Description
Technical field
The present invention relates to pump industry machinery fields, relate in particular to a kind of no motor shaft two-stage and directly drive 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
Two-stage or multistage blade electric pump are made of two-stage or multistage blade pump and two units of motor.The power of motor is by rotor
It is transferred to motor shaft, then pump shaft is transferred to by shaft coupling, drives the impeller rotary work of vane pump；Pump structure shape described above
Formula and transmission mode can only be delivered power to pump shaft by motor output shaft, can just make pump work.Due to the transmission using axis
And work, cause the volume of electric pump big, 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 no motor shaft two-stages directly to drive blade electricity
Pump, the 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: this without motor shaft two-stage directly drive blade electric pump include stator and
Rotor；The stator is made of electric pump shell, motor stator, front cover, rear cover and bearing shell；Motor stator is fixed on electric pump shell
Interior, front cover, rear cover are separately fixed at the both ends of electric pump shell, and bearing shell is separately mounted in front cover and rear cover；The rotor by
Rotor, rotor connector sleeve, first order impeller, pump shaft, thrust disc and second level impeller are constituted；First order impeller, the second level
Impeller is respectively and fixedly installed on pump shaft, and second level impeller is fixed in rotor connector sleeve, is fixedly connected with outside rotor connector sleeve
Rotor, thrust disc cover on pump shaft between impeller and bearing shell.
The motor stator and rotor carries out water-proofing treatment, and the medium of the electric pump conveying is fixed along motor
The gap of son and rotor is flowed, and is cooled down to motor.
The rotor uses permanent-magnet material, and bearing shell uses self-lubricating material.
The motor stator can use brush DC winding, adjustable speed or run at high speed.
The electric pump can also directly can be gone here and there more electric pumps using bolt or other means with separate unit installation and operation
It is linked togather installation and operation.
When work, the electromagnetic field driving motor rotor high speed rotation of motor stator electric pump, rotor drives rotor connection
Set, second level impeller, pump shaft, first order impeller high speed rotation, liquid medium export after being pressurizeed after being inhaled by both stage impellers.
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 this without motor shaft two-stage directly drive blade electric pump with
Traditional motor driven blade pump work compares the volume for reducing motor, blade pump assembly, has saved lot of materials, directly drives
The dynamic energy loss for reducing power train process, improves work efficiency, changes the unit type of cooling, reduce unit and make an uproar
Sound.The present invention directly drives blade electric pump without motor shaft two-stage and can apply in all original fields using motor-driven vane pump unit
Institute.
