After prolonged operation of the fan, carbon has been produced between the rotor and the bearing, which hinders the normal operation of the rotor.
Now the fan motor is smoking, which means the windings are burned out and the motor needs to be replaced to fix the problem. It has nothing to do with the socket.
A wind turbine is an electrical device that converts wind energy into mechanical work, which causes the rotor to rotate and ultimately produces alternating current. Wind turbines generally consist of components such as a wind wheel, a generator (including devices), a steering (tail), a tower, a speed-limiting safety mechanism, and an energy storage device. The operating principle of a wind turbine is relatively simple. The wind rotor rotates under the influence of the wind. It converts the kinetic energy of the wind into the mechanical energy of the wind rotor shaft to generate. electricity. Generally speaking, wind energy is also solar energy, so we can also say that a wind turbine is a thermal energy generator that uses the sun as a heat source and the atmosphere as a heat fluid. work.
There are generally 4 situations
(1) The quality of the fuel used is poor
Due to the poor quality of the fuel used, the fuel entering the cylinder cannot be completely burned, causing black smoke. As long as qualified fuel is used, the fault can be eliminated.
(2) Damage to the fuel injector
Since the fuel injector has high pressure when injecting, if impurities are mixed with the fuel, Hard impurities can scratch the inner wall of the fuel injector, thereby changing the accuracy of fuel injection. Excess fuel cannot be completely burned ins the cylinder, which will also cause black smoke to be emitted from the exhaust pipe. At this point the fuel injector needs to be replaced.
(3) The air filter is clogged
Due to the dusty environment, a large amount of dust causes serious clogging of the air filter and enters the cylinder< /p>
p> There is a lack of combustion air and incomplete combustion of the fuel, resulting in black smoke. At this point, the air filter should be cleaned or replaced, and the environment should be cleaned to prevent such breakdowns from occurring.
(4) The engine injection timing is incorrect
The work of each engine cylinder is obtained by calibrating its injection time, i.e. say the work done by the piston< p>The process must correspond to fuel injection. If there is a time difference between the two, it will cause incomplete combustion and black smoke.At this point, it is necessary to adjust the engine injection timing and valve clearance to eliminate the fault.
