Abstract
"MECANISMO DE FLUIDO DE CAVIDADE PROGRESSIVA, APARELHO E MéTODO PARA USINAGEM". A usinagem eletroquímica é utilizada para gerar os perfis de lóbulos helicoidais do estator de uma bomba ou um motor de cavidade progressiva. Um forro elastomérico fino, de espessura uniforme é unido ao interior do estator, ou ao exterior do rotor. Onde o forro elastomérico deve ser ligado ao interior do estator, a ligação é incrementada ao se causticar eletricamente o interior do estator durante o processo de usinagem eletroquímica para produzir uma superfície áspera."PROGRESSIVE CAVITY FLUID MECHANISM, MACHINE AND METHOD FOR MACHINING". Electrochemical machining is used to generate the stator helical lobe profiles of a pump or a progressive cavity motor. A thin elastomeric liner of uniform thickness is attached to the inside of the stator or outside the rotor. Where the elastomeric liner must be bonded to the interior of the stator, the bonding is increased by electrically causing the interior of the stator during the electrochemical machining process to produce a rough surface.
