Troubleshooting 1: Abnormal sound or loud noise during operation.
Factor analysis and treatment: improper installation makes the fan blades loose, causing abnormal sound when touching the air guide frame, and the fan blades are installed accurately and tightly from the beginning; The bearing of the motor is badly worn, so it is necessary to replace the bearing of the same model; If the motor device is defective, check the gap between the stator and rotor of the motor to make it even. If there is axial movement, add a suitable washer; Blade deformation is unbalanced, check the blade and adjust the dynamic and static balance of the blade; The air outlet pipeline planning is unreasonable. Turn the air outlet pipe as little as possible, turn it big and round.
Troubleshooting 2: The range hood swings too much.
Factor analysis and treatment: if the fixation is not firm or the device is not good, add rubber pad or foam plastic to make the fixation firm; There are foreign bodies on the blades, and the dirt inside is too thick. Remove foreign bodies and internal dirt on the blades; The spindle and the cutter sleeve are eccentric, and the spindle and the cutter sleeve are adjusted from the beginning to be concentric; If the motor bearing is worn or the bearing hole is too large, replace it with a new bearing of the same specification; The motor winding is partially short-circuited or open-circuited. Replace the winding or motor.
Fault repair 3: poor smoke exhaust effect
Factor analysis and treatment: the installation point is too high from the cooker, so the installation point should be lowered appropriately; If the exhaust pipe is too long or the outlet direction is not chosen properly, shorten the exhaust pipe appropriately and choose the outlet direction from the beginning; If the sealing strip fails and leaks, replace the sealing strip to seal it tightly; If the internal circulating activated carbon fails, replace it; The pressure difference inside and outside the room is too large. Open the doors and windows appropriately to reduce the pressure difference inside and outside the room. If the voltage is too low, equipped with voltage regulator if necessary; The air intake passage is blocked by oil pollution, and the oil pollution is cleaned up.

I dreamed that the smoking machine was broken and the smoke was heavy. Hello:
It's just a dream, Conan. Dreams are false, don't take them seriously.
There is a book called Duke of Zhou, which mentions that dreams and reality are often opposite, which means that it can't happen in real life.
I think it's just that I accidentally pressed my arm to my chest when I was sleeping, which pressed my heart, and then the lack of blood supply to my brain led to brain activity, which is often called dreaming.
Scientific research shows that dreams are visual activities caused by all kinds of * * * inside and outside the body or the outside world left in the brain during sleep.
In other words, dreams have no meaning, no meaning, and are not a sign.
At best, it only means that you didn't have a good rest last night, which means that you didn't sleep well as the saying goes.
Maybe, I just woke up during the day and left a memory in my mind.
Yes!
A word for you: live today, tomorrow will be better.
I hope I can help you and have a good day.

There is a smoke machine on the roof of my house, which is too noisy. How to check the range hood? Take down the exhaust pipe first and see if there is any improvement. There are generally two aspects to the noise of the range hood, one is the range hood itself, and the other is the noise caused by poor smoke exhaust. Open the strong gear of the range hood and gently place it on the edge of the range hood shell with your fingers. If the vibration is large, it is the noise caused by poor dynamic balance. There are many kinds of poor ventilation in flue. The most common thing is that the flue is too narrow, and the exhaust air volume of large-displacement smoke machines is generally around 13 cubic meters/minute. Too narrow flue will cause exhaust obstruction, air flow turning around, and noise caused by increased wind pressure. There is also a need to check whether the exhaust pipe goes too deep into the flue, clings to the wall and blocks the flue. Another situation is that the installer is negligent and tightens the check plate when fixing the smoke pipe.
