The cooling water system of early intermediate frequency heating equipment mainly used softened water, such as distilled water, added a radiator in the pool, and connected water pumps and pressure gauge pipes to meet the requirements of intermediate frequency heating equipment. The cooling water outlet of the equipment is exposed, making it easy to observe and check the temperature. Water tanks and pipes are often made of steel. Maintenance measures include regularly cleaning the water tank of impurities, or dividing the water tank into two compartments: one compartment is a sedimentation tank, connected to the return water pipe; the other is a clean tank, connected to the water pump suction port. The two grids are connected at the upper part, and the water in the sedimentation tank flows from the upper part to the clean tank.
This cooling water system has undergone major changes since the 1970s. Firstly, the visible discharge water contains air, which affects the cooling effect; secondly, the use of pipe fittings such as sinks and galvanized steel pipes made of steel materials can easily lead to the presence of iron oxide in the water. How to monitor the water inlet pipe filter before a fault occurs, such as clogging, requires corresponding monitoring instruments; and how to save industrial water in the heat exchanger is also one of the issues that must be considered to improve the system.
For the cooling system of medium frequency heating equipment, the following issues should be considered:
1) Water consumption and water pressure of the sensor
2) Water consumption of heat exchanger
3) The range of water temperature changes
4) Degree of liquid filtration
5) Liquid temperature rising time
6) Capacity of quenching tank
7) Allowed flow changes
