    Problem opening large Solid Edge files

    File sizes vary, anywhere between 96MB to 575 MB. They are all engines so I imagine there are a lot of parts. I am not sure about the layers or sub assemblies. I will look up the 3GB switch, have not heard of that. I did find out from Solid Edge support that parasolid is the best option...

    Problem opening large Solid Edge files

    I am having trouble opening large solid models of engines sent to us by our vendors. Generally, the vendors work in Solid Works and have to convert to one of the following formats that Solid Edge recognizes: *.x_t (Parasolid) *.stp (step file) *.igs or *.iges (IGES file) I get a message...

    Bolt holding strength?

    I have since talked to the machine shop lead and now I have a little more info. The flanges are for a cast volute for a pump to which a hydraulic motor is connected. The original drawing calls for 12 bolts to attach the motor flange to the volute flange. We have a few of the volute castings...

    Bolt holding strength?

    Not sure about the load or margin, as this is an old design done by someone else and I have no information in that regard. I apologize for the lack of information and wish I had more info to work with. The flanges are fine. It might be possible to increase the preload, I will have to find out...

    Bolt holding strength?

    I have two flanges bolted together and their is a problem with the way the holes have been drilled. Normally, the assembly is held together by 10 bolts. Because of the error in drilling, if we were to try bolting then together only 6 of the holes could be used, but I believe they are equally...

    Changing industries?

    Yea, I'm not planning on jumping ship right now. We're not doing great (money wise) but I like the people I work with and don't dislike the job that much. I am friends with our CFO and he tells me we are at least ok financially for another 2 years. More or less looking for ideas at this point.

    Changing industries?

    How do you go about getting into a new area of engineering once you've been working in one for a while? I graduated with a BSME in 2003 and have been working in manufacturing environments (3 ½ years (1st job) in designing shipboard components, currently about 1 year (2nd job) designing pumps...

    Need material recommendations

    I have an application where I need to provide a pump that pumps a 25% concentrate magnesium chloride from a pond. My main concern (or question) is about the volute and impeller material. From what I've read, magnesium chloride is fairly corrosive. Has anyone worked with pumping a solution such...

    Sound attenuating enclosure?

    I am working on a design for a portable sound enclosure to cover a diesel engine. I don't know much about sound attenuation, but initially am thinking about a sheet metal type enclosure with sound attenuating material or baffling on the inside. The requirements I have is that the enclosure be...

    Audible warning system?

    macgyvers2000, I don't disagree. The reason I'm looking into a voice system is because it is a request of my boss. We do have safeties in place. He just wants to add an audible voice, mainly for the novelty factor. I don't necessarily agree that it will be a good idea, but I am looking into it...

    Audible warning system?

    GonzaloEE, I like that idea. I checked on MP3 player boards online and the price varies wildly (from $25 to over $200). Any you could recommend in particular? And what do you think would be the total cost of making something like what you suggested?

    Audible warning system?

    macgyvers2000, I agree, but I'm still leaning towards a voice system simply for the novelty factor. It would be cool to have a talking pump. How much more complicated would the circuitry have to be?

    Audible warning system?

    geekEE, Would prefer something off the shelf. And it would be a high volume application, I would like to implement it assuming it works well.

    Audible warning system?

    Actually, I was thinking the voice would only activate to warn of problems. A few voice commands to warn of a few specific problems. This would likely occur when the pump is not running, so noise would not be an issue.

    Hydraulic vs. electrically driven pumps?

    Thanks for all the info guys. We are going back to the customer and telling him electric is probably not the way to go in this situation.

    Audible warning system?

    mcgyvr, I don't know. I'll have to research and get back to you on that. macgyvers2000, Most of the pumps are pretty loud. What I was thinking was more along the lines of some pre-recorded voice prompts that we could use. Would that be more difficult?

    Audible warning system?

    I work for a company that rents and sells pumps and we've been discussing trying to incorporate some sort of audible warning system for when something goes wrong with one of the pumps. We actually have a system in place that alerts us when something goes wrong, but no audible alert. I know...

    Hydraulic vs. electrically driven pumps?

    It's actually customer request, a particular customer likes the pump itself but would prefer it to be electrically driven.

    Hydraulic vs. electrically driven pumps?

    I have some more info. I am relative newbie at design, and I am looking into designing a submersible pump that is electrically driven (an electric motor directly coupled to the submersible pump). I actually have a hydraulically driven model to go by, so I would probably just need to figure out...

    Hydraulic vs. electrically driven pumps?

    How about with respect to: 1) Weight 2) Starting Time 3) Noise 4) Maintenance
