At present, cooling water is basically used as cooling medium in Induction heating machine, and if the quality of cooling water is too low, the induction heating equipment may cause failure due to cooling medium, which may affect the production efficiency.
The water supply quality and water source target of cooling water should meet the following requirements:
1, the hardness of water is lower than 0.17 mg / L
2, the impurity content of water is less than 17 mg / L
3, the electrical resistance of water is not less than 4K Ω / cm;
4, the pressure of water supply, the main pipeline should be controlled at 0.2 m / 0.3 MPA.
Water contains too much miscellaneous mass, in capacitors, transformers secondary, primary cooling lines, will form scale. Especially at the pipe joint and elbow, it is easier to form a scale infarction pipeline. And then affect the cooling of components, damage power components.
Too many impurities and too high hard crossing in water mean that the resistance of water is lower. The leakage current of rubber or polyethylene pipe increases with the decrease of impedance voltage of water pipe. Therefore, the loss power is also increased, which is easy to occur water pipe to the ground discharge breakdown or water pipe heating, slow down the aging of the water pipe, make the water pipe crack, leakage, fault, affecting the operation of the equipment.
