Some time ago, a customer's blower didn't turn, it stuck, and I couldn't get it, and I didn't know what caused it, because it wasn't very far from our company, so I agreed to come and look at it.

Just to have a little time today, I will explain this case, which can be regarded as a popular science. I hope everyone can try to avoid this situation from happening again when using it.

The next day, after arriving at the place where the customer's fan was used, I saw that the use environment was not very good, and that the customer's usage was used for blowing and suction, and it was recycled.

Moreover, the inside of the connecting pipe of the air inlet has already turned yellow. It was originally white, and now it is the same as rust. Seeing here, I do n’t think well. Basically, it can be qualitatively that the excessive dust accumulation causes the stuck.

The appearance of the fan is still very new, and there are no bumps. Check the motor with a tool, it is intact, and then use the tool to move the impeller and it will not move. So you can only disassemble the machine to see the internal reason.

After disassembly, as shown in the following figure: you can see that the interior is coated with something, and the outer edge of the impeller has obvious scratches. After removing the impeller, the same is true for the inner wall.

The other parts are intact, we just need to clean up these ash deposits, and some parts have been rubbed very hard, and can only be cleaned with the help of tools, such as brushed cloth.

The impeller, the pump body, and the pump head must be cleaned up. After the completion of the work, the blower returned to normal under the test operation. Pay attention to whether there is any abnormal sound at this time.

In view of this, a fan-specific filter can be installed at the air inlet, which can largely avoid this situation, and even if it cannot be avoided, it will extend the life of the fan.
