The utility model has the advantages that: (1) has adopted the axial air-gap inductor motor, it is directly assembled in the embedding pump case, its rotor and pump impeller are installed on the same arbor, and be sealed among the housing jointly, arbor is not exposed, thoroughly solved the leakage problem that is transferred flowing medium, reached and be transferred the technique effect that fluid does not have external leakage.(2) mode of stator and rotor being kept apart fully with separation layer has thoroughly solved internal leak and the adverse consequences of burning motor.(3) the utility model is compared with conventional pump, has saved coupling, has compact structure, and volume is little, number of spare parts is few, lightweight advantage.Under the condition with constant power, the utility model weight has only 30% of conventional pump, and its axial distance is short, and it is little to take up room, and has only 1/3 of conventional pump.(4) the utility model requires lowly in installation process to base and basis, does not have coupling centering problem, and it is an integral body that centrifugal pump and drive motor thereof are organically combined, more steady during operation, and the reliability height, vibration is little, noise is low.(5) the utility model is very convenient in the maintenance of pump, owing to adopted tray type structure, need not pump is pulled down from pipeline, only needs with the pump case both sides separately, and impeller partly can take out, and very convenient quick, the maintenance work amount is few, maintenance expenses is low.Simultaneously, do not leak, can under the condition of high vacuum degree situation, directly from vacuum tank, deliver to material in other containers owing to have.
Description of drawings:
Fig. 1 is the agent structure cross-sectional schematic of centrifugal pump described in the utility model.
Embodiment:
As shown in Figure 1, disc type centrifugal pump described in the utility model is made up of housing, motor and pump impeller.Wherein, housing is made up of the pump housing 2, bearing support 10 and end cap 14, and motor is a three-phase axial air-gap inductor motor, and pump impeller 3 is work done parts, and liquid produces pressure by its rotation and is pumped out the pump housing.The stator of motor is made up of iron core 12 and coil 11, be fixed in the end cap 14, in the inner chamber 17 of rotor 15 between bearing support 10 and end cap 14, be provided with the sealing isolation layer 16 that a usefulness non-magnet material is made between the interior edge face of bearing support 10 and end cap 14, the stator and the rotor of motor are isolated mutually; The iron core 12 of motor stator and coil 11 usefulness heat-conducting insulation materials 13 are filled and are enclosed between the end cap 14 and sealing isolation layer 16 of the pump housing, make and do not contain air in the stator cavity, help heat radiation on the one hand, can effectively protect coil 11 on the other hand.Rotor 15 is interfixed by coupling shaft 5 by the axis hole on epitrochanterian axis hole and the bearing support 10 with pump impeller 3, and is supported on the bearing support 10 by bearing pack 7; Bearing support 10 is installed between housing 2 and the end cap 14.Fastening between coupling shaft 5 and the pump impeller 3 with clamping bolt 20, also can adopt the key connection to wait other Placement to fix.Between the coupling shaft 5 of pump impeller 3 and the axis hole of bearing support 10 black box 18 is installed, and between the axis hole on coupling shaft 5 and the bearing support 10, be provided with seal ring 6 in a side that is positioned at pump chamber 8, be provided with seal ring 19 in a side that is positioned at inner chamber 17, with stuffing box bearing group 7.The sealing of bearing pack 7, black box 18 can be according to the difference of fed sheet of a media, according to the characteristic that is transferred medium, adopt the seal ring and the seal ring of unlike material,, the medium in the pump chamber 8 can not flow in the inner chamber 17 so that seal ring 6 and seal ring 19 can not be corroded.The separation layer of making of non-magnet material between rotor 15 and the stator 16 is kept apart rotor 15 and stator fully, has avoided being transferred the internal leak problem of medium, has stopped the adverse consequences that motor burns out because of seepage.The on-the-spot installation of the utility model is also very convenient, goes up as long as pump housing seat 1 is fixed on the basis.
