Abstract
The utility model pertains to a water resistance box with a floating movable gas cup that is used in an electrohydraulic circulating cooling system of a water resistance starting speed controller of a winding asynchronous motor, mainly solving the problem that when the mouth of the pipe for liquid suction of the water resistance box is excessively high or low, the normal operation of the water resistance starting speed controller is hindered due to the resection of the water resistance caused by the overheating of the electro hydraulic. The utility model is characterized in that the floating movable gas cup is positioned in the water resistance box. Since the floating movable gas cup is closely contacted with the surface of the electro hydraulic and rises and falls in accordance with the surface, even if the mouth of the pipe for liquid suction of the water resistance box is comparatively high, the surface does not generate a swirl, thereby avoiding pressure decreasing and idle motion caused by the inhaling, and the temperature of the electro hydraulic is not excessively high as the electro hydraulic does not take part in the circulation cooling. Meanwhile, when the electro hydraulic at the top of the water resistance completely and fully takes part in the circulation cooling, the resection of the water resistance caused by the excessively high temperature of the electro hydraulic can also be avoided, thereby ensuring the normal operation of the water resistance starting speed controller.
