Abstract

numa bomba submersível multiestágio, um turbilhão prévio é gerado na entrada de líquido na bomba sem a adição de partes especiais. uma caixa com boca de sucção para uma bomba submersível multiestágio que manuseia um líquido agrega uma variedade de caixas que se distribuem ao longo de um eixo e estão espaçados de maneira circunferencial ao redor do eixo. uma variedade de bocas de sucção está disposta ao longo da direção circunferencial por intervalos entre a variedade de caixas. na seção transversa ortogonal ao eixo, a variedade de bocas de sucção está em uma direção diferente à direção na qual o líquido transpassa em cada uma das várias bocas de sucção que se direcionam ao eixo, podendo também a direção de entrada do líquido em cada uma das várias bocas de sucção ser variada. a direção na qual o líquido transpassa em uma das bocas de sucção é formada de modo a ser girada por um ângulo predeterminado em torno do eixo.in a multistage submersible pump, a previous vortex is generated when liquid enters the pump without the addition of special parts. a suction nozzle box for a multi-stage submersible pump that handles a liquid adds a variety of boxes that are distributed along an axis and are circumferentially spaced around the axis. a variety of suction nozzles are arranged along the circumferential direction at intervals between the variety of boxes. in the cross-section orthogonal to the axis, the variety of suction nozzles is in a different direction to the direction in which the liquid passes through each of the various suction nozzles that are directed towards the axis, and the direction of liquid inlet in each one can also. of the various suction nozzles to be varied. the direction in which the liquid passes through one of the suction nozzles is formed so as to be rotated by a predetermined angle around the axis.
