Is the order of the examination: ?
2. sealing checks: The gap after mechanical and sealed box wears away is too big, if maintain not in time, soggy hind leakage of electricity brings about water electric conduction, puncture winding, cause sumbersible pump burn down. After general job 300h, will turn on the water unscrew of heal snail a place of strategic importance undertakes checking.

If grind an attaint, answer to be repaired to the manufacturer that has corresponding technology and facility. Normally barometer of usable pump series connection aerates, will examine the sealed case of pump, fill baric force to be 19.6kPa, continuously 10min, if pressure expresses a needle to be not moved, regard as sealed and good.
Does 3. insulation circumstance check: ? Quan? Sumbersible pumpItself leakage of electricity, soggy hind can create leakage of electricity of wiring box alternate with and housing incessant predestined relationship. Because this answers to often check the insulation resistance of sumbersible pump, should be in 0.5 million Europe commonly above, under 0.5 million Europe, sumbersible pump must not be used.
The examination of 4. protector: Coil of tripping operation of sumbersible pump protector burns caustic, lost the protective effect that plays sumbersible pump to the well. Does tripping operation coil burn the main reason: of caustic?
