Abstract
The invention relates to a submersible sewage pump which comprises a pump body, a motor, a motor shaft, a large impeller, a cooling disc, a lower bearing chamber, an oil plug shield, a motor cooling cavity and a flow guide pipe, wherein the cooling disc is formed between the lower bearing chamber and the oil plug shield; and the flow guide pipe is communicated with the motor cooling cavity; the large impeller is fixed at the end part of the motor shaft; the motor cooling cavity is communicated with the cooling disc; an oil plug cover is fixed on the lower bearing chamber; a cavity communicated with the cooling disc is formed between the oil plug cover and the oil plug shield and is communicated with the flow guide pipe; a small impeller is arranged in the cooking disc and comprises a hub and a plurality of blades, wherein the hub is fixed with the motor shaft; and the blades are uniformly fixed on the hub. The submersible sewage pump has the advantages of high motor tank full rate, less material consumption, high work efficiency and good cooling effect.
Description
Technical field
The present invention relates to a kind of proof submersible sand discharging pump.
Background technique
Present domestic proof submersible sand discharging pump staor winding adopts water-cooled quite general.The specific heat of liquid, thermal conductivity ratio gas is big, so the heat dissipation potential of water-cooled greatly improves.Remarkable through water-cooled parts cooling effect, electromagnetic load allowed to bear increases, and has improved the utilization ratio of material.But, because the obstruction of the generation water route of incrustation scale and sewage dirt, produce the winding local superheating then and burn.Simultaneously, water swivel and each seal point place will cause short circuit and electric leakage dangerous owing to bear the problem that hydraulic pressure leaks, and motor is easy to lose efficacy.
Summary of the invention
The purpose of this invention is to provide the hydronic proof submersible sand discharging pump of a kind of employing inner sealing oil, this pollution discharge pump motor copper factor is high, and materials consumption is few, high working efficiency.
The technological scheme that the present invention adopts: a kind of proof submersible sand discharging pump; Comprise the plug cock cover that forms coolship between the pump housing, motor, motor shaft, big impeller, coolship, lower bearing room and the lower bearing room, motor cooling chamber and with the honeycomb duct of motor communicating with cooling cavity; Said big impeller is fixed on the end of motor shaft, and said motor cooling chamber communicates with coolship, is fixed with the plug cock lid in the said lower bearing room; The cavity that formation one communicates with coolship between this plug cock lid and the plug cock cover; This cavity communicates with honeycomb duct, is provided with small impeller in the said coolship, and said small impeller comprises wheel hub and a plurality of blade; Said wheel hub and motor shaft are fixed, and said a plurality of blades are fixed on the wheel hub equably.
Said blade is arc-shaped structure.
Advantage of the present invention: the motor copper factor is high, materials consumption is few, high working efficiency, good cooling results.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the present invention is done further detailed explanation:
Fig. 1 is a structural representation of the present invention.
Fig. 2 is a small impeller structural representation of the present invention.
Wherein: 1, the pump housing, 2, motor, 3, motor shaft, 4, big impeller, 5, coolship, 6, lower bearing room, 7, the plug cock cover, 8, the motor cooling chamber, 9, honeycomb duct, 10, wheel hub, 11, the plug cock lid, 12, small impeller, 13, cavity, 14, blade.
Embodiment
As depicted in figs. 1 and 2; A kind of proof submersible sand discharging pump, the pump housing 1, motor 2, motor shaft 3, big impeller 4, coolship 5, lower bearing room 6, with lower bearing room 6 between plug cock cover 7, motor cooling chamber 8 and the honeycomb duct 9 that communicates with motor cooling chamber 8 of formation coolship 5, said big impeller 4 is fixed on the end of motor shaft 3; Motor cooling chamber 8 communicates with coolship 5; Be fixed with plug cock lid 11 in the lower bearing room 6, the cavity 13 that formation one communicates with coolship 5 between this plug cock lid 11 and the plug cock cover 7, this cavity 13 communicates with honeycomb duct 9; Be provided with small impeller 12 in the coolship 5; This small impeller 12 comprises wheel hub 10 and a plurality of blades 14, and wheel hub 10 is fixing with motor shaft 3, and a plurality of blades 14 are fixed on the wheel hub 10 equably; In order to improve the working efficiency of small impeller 12, blade 14 is designed to convex structure.
The present invention is running like this: proof submersible sand discharging pump is in work; Motor 2 also drives small impeller 12 and rotates when driving big impeller 4 rotations; Cold oil in the small impeller 12 rotating drive coolships 5 flows in the motor cooling chamber 8; The heat that produces motor 2 runnings is taken out of with cold oil, and cold oil arrives cavity 13 through honeycomb duct 9, flow back into again in the coolship 5 at last.Circuit cools off successively, reaches the effect of efficient cooling.
Claims (2)
1. proof submersible sand discharging pump, comprise the plug cock cover that forms coolship between the pump housing, motor, motor shaft, big impeller, coolship, lower bearing room and the lower bearing room, motor cooling chamber and with the honeycomb duct of motor communicating with cooling cavity, said big impeller is fixed on the end of motor shaft; Said motor cooling chamber communicates with coolship; Be fixed with plug cock lid in the said lower bearing room, the cavity that formation one communicates with coolship between this plug cock lid and the plug cock cover, this cavity communicates with honeycomb duct; Be provided with small impeller in the said coolship; It is characterized in that said small impeller comprises wheel hub and a plurality of blade, said wheel hub and motor shaft are fixed, and said a plurality of blades are fixed on the wheel hub equably.
