This article mainly introduces induction heating machine cooling water system abnormal solution as follows:

　　First, dust and grease

　　We operate high-frequency quenching equipment in the environment may have the appearance of fine particles, such as: water vapor, dust, grease and so on.

　　1, inhaled from the gap

　　Because of the exhaust fan installed inside the induction heating machine mainframe, the equipment will breathe these fine particles from the gap during operation.

　　2、Insulation and heat dissipation

　　(1) When it encounters high voltage, it will pull arc or fire, and if the degree is serious, it will lead to combustion, reason: the insulation of the device will be damaged;

　　(2) Attached to the printed board, electrical components, and the surface of the mounting wires, which will result in poor heat dissipation of parts or components.

　Second, no emergency water supply system

　　System does not have emergency water supply system, high-frequency quenching equipment in normal operation, if the sudden water outage, even if the host has a working protection, but because the heating furnace body due to the high temperature of the furnace chamber and high temperature workpiece, it is difficult to achieve the effect of cooling within a short period of time, so that it is easy to damage the furnace body.

　　Third, unstable water pressure

　　Jinda small editor suggests that you use the power supply, please design the water circuit according to the requirements. Because the high-frequency quenching equipment, water pressure loading range is generally: 0.2 ~ 0.3MPa. But we will often appear in the use of equipment, water pressure is too low or too high phenomenon, thus causing adverse effects on the equipment.

　　1, the water pressure is too low, will cause damage to the IGBT or other components, cause: poor heat dissipation.

　　2, the water pressure is too high, threatening the induction heating machine circuit, cause: burst or drip.
