Description
Technical field
The utility model relates to pump industry machinery field, relates 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 with links in daily life simply in production, convenient.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 purpose of the utility model is to provide one kind directly to drive shaftless blade electric pump, should
Electric pump is small in size, and material consumption is few, and unpowered loss, work efficiency is high.
Realize the purpose of this utility model the technical solution adopted is that: this directly drive shaftless blade electric pump mainly include stator and
Rotor；The stator is made of blade pump case and the motor stator being immobilized in the shell；The rotor is by rotor
It is constituted with impeller, rotor is fixed on outside impeller and links together with impeller, and rotor directly drives impeller rotation: Gu
Two bearing shells being scheduled 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 utility model are: eliminating motor shaft and pump shaft since motor and vane pump height merge, taking
Disappeared the bearing of motor and vane pump, and rotor directly drives impeller rotation.So the shaftless blade electric pump and traditional electricity
Machine driving blade pump work compares the volume for reducing motor, blade pump assembly, has saved lot of materials, directly driving reduces
The energy loss of power train process, improves work efficiency, and changes the unit type of cooling, reduces unit noise；Rotor
It is all wrapped up by electric pump stator, electric pump No leakage.The present invention directly drives shaftless blade electric pump and can apply all original
Use the place of motor-driven vane pump unit.
Detailed description of the invention
Fig. 1 is the cross-section structure schematic diagram that the utility model directly drives shaftless blade electric pump.
Fig. 2 is the schematic cross-section for another structure that the utility model 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, the one of the conveying liquid medium that the utility model is a kind of vane pump and motor height is fused together
Kind directly drives shaftless blade electric pump.It mainly includes stator and rotor that this, which directly drives shaftless blade electric pump,；The stator is by blade pump case
Body 5 and the motor stator 1 being immobilized in the shell form；The rotor is made of rotor 2 and impeller 4, and rotor 2 is solid
It is scheduled on 4 outside of impeller and impeller 4 links together, rotor 2 directly drives the rotation of impeller 4；It is fixed in blade pump case 5
Two bearing shells 3 be located at 4 both ends of impeller support electric pump rotor, and in axially position electric pump rotor.1 He of motor stator
Rotor 2 carries out water-proofing treatment.The medium of the electric pump conveying is exported from impeller 4 to flow out, along motor stator 1 and electricity
Impeller is flowed back to by the gap of bearing shell 3 and impeller 4 in the gap of machine rotor 2, cooling to motor.The rotor of the electric pump is whole
It is wrapped up by electric pump stator, electric pump No leakage.This directly drives that shaftless blade pump structure is simple, and small in size, light-weight, material disappears
Consumption is few, and unpowered loss, work efficiency is high, and noise is small, can apply in all original fields using motor-driven vane pump unit
Institute.
