Le dispositif de pulvérisation de peinture pour l'usinage d'une pompe centrifuge comprend une chambre de pulvérisation de peinture (1) et un réservoir de stockage de matériau (3), un réservoir de collecte d'eau (2) étant relié de manière fixe à l'arrière de la chambre de pulvérisation de peinture (1) ; une première pompe à eau (4) est reliée de manière fixe à la partie supérieure du réservoir de stockage de matériau (3) ; une extrémité d'admission de liquide de la première pompe à eau (4) est en communication avec le réservoir de stockage de matériau (3) au moyen d'un tube d'aspiration de liquide ; une extrémité de sortie de liquide de la première pompe à eau (4) est en communication avec un tube coudé (6) ; une extrémité du tube coudé (6) s'étend dans la chambre de pulvérisation de peinture (1) et est en communication avec un tube télescopique (15) ; un moteur électrique (10) est relié de manière fixe à un côté droit de la chambre de pulvérisation de peinture (1) ; un arbre de fixation (12) est disposé transversalement et de manière rotative sur un côté gauche de la chambre de pulvérisation de peinture (1) ; l'arbre de fixation (12) et une extrémité de sortie du moteur électrique (10) s'étendent tous deux dans la chambre de pulvérisation de peinture (1) et sont respectivement reliés de manière fixe à une plaque de liaison verticale (11) ; un arbre creux (13) est disposé sur et est relié de manière fixe aux plaques de liaison verticales (11) ; le bas de l'arbre creux (13) est en communication avec une pluralité d'ensembles de buses de pulvérisation aptes à pulvériser de la peinture ; et la chambre de pulvérisation de peinture (1) est pourvue d'un mécanisme auxiliaire (17) apte à absorber un brouillard de peinture. Au moyen du dispositif de pulvérisation de peinture, des particules de peinture dans un brouillard de peinture sont commodément pulvérisées, déposées et filtrées étape par étape, évitant ainsi que la peinture ne soit directement évacuée sans aucun traitement.
