Abstract
The utility model relates to a kind of self-priming mud sealed type canned motorpump, comprises pump, motor and heat exchanger composition, and wherein pump is made up of the pump housing and impeller; Motor comprises stator and rotor, and stator and rotor exterior are respectively arranged with stator can, Rotor can, and described motor lower end is provided with support and base; Between the described pump housing and motor, be connected by connecting body; Whole motor is divided into upper and lower two-part by bearing, and one section of bearing is connected with the pump housing, and the other end is connected with heat exchanger; Described pair of impeller is arranged on by rotor.The beneficial effects of the utility model, can realize shielded electric-pump and have the feature without leakage, hermetically sealed structure, and shielded electric-pump does not need external lubrication simultaneously, and compact structure, can carry the liquid of sneaking on a small quantity mud.
Description
Technical field
The utility model relates to canned motorpump field, refers to specifically a kind of with canned motorpump self-absorption function, that can carry a small amount of mud liquid.
Background technique
At present, self-priming shielded electric-pump, adopts gas-liquid mixed self-priming pump working principle mostly, a certain amount of liquid need prestore before startup in the pump housing, pump up the turning effort due to impeller after moving, air and the liquid of suction line fully mix, and are discharged to air-water separation chamber.The gas on gas-liquid separation chamber top is overflowed, and the liquid of bottom returns to impeller, again mixes with the residual gas of suction line, until the gas in pump and feed liquor pipeline is all drained, completes self-priming, and normal extracting liquid; Shortcoming is due to needs fed sheet of a media lubrication motor bearing, so can not carry the liquid of sneaking into a small amount of mud.And mud sealed type canned motorpump, by install mechanical seal device and motor cavity liquid-circulating cooling system independently additional between the pump housing and motor, thereby prevent that the liquid of sneaking into a small amount of mud from entering motor cavity, finally realize canned motorpump and can carry the liquid of sneaking into a small amount of mud; But but can not realize self-absorption function.
Summary of the invention
The technical problems to be solved in the utility model is, for the defect of prior art existence, provides a kind of self-priming mud sealed type canned motorpump.
A kind of self-priming mud sealed type canned motorpump, comprises pump, motor and heat exchanger composition, and wherein said pump is made up of the pump housing and impeller; Described motor comprises stator and rotor, and stator and rotor exterior are respectively arranged with stator can, Rotor can, and described motor lower end is provided with support and base; Between the described pump housing and motor, be connected by connecting body; Whole motor is divided into upper and lower two-part by bearing, and bearing is positioned at bearing support, and one section of bearing is connected with the pump housing, and the other end is connected with heat exchanger, and bearing outside is connected to axle sleeve, and described axle sleeve can relatively rotate; Described pair of impeller is arranged on by rotor.
In the utility model, described mechanical seal is arranged on the axis of elongation of rotor axis of electric.
In the utility model, between described heat exchanger and bearing, be connected by support, described heat exchanger top is provided with outlet valve and pressure gauge.
In the utility model, described bearing is also connected with thrust disc.
The utility model beneficial effect: the technical solution of the utility model, can realize shielded electric-pump and there is the feature without leakage, hermetically sealed structure, shielded electric-pump does not need external lubrication simultaneously, and compact structure, can carry the liquid of sneaking on a small quantity mud.
