Description
Technical field
The utility model belongs to suction pump applied technical field, and in particular to a kind of direct current portable pump.
Background technology
DC water pump is the machinery for conveying liquid or being pressurized liquid.During pump working, coil and commutator rotation, magnet steel
Do not turn with carbon brush, the alternating change of the direction of the winding current is completed with the commutator and brush of motor rotation.
Brushed DC pump working principle, shortcoming：As long as motor, which rotates carbon brush, will produce abrasion, water pump operation is to necessarily
When, carbon brush abrasion gap becomes big, and sound can also increase therewith, and carbon brush, which cannot play, after continuously running hundreds of hours changes
To effect.Brushless electric machine formula DC water pump operation principle, electric motor type brushless direct-current water pump is added using brshless DC motor
Formed after upper impeller, axle and the impeller of motor connect together, shortcoming：There is gap between the stator and rotor of water pump,
Usage time, which has grown water and can penetrate into motor inside motor, to be easy to burn out.
Therefore, a kind of direct current portable pump is provided based on above mentioned problem, the utility model.
