机床常用AB型和AOB型电泵作为冷却系统的原动力。使用中,电泵电机常因冷却液浸入而被烧毁,致使机床被迫停工。冷却液浸入电机内的主要途径,除了由于液体飞溅从电泵电机的接线盒处渗入外,主要由电泵轴带着叶轮在液体中高速转动时液体沿着轴向衍渗,通过轴承进入电机内的。解决电泵电机浸水的方法:(1)在泵轴的上、下两端各装上一个橡皮
Machine tools commonly used AB-type and AOB type electric pump as the driving force of the cooling system. In use, the electric pump motor is often burned due to immersion of the coolant, resulting in the machine being forced to stop working. The main way that the coolant is immersed in the motor, except that the liquid penetrates into the junction box of the pump motor due to the liquid splashing, mainly flows along the axial direction when the impeller rotates with the impeller in the liquid at high speed and enters the motor through the bearing inside. Solve the pump motor water immersion method: (1) in the shaft, the lower end of each fitted with a rubber
