What are the requirements for cooling water for intermediate frequency heating equipment?

1. The induction coils, water-cooled cables, reactors and capacitor banks of the intermediate frequency heating equipment are cooled by industrial pressure water. The cooling water pressure should be kept at 0.15-0.20Mpa, the water temperature should be kept at the inlet water temperature of 20-35°C, and the outlet water temperature below 55°C. If the cooling water temperature is too low, condensation will occur, and if the water temperature exceeds 55°C, the cooling capacity will be lost. In order to save water, a circulating cooling system can be used.

2. The cooling system of the thyristor inverter of the intermediate frequency heating equipment should meet the following conditions: the cooling water pressure should be stably maintained at 0.15Mpa, the water quality should be softened, the hardness should be less than P8, the resistance should be above 20kΩ, and the water should not dissolve The substance is less than 0.03mg/L.

In order to ensure the safe use of intermediate frequency heating equipment, the cooling water system should implement centralized water supply and return water, and the waterway should be equipped with a water pressure alarm device and a water stop warning device to prevent equipment accidents caused by insufficient water pressure or water cut off.
