Description
Technical field
The present invention relates to a kind of magnetic drive pump.
Background technology
The structure of common water pump is will to be isolated with slidingtype water seal inside and outside water pump body, although slidingtype water seal is most
In the case of can play buffer action, but the sliding friction film of slidingtype water seal is easier to seep water, and is not entirely isolated inside and outside water pump
State, partially liq can be oozed out by sliding friction film faying face, micro when water pump is used as extracting poisonous or corrosive liquids
Leakage can be to water pump in itself and surrounding environment causes extreme influence, existing magnetic drive pump specially designs system aiming above mentioned problem
Completely isolated water pump inside and outside the pump housing made.
The structure of existing magnetic drive pump is a kind of to be driven by conventional motor 13 by the magnetic driving mechanism 14 of a centre
Pump shaft 15 rotates, and then makes a kind of pump of the rotation work of impeller 3 in pump housing A on pump shaft 15.With reference to shown in Fig. 1, described magnetic
The critical piece of force transmission mechanism 14 is outer magnet rotor（Also active p-m rotor is, by power rotor 16 and power rotor magnet steel
17 are formed）With interior magnet rotor（Also driven p-m rotor is, is made up of driven rotor 18 and driven rotor magnet steel 19）, interior magnet rotor
Separation sleeve 21 is provided between outer magnet rotor and forms annular seal space, pump shaft 15 and interior magnet rotor are enclosed in annular seal space so as to by the pump housing
Inside and outside completely isolated, motor 13 is fixed by motor flange 20 and the aft case of magnetic driving mechanism 14.Central shaft 6 drives outer magnetic
Rotor rotates, and outer magnet rotor fits through magnet rotor in magnetic force drive with interior magnet rotor and rotated, then drives pump shaft by interior magnet rotor
15 rotate, and make the rotation work of impeller 3 on pump shaft 15 in pump housing A.
Obviously, greatest problem existing for existing magnetic drive pump is to add one almost in order to completely isolated inside and outside the pump housing
With a same volume and weight of motor, complicated, cost is very high, and the troublesome transmission mechanism of care and maintenance, and because of electricity
Machine 13 need to carry out passing power by this intermediate by magnetic driving mechanism 14, it is difficult to ensure that magnetic driving mechanism operated for a long time
Problem will not be damaged or produced in journey.Therefore the functional reliability and service life of conventional magnetic pump are all difficult to be guaranteed,
Often increase maintenance cost, influence production and normal work.
The content of the invention
The present invention seeks to：There is provided one kind compared to conventional magnetic pump volume greatly to reduce, structure is more compact, manufacturing cost
It is lower, there is the magnetic drive pump of excellent cooling effect simultaneously for motor part.
The technical scheme is that：A kind of magnetic drive pump, including the pump housing, it is characterised in that before being separated with the inside of the pump housing,
In, rear three chambers, be provided with impeller in the front chamber, p-m rotor be provided with rear chamber；And the middle chamber is closed
Water proof chamber, the electromagnetic stator coordinated with p-m rotor is provided with it, by through lumen between the p-m rotor and impeller
The central shaft of room is connected.
Further, the heretofore described pump housing includes shell and pump housing rear shell in pump housing fore shell fixed successively, the pump housing, institute
State shell in the pump housing and form front chamber and rear chamber between pump housing fore shell and pump housing rear shell respectively；Integrally set on shell in the pump housing
In respect of the electromagnetic stator seat extended into rear chamber, electromagnetic stator is fixed on stator seat；Also include cage, the cage
It is fixed to by lock sleeve on stator seat, and the middle chamber of closing electromagnetic stator is formed together with the pump housing between shell, stator seat.
Further, axis hole is provided with heretofore described stator seat, the central shaft is assemblied in described by bearing
In axis hole, and p-m rotor is fixed on the central shaft and peripheral positioned at the electromagnetic stator, the p-m rotor and electromagnetism
Separated between stator by the cage.
Further, the same with routine techniques in the present invention, the electromagnetic stator includes stator core, the stator core
Some unwrapping wire grooves are distributed with upper uniform intervals, and unwrapping wire groove is built-in with stator coil；And the p-m rotor includes matching somebody with somebody by keyway
The rotor flywheel being fixed on central shaft is closed, uniform intervals are fixed with rotor magnetic steel on the rotor flywheel.
The heretofore described pump housing is provided with the entery and delivery port being connected with front chamber.
The present invention forms motor as in power source drive in real work, between the p-m rotor and electromagnetic stator
Mandrel rotates, and then drives the wheel rotation in front chamber that magnetic drive pump is operated.
It is an advantage of the invention that：
1. rotor of the present invention by the driven p-m rotor in existing magnetic drive pump magnetic driving mechanism directly as motor,
And substituted the active p-m rotor electromagnetic stator in magnetic driving mechanism, therefore it has thoroughly overturned setting for existing magnetic drive pump
Thinking is counted, the complicated inside and outside magnetic drives framework of existing magnetic drive pump is changed completely, greatly shortens and reduce conventional magnetic
The axial length and volume of pump so that magnetic drive pump overall structure is compacter, and volume is smaller, and weight is lighter, while effective section
Save material, save production and maintenance cost.
2. forward and backward chamber is liquid chamber in the present invention, Integral design stator seat again on shell in the pump housing, so that it is guaranteed that
Radiating can be implemented to stator seat and its electromagnetic stator by water cooling, so do not only has very well for electromagnetic stator part
Radiating effect, while eliminate conventional fan part and motor radiating shell, more conducively save material, save and be produced into
This.And it can eliminate fan noise, be truly realized volume, cost, radiating, noise reduction are taken into account.
