Shaftless blade electric pumpTechnical 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 bandThe birth of dynamic delivery pump, let us become with links in daily life simply in production, convenient.But it applies at presentElectric 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 couplingIt 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, drivesIt is mounted on the impeller rotary work of motor shaft blade pump.Pump structure form and transmission mode described above, can only pass through electricityMachine 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 causedGreatly, 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 volumesSmall, 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；InstituteThe stator stated is made of blade pump case and the motor stator being immobilized in the shell；The rotor is connected by rotor, rotorIt connects disk and impeller is constituted, rotor is fixed on rotor terminal pad outer end, and rotor terminal pad and impeller are fixed together, electricityMachine 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 caseCenterline, 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, eliminatingThe bearing of motor and vane pump, the direct impeller rotation of rotor.So the shaftless blade electric pump and traditional motor driveMovable vane piece pump work compares the volume for reducing motor, blade pump assembly, has saved lot of materials, directly driving reduces powerThe energy loss of transmission process, improves work efficiency, and changes the unit type of cooling, reduces unit noise.The present invention withoutAxis blade electric pump can be applied in all original places using motor-driven vane pump unit.

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 6It 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 drives4 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 6At line, and axially position electric pump rotor.The motor stator 1 and rotor 2 carries out water-proofing treatment.The electric pumpThe 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 coolingBut.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 existA kind of shaftless blade electric pump of conveying liquid medium together.The shaftless blade pump structure is simple, small in size, light-weight, materialMaterial consumption is lacked, and unpowered loss, work efficiency is high, and noise is small, can apply in all original use motor-driven vane pump unitsPlace.
