The problem of motor dampness is a major problem in enterprises in many coastal cities, or in enterprises in humid working environments. Air humidity is high, many motors are not sealed, so the probability of damp is very high, so how to prevent damp motor, found that the motor should be done after damp, today we will discuss with you.
In the actual production of many enterprises, some motors are placed for a period of time, and when they are re-started, it is found that the insulation resistance of motor windings decreases, and sometimes the insulation breakdown of motor coils occurs. This is the manifestation of dampness of motors. Damage to machines, if not to mention, is also a brief safety accident.
Especially in the rainy season, the humidity of the air is very high, which makes the motor moist. If the moist motor is put into operation without treatment, it will be extremely simple to have problems.
So what kind of urgent treatment should be carried out after the motor is damped, so that the motor can be put into normal operation from scratch? At this time, monotonic treatment should be carried out to make the insulation resistance and absorption ratio reach the prescribed value.
In fact, the monotonous treatment of motor is very simple. The external heat source heating method, preferably the special motor drying oven, is monotonous. This method is easy to operate, safe and reliable. Another way is to remove the damped motor first, and then bake it with a high-power incandescent bulb inside the motor, but it is only suitable for small motors which are easy to disassemble and inspect.
For large and medium-sized or non-disassembly-prone motors, the workload is relatively large and the feasibility is also reduced. It should be noted that the bulb or heat source should not be too close to the coil in order to prevent the coil from burning out. When heated together, canvas and other items can be covered on the motor shell for insulation, so that water can be transpired faster to reach the intention of the monotonous motor.
In fact, the common problems of motor damp right and wrong, the reason is that many enterprises do not have the concept of unprepared, if the motor has been operating, the probability of damp is very small, because the motor itself in the operation of heat, play a monotonous effect.
However, many enterprises do not often operate the motor, and some may only open once a month, so for this kind of uncommon motor, it is necessary to adopt a monotonous protection method in unnecessary time. To ensure that the motor reduces the possibility of dampness and reduces the risk of operation.
