How to solve the overheating of bentonite dryer motor

When working at high temperature and high intensity for a long time, the dryer motor is prone to overheating and burning the cable, causing a short circuit fault. In this case, the drying device will not work properly.

The bentonite dryer motor is the power source of the drying system of the drying device, maintaining the normal operation of the drying device cylinder. If the bentonite dryer motor has a short circuit fault, it will be a very difficult problem. There are two situations:

1. When the working current is 1.3 times the rated voltage, when the motor output becomes lower, the speed ratio of the dryer cylinder decreases, and the heat transfer speed regulator changes greatly in the low-speed state. As a result, all the drying occurs. The deviation of the equipment transformer is large.

2. If the working voltage is the rated voltage, the working frequency of the bentonite dryer will be too low, the working current will become unstable, and there will be jitters before and after, which will damage the transformer and ammeter of the dryer.

Taking the above into consideration, the heat transfer rate regulating valve of the bentonite dryer can be closed first to increase the working power. Subsequent restarts of the clay dryer can reduce the excitation working current of the motor and increase the speed ratio of the desiccant barrel when the initial conditions appear.

In fact, the problem of the bentonite dryer motor is a commonplace topic, but it cannot be ignored, so it is necessary to carefully check whether the motor will heat up or short-circuit during operation. And other problems. Find an expert. The technician will implement a solution.
