Description
Technical field
The present invention relates to pump industry machinery fields, relate in particular to a kind of shaftless blade electric pump of brushless, permanently.
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 pumps of brushless, permanently, should
Electric pump is small in size, and 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 of the brushless, permanently mainly include stator and
Rotor；The stator is made of blade pump case and the DC. brushless electric machine stator being immobilized in the shell；The rotor by
Permanent magnet machine rotor, rotor terminal pad, impeller are constituted, and permanent magnet machine rotor is fixed on rotor terminal pad outer end, rotor terminal pad
It is fixed together with impeller, permanent magnet machine rotor drives terminal pad and impeller high speed rotation；Support the rotation of electric pump rotor
Two bearing shells are fixed on the centerline close to blade pump case, and axially position electric pump rotor.
The DC. brushless electric machine stator and permanent magnet machine rotor carries out water-proofing treatment.
The medium of the described electric pump conveying flow to brushless motor stator and permanent magnet machine rotor along the gap of bearing shell
Gap location carries out from cooling motor.
The rotor of 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, 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.Due to motor
Rotor uses permanent-magnet material, improves electric efficiency；Motor stator uses brush DC winding, adjustable speed or runs at high speed.This hair
The bright shaftless blade electric pump of brushless, permanently can be applied in all original places using motor-driven vane pump unit.
