充油式电动机在潜入泵(潜水、潜油、潜卤)、潜艇及深井钻机上已广泛应用。在海洋石油开发工程和特殊水质场合,也有很大发展前途。这种内部充油电机采用机械密封,使外部介质难于侵入电机内部,使绝缘较可靠,轴承润滑良好,电机内部零件不易锈蚀,故适用于特殊工作环境。今就充油式潜水电机设计中的一些问题,进行探讨,以确保产品能可靠运行。 Oil-filled motor submerged pump (diving, submersible oil, submarine halogen), submarines and deep well drilling rig has been widely used. In offshore oil development projects and special water quality occasions, there are great prospects for development. This internal oil-filled motor with mechanical seal, so that the external medium is difficult to invade the motor, so that the insulation is more reliable, good lubrication of the bearing, motor internal parts are not easy to rust, it is suitable for special working environment. Now on the design of oil-filled submersible motor some of the issues discussed to ensure that products can operate reliably.
