Abstract
The utility model relates to a daily water heating device, in particular to a micro permanent magnetic submersible pump without a dead point. Both sides of a permanent magnetic rotor are provided with silicon steel sheets, and one end of each silicon steel sheet is provided with permanent magnetic steel. The utility model has the advantages of reasonable and simple structure, eliminating running dead point, safe use, and the like.
Description
Technical field
The utility model relates to a kind of daily water consumption heating equipment, especially relates to a kind of not with the miniature permanent magnetism submersible pump at dead point.
Background technique
All in the market heating pumps all have certain deficiency in operation process.Because common p-m rotor water pump, its coil magnetic field is that the two poles of the earth become 180 ° of alternate, and when the dipolar magnetic field of p-m rotor followed coil magnetic field in a straight line, the suffered moment of p-m rotor will equal zero always, make p-m rotor to start, form the dead point.And common submersible pump, separates between casting glue and the power line after the long-time heating easily because power line directly is placed in the liquid, makes liquid enter power line, thereby causes the water pump short circuit.
Summary of the invention
The utility model mainly is at the existing in prior technology complex structure, is easy to generate the dead point in the running, uses the technical problem of uneasy congruence, provides a kind of rational in infrastructure simple, eliminates the operation dead point, miniature permanent magnetism submersible pump safe in utilization.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals: described p-m rotor both sides are provided with silicon steel plate, and one of silicon steel plate is provided with permanent magnetic steel.Permanent magnetic steel has increased the starting torque of water pump, eliminates the dead point.
As preferably, offer the lighting outlet pillar on the described pump shell, hollow in the lighting outlet pillar is laid power line.The lighting outlet pillar is isolated power line and liquid mutually, avoids causing the power line short circuit because of long-term heating, and is safe and reliable.
As preferably, offer breach on the described p-m rotor, breach and permanent magnetic steel are in the same plane, and this plane is horizontal by an angle, and angular range is between 15 °-30 °.Make the dipolar magnetic field of p-m rotor follow coil magnetic field not on same straight line, the suffered moment of p-m rotor will can not equal zero, thereby eliminate the dead point.
As preferably, described pump shell and silicon steel plate filling have encapsulating, and permanent magnetic steel is fixed on the silicon steel plate by encapsulating.
Therefore, the utlity model has rational in infrastructure simply, eliminate the operation dead point, characteristics such as safe in utilization.
Description of drawings
Accompanying drawing 1 is an overall structure schematic representation of the present utility model;
Accompanying drawing 2 is A-A structural representations of the present utility model.
Embodiment
Below by embodiment, and in conjunction with the accompanying drawings, the technical solution of the utility model is described in further detail.
Embodiment 1: p-m rotor 1 both sides are provided with silicon steel plate 2, and 2 one of silicon steel plates are provided with permanent magnetic steel 3; Permanent magnetic steel has increased the starting torque of water pump, eliminates the dead point.Offer lighting outlet pillar 5 on the pump shell 4, hollow in the lighting outlet pillar 5 is laid power line; The lighting outlet pillar is isolated power line and liquid mutually, avoids causing the power line short circuit because of long-term heating, and is safe and reliable.Offer breach 6 on the p-m rotor, breach 6 is in the same plane with permanent magnetic steel 3, and this plane is horizontal by an angle, and angle is 15 °; Make the dipolar magnetic field of p-m rotor follow coil magnetic field not on same straight line, the suffered moment of p-m rotor will can not equal zero, thereby eliminate the dead point.Pump shell 4 has encapsulating with silicon steel plate 2 fillings, and permanent magnetic steel 3 is fixed on (as illustrated in fig. 1 and 2) on the silicon steel plate 2 by encapsulating.
