08/08/2017 6:26 AM

Hello everyone,

I just need to ask you about proper storage procedure for shafts in warehouse?

Can anyone share their experiences with photogrphs

Thanks

I mean shafts of centrifugal pumps especially long shafts of vertical submersible pumps

Abhishek, You need to provide following information:-

1, size, weight , qutty, of the shafts to be stored.

2.Wether it is manually handled or mechanized.

3.No. of storage and retrievals per shift.

Sir,

I am generally having shafts of 30-35 mm dia and length upto 1.5 m , i just want to confirm whether vertical storage will be helpful or horizontal storage as i have read that in horizontal storage shafts develops run out in due course hence vertical is recommended but can not find any document/photographs/article supporting it.

I suggest you should consider roll out racks offered by Hercules Hoist Ltd. web:www. indef.com.This product may serve the purpose.

In an ideal world, rotating equipment shafts and or rotors should be stored vertically.

Shafts such as the ones you mention will have either a male or female thread at one or other end, merely suspend them using eye-bolts. Is it worth the effort in your case - only you can answer. Have you had a major problem with run-out of spare shafts in the past?

Actually the shafts mentioned by the OP do not have threads at either end. They are splined at both ends.

This is to allow couplings to engage when connecting either intakes, gas separators or additional pump sections together.

I have worked for many ESP manufacturers over the past 25 plus years and as I said, even if there is a bowing of the shaft it is checked for straightness prior to use and if found to be out of tolerance, it is corrected very easily. storing correctly and the horizontal is the key to this problem and after doing some research, the material they shafts are made of will also play a part!

OK, but if that is the case then storage as per Solar Eagle's post No 19 is ideal. Another advantage of storing vertically is that the tendency towards corrosion under the supports is reduced and inspection easier.

The material the shafts are made of don't (usually) corrode.
Further to that, all the shafts I ever saw stored in the horizontal were resting on wood, so not to damage the shaft surface when placing them metal to metal..

Next time, say everything in the original post. It saves such a lot of time.

Well it took time to find out what sort of shafts you are asking after!

Centrifugal pump shafts, depending on the type, size and material will tell you the sort of storage you should arrange.

BUT having worked for several large ESP manufacturers, they would store the shafts on racks, horizontally with several support cradles so the shaft was support every 0.5 of a meter (±).

That would stop the bowing of the shaft, however each shaft before use was examined to ensure it was straight, if not then it was straighten.

Sir,

I completely got your point and here in our plant also the shafts are stored horizontally with supports but what we are observing is that shaft issued from warehouse are having excessive run outs ( more than 0.1 mm ) , problems is particularly high in long shafts with smaller dia ( long means 1.5 m and dia 25-35 mm ) , this may be because of deflection in shafts due to self weight. So its it advisable to store vertically?

NO!!

You do NOT store these type of shafts in the vertical........

I suggest you look at your racking system, and increase the number of supports along the length of the rack. Having two supports for a long shaft, that is probably hollow is the reason why it's bending.
However you should be checking to ensure it's straight before using. If it has a bend, then it needs to be straighten before use.

If you add more supports in your rack, then you will not have the problems you are describing.

FYI.. the shafts of a submersible centrifugal pump are designed to bend, as the whole of the assembled pump has to bend to be able to go through the deviated well section into the horizontal.

Sure vertical will work, with a plastic bottom to protect the shaft, boxed at the bottom to keep it from sliding out, and a open box at the top secured by a chain to keep it from falling over....or you could just make the supports on the horizontal storage at the balance points of the individual shaft....custom for each length.... which would probably be about 1/4 of the length in from each end....

Are you sure the shafts did not have excessive runout prior to storage?

Everything is coated with oil, covered in plastic and encased in a wood or cardboard container set on wood pallet or shelf....

Bar stock is coded for size, bundled, and stacked on wood supports...

Which one of these shafts do you mean?

Shaft

From Wikipedia, the free encyclopedia

Shaft can refer to

The English Wiktionary has a dictionary definition (meanings of a word) for: shaft

When I was working in Wastewater treatment, we had many vertical turbine pumps with progressive impellers. As an average, these shafts were approx. 20 - 30 feet long and approx 2 - 4 inches in diameter. They were stored horizontally in the wooden crate that the manufacturer shipped it in, inside of a warehouse. We never had an issue with corrosion or run-out unless the forklift driver was careless when transporting the shaft to the rebuild area. it seems that the shafts you are dealing with may be faulty from manufacturing or from improper handling during transport and assembly.
