Description

Sludge-type chemical industry shielded electric-pump
Technical field:
The utility model relates to fluid conveying machine, relates in particular to pump, particularly a kind of sludge-type chemical industry shielded electric-pump.
Background technique:
In the prior art, the medium that the motor in the shielded electric-pump utilizes pump to carry cools off with lubricated.Under conventional operating mode, general operation medium can meet the demands.But when slurry conveyed type medium or have the medium of particle, owing to have solid in the medium, can produce grinding to graphite sliding bearing, thereby reduce the working life of graphite bearing, cause motor shortening in working life, therefore fault is frequent, and common shielded electric-pump is not suitable for slurry conveyed type medium or has the medium of particle.
Summary of the invention:
The purpose of this utility model provides a kind of sludge-type chemical industry shielded electric-pump, and described this sludge-type chemical industry shielded electric-pump will solve the technical problem that shielded electric-pump in the prior art is not suitable for slurry conveyed type medium or has the medium of particle.
This sludge-type chemical industry shielded electric-pump of the present utility model is made of pump and motor, described pump is made of the pump housing and pump cover, described motor is by casing, stator, rotor and rotating shaft constitute, described stator is fixed in the casing, described rotor is fixedly installed in the rotating shaft, described rotating shaft is arranged in the casing by bearing and is positioned on the shaft axis of stator, the front end of described casing is fixedlyed connected with described pump cover, described rotating shaft is passed pump cover and is extended in the pump housing, be provided with impeller in the described pump housing, described impeller is fixedly installed in the rotating shaft, wherein, be provided with dividing busing between the front end of described casing and the pump cover, dividing busing is passed in described rotating shaft, be provided with circulation impeller in the front end inner chamber of the casing of dividing busing rear side, described circulation impeller is fixedly installed in the described rotating shaft, the outside of described casing is set with a cooler, described cooler is provided with cooling water intake and coolant outlet, be provided with circulating line in the described cooler, one end of described circulating line is communicated with the front end inner chamber of casing, the other end of described circulating line is communicated with the rear end inner chamber of casing, the front end inner chamber of described casing is communicated with the rear end inner chamber, the rear end of described casing is provided with a fluid infusion mouth, and described fluid infusion mouth is communicated with the rear end inner chamber of casing.
Further, described cooler is fixedly attached to the outside of described casing.
Further, be provided with Sealing between the front end inner chamber of described casing and stator and the rotor, be provided with Sealing between the rear end inner chamber of described casing and stator and the rotor.
Working procedure of the present utility model is such, and the pump housing, impeller, pump cover are formed the pump part, slurry conveyed type medium or have the medium of particle, and the cooling-lubricant of shield electric machine adopts the liquid part in institute's fed sheet of a media, does not contain mud or solid.The cooling-lubricant of shield electric machine divides formation independent circulation by cooler in motor section under the differential pressure action that circulation impeller produces.The medium of dividing busing limit transport enters shield electric machine, by the fluid infusion mouth cooling-lubricant is replenished, and can prevent that the concentration of medium of carrying from descending, and reduces the consumption of media fluid part simultaneously.Additional cooling-lubricant can utilize small-sized metering pump or high-order liquid container to carry out.The heat that shield electric machine is in operation and produces is cooled off by cooler by cooling-lubricant.
The utility model and prior art contrast, and its effect is positive and tangible.The utility model is by being provided with dividing busing between motor casing and pump cover, prevent that solid matter from entering in the motor, by circulating line and the cooler that is arranged on the motor casing shield electric machine is cooled off simultaneously, can satisfy slurry conveyed or have the working condition requirement of granule medium, simple in structure, effect is remarkable.
