Fan balancing. Impeller balancing.

[@jitendraitankar9722]

thanks a lot.. definitely helpful...live example helps in reinforcing the student's and working engineer's faith in theory

[@JahanZeb1976]

Thanks for appreciation. You are right, it would help many. Stay tuned and blessed.

[@stuzman52]

Much better video using your voice narration in the background. Nice work Jahan!

[@velbond007]

Ohhhh my god. No need class room no need to study... I have studied in papers about phase and all. But just only one time man watched this video and understood total balancing and using micto log too. Who are you?.? You are not only a reliability engineer, but trainer, interested to teach..... super. My thanks and best wishes to your all videos..... many thanks

[@vinodverma2344]

Dear sir, it is a good job

[@YuazaEthes]

Terima kasih sudah berbagi ilmunya..👍👍👍

[@mtrltoolman]

thank you jahan for sharing your knowledge.

[@juancarlosvilcapariona6119]

That's so interesting. Thanks you for share your experience.

[@mohamedbangura3713]

This Video makes lots of sense Thanks

[@zx8401ztv]

loverly job done :-)) Its hard to dub your own videos after the event has passed, trying to remember what you did exactly, but it was very clear and noise free in the room you were in :-)) So apart from the skf tool using the white line as an rpm pickup, it is also a timing pulse to start the capture of data for every revolution, and the maximum voltage of the vibration sensor can be tracked to a position after the synk point. So synk/strobe is 0 degrees and the speed is known then the rotation period can be calculated, the ratio of rotation period to vibration period point could be used to divide 360 degrees to tell you where it is. Sorry im rambling to myself while thinking out the basic idea lol.

[@JahanZeb1976]

As I said before you have rock knowledge. Your understanding to the matter is awesomely great! Yes you are correct it is a bit difficult to dub and re-assemble the events again after passed but it was necessary as it was very noisy there where I was filming in real situation. Also the camera in my hand was a poor quality one. But I am sure What I did, would be enough to give understanding to a person working on such a job.

[@zx8401ztv]

LearningZone There is nothing wrong with your video, the picture quality is plenty good enough to see what is happening, your commentry made everything clear :-) My knowledge is only basic, i also forget things over the years so its allways great to have the memory refreshed by your smashing videos :-)) Im one of those odd people that found learning from school or text books almost impossible, it made no sense to me, i needed to physically take things apart and learn from reality, just an odd sort of brain i suppose, thats me "Odd" ha ha :-))

[@navnitkumarsingh6884]

Wow great

[@kennydizon1713]

Wow great video very informative, thank you sir by the way I'm also performing balancing on my work here in the philippines, but I'd like to know how to balance using skf microlog skf😅

[@hainc3345]

Thanks for your video! Can you tell me the type of tachometer you used for balancing?

[@JahanZeb1976]

This is skf opto techometer or speed sensor. The type no I can't recall. You can verify it from skf website. Stay tuned

[@naveedahmad8131]

Appreciate your work,great job . sir please can you uplaod two plan balancing video .how to balance fibrizer or schreder .if there is raleted vidoe do you have or other raleted material ..please help me solving that problem...

[@صديالصورة-ظ1و]

If you put the trial weight at a 240° , you would reduce the vibration from the first time.

[@JahanZeb1976]

Yes sure. But nobody knows what will happen.

[@omarb1337]

Great video. Thanks

[@benkohkh]

When adding the weight, do you also consider the weight from the weldment?

[@JahanZeb1976]

Yes, it should be considered for small fans where you need a few grams of trial and correction weight. An estimation can do. For bigger fans where kgs of weight you need to balance, a few grams of welding wouldn't effect much.

[@mahadebdey4595]

how to calculate the weight of trial weight for the 1st time. will i attach any weight, or there is any calculation of trial weight by using impeller weight?

[@JahanZeb1976]

According to impeller weight there are mathematical calculation formulas available. But you can guess trial weight of any appropriate weight. It would work if don't cross the limits. Means don't go for big weight for a small impeller and for a big impeller a very small weight.

[@srikanthreddyvakidi8594]

I have one question, initially it has shown 60 deg. Why did it change to 173 deg even after we selected not to add trial weight

[@GENO89]

Hello! I liked your video tutorial! Please help more. With balancing fans! We have to work on the production of about 470 engines! I would like you to help me with a more detailed

[@ishwarprasad7803]

mast

[@JahanZeb1976]

Thanks.

[@sreejithnair4261]

After hours of futile surfing finally came to your video. All queries are now clear. Did you weld the trial weight . Didnt see you do it or grind it out later. Pls explain that

[@JahanZeb1976]

Sure welded the trial weight and then ground it also. This is a must step ln every balancing. Watch video again. Maybe I missed it. Or you would be missing it.

[@govindhakke6493]

Sir trial waight remooved or not after balancing

[@JahanZeb1976]

Trial weight removed during balancing after trial run and before fixing correction weight. Trial weight is just to make trial calculations by the balancing machine.

[@adityabimal1800]

Is dual channel analyzer sufficient for vibration analysis and balancing ? Can you suggest me which analyzer I should look for consultancy service ?

[@efraincastillogarcia6150]

The test weight you place counting in favor of the rotation rotation or against

[@JahanZeb1976]

+Efrain Castillo Garcia every weight, trial or test and correction, degree is counted opposite the direction of rotation. The test weigh one can fix anywhere of any grams size. The obvious angles are off course 0 and 180. The weight is estimation for small fan small weight and for big fan big weight. Hope you understand.

[@Rose-o1l3b]

amp. increasing when i apply correction weight on the counter rotation, is there a setting for that? There is a problem on my microlog but i don't know where...

