In order to solve the above-mentioned technical problem, it is pumped in a kind of Modularized pipe of the utility model, including pump motor, the pump electricity It is provided with motor cover and motor casing outside machine, forms water stream channel, the connection of motor casing end between the motor cover and motor casing There is impeller housing, be fixed with two or more impeller assembly in the impeller housing side by side, the impeller assembly is by guide wheel And the impeller composition in guide wheel, the pump motor are connect by motor shaft with impeller.

Have the fixed linking arm of the impeller assembly on the impeller housing, which extends to the electricity Casing is simultaneously connected and fixed by screw and motor casing.

The pump motor includes stator seat, and the rotor with the motor axis connection is provided on the outside of the stator seat, described fixed Exciting Windings for Transverse Differential Protection is installed in the middle part of stroma, there is the long axis hole for installing motor shaft in stator seat, described motor casing one end with it is fixed Stroma is connected and fixed, and the other end is equipped with connecting seat, and it is logical that the first, second flow is respectively provided on the stator seat and impeller housing Road junction.

The long axis hole both ends are separately installed with the first, second bearing for supporting the motor shaft.

There is cable channel, the cable channel one end to lead to the Exciting Windings for Transverse Differential Protection, cable channel is another in the stator seat It holds exposed.

The utility model has the beneficial effects that：Pump passes through impeller housing by impeller assembly and pump motor in this Modularized pipe Connection, it is not necessary that water pump outer barrel is arranged, simplifies product structure, assembling product is easier, and advantageously reduces production cost, and subtract Small small product size and weight, are easy to carry about with one.

Description of the drawings

Utility model will be further described in detail below with reference to the attached drawings and specific embodiments.

Fig. 1 is the structural schematic diagram of the utility model；

Fig. 2 is the schematic cross-sectional view of the utility model.

Specific implementation mode

Referring to Fig.1, Fig. 2 is pumped in a kind of Modularized pipe of the utility model, including pump motor 1, outside the pump motor 1 It is provided with motor cover 3 and motor casing 4, forms water stream channel 5, the connection of 4 end of motor casing between the motor cover 3 and motor casing 4 Have impeller housing 6, be fixed with two or more impeller assembly 2 in the impeller housing 6 side by side, the impeller assembly 2 by Impeller 22 in guide wheel 21 and guide wheel 21 forms, and the pump motor 1 is connect by motor shaft 11 with impeller 22.This modularization Impeller assembly is connect by pump by impeller housing with pump motor in pipe, it is not necessary that water pump outer barrel is arranged, simplifies product structure, product Assembling is easier, and is advantageously reduced production cost, and reduce small product size and weight, is easy to carry about with one.

Wherein, have 2 fixed linking arm 7 of the impeller assembly on the impeller housing 6, which prolongs It extends to the motor casing 4 and is connected and fixed by screw and motor casing 4, make to connect between each module and more stablize.

The pump motor 1 includes stator seat 12, which is provided with the rotor being connect with the motor shaft 11 13,12 middle part of the stator seat is equipped with Exciting Windings for Transverse Differential Protection 14, has the long axis hole 15 for installing motor shaft, institute in stator seat 12 It states 4 one end of motor casing to be connected and fixed with stator seat 12, the other end is equipped with connecting seat 8, on the stator seat 12 and impeller housing 6 It is respectively provided with the first, second water stream channel mouth 9,10.Outer-rotor structure is used in pump motor, makes motor that there is high torque and good Good heat dissipation effect, and water stream channel is formed between motor casing and motor cover, allow motor directly as pump line body one in pipe Part is not necessarily to additionally mounted tube body, can simplify pump configuration in pipe, reduces production cost.

15 both ends of long axis hole are separately installed with the first, second bearing 16,12 for supporting the motor shaft 11, make Electric machine structure is more stablized.There is in the stator seat 12 cable channel 18,18 one end of cable channel lead to the excitation around Group 14,18 other end of cable channel is exposed, and electric wire is easier to install and safeguard across cable channel.
