How to deal with the burnt motor of the sawdust dryer
The emergence of sawdust dryer equipment has rapidly increased the value of wood processing and utilization, providing great convenience for the development of industry. But there are also safety hazards involved. The important thing is that once the motor of the sawdust dryer is burned out, the equipment will stop running, and the motor is the main electrical power to maintain the operation of the sawdust dryer. The damage to the motor can cause extremely inconvenient maintenance issues to the overall operation process of the sawdust dryer. So we need to carry out timely motor maintenance, preferably to fundamentally solve such problems.
Different models of small sawdust and sawdust dryers have different motor usage standards. Generally, before the dryer motor is turned on, we need to measure the size of the resistance
After the machine stops running for a period of time, it is more prone to moisture. At this time, the insulation between turns, the insulation paint itself, has low mechanical strength and is easily damaged after vibration. After the damaged insulation paint becomes damp, its insulation performance greatly decreases. At this time, even when encountering very low voltage, it can cause discharge, causing insulation material breakdown, and then forming a short circuit between turns, causing the motor to burn out. We can see that the reason for the motor burning is that we do not provide enough protection for the motor, and there may be a problem with the quality of the motor itself. What should we do when the motor burns out? Here we will provide you with a detailed explanation in three steps:
Firstly, we can conduct a temperature rise test on the burnt out motor iron core. If the test requirements are not met, the iron core can be disassembled and repainted with insulation paint. At the same time, attention should be paid to checking whether the iron core is loose. If there is any looseness, tightening measures must be taken.
Secondly, when threading and painting the iron core of the motor, it should be strictly carried out in accordance with the process requirements. When winding, it is advisable to use gauze wrapped wire shaping coils to strengthen inter turn insulation and avoid cross turns generating high potential between turns.
Thirdly, after the sawdust dryer is repaired, installation work begins. When installing the sawdust dryer, calibration and adjustment should be carried out. If abnormal motor vibration is found during operation, the cause should be promptly identified and dealt with. Avoid damage caused by excessive vibration of the insulation, which may eventually cause the motor to burn out again.
