The utility model is composed of a stator iron core, a rotor iron core, a motor shaft, a stator winding, a magnetic transmission wheel, a permanent magnet, a partition board, and an impeller. A motor protecting device is arranged on one end cover of a motor. The rotor iron core is fixed on the motor shaft. The permanent magnet is enchased on the transmission wheel and is fixed on the motor shaft. An impeller seat for supporting the impeller is fixed on the partition board. The permanent magnet is fixed on the edge of the impeller. The utility model has the advantages of scientific conception, artful design, easy processes, reliable performance, low cost, full no leakage, high efficiency, and long service life. The utility model can be widely used in liquid conveying industry.
Description
The utility model relates to liquid and carries a kind of non-leakage magnetic pump-unit of using in the industry.
At present, it is very general to use industries such as Ordinary Centrifugal Pumps, pipeline mounted pump, canned motorpump, submersible pump in the industries such as industrial and agricultural production at home and abroad, military project national defence, general centrifugal pump is made up of impeller, suction chamber, delivery chamber, pump shaft, shaft sealer, bearing, coupling etc., according to the purposes difference of pump, impeller is divided into open type, semi-open type and enclosed.These conventional construction complexity, component are many, friction points is many, vibration is big, the noise height, life-span is short, make pump be in best operating point, must often safeguard it, adjust, maintenance, thereby its workman's workload is strengthened, the labor intensity height, the pump in the work has considerable part to exist efficient not high at present, more and the problem such as leakages in various degree of fault also has the no-leakage pump of use aborning, this pump adopts the electric stator of shielding, rotor winding way addresses the leakage concern, because technological requirement height, manufacture difficulty is big, makes valuable product, has influenced wider applying.Therefore develop a kind of non-leakage magnetic pump is the new problem of scientific research anxious to be solved both at home and abroad always.
The purpose of this utility model be exactly for a kind of novel science, project organization exquisiteness are provided, manufacturing process is easy, product performance are reliable, cost is low, do not have leakage fully, non-maintaining, efficient is high, the life-span is long, widely used a kind of non-leakage magnetic pump.
The purpose of this utility model is achieved in that whole device is by insulated cable; sealing gland; handle; ground joint; top cover; electric motor protective device; electric motor end cap; upper bearing (metal); stator iron core; rotor iron core; motor shaft; stator coil; drive wheel; thrust bearing; permanent magnet; dividing plate; impeller base; impeller; pump case; filter screen; support; hose coupling is formed; on motor shaft, install bearing; electric motor end cap is contained on the upper bearing (metal); electric motor protective device is installed on the electric motor end cap; sealing gland is installed on the electric motor end cap; ground joint is fixed on the top cover; insulated cable; sealing gland is installed on the top cover top; handle is fixed on the top cover right side and together it is installed on the electric motor end cap; rotor iron core is fixed on the motor shaft; stator iron core is installed in the support tube; support is fixed on the electric motor end cap; stator coil is loaded on the stator iron core; permanent magnet is inlaid on the drive wheel and is fixed on the motor shaft; thrust bearing is installed on the dividing plate; the impeller base that supports impeller is fixed on the dividing plate; permanent magnet is inlaid on the impeller edge; pump case is fixed on the support; filter screen is fixed on the pump case, on the hose coupling mounted pump housing.A double side electric motor end cap and the part pump case done of dividing plate.Stator iron core and stator coil energising back produce magnetic field causes rotor iron core and drive wheel to rotate direct drives impeller.Permanent magnet material can be a neodymium iron boron, also can be aluminium nickel cobalt or ferrite.Main points of the present invention are its structural type and working principle.Its working principle and using method are: behind electrical power, drive wheel rotates thereupon, the permanent magnet that permanent magnet on the drive wheel sees through on the dividing plate drives impeller is done rotation synchronously, here not additional any other device of the rotation of impeller, magnetic force by permanent magnet on the drive wheel drives fully, reaches the purpose of pumping liquid.Lubricating between impeller and the impeller base by being transferred liquid as the oiling agent selflubricating, the material that for this reason requires these positions to use has good self lubricity, heat-resistant antifriction and lower friction factor, when making the impeller rotation, impeller and impeller base obtain lubricated fully and cooling.Permanent magnet is selected appropriate, and pump not only can be put operation best worker all the time, and can also play the effect of protection motor when impeller generation stall.
A kind of non-leakage magnetic pump compared with prior art has following advantage:
1, change the kind of drive, no shaft sealer does not have leakage fully;
2, check oiling, the cancellation operating repairs on schedule;
3, simple and compact for structure, volume is little, and is in light weight, and noise is low, accomplishes the unification of pump machine;
4, manufacturing process is easy, and difficulty of processing is little, and product cost is low;
5, good airproof performance does not have leakage fully, reduces Maintenance and Repair, increases work efficiency;
6, component are few, and friction factor is little, and fault is few, and thermal conductivity is good, and the life-span is long.
Concrete structure of the present utility model is provided by following examples and accompanying drawing thereof.
