Daily maintenance and maintenance of drying oven

Drying box and vacuum drying box, the heating tube will accumulate high heat in a short period of time during use, so pay attention to the uniform dissipation of heat during use, that is, the blower must be turned on after heating. If it is turned on If there is no non-heating situation afterwards, first check whether the control instrument is working properly, that is, use a universal meter to measure whether its voltage is normal. If the instrument is normal, the drying oven and the vacuum drying oven, the heating tube will accumulate in a short time during use High heat, so pay attention to the uniform dissipation of heat during use, that is, you must turn on the blower after starting heating. If there is no non-heating situation after turning on the machine, first check whether the control instrument is working properly, that is, use The universal meter measures whether the voltage is normal. If the meter is normal, check whether there is resistance in the heating tube. The reason for the non-heating cannot be found after the second investigation, and then the parts can be replaced according to the reason.
