A circulating pipe is connected between a cooling cylinder sleeve used for cooling high-temperature water and inside the marine generator and the high-temperature water pump, so that the high-temperature water in the high-temperature water pump is mixed with low-temperature water in the cooling cylinder sleeve, and is mixed with an internal low-temperature water system to control the temperature of the high-temperature water and reduce the internal temperature of the generator. Generally, the temperature of the high-temperature water inside the generator is controlled at 85 ℃.
Since the temperature of the high-temperature water inside the generator is too high, air bubbles may be generated in the high-temperature water system.

However, when the generator is operated for a long time, because the water in the ventilation pipe is not separated from the water in the low-temperature expansion water tank, the heat of the water in the ventilation pipe or the heat carried by the bubbles introduced into the low-temperature expansion water tank can be transferred to the low-temperature expansion water tank, so that the low-temperature expansion water tank is in a high-temperature condition. And if the design of the throttling orifice plate of the generator breathable outlet is unreasonable, the pressure of the generator breathable outlet is too high, high-temperature water in the internal circulating pipe of the generator can flow to the low-temperature expansion water tank through the breathable pipe, the water temperature in the low-temperature expansion water tank can be further increased, and the high-temperature condition of the low-temperature expansion water tank is caused.
