There are several cases of overheating of the water-type mold temperature machine:
1, the thermostat problem. The mold temperature controller outputs the signal through the thermostat and controls the operation of the electric heating tube. If there is a problem with the thermostat, when the temperature reaches the set value, the thermostat will not send a signal, stop the heating of the electric heating tube, the temperature will always rise, and an over-temperature phenomenon will occur.
2. Another possible situation is that the temperature-controlled device belongs to an exothermic process, the power of the mold temperature cooler is too small, and the cooling capacity is less than the heat absorption of the heat-conducting medium in the temperature-controlled device, resulting in the temperature of the heat-conducting medium. Too high, but not falling down.
3. The solenoid valve (or other control valve) that controls the cooling water is burnt out. It is always in the closed state. When cooling is required, the cooling water cannot enter, causing the temperature to be too high.
