Description
Technical field
The utility model 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 by water-cooled parts cooling effect, electromagnetic load allowed to bear increases, and has improved the utilization ratio of material.But,, produce the winding local superheating then and burn because the generation water route of incrustation scale and sewage dirt stops up.Simultaneously, water swivel and each seal point place will cause short circuit and electric leakage dangerous owing to bear problem that hydraulic pressure leaks, and motor is easy to lose efficacy.
The model utility content
The purpose of this utility model provides the hydronic proof submersible sand discharging pump of a kind of employing inner sealing oil, this pollution discharge pump motor copper factor height, and materials consumption is few, high working efficiency.
The technical solution adopted in the utility model: 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, with the honeycomb duct of motor communicating with cooling cavity, described big impeller is fixed on the end of motor shaft, described motor cooling chamber communicates with coolship, be fixed with the plug cock lid in the described lower bearing room, formation one cavity that 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 described coolship.
Described small impeller is fixed on the motor shaft by flat key.
A kind of proof submersible sand discharging pump of the present utility model, 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, with the honeycomb duct of motor communicating with cooling cavity, described big impeller is fixed on the end of motor shaft, described motor cooling chamber communicates with coolship, be fixed with the plug cock lid in the described lower bearing room, formation one cavity that 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 described coolship.Adopt said structure, under the driving of small impeller, cold oil flows to honeycomb duct through the motor cooling chamber, flows to cavity again, finally gets back in the coolship, forms the oily circulating cooling system of an inner sealing, and the heat that the motor operation produces is taken out of with cold oil.So not only keep each advantage of water cycle cooling, and overcome the deficiency of water cycle cooling, had more high efficient cooling effect.The utility model is compared with other identical type of cooling motors of capacity, can raise the efficiency 10～15%.
Advantage of the present utility model: motor copper factor height, materials consumption are few, high working efficiency, good cooling results.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail:
Fig. 1 is a structural representation of the present utility model.
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, flat key, 11, the plug cock lid, 12, small impeller, 13, cavity.
Embodiment
As shown in Figure 1, 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, and form the plug cock cover 7 of coolship 5 between the lower bearing room 6, motor cooling chamber 8 and the honeycomb duct 9 that communicates with motor cooling chamber 8, described 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, formation one cavity 13 that 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 is fixed on the end of motor shaft 3 by flat key 10.
The utility model 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 motor 2 runnings are produced is taken out of with cold oil, 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)
