Description
"DISPOSIÇÃO APLICADA EM BOMBA DE DIAFRAGMA" "DIAPHRAGM PUMP ARRANGEMENT"
[001 ] Trata o presente relatório descritivo da solicitação de Patente de Modelo de Utilidade de uma inédita DISPOSIÇÃO APLICADA EM BOMBA DE DIAFRAGMA cujo destaque é apresentar os acessos, a 180Q entre si, dotados de roscas, o que permite o rosqueamento de conexão reta ou conexão ortogonal ao acesso de saída el ou entrada do fluido, possibilitando o uso da bomba tanto na horizontal com a conexão reta quanto na vertical com a conexão ortogonal, nesse caso específico para sua sobreposição à parede de reservatórios rotomoldados para o bombeamento de água, cujo fluxo se dá com o acionamento de uma alavanca manual que impõe um deslocamento no diafragma, que é recoberto por uma tampa de inspeção removível da borda de fixação nervurada, facilitando assim o acesso ao aludido diafragma. [001] This report describes the Utility Model Patent Application of an unpublished DIAPHRAG PUMP ARRANGEMENT, the highlight of which is the 180 Q accessions with threads, which allows the straight connection threading. or orthogonal connection to the fluid outlet port or inlet, enabling the pump to be used both horizontally with the straight connection and vertically with the orthogonal connection, in this particular case for its overlap to the wall of rotomolded reservoirs for pumping water, whose flow occurs with the actuation of a hand lever that imposes a displacement in the diaphragm, which is covered by a removable inspection cap of the ribbed fixing edge, thus facilitating access to the said diaphragm.
[002] A bomba de diafragma inovada tem como campo de aplicação preferencial os reservatórios e cisternas rotomoldados, porém não limitado a esses produtos, podendo também ser utilizada para retirada de água de bordo de embarcações, transferências e bombeamento de líquidos em geral. [002] The innovative diaphragm pump has as its preferred field of application rotomolded reservoirs and tanks, but not limited to such products, and may also be used for withdrawal of water from vessels, transfers and pumping of liquids in general.
[003] É de conhecimento dos técnicos no assunto que a bomba de diafragma, também conhecida como bomba de membrana, é um equipamento de deslocamento positivo, geralmente alternativo, em que o diferencial de pressão necessário ao fluxo do fluido se dá pelo movimento de uma parede elástica (diafragma / membrana) que varia o volume da câmara ciclicamente. Válvulas de retenção controlam o direcionamento do fluxo no sentido da abertura para a saída da câmara. It is well known to those skilled in the art that the diaphragm pump, also known as the diaphragm pump, is a generally alternative positive displacement device in which the pressure differential required for fluid flow is caused by the movement of a elastic wall (diaphragm / membrane) that changes chamber volume cyclically. Check valves control flow direction from the opening to the chamber outlet.
[004] O atual estado da técnica antecipa alguns documentos de patentes que versam sobre bombas de diafragma de sobrepor, como o PI 8206096-7 que compreende uma bomba com um corpo que conforma uma câmara com abertura de entrada e abertura de saída alinhadas e providas de válvulas de retenção, tendo apoiado em sua borda um diafragma fixado por um suporte nervurado, no qual se articula uma alavanca de acionamento com um prolongamento inferior, que é preso em pino central agregado centralmente no referido diafragma. The present state of the art anticipates some patent documents dealing with overlap diaphragm pumps, such as PI 8206096-7 which comprises a pump with a body forming a chamber with inlet and outlet ports aligned and provided. check valves having a diaphragm attached to it by a ribbed support, on which an actuating lever with a lower extension is hinged, which is attached to a centrally attached central pin in said diaphragm.
[005] A anterioridade supracitada apesar de poder ser aplicada em reservatórios e porões de embarcações, por ter os acessos a 180Q tem posição de trabalho preferencial na horizontal e vertical desde que os acessos estejam alinhados com as
tomadas de água e de bombeamento. No caso de sua sobreposição à parede vertical de um reservatório rotomoldado já causaria uma torção na mangueira de condução de fluido devido a ortogonalidade gerada. Outrossim, o diafragma desta anterioridade fica exposto e sujeito a intempéries e a ação mecânica de ferramentas e outros dispositivos que podem danificá-los durante o uso. Although the aforementioned anteriority can be applied to reservoirs and holds of vessels, having the accesses to 180 Q has preferential working position horizontally and vertically provided that the accesses are aligned with the water and pumping outlets. Overlapping the vertical wall of a rotomolded reservoir would already cause the fluid conduction hose to twist due to the orthogonality generated. Furthermore, the diaphragm of this anteriority is exposed and subject to weathering and the mechanical action of tools and other devices that may damage them during use.
