The use of blowers has brought a lot of help to people's lives, but in some lives, it may burn out. What causes this? Many people don't understand this very well. Let's (high-pressure blower manufacturer) analyze the possible reasons for you.
1. Loss of phase operation: stable quality, vortex fan The motor coil burns unevenly, and burns black or scorched section by section. That is, the polar phase winding at the end of the winding burns black or turns dark brown, while the remaining two-phase windings are undamaged or slightly burnt, that is, the burnt condition is blackened diagonally in knots, rather than one circle. Circle. In fact, there are many reasons for the lack of phase operation of the vortex fan. The connection between the cable and the lead wire is not good and one phase is blown, the power fuse is blown, and the strength of the cable lug must not be cracked or equal. The lack of phase operation current is greater than the rated current. Motor windings will be burned due to overheating if they are not maintained.
2. Turn-to-turn short circuit: at the end of the vortex fan coil, it can be clearly seen that there are several turns or one circle or one pole phase group burnt, this part of the electromagnetic wire is often burned into bare copper wire, and the inner side of the short circuit part Or other two-phase coils are relatively intact or slightly burnt, usually because of wiring problems or long-term overload operation of the vortex fan, which causes the motor to burn.
3. Interphase short circuit: Interphase short circuit occurs at the end of the winding, and the insulation gasket between the ends of the winding has low strength or damage. When the vortex fan motor is heated or damp, the insulation of these thin places decreases, and then breaks down to form an interphase short circuit. There have also been cases where the connecting bushings of the vortex fan bridge wires are not handled properly or burned due to heat, and the bridge wires collide with each other to form a short circuit.
4. Other reasons: For example, the vortex fan sucks in impurities and foreign matter, which causes the motor to jam, and the operation is not smooth, to cause the motor to burn. If the impurities are conductive and fall into the motor, it will cause the motor to short circuit and burn. Some fans are overloaded or the air inlet and outlet are blocked and the main line of the motor is burned out, which causes the motor to fail to operate normally. Therefore, the air inlet and outlet of the vortex fan must be kept unobstructed during use.
The above are the possible reasons why the blower burned out by us (the manufacturer of high pressure blower), and I hope it can help you. When you use it, you should pay more attention to the above points to prevent the blower from burning.
