Abstract

MEJORAS INTRODUCIDAS EN BOMBAS ACCIONADAS POR MOTOR SINCRONO PARA ELECTRODOMESTICOS. CONSISTE EN DOTAR AL TOPE (6) DEL RODETE (1) DE LA BOMBA, DE UN AMORTIGUADOR (7), DE UN MATERIAL ELASTOMERO DE DUREZA APROPIADA, QUE QUEDA ENCAJADO ENTRE DICHO TOPE (6) Y LA PARED LATERAL DEL RODETE (1), AMORTIGUADOR CUYOS EXTREMOS (9) SOBRESALEN SENSIBLEMENTE CON RESPECTO AL TOPE PROPIAMENTE DICHO (6), CONSTITUYENDO LAS ZONAS DE IMPACTO PARA LA LEVA DE ARRASTRE (5) ASOCIADA AL ROTOR DEL MOTOR. DE ESTA MANERA EN LA MANIOBRA DE ARRANQUE LA LEVA DE ARRASTRE (5) IMPACTA SOBRE UN ELEMENTO BLANDO Y ELASTICO QUE ABSORBE BUENA PARTE DE LA ENERGIA Y QUE MINIMIZA EL RUIDO.IMPROVEMENTS INTRODUCED IN SYNCHRONOUS MOTOR DRIVEN PUMPS FOR APPLIANCES. IT CONSISTS TO PROVIDE TO THE TOP (6) OF THE PUMP IMPELLER (1), OF A SHOCK ABSORBER (7), OF A ELASTOMER MATERIAL OF APPROPRIATE HARDNESS, WHICH FITS BETWEEN SUCH TOPPED (6) AND THE SIDE WALL OF THE IMPELLER (1) , SHOCK ABSORBER WHOSE EXTREMS (9) EXCEED SENSITIVELY WITH RESPECT TO THE STOP PROPERLY SAID (6), CONSTITUTING THE ZONES OF IMPACT FOR THE DRIVE CAM (5) ASSOCIATED WITH THE MOTOR ROTOR. IN THIS WAY, THE DRIVE CAM (5) IMPACTS ON A SOFT AND ELASTIC ELEMENT THAT ABSORBS A GOOD PART OF THE ENERGY AND THAT MINIMIZES THE NOISE.
