A: This question asks about the quality of the fan, due to the varying manufacturing quality of various manufacturers, which can produce different lengths of service life, even if the continuous operation of tens of thousands of hours is normal.
40 years old fan
The reasonable winding of the coil, the quality of the capacitor, the quality of the silicon steel sheet, the precision and lubrication of the bearings, the motor's rotational speed grade, and so on, these conditions determine the life of the fan.
My family heirloom a fan, because every year to add lubricant, has been used for 40 years without bad, my home bath room fan was a child accidentally open, turn half a year without stopping, I help colleagues repair fan, because the quality of the coil and leakage of magnetism, only one year of use that does not turn,
by the use of the fan is not bad, we must adhere to the oil holes every year to drop a few milliliters of oil to ensure that lubrication that will be able to withstand the use of the fan!
Thank you!
I remember a long time ago that there is a "Golden Dragon" brand fan, his manufacturer has a fan in the laboratory, continuous rotation for 12 years, may be advertising it? But it also shows that this thing if the quality meets the requirements, generally not bad.
In the last century, Nanjing Xinbai a window, an electric fan has been turning, the impression has been turning at least three years, it should be advertising.
It's hard to say how long it's been on, but the chances of it going bad are greater. How long it takes to see the quality, and then there's the power outage.
In the absence of a "timer" switch, the fan will keep going. The fan will keep going until one day when the host heats up and burns out before it stops rotating.
The next morning, mom will help you stop.
The amount of time an electric fan can safely work continuously is not the same depending on its quality. I haven't tested and don't want to test the current fans because the quality is not as good as the older brands. I used to have two floor fans in my house, and one table fan, which was a Three Gorges brand. [teeth bared] Are there any that are of the same brand as the ones I use at home?
Once in the summer to go to the floor fan forgot to close, continuous non-stop open nearly 500 hours until last year when the scrap sold, sold when still can be used normally, has been used for 34 years. The two Three Gorges fans are still in the house.
Previously, I have seen reports that the manufacturer in order to test its service life, once without stopping to open a full 2 years, and then stop to measure the wear of its shaft, still within the allowable range. The main thing with fan motors is to grease the bearings over time, they will last longer.
I now do the home appliance industry, I say honestly now the electric fan whether the United States or Emmett or Wanbao and so on other brands, ninety percent of the fan motor is copper-clad aluminum.
I have encountered the sale of the cow horn industrial fan pet store in the summer, only less than a week of work, continuous open time is not more than 30 hours, the motor burned out. After replacing the motor was not used for a long time, the lack of heat dissipation led to the motor burned out, the back of the pet store to come back to buy a two rotating use before there has been no problem. Now the quality of the electric fan is not as good as before.
It's been constantly powered, and if the bearings aren't bad, it should be able to keep turning. The bearing life should be up to 100,000 hours.
The fan can be turned on for 1 hour unless the power is out or it is broken!
It's a retarded thing to do! Definitely you wa dial off the power plug ！！！！ There is also the meter inside the electricity cost is finished ！！！！ Mo got things, less idle talk about the egg egg pain ！！！！！.
