Abstract
The utility model discloses a novel integral electric pump comprising a housing. The integral electric pump is characterized in that a stator winding is inlaid on the housing; a rotor and the rotating part of the pump are made into one rotating component; the rotor in the rotating component is fixed with permanent magnetic material at the position opposite to the stator winding; a nonmagnetic distance sleeve is arranged between the stator winding and the permanent magnetic material of the rotor. The utility model has the advantages that the pump and the motor are combined into integration and of compact structure, small size, no need for dynamic seal, and high reliability.
Description
The utility model relates to liquor pump, is a kind of vane type oil pump, is a kind of pumping installations furtherly, specifically, is a kind of electrically driven (operated), unit of comprising pump and its drive unit.
Connect general total need movable sealing on the power transmission shaft of pump with shaft coupling or other drive disk assemblies between tradition electric pump general motor and the pump.Though and magnetic drive pump need not movable sealing, structure is complicated, though immersible pump structural entityization, volume are little, seal request height, especially movable sealing require than higher.
The purpose of this utility model provide a kind of with pump and motor unite two into one, compact conformation, in light weight, novel overall formula electric pump that reliability is high.
Technical solution of the present utility model is: a kind of novel overall formula electric pump, comprise shell, the difference of itself and prior art is: be inlaid with stator winding on shell, the rotating part of rotor and pump is made same rotatable parts, the relative position with stator winding of rotor in the rotatable parts is fixed with permanent magnetic material (or general permeability magnetic material), and a non-magnetic conduction spacer is arranged between stator winding and rotor permanent magnetic material.
Rotatable parts described in the utility model are loaded in the sliding bearing at shell middle part.Certainly, also can adopt other suitable versions.
Water inlet on the shell described in the utility model is positioned at the shell front end, and delivery port is positioned at the shell front side face.Certainly, also can adopt other suitable entery and delivery port positional structures.
In the rotatable parts described in the utility model, and with housing that rotor place cavity links to each other in have the cooling duct.Certainly, also can adopt other suitable cooling structure forms or under suitable situation, without the cooling duct.
The utility model has the advantages that: pump and motor are united two into one, compact conformation, volume are little, in light weight, greatly reduce the manufacturing cost of electric pump, and have simplified the structure of electric pump, save movable sealing, shaft coupling, electric motor fan etc., helped improving the efficient of electric pump.And applied widely, be with a wide range of applications.The reliability height, non-failure operation time is long.
The utility model is described in further detail below in conjunction with drawings and Examples:
Accompanying drawing is the structural representation of a kind of novel overall formula electric pump of the present utility model.
Accompanying drawing has been described an embodiment of the present utility model.In a middle casing 11, sliding bearing 12 is housed, axle 14 is housed in the sliding bearing 12, axle 14 front ends are equipped with impeller 1, rotor 6 is equipped with at axle 14 rear portions, rotor 6 surfaces are fixed with permanent magnetic material (or general permeability magnetic material) 7, front end at middle casing 11 is equipped with front end housing 13, middle casing 11 opposite sides are fixed with back casing 4, be inlaid with stator winding 3 in the back casing 4, the spacer 2 that has a non-magnet material to make between the permanent magnetic material on stator winding 3 and the rotor 6, back casing 4 opposite sides are equipped with bonnet 5.Water inlet 9 is positioned at the centre of front end housing 13, and delivery port 10 is positioned at the avris of front end housing 13, has cooling duct 8 in axle 14 and middle casing 11, comes the cooling motor rotor with pumped (conveying) medium.In fact this electric pump can be used as diving, suction dual-purpose pump, and the electric pump cooling problem when sealing problem during diving and suction (non-diving) has all obtained good solution.
