Description
Technical field
The present invention relates to pump industry machinery fields, relate in particular to one kind and directly drive shaftless blade electric pump.
Background technique
With the development of the mankind, scientific and technical progress, new engineering goods constantly change people's lives, motor band
The birth of dynamic delivery pump, let us become simple, conveniently with links in daily life in production.But it applies at present
Electric pump is made of two units of vane pump and motor.The power of motor is transferred to motor shaft by rotor, then by shaft coupling
It is transferred to pump shaft, drives the impeller rotary work of vane pump；Or the power of motor is transferred to motor shaft by rotor, drives
It is mounted on the impeller rotary work of motor shaft blade pump.Pump structure form and transmission mode described above, can only pass through electricity
Machine output shaft delivers power to pump shaft, can just make pump work.Due to the transmission and work using axis, the volume of electric pump is caused
Greatly, high material consumption, power energy loss in transmission process is big, and working efficiency is low.
Summary of the invention
In order to solve the deficiencies in the prior art, the object of the present invention is to provide one kind directly to drive shaftless blade electric pump, the electric pump
Small in size, material consumption is few, and unpowered loss, work efficiency is high.
Achieve the object of the present invention the technical solution adopted is that: this directly drive shaftless blade electric pump mainly include stator and turn
Son；The stator is made of blade pump case and the motor stator being immobilized in the shell；The rotor by rotor and
Impeller is constituted, and rotor is fixed on outside impeller and links together with impeller, and rotor directly drives impeller rotation；It is fixed
Two bearing shells in blade pump case are located at impeller both ends support electric pump rotor, and in axially position electric pump rotor.
The motor stator and rotor carries out water-proofing treatment.
The medium of the electric pump conveying is flowed out from impeller outlet, along the gap of motor stator and rotor, is passed through
Impeller is flowed back in the gap of bearing shell and impeller, cooling to motor.
The rotor of the electric pump is all wrapped up by electric pump stator, electric pump No leakage.
The beneficial effects of the present invention are: eliminating motor shaft and pump shaft since motor and vane pump height merge, eliminating
The bearing of motor and vane pump, rotor directly drive impeller rotation.So the shaftless blade electric pump and traditional motor drive
Movable vane piece pump work compares the volume for reducing motor, blade pump assembly, has saved lot of materials, directly driving reduces power
The energy loss of transmission process, improves work efficiency, and changes the unit type of cooling, reduces unit noise；Rotor is whole
It is wrapped up by electric pump stator, electric pump No leakage.The present invention directly drives shaftless blade electric pump and can apply in all original uses
The place of motor-driven vane pump unit.
Detailed description of the invention
Fig. 1 is the cross-section structure schematic diagram that the present invention directly drives shaftless blade electric pump.
Fig. 2 is the schematic cross-section for another structure that the present invention directly drives shaftless blade electric pump.
In figure, 1, motor stator, 2, rotor, 3, bearing shell, 4, impeller, 5, shell.
Specific embodiment
In the accompanying drawings, a kind of one kind for the conveying liquid medium that the present invention is vane pump and motor height is fused together is straight
Drive shaftless blade electric pump.It mainly includes stator and rotor that this, which directly drives shaftless blade electric pump,；The stator is by 5 He of blade pump case
The motor stator 1 being immobilized in the shell forms；The rotor is made of rotor 2 and impeller 4, and rotor 2 is fixed on
4 outside of impeller and impeller 4 link together, and rotor 2 directly drives the rotation of impeller 4；Two be fixed in blade pump case 5
A bearing shell 3 is located at 4 both ends of impeller support electric pump rotor, and in axially position electric pump rotor.The motor stator 1 and motor
Rotor 2 carries out water-proofing treatment.The medium of the electric pump conveying is exported from impeller 4 to flow out, and turns along motor stator 1 and motor
The gap of son 2, flows back to impeller by the gap of bearing shell 3 and impeller 4, cooling to motor.The rotor of the electric pump is all electric
Pump stator wraps up, electric pump No leakage.It is simple that this directly drives shaftless blade pump structure, small in size, light-weight, material consumption
Few, unpowered loss, work efficiency is high, and noise is small, can apply in all original places using motor-driven vane pump unit.
