Title
(EN) MOBILE SURFACE MAINTENANCE MACHINE WITH AN ONBOARD PRESSURE WASHER
(FR) MACHINE DE MAINTENANCE DE SURFACE MOBILE AVEC UNE RONDELLE DE PRESSION EMBARQUÉE
Abstract
(EN)
A mobile surface maintenance machine embodiment includes a mobile body, a solution tank for containing a cleaning fluid, wheels for supporting the mobile body, a maintenance tool(s), an output channel, an electric power source, a first electric motor, and a pressure washer. The pressure washer includes a spray wand, a pressure pump, and a second electric motor. The pressure pump is fluidly coupled to the spray wand and to the solution tank. The pressure pump is configured to pressurize the cleaning fluid supplied to the spray wand. The second electric motor is operatively coupled to and configured to drive the pressure pump. The second electric motor is configured to receive electric power from the electric power source and is commonly powered by the electric power source that provides power to the first electric motor. The second electric motor is separate from the first electric motor.
(FR)
La présente invention concerne, selon un mode de réalisation, une machine de maintenance de surface mobile qui comprend un corps mobile, un réservoir de solution pour contenir un fluide de nettoyage, des roues pour supporter le corps mobile, un ou des outils de maintenance, un canal de sortie, une source d'alimentation électrique, un premier moteur électrique et une rondelle de pression. La rondelle de pression comprend une lance de pulvérisation, une pompe à pression et un second moteur électrique. La pompe de pression est couplée fluidiquement à la lance de pulvérisation et au réservoir de solution. La pompe de pression est configurée pour mettre sous pression le fluide de nettoyage fourni à la lance de pulvérisation. Le second moteur électrique est fonctionnellement couplé à la pompe à pression et configuré pour entraîner la pompe à pression. Le second moteur électrique est configuré pour recevoir de l'énergie électrique à partir de la source d'alimentation électrique et est généralement alimenté par la source d'alimentation électrique qui fournit de l'énergie électrique au premier moteur électrique. Le second moteur électrique est séparé du premier moteur électrique.
