Description
Affiliated technical field
The utility model belongs to submersible pump.
Figure viewed from behind technology
Submerged pump in the past, submersible motor, mechanical seal, pump case, single blade impeller, arrange (seeing agriculture project newspaper " Procedure of Single-channel Pump experimental research " in March, 1994) motor casing from top to bottom and adopt gray iron casting, when the diving operation, there is water to cool off in the motor casing outside, but, can only be pumped to clear water because of the silt particle proportion in the water deposits greater than water.Walked when submersible motor surfaces, just to have lost outside the water by pump drainage when water bunker level and cool off.This moment, the sewage silt particle concentration of pump pump drainage also increased thereupon, the just fully loaded or overload operation by the change of liquid medium concentration of pump motor.Though the advantage of single blade impeller is that nothing obstruction and anti-prehensile are good, because its runner of single blade impeller is not axisymmetric, pulse in service in addition goes out stream, and radial force, vibration force are very big.Thereby single blade impeller is difficult to obtain strict accurate quiet, dynamic balancing and handles, and very easily produces vibration and makes also sharply the heat up heating and make its acceleration impaired of its motor bearings, finally because of motor, bearing overloading, overheated burning.
Summary of the invention
The utility model purpose is: for fear of the generation of above-mentioned defect situation, provide a kind of pair of stirring to bring down stocks the desilting submerged pump automatically, when overcoming pump motor and it being surfaced because of being evacuated to drawdown, motor, the heat up defective of heating and stir the triplate line system that catchments of the anhydrous outer cooling of bearing by spray titter water, stir titter the water stirring fan nozzle of circle hole shape nozzle and lower end, the right pipeline end by titter the water of lower end, left side pipeline end, spray titter water has stirred the silt particle sewage that the pump body deposits down outward on every side, and be located at the axial flow paddle of annular setting-out volute chamber below, then stirred the silt particle of pump below deposition, played dual stirring and bring down stocks the desilting effect automatically.Solve submerged pump and moved the difficult problem that overall process can both balancedly be pumped to high concentration mud sand sewage constantly.
The technological scheme that its technical problem that solves the utility model adopts is: the desilting submerged pump is brought down stocks in this pair of stirring automatically, on pump body and outlet part flange, be provided with the triplate line system that catchments that is connected with fastening piece, flange arrangement, pump body lower flange is provided with titter the water stirring circle hole shape nozzle of the lower end, pipeline end, the left side that connects by the card plumber block and titter the water of the last lower end of the right pipeline stirs fan nozzle, can spray titter water and stir the mud sand that the pump body deposits down outward on every side.In the pump body, be provided with motor casing external ring cavity, motor windings, rotor axis of electric, this axially below successively order pass biserial angular contact bearing, mechanical seal, annular setting-out volute chamber and two blade impeller on the motor lower end cap, below be provided with volute chamber annular suction port, the most last lower end is provided with the axial flow paddle.Their top-down arrangements assembling adopts the bolt fastener structure to connect, and two blade impeller in the volute chamber and axial flow paddle be by axle, key connect in proper order and with abnormity nut, floor clip with its fastening being locked on the rotor axis of electric.During this axle rotation, the axial flow paddle has just stirred the sewage silt particle of pump below deposition.
Be provided with the runner symmetry in the voluted type annular setting-out volute chamber that the area of this section half garden shape and each section equates, operate steadily, be difficult for producing the two blade impeller of characteristics such as vibration, liquid water stream upwards extrudes a mouthful runner hole by distribution several small flows in shape section garden, half garden heart line top in the volute chamber during rotation, the left and right nozzle of triplate line system that catchments of flowing through, can spray titter water and stir the silt particle that the pump body deposits down outward on every side, the exhaust port that flows to side, cut water place is taken over the sewage silt particle that can discharge big flow.Be provided with to put in annular setting-out volute chamber lowermost end portion and stand in the anti-rotation adjustment rack, can prevent that the reaction force that produces when spraying titter water stirs from making the rotation of pump body, can adjust the anti-rotation fixedly fixture block of its submerged pump diving depth again.And be located at outside the volute chamber axial flow paddle of below, and can stir the sewage silt particle that the pump below deposits again, promptly simple in structurely play dual stirring action again.
The beneficial effects of the utility model are, owing to adopt left and right nozzle spray titter water agitation system and the axial flow paddle special construction of dual stirring in opposite directions, successfully solved the difficult problem that can both balancedly be pumped to high concentration mud sand sewage in the submerged pump operation overall process constantly.
