Generators / Re: Battery bank
« on: April 11, 2012, 09:36:20 PM »
Are these batteries good for what I want to do with them?
They all hold a charge of 6.5volts+.They cost me very little not even scrap value do you think it’s best to invest the money to buy the proper charger for these or try and get my hands on the other type of battery.
These batteries came from the back up communications system of a very large pharmaceutical company when they moved and building was demolished. They hadn’t reached their service life.

Casey, I found a fork lift charger... the supply it requires is 240volt 51amp? In the UK?


I would agree with a 48 volt inverter, but pure sine wave is going to cost.

As regards the batteries, a slow charge won't hurt them right until you overcharge.  Also AGM are sensitive to high temps.
I really like the Outback inverter/charger, but it runs around 1900 USD for the 48v 3600 watt unit.

If you wanted, you could link all 12 in series/ parallel (2 parallel strings of 6 batteries in series) which would give your 36 volts 200 AH or 7200 wh storage.  If you only drew that down 50 % that would give you 3600 wh; you could run a refrigerator for about 12 to 18 hours with that.  3600 wh requires ten amps at 240 volts for two hours, allowing for losses.

Things I want to Buy / injector pop tester
« on: May 01, 2010, 03:35:27 PM »
Have been looking for some time for a pop tester.

Recent problems with my Case 580 diesel have made this quest more urgent.

Ideally, I would find a unit with adaptors for:
- Case g188D injectors (first priority)
- Injectors for a Cummins 5.9L TD
- Bosch injectors for Volvo/VW diesels
- Listeroid injectors

If you have something you'd like to offer, post here or PM me.

THanks!

Other Slow Speed Diesels / Yanmar 3tn 23 hp diesel
« on: December 11, 2007, 03:24:18 AM »
Just scored a Yanmar 3tn 23 hp diesel. 
It needs some micellaneous parts like exhaust studs, exhaust gasket set, and an air cleaner.

I was thinking that this might be an opportunity to simplify my existence;  since I am looking for
a better solution for an air and fuel filter for my 'roid, and since they use about the same amount of air, I
thought I might standardize on fuel and air filtration.  I did think about using the same filters I have for my Dodge
5.9 liter Cummins Turbodiesel....... but that's PROBABLY too much overkill even for me.

I am probably going to get an 87 Jetta fuel filter or three just to have a simple easy OTS filtration solution;  I'm told
that they just slip onto the fuel lines.  Done.

But I still need air filtration.  Suggestions?

Everything else / Re: So what does everybody use for inverters?

LMWatBullRun,

I know what a TV is, and SS is why we still have tube amplifiers for our best stereo systems, but what is a TVSS?

Sorry, I use far too many acronyms!

T ransient
V oltage
S urge
S uppression

Cleans up any big spikes that ride the AC waveform into the panel.  They are basically a bunch of MOVs
(Metal Oxide Varistor) bundled up and put into a box.  The nice thing about the Square D setup is that it fits right into two breaker slots, very easy install.  They run about $80.  They also sell one for about $40 that can be wired into anything with 2 hots and a neutral/gound.

The power company wanted to rent me a surge suppressor but when I looked at the fine print, they didn't guarantee a damn thing for my $3 a month, so I thought I'd be better off buying my own and saving the rent.

Listeroid Engines / Re: Lubricatig Listeroids
« on: December 04, 2007, 03:03:13 PM »
I confess that I keep hoping that when I check this thread I will find more advice on the stated topic, as it currently is a keen interest of mine.  I suppose that those who have their engines running and producing heat and power are above such mundane concerns and can talk about how to USE that electrical energy..... ;D

We looked at Trace/Xantrex and the Outback, and settled on Outback for the sine wave system;  we have several AIMS inverters for less critical loads that can tolerate square waves.  I liked the reputed ruggedness of the Outback; I had heard enough bad things about Trace reliability to want the most rugged system I could get.  I also installed a TVSS to protect the distribution panel;  we got a Square D QO panel and they make plug-in TVSS systems that take 2 breaker slots.  Seemed a good idea.

Outback can be set up to start a generator, but it isn't as easy as the Trace.  Given that primary generator will be the handcrank Listeroid, and given the size of the battery bank I was not so concerned about having an autostart controlled by the inverter.

