O.K. I thought that link was due to my computer, because it didn't work for me at first either. It is a very informative link though. I guess that does show that it would be quite hard to determine the phases with an ohmmeter. I didn't realize there was that much going on within a wound motor...
This may sound a little off the wall but, isn't there a way to determine the coils within a rewound motor by using an ohmmeter? It seemed to me we went over this in one of our classes I took some years back. In other words, you could measure the ohm readings between the motor leads and tell...
Most of these fans are old enough so that the labeling is missing, which makes it difficult to find a reference for them. I contacted OSHA by email and they weren't too specific on this either. Most of the wording that I got was too confusing. I wish they put it down in laymen's terms.They said...
Our safety team here at our facility is hell bent on removing all of our desk type fans because the plugs aren't grounded. Where they are made of plastic, most of our department feel this is over the top as far as safety goes.Most of them are probably double insulated anyway. Is there any...
Thanks JJ for your interest in my post. You seem to be knowledgeable in this area based on what you have replied with in your posts. One thing that I did want to add that I neglected to tell you in my last reply was the condition of the rotator. In the two times I've pulled the pump out for...
Well JJ. I am certain that there is no seal flush, unless it is internal to the pump by design, which again as far as I can see does not exist. I really don't feel that there is any liquor between the seal faces at startup as long as the faces are running together. As far as the elastomer, the...
Hello all. Where I work, we have a small single package yarn dyeing machine that has a 25mm Burgmann mechanical seal that is mounted directly on the motor shaft. I'm pretty sure it is a standard carbon stationary/carbide rotator setup. The elastomer appears to be viton. The problem is that after...
I didn't realize that you had a non-condensing type of steam turbine available. That looks like a viable option. Maybe thats what our engineering dept. is looking at right now? Based on what my boss is saying, he evidently isn't aware of them either.... There is a river nearby but, this company...
Probably whatever an electric water heater would put out. Again it would only be needed for hand washing mainly so, it wouldn't require too much. Our boilers generally run at 125 p.s.i.
The way I see it, the cost to actually set one up would not be cost effective. By the time you get one...
Thats some good advise given there, particularly waross. As stated my super has said right along that with all of these electrical reductions your only looking at "pennies" and I think after what I've seen for numbers he's probably right.
Yes, there is talk of doing a cogenereration in...
O.K., this sounds very doable. But, it will be on a smaller scale than the one linked up. Its more like replacing an electric hot water heater with a steam heated one. My thinking is buying a 50 gallon tank and hook it up with a small steam regulator and a single pass line through the tank and...
Wow, I didn't expect so much input. I guess our facility's water heaters would be considered to be occasional usage only. Practically all the heaters are for hand washing only. So lower wattage elements may make sense and as it turns out they're not all that expensive. I agree that we should...
Hello all. This may sound a little off the wall but, would it be practical to use existing steam from a production boiler to heat a small tank of hot water. In other words replace an electric one with a steam heated one? What it is, our plant is doing an electricity reduction project and this...
Hello all. I am hoping someone here can answer a question that would seem a no-brainer to me but, not being an electrical expert, I thought I'd pose it here. What it is, the facility where I work is on a electricity usage reduction program and are looking for anyway to cut back. One thing that...
O.k. I'm back with some more info. on the motor problem. Sorry I haven't been here sooner but, things have been hectic. The exact nameplate info. is: LANDERT MOTOREN AG
No.82821/073 Typ.160W- 4/2F.6.2-03
3 phase S1 6.2/ 2.5 Kw
480 YY/? Volts 9.8/ 4.85 Amps
1770/ 3550/ min...
I'll post back soon with what they ended up with but I guess it was wound right, it was just a matter of the connection. I think it was the 4-5-6 hooked together and the phase leads being 1-2-3. I also want to post what the exact nameplate lettering was as well. As far as starting at the high...
Well Lionel when the electrician tried to hook it up and run on the higher speed, it would only hum. So I again assume that it may be required to be rotating..... One thing I did notice today looking at the nameplate was that it said wye wye / delta. Which I guess must be an indication of the...
Hey thanks Pete for the help on the website. I printed it off and took it to work with me today.This should at least get them going in the right direction. And to you aolalde, for writing up all of those configurations. As stated they could get it to go in the slow speed but, not the high...
Hello all. This is my first post so bear with me. Recently I have been promoted to a lead person job and fill in when my Supervisor is out. This past week one of the shop personnel went out to install a newly rewound motor and could not get it to work right. He said it sounded like it was...
