Abstract
A mining explosion-proof water-cooling submersible sewage pump is provided, which comprises an upper cover, a motor, a motor stand, a motor shell and a snail shell and is characterized in that: outside the motor is provided with a cycling water-cooling device which comprises a water jacket shell arranged outside the motor shell. Among the water shell, the motor shell, the motor stand and the upper cover form the water jacket for containing cooling water. On the snail shell is provided with a water inlet hole and a water outlet hole of cooling water running through the motor stand for communicating the water jacket. The utility model transfers the heat elimination of the motor from the water-cooling radiation through natural dipping to compulsory cycling water-cooling radiation. When the motor is exposed to the air, the submersible sewage pump can work normally. Extracting out the sewage, the motor will not be too hot.
Description
Technical field:
The utility model relates to a kind of water pump, particularly relates to the flame-proof type immersed sewage electric pump that uses under a kind of mine.
Background technique:
At present, the flame-proof type immersed sewage electric pump that mine uses is down formed by parts such as base, motor, motor cabinet, motor casing, loam cake, impeller and spiral cases, and spiral case is fixed on the base, is motor cabinet on the spiral case, motor casing and loam cake with motor seal on motor cabinet.The immersed sewage electric pump is under water during work, and the heat that motor produces is dispersed in the water naturally by motor casing.This immersed sewage electric pump is owing to must soak work in water; therefore; sewage can't exhaust; exhausted soon at water, when the immersed sewage electric pump exposes from sewage; just must in time shut down, otherwise the time that the motor of immersed sewage electric pump turns round in air is long slightly; motor will burn because of overheated, causes the certain economic loss.
Summary of the invention:
The purpose of this utility model is to change the deficiencies in the prior art, designs a kind of circulating water cooling, sewage can be taken out most flame-proof mine water-cooled immersed sewage electric pump.
The realization the technical solution of the utility model is, a kind of flame-proof mine water-cooled immersed sewage electric pump comprises loam cake, motor, motor cabinet, motor casing and spiral case, and feature is that the outer periphery of motor casing is equipped with water-circulating cooling device.
The utility model is owing to be provided with the pump circulation water cooling plant in the periphery of motor casing, therefore, the heat radiation of motor becomes enforceable circulating water cooling heat radiation by the water-cooling of natural immersion, not only radiating condition is greatly improved, what is more important exhausts soon at water, when motor exposes in air, but immersed sewage electric pump proper functioning still, by the water-circulating cooling device cooling motor, guarantee that motor can be not overheated, exhaust, realize the purpose of this utility model until sewage.
Description of drawings:
Accompanying drawing is a structural representation of the present utility model.
Embodiment:
The motor casing 2 peripheral water-circulating cooling devices that are provided with of the present utility model comprise the water jacket shell 3 that is arranged on outside the motor casing 2, sealing is affixed between water jacket shell 3 and motor cabinet 8, the loam cake 9, forms the water jacket hold cooling water between water jacket shell 3 and motor casing 2, motor cabinet 8, the loam cake 9; Spiral case 5 is fixed on the base 6, and spiral case 5 has the water inlet 4 that is communicated with the cooling water of water jacket by motor cabinet 8 near the top of outlet pipe, and spiral case 5 has the osculum 7 that is communicated with the cooling water of water jacket by motor cabinet 8 away from the top of outlet pipe; The diameter of water inlet is generally 4～10 millimeters, and the diameter of osculum is not less than the diameter of water inlet.During work, when the impellers of rotation go out water pump in the spiral case 5, also water 4 is squeezed into water jacket from the water inlet, cooling motor 1 is because of the hydraulic pressure at 4 places, the water inlet hydraulic pressure greater than osculum 7 places, therefore, cooling water is under the drive of impeller, and automatic cycle reaches the purpose of cooling motor 1.The utility model is simple in structure, and is respond well, in actual the use, can reduce rate of fault, the spoilage of immersed sewage electric pump greatly, improves the serviceability rate and the using effect of equipment.
