Description

Technical Field

[0001] This utility model relates to the field of industrial design technology, specifically a water replenishment mechanism based on a generator stator cooling water tank. Background Technology

[0002] The generator stator coolant tank is an important component of a generator set. Its main function is to store and supply coolant to the generator stator for cooling. During generator operation, the stator generates a large amount of heat, which needs to be dissipated by the coolant to ensure the normal operation of the generator.

[0003] The existing cooling water, during long-term operation of the equipment, cannot meet the pH requirements of the power industry. The pH value is kept in a low range for a long time, which will cause copper corrosion. When the copper ion concentration in the cooling water reaches a certain level, copper compounds will precipitate. This can affect heat transfer, or even block the water flow channels of the copper wire rods, affecting the normal use of the equipment and thus having limitations.

[0004] The reason for this problem is that the pH value of the stator cooling water is maintained at a low range for a long time, which causes severe corrosion to the copper materials in the generator stator coils. Furthermore, when the copper ion concentration reaches a certain level, they undergo a chemical reaction in the stator cooling water, forming various copper compounds. These copper compounds begin to precipitate after reaching a certain saturation point in the water. These precipitated copper compounds can, at best, adhere to heat transfer surfaces, affecting the heat transfer efficiency of the stator cooling water and thus reducing the generator's cooling effect; at worst, they can directly block the water flow channels of the copper wire rods, preventing the stator cooling water from flowing smoothly, thus affecting the normal operation of the generator and even causing serious safety accidents. Therefore, we propose a water replenishment mechanism based on the generator stator cooling water tank to solve the above problems. Utility Model Content

When the pH value is kept at a low range for a long time, copper corrosion will occur. When the copper ion concentration in the stator cooling water reaches a certain level, copper compounds will precipitate, which may affect heat transfer or even block the water flow channels of the copper wire rod, affecting the normal use of the device and thus having limitations.
