Abstract
"PISTOLA DE PULVERIZAçãO COM TAXA DE PULSOS DE ALTA FREQuêNCIA E ALTA PRODUTIVIDADE". Uma pistola de detonação para pulverização térmica formada por uma câmara de combustão (1) e um cano (2), com entradas para combustível (5) e oxidante (4), uma ou mais velas de ignição (6), para detonar a mistura combustível-oxidante e um ou mais injetores (7) para a introdução do produto no cano, a pistola da invenção centralizando as suas características na incorporação de um sistema de injeção direta do gás combustível e do gás oxidante na câmara de explosão produzindo misturas explosivas de composições diferentes de acordo com as várias zonas da câmara de explosão, existindo um volume restrito nesta câmara de explosão no qual apenas combustível é injetado de tal maneira que ele possa gerar explosões de alta energia, mantendo a operação cíclica da pistola. A pistola também incorpora no cano (2-2') um ou mais injetores anulares (7), que permitem a alimentação de vários produtos e, especialmente, pó de revestimento de modo que seja possível aumentar o número de quilogramas depositados no substrato por unidade de tempo e, em conseq³ência, a produtividade da pistola."SPRAY GUN WITH HIGH FREQUENCY AND HIGH PRODUCTIVITY PULSE RATE". A detonation gun for thermal spraying formed by a combustion chamber (1) and a pipe (2), with inlets for fuel (5) and oxidizer (4), one or more spark plugs (6), to detonate the mixture fuel-oxidizer and one or more injectors (7) for introducing the product into the pipe, the pistol of the invention centralizing its characteristics in the incorporation of a direct injection system of the combustible gas and the oxidizing gas in the explosion chamber producing explosive mixtures of different compositions according to the various zones of the explosion chamber, with a restricted volume in this explosion chamber in which only fuel is injected in such a way that it can generate high energy explosions, maintaining the pistol's cyclical operation. The pistol also incorporates in the barrel (2-2 ') one or more annular injectors (7), which allow the feeding of various products and, in particular, coating powder so that it is possible to increase the number of kilograms deposited on the substrate per unit time and, as a result, gun productivity.