[@JahanZeb1976]

+ffrosttt Dear friend there is a setting in the subject microlog while you are starting balancing or when you enter to the device setup screen. Just search it and it is stating whether you will apply balancing weights in the direction of rotation or opposite the direction of rotation. I am always keeping that setting in the opposite the direction of rotation not to put my self in error and to bring symmetry in work. Another thing is sometimes with the proper setup even you will encounter the problematic situation where you will not be able to overcome on vibration even with proper weight and proper angle. There are so many parameters in such situation. Your experience and skill is the key to solve such a problem in such difficult situation.

[@Rose-o1l3b]

+LearningZone thanks for quick reply, i'll look for setting, what are the parameters that effects balancing procedure? I tried and failed on a fan 1860 rpm, 32 mm/sn amp. with a huge motor, i did everthing just like written on the book but in the end ampitude increased, any quick advise for my case? Thanks again for the great videos and instructions...

[@JahanZeb1976]

+ffrosttt Dear friend if your fan is not responding to balancing, repeat clean balancing from begging. If you balance fans in routine and did many balancing jobs successfully in past with great results then there could be some other problem with the fan giving 1X vibration like looseness, bent shaft, bearing or any other possible reason. Check for every thing. If you are beginner in the field of balancing then check your procedure for any mistake. Sometimes we are making a mistake which are leading us to failure. Hope you will do it good. Share your results and success with us. Regards,

[@Rose-o1l3b]

+LearningZone I couldn't fine any settings for rotation on microlog. I'm applying weights on same direction as the impeller rotate, it works, amp. decreased all the time... :)

[@nishanthan5969]

check the blade type is it aerofoil blade or plate type blade

[@nishanthan5969]

sir am having one question that before adding correction weight u need to remove that trail weight sir ?

[@LastBlade]

You are right, you must remove the trial weight. But there are several instruments that provide the option of not removing trial weight. So the position of correction weight will be different. Trial weight should be removed

[@preetheshkumar227]

Sir, For 210Kg ,700 dia flywheel rotating for 4000 rpm , dynamic balance report says R1=0.49 grams,R2= 0.51 grams ,before it was R1=40 grams,R2=50grams and vibration value is less than 2.61 R1,R2 is it acceptable

[@ashwanisingh7741]

Sir phase angle shown in instrument is in direction of rotation or opposite direction of rotation. Please anyone tell me

[@JahanZeb1976]

This is the angle of heaviness. You will cound degrees opposite the direction rotation from your reference zero mark.

[@MrT79shakeshake]

Hi Learning zone can you tell me what laser tacho you are using please?

[@JahanZeb1976]

This is optical sensor from SKF. Anyhow if you are able to get one similar from some other supplier, get it for your work because SKF is for no reason very expensive and they are selling others products for very high cost.

[@eltongamer8473]

muito bom mais se fosse em português seria ótimo!

[@bouasriaabdelhamid4172]

please how do you calculate the trail weight

[@JahanZeb1976]

Trial weight is all your experience with fans. After little experience you know how much trial weight do you need for what size, kind and speed of motor. The you keep a record for particular fans around you. Hope you understood the idea. Stay tuned.

[@DeepuKumar-qh3pf]

Nice video sir but I have a question after trail weight to add correction weight is that add fan rotation direction ya opposite direction

[@JahanZeb1976]

Sure you will count degrees opposite the direction of rotation.

[@DeepuKumar-qh3pf]

Thank u sir

[@naveedahmad8131]

I have problem with two plan balancing please help me ...

[@jakealboroto9461]

hi sir I'm Jake great video This is so helpful for us to know since we have same instruments,, by the way i have a question about on your video of balancing did you remove the trial weight before you weld the correction weight i did not see on the vid.. thanks for the reply,,

[@JahanZeb1976]

Thanks for liking. Here I removed the trial weight after completing the trial run. There is option available in the machine to select if you don't want to remove the trial weight. But my preference is to remove it. Stay tuned and blessed.

[@jakealboroto9461]

thanks for reply sir ,,, hoping in the future to have more discussion with you since I'm using same instruments thank you again

[@adityabimal1800]

Hi # Jake Alboroto Can you share which equipment is this and also I would like to know weather 2 channel vibration analyzer is sufficient for balancing operation and for condition monitoring???

[@شعيبقحف]

Thank you men

[@srworkshop]

Sir price of this analyzer device

[@JahanZeb1976]

Very expensive. $50,000 with software and training.

[@srworkshop]

@@JahanZeb1976 36.50 lakhs in indian currency. Too much cost of this machine in india

[@JahanZeb1976]

Yes, it's very expensive.

[@JahanZeb1976]

velmurugan ezhumalai Thanks for your complement and great comment. I made the video as clear as I could do it. I would upload one more video on balancing and more videos on motor alignment. I already shot them and soon will upload them. Also will upload more on vibration analysis case studies. I am basically Electrical Engineer. I did work as Reliability Engineer. Now a days working both as Sr. Electrical Engineer and Reliability Engineer. That is great that you learned from my video and subscribed also. Regards and wish you good luck.

[@velbond007]

Is it possible to explain the SKF microlog analyzer full details from the software installation to create equipment hierachy into system and downloading into microlog as trat it as fresh, new piece, nothing inside. And after collecting data how to upload to system and watch the spectrum in computer monitor ? Pls. I have microlog in our company, but people does not want to teach...........

[@JahanZeb1976]

velmurugan ezhumalai Sure dear friend I have videos showing a lot of stuff among your questions. Only software installation is not covered as I didn't do it ever. I would upload the videos sequentially in future. Be in-touch. Regards,