[006] O documento de patente BR 20 2013 0267967 7 - é descrito como uma bomba manual compreendendo uma base de formato cilíndrico, uma membrana em forma de disco e definindo junto com a base uma câmara de sucção de líquidos, com tampa de fixação e proteção da membrana com forma de copo cónico único e com borda nervurada fixada diretamente na base, no qual se articula uma alavanca de acionamento com um prolongamento inferior, que é preso em pino central agregado centralmente no referido diafragma. A abertura de entrada e a saída são dispostas ortogonalmente. Patent document BR 20 2013 0267967 7 - is described as a hand pump comprising a cylindrical shaped base, a disc shaped membrane and defining together with the base a liquid suction chamber with fixing cap and Single tapered cup-shaped membrane guard with ribbed edge fixed directly to the base, on which a lower-extending drive lever is hinged, which is secured to a centrally attached center pin in said diaphragm. The inlet opening and the outlet are arranged orthogonally.
[007] A bomba do pedido de patente acima tem os acessos de entrada e saída do fluido ortogonais, o que a habilita a ser utilizada em reservatórios e cisternas, sendo que o alinhamento do acesso de saída voltado para cima possibilita a constrição / dobra de interrupção na mangueira de condução do fluido, afetando assim a eficiência do sistema de bombeamento, e em contrapartida também não está habilitada a ser utilizada em bases de apoio horizontais e verticais em aplicações com necessidades de promover alinhamento entre a abertura e a saída, comum entre sistemas de retirada de água de bordo de embarcações, transferências e bombeamento de líquidos em geral. The above patent application pump has orthogonal fluid inlet and outlet accesses, enabling it to be used in reservoirs and cisterns, and the alignment of the upwardly facing outlet access enables constriction / folding of interruption in the fluid conduction hose, thus affecting the efficiency of the pumping system, and in contrast is also not suitable for use on horizontal and vertical support bases in applications that need to promote alignment between opening and outlet, common between waterborne vessel withdrawal, transfer and liquid pumping systems in general.
[008] Assim, diferentemente do produto inovado, a bomba tal como é conhecida é deficiente em seu alinhamento de saída gerando condição indesejada de restrição do fluxo do fluído. A dita bomba também não permite a sobreposição em sistemas com base de apoio, horizontal e vertical que necessitam aberturas de entrada e saída do fluido alinhadas. Thus, unlike the innovated product, the pump as it is known is deficient in its outlet alignment generating undesired fluid flow restriction condition. Said pump also does not allow overlap in horizontal and vertical support base systems that require aligned fluid inlet and outlet ports.
[009] Outro aspecto negativo do documento de patente BR 20 2013 0267967 7 está relacionado ao sistema da tampa unificado com a borda nervurada, que não permite realizar a inspeção do diafragma / membrana sem a desmontagem total da tampa de proteção e da fixação da membrana, significando que apenas para evidenciar as condições de ressecamento ou outro tipo de desgaste natural da borracha do
diafragma ao longo do tempo o usuário tem que necessariamente desmontar a tampa, por consequência a bomba. [009] Another negative aspect of patent document BR 20 2013 0267967 7 is related to the unified lid system with the ribbed edge, which does not allow the inspection of the diaphragm / membrane without the complete disassembly of the protective cap and the membrane fixation. , meaning that just to highlight the drying conditions or other natural wear of the rubber of the diaphragm over time the user has to necessarily disassemble the cover, consequently the pump.
[010] Ciente do atual estado da técnica, suas lacunas e limitantes, o inventor, pessoa afeita à matéria em apreço, após observações e pesquisas criou a DISPOSIÇÃO APLICADA EM BOMBA DE DIAFRAGMA, em questão, que apresenta os acessos de entrada e saída do fluido alinhados axialmente no corpo base da câmara da bomba e graças ao acabamento roscável existente nestes acessos permitem o uso de conexão tanto ortogonal quanto reta, o que a habilita a ser utilizada em reservatórios e cisternas quando da utilização de conexão ortogonal, já quando utilizada conexão reta, também permite a sobreposição em sistemas com base de apoio, horizontal e vertical com as aberturas de entrada e saída do fluido alinhadas. [010] Aware of the current state of the art, its shortcomings and limitations, the inventor, a person concerned with the subject under consideration, has created the DIAPHRAGM PUMP ARRANGEMENT in question, which provides access to and from the axially aligned fluids in the base chamber of the pump chamber and thanks to the threadable finish in these accesses allow the use of both orthogonal and straight connection, which enables it to be used in reservoirs and cisterns when using orthogonal connection, when used straight, also allows overlap in horizontal and vertical support base systems with aligned fluid inlet and outlet ports.
