Description
Technical field
The described nothing of the utility model is stopped up canned motorpump and is related to a kind of canned motorpump, and particularly a kind of being applicable to carries the nothing that contains large particle solid matter, long fibre, high gas content, high viscosity medium to stop up canned motorpump.
Background technique
At present; Conveying contains the pump of large particle solid matter, long fibre, high gas content, high viscosity medium; All adopt common nothing to stop up chemical flow-process pump, unavoidably have leakage problem, just have any problem for danger medium such as carrying severe toxicity; And existing canned motorpump decapacitation is carried outside the cleaning medium, can only carry the medium that contains a small amount of fine particle.And for carrying the pump that contains large particle solid matter, long fibre, high gas content, high viscosity medium also not have.To existing problem in the above-mentioned existing technology, a kind of novel nothing of research and design is stopped up canned motorpump, and existing problem is very necessary in the existing technology thereby overcome.
Summary of the invention
In view of existing problem in the above-mentioned existing technology; The purpose of the utility model is that a kind of novel nothing of research and design is stopped up canned motorpump; Can only carry cleaning medium, can only carry the medium that contains a small amount of fine particle thereby solve existing canned motorpump, and can not carry problems such as containing larger particles solid matter, long fibre, high gas content, high viscosity medium.
The described nothing of the utility model is stopped up canned motorpump and is made up of pump, connecting body, shield electric machine, heat exchanger.Described pump is made up of the pump housing and impeller.The impeller that is provided with in the pump housing chamber is not for there being the rotary flow type of obstruction impeller.Described pump is connected by connecting body with shield electric machine, and described shield electric machine is made up of stator and rotor, and rotor is supported by the fore bearing that is contained in the rear bearing on the shield electric machine rear end cover and be contained on the connecting body.The axle of described rotor is deep in the pump housing through connecting body.Between the rotor shaft of described connecting body and shield electric machine mechanical seal is housed, pump chamber and shield electric machine chamber are separated.On the described rotor shaft sub-propeller is housed, rotor shaft has radial hole at the sub-propeller place, and spindle nose has the center deep hole behind the rotor shaft, and the radial hole of rotor shaft communicates with the center deep hole.Rotor rear axle hook bolt has center hole.Described rear end cover afterbody connects the fluid injection flange, and the fluid injection flange connects heat exchanger, and the other end of heat exchanger is connected to the through hole that connecting body and shield electric machine joint are offered.
The purpose that the described nothing of the utility model is stopped up canned motorpump the utility model provides a kind of nothing obstruction canned motorpump, is used for not having fully carrying containing large particle solid matter, long fibre, high gas content, high viscosity medium with leaking, overcomes the deficiency of existing technology.
The described nothing of the utility model is stopped up canned motorpump, is applicable to carry the nothing that contains large particle solid matter, long fibre, high gas content, high viscosity medium to stop up canned motorpump.Form by pump, shield electric machine, heat exchanger.Said pump partly comprises the pump housing and rotary flow type impeller; Said shield electric machine comprises stator and rotor, and rotor is by being contained in the bearing on the rear end cover and being contained in the bearings on the connecting body; Said heat exchanger is connected between connecting body and the rear end cover.Pump is connected by connecting body with shield electric machine; Mechanical seal is housed in connecting body; Pump chamber and shield electric machine chamber are separated; Be provided with the fluid injection flange at the rear end cover afterbody; In the shield electric machine chamber, inject the cooling and lubricating medium that cleans,
avoided fed sheet of a media to get in the shield electric machine chamber, protected bearing.Cooling and lubricating medium in the shield electric machine chamber is played circulation by being contained in epitrochanterian sub-propeller, and motor cools off through heat exchanger the temperature rise that the cooling and lubricating medium produces, and guarantees that the cooling and lubricating medium temperature is in the scope that motor allows.Thereby realize carrying and contain large particle solid matter, long fibre, high gas content, high viscosity medium.
The nothing of the utility model is stopped up canned motorpump, owing to mechanical seal is housed at the connecting body place, and the pressure in the shield electric machine chamber is greater than pump inlet pressure, so fed sheet of a media can not get in the shield electric machine chamber.During work, fed sheet of a media is got into by the pump housing, after the impeller pressurization, is discharged by pump housing outlet.The cooling circulation liquid of motor and bearing injects motor cavity by the fluid injection flange; Its circulation distance is: spindle nose center hole → rotor shaft cavity of spindle nose behind the crack between crack → fore bearing and the axle sleeve → be connected body opening → heat exchanger → rear end cover and rotor between sub-propeller place radial hole → sub-propeller → stator can and Rotor can behind the cavity → rear axle hook bolt center hole → rotor shaft of spindle nose behind rear end cover and the rotor forms a circulation; Also have sub-fraction to get back to the cavity of spindle nose behind rear end cover and the rotor from the medium of sub-propeller output, form a circulation through crack between rear bearing and the axle sleeve.These two circulations have guaranteed lubricating the cooling of motor and bearing.
The nothing of the utility model is stopped up the beneficial effect of canned motorpump: can prevent that fed sheet of a media from getting into motor cavity, effectively protect bearing, realize not having fully the conveying of leakage ground and contained large particle solid matter, long fibre, high gas content, high viscosity medium.
