At present, employed induction washing electric pump on the dishwasher, drive motor mostly is monopole asynchronous motor, most sealabilities that adopt mechanical seal to realize pump on the mounting structure of pump case and motor.Because mechanical seal is had relatively high expectations to the installation concentricity of static and dynamic sealing spare, planeness, roughness etc., be difficult to control when manufacturing and designing, so the seepage phenomenon often appears in dishwasher, bring potential safety hazard to people's life.
The model utility content
The purpose of this utility model is to consider the problems referred to above and a kind of situation of leaking that can improve effectively when washing electric pump work is provided, and improves the brush DC circulating water pump of the reliability of sealing system work.The utility model high working efficiency, compact structure, variable-speed, operate steadily, noise vibration is little.
The technical solution of the utility model is: include pump case, following pump case, seal ring, dividing plate, rotor assembly, rotor shaft, bearing, stator assembly, winding coil, rubber ring, wherein going up pump case is connected with following pump case, form a cavity Q, dividing plate by with last pump case, following pump case interconnect cooperation, cavity Q is divided into two cavity Q1 and Q2, impeller is placed on respectively among cavity Q1 and the Q2 by being connected of rotor shaft with rotor assembly, bearing is assemblied in down respectively on pump case and the dividing plate, rotor assembly is supported and locatees, have on the dividing plate and make water flow into cavity Q2 from cavity Q1, thereby bearing is played the aperture of lubrication, stator assembly is assemblied in down on the pump case, be looped around the outside of cavity Q2, and align with rotor assembly, lay winding coil on the stator assembly.
The above-mentioned junction plane of going up between pump case and the following pump case seals by seal ring.
Above-mentioned rotor assembly adopts the plastic structure of permanent magnet.
The above-mentioned pump case of going up is connected with the mode of following pump case by the rotation fastening.
The above-mentioned pump case of going up adopts welding to be connected with following pump case.
Above-mentioned bearing is equipped with outward can alleviate rotor assembly when rotated because of uneven and the vibrative rubber ring of torque pulsation.
The Placement of aforementioned barriers and last pump case, following pump case is the fastening-pressing type linkage structure.
Above-mentioned bearing is a sliding bearing.
The utility model has been cancelled the mechanical seal structure of water pump commonly used, with the dynamic seal (packing) architecture advances is the static sealing structure, change the dry type rotor structure into wet type rotor structure that rotor is under water, thereby the possibility of seepage when greatly reducing the electric pump operation, the situation of leaking when effectively having improved the work of washing electric pump has improved the reliability of sealing system work.And characteristics such as the employing non-brush permanent-magnet DC motor has high efficiency, compact structure, variable-speed, operates steadily, and noise vibration is little.In addition, the utility model can be realized stepless time adjustment, and same electric pump goes for above the dishwasher of different flow lift requirement.The utility model is that a kind of design is ingenious, function admirable, convenient and practical brush DC circulating water pump.
