    • A robotic paint applicator having a plurality of relatively movable housing enclosures each including an explosion proof motor including a housing having a gas inlet and outlet, and a source of non-combustible gas under pressure connected to each motor housing inlet circulating non-combustible gas through the motor housing and directing non-combustible gas into the robot housing enclosures. The robot housing enclosures are substantially air-tight and interconnected with a control unit operating an inlet valve to maintain a predetermined pressure of non-combustible gas within each robot housing enclosure. The method of this invention includes purging the motor housings and robot enclosures at a first pressure and maintaining a lesser pressure of non-combustible gas following purging.
    • 一种具有多个相对可移动的壳体外壳的机器人涂料涂料器,每个壳体包括防爆马达,该防爆马达包括具有气体入口和出口的壳体,以及连接到每个马达壳体入口的不可燃气体源,循环不可燃气体通过 电动机壳体并将不可燃气体引导到机器人壳体外壳中。 机器人外壳外壳基本上是气密的,并与控制单元相互连接,控制单元操作入口阀,以保持每个机器人外壳内的不可燃气体的预定压力。 本发明的方法包括在第一压力下清洗电动机壳体和机器人机壳,并且在清洗之后保持不可燃气体的较小压力。
