Electric Air Pump Repaired
On arrival of one desktop Computer for repair to my place I found the computer is full of dust. I take out my Electric Air blower pump which I use for blow the dust. but it was not working so here my priority is to make the tool in working condition.
After primary physical visual inspection, I checked power plug for some resistance but it didn’t show any reading on the Multimeter it indicates some open circuit hence I open the unit for inspecting it from inside.
So opened top cover using flat screw driver.
Then using screwdriver, I flipped up the fan blade. Found screw underneath.
Took apart the unit for further inspection.
After opening the unit on visual inspection nothing seems doubtful. Checked On/Off switch found OK.
Then checked continuity of power cable not getting any continuity on both the line & neutral cable. From the two pin plug on power cord to the switch.
It indicates both wires are open circuit. so removed the cable on removal I found internal cores of cable is brittle and it easily getting brake on little pulling. wire is totally degraded from inside. So replaced the wire.
Connected the fan blade on motor shaft & powered On the motor & motor starts normally.
Here I made one mistake I fitted Fan Blade wrong way which I was not realize because air flow seems ok & packed the unit & finished my job of Computer Cleaning……. I realized the mistake while I was preparing this article.
But I made it right as per Company Fitting ……

Erik,
Thanks for your input.....NO it is not correct , it was my mistake which i made right afterwards when i realize ....this is already mentioned in end of the article.
if you put Blade Upside down it will blow the air initially;but unit will get hot in few minutes, because it will not suck the air properly to blow.

good job on the repair. finding a faulty power cable is kind of nice. last week I was working on a vaccum cleaner and the cord was the problem so I could relate to that. thanks for sharing and have a blessed day
