I did a search ten pages deep, but did not find a question/answer to what I'm looking for.
My company has been awarded an order for our industrial equipment where the customer wants all 2D drawings with their title block and border.
This has caused some consternation in our Engineering...
I'm looking for pros or cons to arrangement of thrust and radial bearings for pump use. I do have the "Bearings in Centrifugal Pumps" by SKF (1995) which shows the various arrangements, but doesn't go into enough detail IMHO. The classic arrangement I'm used to is having a thrust bearing...
I'm working on developing a new (and significantly improved, hopefully) drawing number system. Many of the systems I've seen in the past included a character within the drawing number that indicated the drawing size (either small, medium or large or A, B, E, etc). Is there any reason to do...
I've got Inventor 6 and SolidWorks 2005. Neither program handles true 3D very well.
So if I want to loft between two 3D sketches (i.e. NON-PLANAR), what program will do it?
I am looking for individuals or companies that have used plastics in applications where internal passages are required and not produceable with standard injection molding tooling. Say, for instance, plastic casting and sand cores or similar.
Anybody?
OK, I've had outside help with mold flow analysis before and have tried the new MoldFlowXpress in SW2005, which just like the COSMOSXpress is neat but I need more. I've placed a call to my VAR, only to find out they sold out and I've got a new VAR in my area, which doesn't sell MF, but can...
Anybody know where to find viscosities of injection molded plastics, such as polypropylene, pvc, etc? Or how the ASTM D1238 melt flow rate standard is related to stnadard viscosity units (SSU, cP, etc).
OK. We just downloaded the SW2005 Pre-Release 2 version to try something on the new MoldFlowXpress feature. Well, I am glad it is inthere, but it is as watered down as COSMOSXpress.
My beef is with the new trim feature. It seems they felt the need to use a CADKEY style selection instead of...
I did a quick search, but nothing came up. How can I link a non-driven dimension to a driven dimension? Picture an o-ring groove (gland) and I want the landing on either side of the groove to be the same width, with the inner diameter landing having a driven dimension (to the cavity I'm...
I have to produce multiple parts that don't lend themselves very well to multiple configurations and I'd like to copy the steps I did previously, w/o having to review the existing file. Can I print the Feature Manager hierarchy or export it to Excel or something? I guess I could doa print...
Can anyone tell me the spec. (IEC or ISO) that provides the dimensions for IEC motors for close-coupled pumps. I think it is B5 or B14 face- can anyoen confirm? Thanks.
I've designed a plastic pump in SolidWorks, but was wondering if there are any add-on packages that deal with material shrinkages? I'm aware of MoldFlow from a fluid dynamic standpoint of the fluid (resin) inside the mold, but I don't think it would deform your model according to sprinkages...
I've had a little bit of experience with VFDs - enough to know about the characteristic leakage current to the ground circuit. If fed a single phase input, is there anyway to get a GFI style protection?
To further state the issue: using VFDs in residential applications with either 115 or 230...
I've had trouble with eDrawings where either the section of an assembly shows up slightly off center. This has happened twice, once with a assembly that I used the section tool within eDrawings, and the other time when I made a cut on the assembly, created a drawing and then published an...
I've done a search on this forum and on Google. It seems everyone has an opinion on air versus oil motors. What is the straight scoop? I can only imagine oil being good to moderate temps better than air, but other than that air seems better. Any thoughts?
I'm looking for a VFD (pump application, so variable torque) that is NEMA 4 (Washdown or similar), 208V 1 Phase input driving 3 HP load max. The trick is to have a drive that'll restart automatically w/o manual input and at the LAST KNOWN FREQ w/o having to resort to a separate POT or...
Is it possible to create a 1/4 section within SW2004? With the Section command, it is quite easy to create a 1/2 section (choose a single plane) or 3/4 section (two planes). As I see it, the first section plane makes a full cut and therefore does not permit what I call a 1/4 section.
Also...
When you get right down to it, just how important is UL/CSA or similar certification? Does it reduce the amount a jury awards a user in the event of failure? Does it protect you from lawsuits to begin with? Is it required by law in certain areas? Do insurance companies withold payouts if a...
