Description
Technical Field
The utility model relates to a pump industry machinery, specifically speaking relate to a shaftless blade charge pump.
Background
With the development of human beings and the progress of science and technology, the life of people is constantly changed to new mechanical products, and the birth of the delivery pump is driven by the motor, so that each link of people in production and daily life becomes simple and convenient. However, the electric pump currently used is composed of two units, a vane pump and a motor. The power of the motor is transmitted to a motor shaft by a motor rotor and then transmitted to a pump shaft by a coupling to drive an impeller of the vane pump to rotate; or the power of the motor is transmitted to the motor shaft by the motor rotor to drive the impeller of the vane pump arranged on the motor shaft to rotate and work. The electric pump has the advantages that the structure form and the transmission mode of the electric pump can only enable the pump to work by transmitting power to the pump shaft through the output shaft of the motor. The electric pump has large volume, high material consumption, high energy loss of power in the transmission process and low working efficiency due to the transmission and the work of the shaft.
Disclosure of Invention
In order to solve the defects of the prior art, the utility model aims to provide a shaftless blade electric pump, this electric pump is small, and material consumption is few, and no power loss, work efficiency is high.
Realize the utility model discloses a technical scheme that the purpose adopted is: the shaftless blade electric pump mainly comprises a stator and a rotor; the stator consists of a vane pump shell and a motor stator fixed in the shell; the rotor consists of a motor rotor, a rotor connecting disc and an impeller, the motor rotor is fixed at the outer end of the rotor connecting disc, the rotor connecting disc is fixedly connected with the impeller, and the motor rotor drives the connecting disc and the impeller to rotate at a high speed; two bearing bushes supporting the electric pump rotor for rotation are fixed close to the centre line of the vane pump housing and axially position the electric pump rotor.
And the motor stator and the motor rotor are subjected to waterproof treatment.
The medium conveyed by the electric pump flows to the gap between the motor stator and the motor rotor along the gap of the bearing bush to perform self-cooling on the motor.
The utility model has the advantages that: because the motor and the vane pump are highly fused, a motor shaft and a pump shaft are eliminated, bearings of the motor and the vane pump are eliminated, and a motor rotor directly drives the impeller to rotate. Compared with the traditional motor-driven vane pump, the electric pump without the shaft vanes has the advantages that the sizes of the motor and the vane pump unit are reduced, a large amount of materials are saved, the energy loss in the power transmission process is reduced through direct driving, the working efficiency is improved, the cooling mode of the unit is changed, and the noise of the unit is reduced. The electric pump without the shaft blade can be applied to all places where motor blade pump units are originally used.

Fig. 1 is a schematic diagram of a cross-sectional structure of the electric pump without axial blades of the present invention.
In the figure, the motor comprises a motor stator 1, a motor rotor 2, a motor rotor 3, a connecting disc 4, an impeller 5, a bearing bush 6 and a shell.
Detailed Description
In the attached drawings, the shaftless blade electric pump mainly comprises a stator and a rotor; the stator consists of a vane pump shell 6 and a motor stator 1 fixed in the shell 6; the rotor consists of a motor rotor 2, a rotor connecting disc 3 and an impeller 4, the motor rotor 2 is fixed at the outer end of the rotor connecting disc 3, the rotor connecting disc 3 and the impeller 4 are fixedly connected together, and the motor rotor 2 drives the connecting disc 3 and the impeller 4 to rotate at a high speed; two bearing bushes 5 supporting the electric pump rotor in rotation are fixed close to the centre line of the vane pump housing 6 and axially position the electric pump rotor. And the motor stator 1 and the motor rotor 2 are both subjected to waterproof treatment. The medium conveyed by the electric pump flows to the gap between the motor stator 1 and the motor rotor 2 along the gap of the bearing bush 5 to perform self-cooling on the motor. And the bearing bush 5 realizes self-lubrication by a medium conveyed by an electric pump. The shaftless vane electric pump has the advantages of simple structure, small volume, light weight, less material consumption, no power loss, high working efficiency and low noise, and can be applied to all places where motor vane pump units are originally used.
