There are two situations, one is that foreign bodies are introduced into the motor, the other is that foreign bodies are introduced into the wind drum, which will lead to different results.
In addition, we also need to have a concept of foreign bodies, such as screw more various metal small pieces must be foreign bodies, but some large particles of things also count, such as the filter is not done well when vacuum, there will be many will be sucked into the wind drum, causing serious consequences.
There are foreign bodies in the motor of the side channel blower, which will cause the motor to burn down. Although the motor is insulated, the foreign bodies will be sucked into the line to buy when the motor is electrified. The foreign bodies will rub and rub, and the paint will be removed, which will lead to short-circuit burning. So where did these foreign bodies get in? The greatest possibility is that it leaks through the hole end under the wiring board on the motor, and there is no other place to go.
But the foreign matter in the side channel blower's blower can make the blade grind to the barrel and cover (suck in foreign matter or deform, processing is not good), bearing damage, and Laizhou is accompanied by noise, affecting the use of the situation. In serious cases, because of the foreign matter and high-speed friction of the blower, the phenomenon of wind blower being broken will occur, which is that the side channel blower has to be large. Repair, these are foreign bodies in the wind drum can not be reached, but also common.
