Description
Technical field
The utility model relates to a kind of proof submersible sand discharging pump, belongs to fluid machines technical field.
Background technique
Proof submersible sand discharging pump is a kind of Pump and Electromotor disjunctor, and the pump series products worked under simultaneously slipping into liquid, generally carry out cooling motor by the water circulation outside electric machine casing, therefore existing proof submersible sand discharging pump is provided with cylindrical shell usually outside electric machine casing, flow in the cavity between cylindrical shell and electric machine casing by the cooling water of discharging in pump chamber, discharge from the osculum cylindrical shell after cooling motor.Due to existing proof submersible sand discharging pump, at cylindrical shell and the pump housing with hang between lid and do not arrange sealing, so that cylindrical shell and electric machine casing are fitted defective tightness, cause the race of cooling water to emit injection, and very easily long-pendingly become silted up, and cause vibrating noise very large.
Model utility content
For the problems referred to above that prior art exists, the purpose of this utility model is to provide a kind of cooling water of avoiding and runs the proof submersible sand discharging pump emitting and spray and reduce vibrating noise.
For achieving the above object, the utility model adopts following technological scheme:
A kind of proof submersible sand discharging pump, comprises the pump housing, motor, hangs lid and cylindrical shell, it is characterized in that: be provided with seal ring at the contact jaw of cylindrical shell and the pump housing and/or cylindrical shell and the contact jaw that hangs lid.
Preferably, described seal ring is U-shaped, is nested on the end of cylindrical shell.
Preferably, in the pump housing, be provided with impeller, described impeller is half-opened impeller or two blade impeller.
Preferably, in electric machine casing, be provided with grease chamber, in described grease chamber, be provided with double mechanical seal, separate to make oil and sewage.
Preferably, described grease chamber is provided with grease chamber's sealing cover, and described grease chamber sealing cover is provided with outside framework oil seal, enters in grease chamber damage mechanical seal to prevent dirt, silt etc.
Compared with prior art, the utility model is by arranging seal ring at the contact jaw of cylindrical shell and the pump housing and/or cylindrical shell and the contact jaw that hangs lid, make cylindrical shell can be stabilized in the pump housing and hang between lid, not only effectively can solve the fitting tightly of cylindrical shell and electric machine casing, noise and vibration when reducing operation, and can effectively prevent the cooling water in cylindrical shell from electric machine casing and the pump housing, hang between lid gap run and emerge, and cooling water can only be discharged from the osculum cylindrical shell, ensure that the abundant cooling effect of cooling water to motor; In addition, the utility model also has the advantages such as structure is simple, reliable, easy to maintenance, long service life, has practicability.
