A magnetic drive pump includes a magnetic coupling comprising an external magnetic rotor and an internal magnetic rotor. The external magnetic rotor is driven by a separate motor. The external magnetic rotor is positioned radially out of a sealing wall. The internal magnetic rotor is positioned radially within the sealing wall so that the rotation of the internal magnetic rotor causes the pump rotor to rotate. The pump rotor drives a centrifugal pump impeller to move a liquid. A bubble detector is positioned off the wall so that it is on a dry side of the pump.

BREVE DESCRIÇÃO DOS DESENHOS A figura 1 é uma vista de seção transversal através da bomba inventiva. A figura 2 é um detalhe da montagem de uma sonda de detector de bolha.BRIEF DESCRIPTION OF THE DRAWINGS Figure 1 is a cross-sectional view through the inventive pump. Figure 2 is a detail of the assembly of a bubble detector probe.
DESCRIÇÃO DETALHADA DA FORMA DE CONCRETIZAÇÃODETAILED DESCRIPTION OF THE EMBODIMENT
PRFERIDAPreferred
Uma bomba de acionamento magnético é ilustrada na figura 1, tendo uma parede de vedação 22 que separa um lado seco 23 a partir de um lado úmido 40 para uma bomba de fluido. Um motor separado aciona um eixo 28, através de uma carcaça de suporte 24. O eixo 28 aciona um rotor magnético externo 30, que é posicionado fora da parede 22. Fluxo magnético passa através da parede 22 e aciona um rotor magnético interno 32. Um impulsor de bomba centrífuga 34 é conectado ao rotor magnético interno 32. Fluido passa de uma entrada 35 para o impulsor 34, e é impulsionado para uma saída 37.A magnetic drive pump is illustrated in Figure 1, having a sealing wall 22 separating a dry side 23 from a wet side 40 for a fluid pump. A separate motor drives an axis 28 via a support housing 24. The axis 28 drives an external magnetic rotor 30 which is positioned outside the wall 22. Magnetic flux passes through the wall 22 and drives an internal magnetic rotor 32. One centrifugal pump impeller 34 is connected to internal magnetic impeller 32. Fluid passes from an inlet 35 to impeller 34, and is driven to an outlet 37.
Uma sonda de detector de bolha 36 é posicionada fora da parede 22 e se comunica com um controle 38. A sonda pode ser uma sonda ultra-sônica que transmitirá e receberá um sinal ultra-sônico. A transmissão de sinal através do líquido é diferente para a transmissão de sinal através de gás. Por conseguinte, a sonda pode determinar se o fluido dentro da câmara úmida é líquido, gás ou uma mistura de líquido e gás. A bomba de acionamento magnético inclui um lado “úmido” 40, que recebe algum do líquido sendo bombeado pelo impulsor 34, de modo que o líquido pode circular em tomo dos componentes radialmente dentro da parede de vedação 22. Em adição, um lado “seco” 23 é posicionado radialmente fora da parede e não recebe o líquido. A sonda 36 é posicionada no lado seco 23.A bubble detector probe 36 is positioned off wall 22 and communicates with a control 38. The probe may be an ultrasonic probe that will transmit and receive an ultrasonic signal. Signal transmission via liquid is different for signal transmission through gas. Accordingly, the probe can determine if the fluid within the wet chamber is liquid, gas or a mixture of liquid and gas. The magnetic drive pump includes a "wet" side 40, which receives some of the liquid being pumped by the impeller 34, so that liquid can circulate around the components radially within the sealing wall 22. In addition, a "dry" side ”23 is positioned radially off the wall and does not receive liquid. The probe 36 is positioned on the dry side 23.
Como pode ser apreciado, a sonda 36 é voltada para uma porção do lado úmido 40, espaçada do impulsor 34. Este posicionamento alinha a sonda 36 com uma porção da câmara que é separada do impulsor por meio de uma parede de carcaça 100.As may be appreciated, the probe 36 faces a wet side portion 40 spaced from the impeller 34. This positioning aligns the probe 36 with a portion of the chamber which is separated from the impeller by a housing wall 100.
Como pode ser apreciado da figura 2, e com referência à figura 1, a sonda 36 é posicionada para ser oposta a um suporte de bucha 100. Uma parede de carcaça externa 101 recebe um arranjo de tampa/porca 110 para fixar e reter a sonda na carcaça. A parede de vedação 22 é formada de material não ferromagnético. A tecnologia para formar um transmissor ultra-sônico apropriado para enviar um sinal através da parede 22, e contra a superfície oposta, é conhecida. Essencialmente, o controlador 38 será capaz de determinar se bolhas de vapor ou de gás estão dentro do fluido de bomba pela análise do sinal retomado. Embora a tecnologia para prover uma tal sonda seja conhecida, uma tal sonda não foi utilizada desta maneira não invasiva.As may be appreciated from Figure 2, and with reference to Figure 1, the probe 36 is positioned to be opposed to a bushing holder 100. An outer casing wall 101 receives a cap / nut arrangement 110 for securing and retaining the probe. in the carcass. The sealing wall 22 is formed of non-ferromagnetic material. The technology for forming an appropriate ultrasonic transmitter to send a signal through the wall 22, and against the opposite surface, is known. Essentially, the controller 38 will be able to determine if steam or gas bubbles are within the pump fluid by analyzing the resumed signal. Although the technology for providing such a probe is known, such a probe has not been used in this non-invasive manner.
Embora uma forma de concretização desta invenção tenha sido revelada, um trabalhador de conhecimento comum nesta arte reconhecería que certas modificações cairíam dentro do escopo desta invenção. Por esta razão, as seguintes reivindicações devem ser estudadas para determinar o verdadeiro escopo e conteúdo desta invenção.While an embodiment of this invention has been disclosed, one of ordinary skill in the art would recognize that certain modifications would fall within the scope of this invention. For this reason, the following claims should be studied to determine the true scope and content of this invention.
