Hi All,
I'm designing a compressed air system that gets a connection from a Plant Air compressed system at 7 barG. I want to size the connecting piping in the way that it can provide enough flow and pressure to the all spray nozzles in attached. There are two types of nozzles (S1 and S2) need...
Hi all,
I have a curve from a compressor supplier that provides Allowable nozzle loads based on the attached values (A line between Maximum force and maximum Moment). When I do Caesar II analysis I get Fx, Fy, Fz, Mx, My, Mz values at the nozzle location. How can I relate the F and M values...
Hi All,
We have a 12 m3 above-ground Diesel tank and fuel bowser fabricated and installed in Australia.
For the person who does the inspection and maintenance on this diesel tank, is there any certification or qualification required in Australia that he needs to have? Such as the Type B...
Hi All,
i received a stress analysis done in abaqus and have a question as using Inventor Professional 2022 to do similar analysis. In the received report instead of the stresses it talks about residual plastic strains in the material. If i want to do a linear static analysis in Autodesk...
Hi Mint,
Thanks for your response. Do you know European or US standard that refers to this issue? I cannot find any particular one in this regard.
Thanks,
Hi All,
I am working on a crane that will be used in Australia and I thought that people working in the railway or crane industry may be able to assist me.
According to the Australian standard AS 5228.1-2021 (Table 101) and AS 1418.1-2002 (Table 7.20.3.6), the fillet radius between the tread...
Hi All,
For a similar applications and a different motor fabricator, the bolt torque that the supplier provided us was 50% of the yield stress of the bolt. So, I'm a bit concern about of probability of the casing breakage if I want to torque it up to 70% yield.
thanks,
Thanks guys for replying.
I m looking to find the minimum torque that i can use to avoid breakage of the casing and in a same time can keep the drive in place.
I m thinking of using bolt grade 8.8 for this motor but using the torque specified in the standard bolt table is too high and may break...
Hi all,
We have an unbalenxed vibrating exciter for a vibrating screen and require to know what bolt torque is required to fasten the vibrating motor to the screen frame?
Considering the point that the motor is an old one and the manufacturer is not available is there any way calculate the...
TiCl4,
I checked with the guys and they are saying that Emission requirements forced them to use a dust extraction system (Wet Scrubber). Again no difference in my scope as I need to know the amount of steam and dust coming out of the slaking system. how should I calculate it?
thanks,
Hi Guys,
I'm based in New Zealand now.
It is located outdoors. Almost in all clients' sites, there are some Wet Scrubbers for quicklime slakers that collect the dust and sucks the steam out of the slaker mill.
there are not many articles published in lime subject.
I'll try to contact these guys...
Hi All,
I need to design a dust collecting/extraction system (Including ducting and fan selection) for a slaking ball mill that slakes Quicklime material and want to know how much dust and steam comes out of the slaking ball mill that I can design correct ducting and select a proper fan. The...
Hi All,
I need to calculate the water film thickness at a bottom of a conical hopper with two inlet nozzles on top side (as attached). Have you seeing any calculation /article that can be used for defining water film thickness and water velocity at the bottom of the conical hoper attached...
Hi all,
For preparing hydrated lime from quicklime, after screw feeder there is one vortex mixer which adds water to quicklime powder before going into slaking tank. How can i find some information about designing a vortex mixer and what the requirements of correct design are.
Thanks in advance
Hi All,
Our pump supplier has mentioned that water entering the mechanical seal needs to be quench water. On our site we do have a RO system and want to make sure that Quench water is the same as RO water. Are they same or different?
thanks in advance,
best regards,
Thank you very much Itsmoked. Apart from pump performance, what is generally minimum speed can be achieved by AC motors? Are you saying that an Electric motor speed can be decreased to 60%?
Hi Guys,
I’m a mechanical engineer new to electric motors. Could you please reply to following question.
1. We have a centrifugal pump that required AC motor size was 2 KW but 7.5 KW selected to account for future pressure drops due to changing the line. Is it a problem to use that big motor...
