1. Inspection Microwave drying equipment Cooling device of

When checking the cooling device, the cooling method used by the equipment shall be defined first. If water cooling is used, check the water pipe for water leakage and blockage. During air cooling, check whether the fan is in good condition and whether the fan power supply is normal, and replace the damaged parts.

2. Check the high-voltage capacitance of microwave drying equipment

The parallel resistance of high-voltage capacitor is about 10 Ω; The resistance between capacitor terminal and shell shall be infinite. If the measured value of the replaced part is inconsistent with the actual value.

3. Check the high-pressure silicon stack of the microwave drying equipment

Use a multimeter to measure the forward resistance of the high-voltage silicon stack, which should be about 100k Ω, and the reverse resistance should be infinite. If the actual measured value is inconsistent with the above data, replace the high-voltage silicon stack.