[01 1 ] Na DISPOSIÇÃO APLICADA EM BOMBA DE DIAFRAGMA, quando da sobreposição à parede do reservatório / cisterna, o acesso de entrada da câmara de bombeamento, com a rosca externa e acoplado á conexão ortogonal permanece em posição ideal para receber a mangueira de condução do fluido, sem formação de dobra de interrupção do fluxo. Nesse caso, a própria parede do reservatório / cisterna serve como base para apoio e sustentação da bomba. [01 1] In DIAPHRAGM PUMP ARRANGEMENT, when overlapping the reservoir / cistern wall, the inlet access of the pumping chamber with the external thread and coupled to the orthogonal connection remains in the ideal position to receive the conduction hose. fluid, without formation of flow interruption bending. In this case, the reservoir / cistern wall itself serves as a base for pump support and support.
[012] Na DISPOSIÇÃO APLICADA EM BOMBA DE DIAFRAGMA, quando da sobreposição em sistemas com base de apoio, horizontal e vertical com os acessos de entrada e saída do fluido alinhados, o acesso de entrada e de saída da câmara de bombeamento, com rosca externa, quando acoplados á conexão reta permanece e em posição ideal para receber a mangueira de condução do fluido mantendo o mesmo alinhamento da direção horizontal ou vertical da base de apoio. [012] In DIAPHRAM PUMP APPLIED ARRANGEMENT, when overlapping in horizontal and vertical support base systems with fluid inlet and outlet accesses aligned, the pump chamber inlet and outlet access, with external thread when coupled to the straight connection remains in an ideal position to receive the fluid conduction hose while maintaining the same alignment of the horizontal or vertical direction of the support base.
[013] Na DISPOSIÇÃO APLICADA EM BOMBA DE DIAFRAGMA, a tampa de inspeção e de proteção da membrana é removível, ou seja, é dissociada da borda de fixação nervurada no qual se articula a alavanca, essa característica possibilita a inspeção do diafragma sem a necessidade de desmontagem da bomba do reservatório.
[014] A seguir, para uma total visualização de como construir e como dar aplicação funcional à bomba de diafragma, objeto da presente patente de modelo de utilidade, e melhor elucidar o relatório descritivo, explica-se a inovação, com referência aos desenhos anexos, nos quais estão representadas de forma ilustrativa e não limitativa: [013] In DIAPHRAGM PUMP APPLIED ARRANGEMENT, the membrane protective and inspection cap is removable, ie it is dissociated from the ribbed attachment edge on which the lever pivots, this feature enables diaphragm inspection without the need pump tank disassembly device. Next, for a full view of how to construct and how to functionally apply the diaphragm pump, object of the present utility model patent, and better elucidate the descriptive report, the innovation is explained with reference to the accompanying drawings. , in which they are represented by way of illustration and not limitation:

[015] A DISPOSIÇÃO APLICADA EM BOMBA DE DIAFRAGMA notadamente refere- se a uma bomba (1 ) de diafragma (2) acionada por alavanca (3) manual, em que o acesso de entrada (4) é alinhado, lateralmente a câmara (5) de bombeamento, a 180Q
com o acesso de saída (6), ambos acessos (4 e 6) dotados de rosca (R), o que possibilita o acoplamento de conexões ortogonal (7) e conexões reta (8) para o bombeamento com pontos de tomadas desalinhados (A e B) e alinhados (C e D), respectivamente, efetivado pela diferença de pressão promovida pelo deslocamento do diafragma (2), que é sobreposto por uma tampa (10) de proteção removível fixada de forma não definitiva por travas (1 1 ) a borda (12) nervurada. [015] THE DIAPHRAM PUMP ARRANGEMENT notably relates to a hand-lever driven diaphragm pump (1) (2), wherein the inlet access (4) is aligned laterally to the chamber (5 ) pumping at 180 Q with the outlet access (6), both accessions (4 and 6) are threaded (R), which enables the coupling of orthogonal connections (7) and straight connections (8) for pumping with misaligned outlet points (A and B) and aligned (C and D), respectively, effected by the pressure difference promoted by the displacement of the diaphragm (2), which is superimposed by a removable protective cap (10) not permanently fixed by latches (11). the ribbed edge (12).
