The utility model can also adopt following technical measures:
The detection sensing element of described water inlet-proof alarm or power-off protection apparatus is two electrodes, and it is separately fixed in the winding inner chamber bottom and cable separate cavities of housing.
The detection sensing element of described anti-overtemperature alarm or power-off protection apparatus is the temperature relay of normally-closed contact, and it is fixed on the stator winding of winding inner chamber of housing.
Advantage and the good effect that the utlity model has are: since on the end face of upper end cover and bottom end cover, be respectively arranged with sealing provide the separate cavities and the grease chamber of second road sealing for cable; and on the external part of the axle in the grease chamber double-deck single mechanical end face seal is housed; for motor provides dual anti-water inlet protection anti-water inlet and anti-overtemperature alarm or power-off protection apparatus are housed also in motor in addition; thereby the sealing property of motor is good; the reliability height; in addition because the fairlead of cable is positioned at the side of motor upper end; so promptly can vertically install and use; also can horizontally install and use; the convenient submergence depth of adjusting at any time; in sum; the utility model can be in the medium-term and long-term stable operation of sewage, for sewage disposal provides the reliable equipment that is suitable for.