Everything else / Re: Batteries, what type are we using out there?
« on: December 02, 2007, 04:18:18 AM »
I've got 2 strings of 8 L-16 HCs.  840 AH at 48 volts  or around 20KWh of capacity at 50% DOD.

I like 'em- can run essential loads plus misc tools for 4 days without going below 48.8 volts.

Does take a while to charge them, though.  They seem to have a low self-discharge rate,
and hold charge well.

That`s a lot of capacity!  Get solar panels, a wind turbine and with your diesel generator you are all set.  What do you use as a charge controller for the 48 volt plant?  Do you start with 120 volt AC from the genset?
Can charge with the Outback inverter and AC, or with the solar panels and the MPPT outback charger.  Still have some trees in the way so don't have final location for the panels, but when I get a couple of days soon my Stihl and I will take care of the trees.  I am keeping an eye out for a windcharger, too, but don't have that yet.

Engines / oil filtration
« on: November 29, 2007, 12:14:14 AM »
Having finally gotten time to unpack and admire my year-old listeroid, I am considering a variety of DIY mods.

One leading concern is oil filtration.

I have seen several different approaches to this.

One is a bypass filter, and there are a number of firms that make TP bypass filters.

Another is to fit an automotive style filter housing using spin-on filters (Baldwin, etc.)
I have followed the discussions on filtration here and elsewhere and went out and bought
a number of 2 micron Baldwins for my fleet, so I the logistics to support that approach are
acceptable.

Still another is not to worry about it and change the oil regularly.

I intend to run this engine at least 6 hours a day every day for the next 50 years.
For maximum longevity, what would the consensus opinion be for the best filtration
method?  I am also intending to provide an oil sump heater by recirculatiing hot coolant
to keep the oil sump hot.

thoughts/added options solicited....

Lister Based Generators / Fidelity generator?
« on: November 08, 2007, 01:45:31 PM »
Picked up what is supposed to be a "fidelity" generator head, 10 KW. 

Doesn't look at all like my ST head.

ANyone heard of these and have any idea where I can learn more?  (Circuit diagrams, etc.?)

Grout-

Now we get to something I know about.

Typical type 1 portland (or 1/3) shrinks slightly when it cures.  Not much, but a little.

This is why what the pros use for grouting bases is non-shrink grout, which uses a blend of expansive and portland hydraulic cements so that the grout just slightly EXPANDS when it's cured.  This locks everything in tightly.  In the case of bolts in concrete, you will rupture either the bolt or the concrete before you get the thing to pull out, as long as the bolt's not greased.

Demo grout is ALL expansive cements, and will actually crack the concrete it expands so much.  Neat stuff- drill the concrete, mix the grout, pour it in at the end of the day and come back in the morning.  Voila! Broken concrete!  But I digress.

ANother option is to use epoxy grouts.  The trick here is to pick a grout acceptable for a high-vibration application, AND to keep the hole as small as you can and still get the bolt in.  THis minimizes the tendency of the epoxy to creep under vibration  and loosen up over time.  The problem here is that you have to drill the hole in EXACTLY the right spot.  This can be done with jigs and clamps and such, but its a PITA and takes time.  Typically this is used for structural attachments in high strength concrete, where 4000 psi NS grout won't do the job, and epoxy grouts are expensive.  Hilti makes a nice system with drop-in capsules that works very well, but like everything Hilti makes it ain't cheap.

I'd suggest using Non-shrink grout, it's a lot cheaper and entirely acceptable in my experience, plus oversized holes and exact hole placement are not an issue.  You can get it at commercial building supply houses.
As far as bolt size is concerned, I have a supplu of surplus 3/4" bolts and thats what I'll use on my attachments;  I'll place them ahead of time in the concrete, so I don't have to mess around with grouting.

Waste Motor Oil / Re: Waste Oil Purifier
« on: July 30, 2007, 04:02:41 PM »
if the flow is higher than expected and the filtration is lower than expected, I would diagnose as either-
Missing filter(s)

Ruptured filter medium, possibly due to higher than expected pressure, high viscosity (cold oil) or shipping vibration or shock.

HAve a PM 28V motor generator that I think I will use both as a DC genset and as a starter.

Sure Gary, I need all the filters and if you have a replacement fuel tank thats an original replacement that'd be great, thanks!