[016] Mais particularmente, a bomba (1 ) de diafragma (2) inovada é configurada por uma câmara de bombeamento (5) que possui lateralmente um acesso de entrada (4) alinhado a 180Q com um acesso de saída (6), ambos acessos roscados (R) para recepção e acoplamento de conexões ortogonal (7) e conexões reta (8). Assim, com a troca das conexões (7 e 8) é possível com a mesma bomba (1 ) de diafragma atender a diferentes necessidades. Quando do acoplamento das conexões ortogonal (7) é possível utilizar a bomba (1 ) em pontos de tomada de entrada e saída de fluido desalinhados (A e B), como, por exemplo, no uso na parede de reservatório (13) de água rotomoldado como ilustrado na figura 10. Com essa disposição construtiva, na montagem da bomba (1 ) nos reservatórios (13), o acesso de entrada (4) do fluido permanece na lateral da base da câmara (5) que fica totalmente apoiada na superfície da parede, propiciando assim ótima sustentação e equilíbrio para operação de bombeamento na alavanca (3), independentemente da posição relativa do acesso de saída (6) do fluido. Por outro lado, quando do uso de conexões reta (8) é possível utilizar a bomba (1 ) em pontos de tomada de entrada e saída de fluido alinhados (C e D) como ilustrado na figura 1 1 . Dessa forma, ao instalar a bomba (1 ) usando a parede do reservatório (13) ou em base horizontal ou vertical com pontos de tomadas alinhados utilizando conexão ortogonal (7) ou reta (8) criam-se meios para que a mangueira (M) de condução do fluido seja posicionada sem dobras e / ou interrupções. More particularly, the novel diaphragm pump (2) is configured by a pumping chamber (5) having laterally an inlet port (4) aligned at 180 Q with an outlet port (6), both threaded accessions (R) for receiving and coupling orthogonal connections (7) and straight connections (8). Thus, by changing the connections (7 and 8) it is possible with the same diaphragm pump (1) to meet different needs. When coupling the orthogonal connections (7) it is possible to use the pump (1) at misaligned fluid inlet and outlet ports (A and B), such as for use in the water reservoir wall (13) With this constructive arrangement, when mounting the pump (1) in the reservoirs (13), the fluid inlet access (4) remains on the side of the chamber base (5) which is fully supported on the surface. thus providing optimum lift and balance for pumping operation on lever (3), regardless of the relative position of the fluid outlet port (6). On the other hand, when using straight fittings (8) it is possible to use the pump (1) at aligned fluid inlet and outlet outlet points (C and D) as illustrated in figure 1 1. Thus, when installing the pump (1) using the reservoir wall (13) or on a horizontal or vertical base with outlet points aligned using orthogonal (7) or straight (8) connection, means are created for the hose (M ) fluid conduction is positioned without bending and / or interruption.
[017] Acima da câmara de bombeamento (5), o diafragma (2) de contorno convexo é guarnecido por uma tampa (10) semiesférica removível em relação à borda (12) nervurada de fixação do referido diafragma (2) por meio de travas (1 1 ) cujas projeções negativas (14) tomam lugar em rebaixos (15) da referida borda (12) gerando um travamento não definitivo tipo dique (16) passível de remoção com relativa pela inserção de uma chave de fenda ou dispositivo afim na espera (17) perimetral também
localizada em dita tampa (10). Por fim, batoques (18) radiais na borda (12) nervurada concordantes com encaixes (19) na aba inferior da tampa (10) impedem o giro dessa última em relação a primeira peça, ou seja, em relação à borda (12) nervurada.
Above the pumping chamber (5), the convex contoured diaphragm (2) is provided with a removable semi-spherical cap (10) with respect to the ribbed edge (12) for securing said diaphragm (2) by means of latches. (11) whose negative projections (14) take place in recesses (15) of said edge (12) generating a non-definitive dike-like lock (16) which can be relieved by the insertion of a screwdriver or similar holding device (17) perimeter also located on said lid (10). Finally, radial bungs (18) on the ribbed edge (12) in accordance with fittings (19) on the lower flap of the cover (10) prevent the latter from pivoting with respect to the first piece, that is, relative to the ribbed edge (12) .
