submersible pumps produce "carbolic" sound, and the cycle is proportional to the speed, and feel the trouble when the rotor is rotated by hand, is a bit astringent or avulsion phenomenon on the bearing raceway; if the intermittent "哽 哽 "sound, turning the rotor by hand when there is an indefinite dead, usually submersible pump ball cage damage, the inner ring ruptured or ball broken. In the event of the above situation, the bearing must be replaced to avoid any further damage.
Submersible pump in the demolition before the end cover should be marked with the seat at the seat mark. In order to repair the assembly as it is, it will not cause assembly errors caused by the shaft is not the heart; in the removal of the submersible pump impeller and bushings and other components, it should be noted that must not hard hit hard impulse, available thermal expansion principle, heating edge Tap or use "Rama" and other tools to remove.
Winding burn should be analyzed for reasons (overload, card pump, lack of phase, leakage leakage short circuit, etc.), remove the submersible pump motor windings, do not make the silicon steel tilt shift and burrs and other phenomena, so as not to knock the new windings knock " Bell "caused by grounding or short circuit fault. Rewinding the new coil, the enameled wire and insulating paper must be selected regular manufacturers, due to the submersible pump motor heat rating is generally E, B level. Must pay attention to its level of heat corresponding. Low insulation thickness should be sufficient, and to pad inserted in place. Winding off the assembly line, be careful not to scratch the stator core coil, but also avoid using crossed repeatedly crossed.
