Filling time? IR T30 242, 80 gallons tank

by Lahouache
(France)


Hi!

I bought 1 month ago an IR compressor 2 stages from 1979, Type 30 model 242, tank capacity is 80 gallons (300 liters here ine France ;-) ).

It needs 10 minutes to fill from 0 to 8 bars.

I saw a video on youtube about an old IR from 1968,
" Ingersoll Rand Type 30 7.5hp Model 57T "
and it was faster (4 minutes) to fill from 0 to 9 bars, but the capacity is not mentioned...

Mine was in a farm. May be need to rebuilt rods and valves...

What you think about that?

Hopefully, we can easily find spare parts for those nice compressor... Compare to an old french Creyssensac single stage V cylinders 1970 500 liters of my dad, mine is very quiet.

Guillaume.

Bonjour, Guillaume.

Without seeing the compressor and trying to figure out why, I suspect you have valve wear or gasket failure... but it is impossible to be sure.

The Troubleshooting section has page links about reasons why air compressors will not build pressure, or build pressure fast enough.

Have a look, and if you can pinpoint specifics, I or other visitors may be able to suggest specific solutions.

And, of course, you can always contact IR directly.

Cheers,

Bill

Problem found!
by: Lahouache

Hello Bill!

I opened the top head cylinder of 1st stage, the bigger one, and the gasket lost a part of itself between the entering (low pressure, from outside) & the exit (goind to the 2nd stage, smaller cylinder).

It is an armed (right word?) gasket with metal fiber metal inside.

I'll look for a sheet of the same type to cut a new gasket inside. It will be cheaper than buying ont Ecompressed-R, because of fee to ship it to France.


I have a photo to illustrate, but now I can't post it.

Thanks for your job on this site,

Guillaume ;-)

No. Thank you for visiting and posting. Why not start a new thread with photos. I expect a lot of people would like to see them. And, I think you may find that the "armed" sheet is actually the valve plate.

Ingersoll rand T30 Air compressor three phase air compressor will not start?

by stan hirniak
(Kilmore ,victoria ,australia.)

Ingersoll rand T30 Air compressor will not start with a diesel generator. It has been wired up correctly to a 20 amp rated three phase male socket.
The air compressor was dormant for many years and was recently acquired after a disposal/ auction sale.
Both the V twin motor and Toshiba electrtic motors are not seized as they can be turned by hand
The compressor has a auxiliary power board where it can be started and turned off.
I wired the four wires correctly as what was previously utilised in the auxiliary switch box.
The fifth wire was black and was not used.
The wires used are red,white,blue and the green/yellow.

Stan, this is well beyond my capabilities. I am happy to post your question in the expectation that those more learned than I may respond.

Of course, you could always liaise with IR directly? company.ingersollrand.com

The Chinese generator specifications are as follows-
Rated Output 5.75 kva @cos 1.0 or 7.2kva @cos 0.8
Max Outpur 6.6 kva @cos 1.0 or 8.2 kva @ cos 0.8
Dual function 415v 50hz/250v.
Toshiba electric motor is 415 volt ,21 amp and 11kw.

buster . He is a Update.
The ingersoll rand T30 compressor is a V Twin (from memory it is 5.5inx3.5 inch bore) and the electrical motor is a Toshiba 11kw,415 volt rated at 21 amps.
The wire coming out ot the electridal wires are light guage (four wire) and feed into the master control panel.
The wire coming out of the master panel were of the higher guage-9.00mm and of the five wire variety.
Black wire is not used but the other four wires are used.
The four wires coming out of the motor were of the light guage and I assumed it would be safe to use the same supplying power via a extension lead of the same construstion to the master switch/box
Yesterday I got two inches of movement from the electrical motor using the above extension lead.
Should I buzz in the thicker guage wire-(9.00mm)?
Is there voltage drop?
How do I get photos uploaded of the both the compressor and the components in question for you to make a evaluation?
Perhaps I will have to clean connections at the electrical motor end as it has not been running for many years?

Need more information
by: Buster

Hey Stan, sounds like you have checked all the electrical connections to be correct, just need to make sure the genertor has the correct voltage output and current capacity for the motor, and that the genertor is functioning properly. T30 compressors can have anywhere from a 1 HP motor on up to 30HP or more. You did not say what size your generator is or what size the motor is or if it tries to start or makes any effort to start. There could be several things that will not allow it to start, oil switch, control fuse, breaker, overload tripped, pressure switch, etc. I am not sure what the control panel you refer to does, pictures would be great asset to troubleshooting.
Hope you have a great day.
Buster

ingersoll rand type 30 ~ motor cuts back in motor(sometimes) fails to accelerate to full speed.

by Phil
(Yorkshire UK)

Machine is an IR type 30 4" and 2 1/2" x 2 1/4" model 242 ser No TP 95442 L15.

Motor is a Brook-Crompton 3 phase 415V 4kw (5.3hp) 1420 rpm with a 9" twin vee pulley.

compressor starts fine, accelerates (maybe a little slowly) and quickly fills tank to 100psi and cuts out.

When air is used and motor cuts back in motor(sometimes) fails to accelerate to full speed.

rpm rises enough to shut the PRV then falls again and PRV opens again.

Motor is not drawing excessive current, it seems that it does not have the power to start the compressor when there is air in the tank.

I have checked and serviced the non return valve, checked the PRV which is working fine, and dumps the pressure from the high pressure side every time the tank is full and the compressor cuts out.

have removed both cylinder heads and checked bores and valves all seems to be ok.

I have checked the supply phases, current consuption per phase and all seems normal, motor does get hot after a few cycles..

I have come to the conclusion that either the motor should be bigger (7.5Hp) or the pulley smaller. Can anyone help?

Phil

Phil, I am happy to post your request.

The interaction between the pressure switch and the throttle is where I would be looking.

My sense is that your issue is a mechanical one, and you might consider getting a mechanic to sort it out for you.

Cheers,

Bill
