Abstract
The utility model relates to a permanent magnet miniature submerged pump, which is provided with an all-plastic pump body and a pouring encapsulation, wherein, the utility model can be insulated twofold, the inner part of a rotor cavity is provided with a rotor shaft and a permanent magnet rotor, the inner part of a spiral casing connected with the pump body is provided with an impeller and a liquid output opening, and a stator coil and a silicon steel sheet set of a stator are positioned in one pouring body. The utility model is characterized in that two symmetrical magnetic saturation notches are arranged on an inner groove of the silicon steel sheet set of the stator, one diversion groove is arranged in the rotor cavity is provided with one diversion groove, and accordingly, the permanent magnet rotor is not demagnetized, and operation noise is decreased.
Description
The utility model relates to a kind of permanent magnetism miniature immersible pump, and it belongs to as the coolant pump of industry equipment and liquid circulation pump.
Employed in the prior art permanent magnetism miniature immersible pump has the pump housing and the cast encapsulation of all-plastic, can double insulation, and its rotor adopts high performance permanent-magnet material.But it exists some common shortcomings, i.e. the rotor made of the permanent-magnet material of this kind submersible pump demagnetization easily in use causes the rotor torque deficiency, and rotating speed descends, and the flow of outlet liquid reduces, and lift reduces; Another shortcoming is, submersible pump noise in the running is bigger, and this is to cause owing to the flowing state of liquid in rotor chamber is bad.At above-mentioned shortcoming, the utility model has been proposed.
The purpose of this utility model is: a kind of permanent magnetism miniature immersible pump is provided, and it has overcome above-mentioned shortcoming, can make the unlikely increase under high voltage of effective magnetic field intensity excessive and cause p-m rotor demagnetization, has also reduced to cause simultaneously the eddy current of noise effectively.
The technical solution of the utility model is: be provided with a pump housing and a spiral case that is attached thereto, end at spiral case is the delivery outlet of liquid, the rotor that rotor shaft is housed in the rotor chamber of the pump housing and adopts high performance permanent magnetic materials to make, impeller is equipped with on top at rotor shaft, and it is positioned at spiral case; A pour mass is arranged in the pump housing, wherein be provided with stator coil,, be provided with stator silicon steel plate group, below stator coil, be provided with cable and communicate with power supply in the periphery of stator coil; On the inside groove of described stator silicon steel plate group, have the magnetic saturation breach of two symmetries; In the rotor chamber of the pump housing, have a guiding gutter that is used to reduce eddy current.Advantage of the present utility model is:
1. p-m rotor no longer demagnetizes, and makes rotor torque, rotating speed, liquid outlet flow and lift keep stable, thereby has improved working efficiency.
2. improve the flowing state of liquid in the rotor chamber, reduced eddy current, the noise when having reduced running, thus improved working life.
Consulting accompanying drawing below elaborates to embodiment of the present utility model:
Fig. 1 is a structural representation of the present utility model
Fig. 2 is the schematic top plan view of Fig. 1 middle pump body
Fig. 3 is the top plan view shape schematic representation of stator silicon steel plate group
As shown in the figure: the permanent magnetism miniature immersible pump is by all-plastic pump housing cast encapsulation, double insulation, comprise a pump housing 1 and the spiral case 2 that is attached thereto, in the rotor chamber 3 in the pump housing 1, the rotor 5 that rotor shaft 4 is housed and makes with high performance permanent magnetic materials, be provided with impeller 6 on the top of rotor shaft 4, impeller 6 is positioned at spiral case 2, and an end of spiral case 2 is outlets of liquid; Be provided with stator coil 7 in the pump housing 1, be provided with stator silicon steel plate group 8 in its periphery, the two all places pour mass 9; Below stator coil 7, be provided with cable and communicate with power supply; Open the magnetic saturation breach 11 of two symmetries on the inside groove of described stator silicon steel plate group 8, in the rotor chamber 3 of the pump housing 1, have a guiding gutter 12,, improve the flowing state of liquid in order to reduce the eddy current of liquid.Respectively be provided with an axle sleeve 13 at the two ends of rotor shaft 4, joint at the pump housing 1 and spiral case 2 is provided with a seal ring 14, one pad 15 is housed between rotor 5 and spiral case 2, side at the pump housing 1 is connected with a fixed plate 17 with some screws 16, is provided with some holes that are used for fixing the pump housing on fixed plate 17; In the bottom of the pump housing 1 base plate 18 is housed, it is connected with the pump housing with two elasticity cards with two screws.
The working principle of permanent magnetism miniature immersible pump is as follows: after it and power supply are opened, in stator coil 7, produce alternating magnetic field, 5 rotations of field drives p-m rotor, rotor 5 drive coaxial impeller 6 and rotate together, and liquid outlet from spiral case one end under the effect of the rotary centrifugal force of impeller 6 is exported.
