Description
Technical field
The present invention relates to pump industry machinery fields, relate in particular to a kind of 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 object of the present invention is to provide a kind of shaftless blade electric pump, the electric pump volumes
Small, material consumption is few, and unpowered loss, work efficiency is high.
Achieve the object of the present invention the technical solution adopted is that: the shaftless blade electric pump mainly includes stator and rotor；Institute
The stator stated is made of blade pump case and the motor stator being immobilized in the shell；The rotor is connected by rotor, rotor
It connects disk and impeller is constituted, rotor is fixed on rotor terminal pad outer end, and rotor terminal pad and impeller are fixed together, electricity
Machine rotor drives terminal pad and impeller high speed rotation；Two bearing shells of support electric pump rotor rotation are fixed on close to blade pump case
Centerline, and axially position electric pump rotor.
The motor stator and rotor carries out water-proofing treatment.
The medium of the electric pump conveying flow to the gap location of motor stator and rotor along the gap of bearing shell,
Motor is carried out from cooling.
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, the direct impeller rotation of rotor.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.The present invention without
Axis blade electric pump can be applied in all original places using motor-driven vane pump unit.
Detailed description of the invention
Fig. 1 is the cross-section structure schematic diagram of the shaftless blade electric pump of the present invention.
In figure, 1, motor stator, 2, rotor, 3, terminal pad, 4, impeller, 5, bearing shell, 6, shell.
Specific embodiment
In the accompanying drawings, the shaftless blade electric pump of the present invention mainly includes stator and rotor；The stator is by blade pump case 6
It is formed with the motor stator 1 being fixed in shell 6；The rotor is made of rotor 2, rotor terminal pad 3 and impeller 4,
Rotor 2 is fixed on 3 outer end of rotor terminal pad, and rotor terminal pad 3 and impeller 4 are fixed together, and rotor 2 drives
4 high speed rotation of terminal pad 3 and impeller；Two bearing shells 5 of support electric pump rotor rotation are fixed on close to the center of blade pump case 6
At line, and axially position electric pump rotor.The motor stator 1 and rotor 2 carries out water-proofing treatment.The electric pump
The medium of conveying flow to the gap location of motor stator 1 and rotor 2 along the gap of bearing shell 5, carries out to motor self cooling
But.The media implementation self-lubricating conveyed at the bearing shell 5 by electric pump.The present invention is that a kind of vane pump and the fusion of motor height exist
A kind of shaftless blade electric pump of conveying liquid medium together.The shaftless blade pump structure is simple, small in size, light-weight, material
Material consumption is lacked, and unpowered loss, work efficiency is high, and noise is small, can apply in all original use motor-driven vane pump units
Place.
