I would think that there are some variables here that you need to give up to
the group so that an educated guesstimate at the answer can be made. Are
you filling from 0psi to whenever the switch kicks out. What pressure are
you filling to? How about you publish the time that it takes to fill the
tank from kick on pressure to the kick off pressure, and what these
pressures are. If your kicking out at near the max pressure of the pump
then its going to take a lot longer to fill that if you lower max pressure.
Max pressure is about 175psi ( I think) on a two stage and if your running
to this pressure or above its going to take a long time. Also consider that
the pressure switch may be going haywire and not shutting off reliably. If
you google this newsgroup you will find this discussion has taken place in
the last year or so.

I'll let you silly top-posters figure out what order those posts and
replies go in...

Question that come to mind are "Why are you having to start from zero
PSI? What leaks which would cause that? Why don't you fix THAT? And to
what PSI are you pressurizing?"

Mine turns on @ 150 PSI and off @ 175 PSI. It takes 1 minute 20 seconds.
Don't have a clue how long it takes from 0 pressure, I rarely turn mine off.
I have 3 phase delta service and an identical compressor.

I have been tryi ng to figure out why my compressor leaks down and will
eventually empty after about a week. I finally narrowed it down to the
pressure switch. Anyway, it is currently set to turn on at 145lb and off at
175lb. Except for the slow leak, the pressure switck works fine. It is a
square D brand. I am looking for a source to get a replacement.

Thanks afor all the help.

Interesting that it's the pressure switch leaking, although not much of a
leak. Fittings tight? Soap might show where it's leaking. Graybar is a
Square D dealer.

Harold

You might have a very small leak around the edge of the pressure switch
diaphram. See if there are screws in a circle around the section that
sandwiches the diaphram to the bottom of the case.
Just don't try to remove the screws while the tank is pressurized.

If you can snug the screws a bit, it may stop the slow leak. If it leaks
after snugging the screws, you might need a new switch, although a good
Square D product/parts distributor might be able to locate a new diaphram
for your specific switch model.

Ask Quincy. They come that way, likely because higher pressure is used to
provide a larger supply of air (at lower pressure). These are compound
compressors with a cooler between cylinders, and what I consider to be slow
speed machines. They do not resemble the small high speed clatter boxes
that are marketed as compressors. They're serious machines.

Harold

Wild Bill,

Thanks for posting. I did snug up the screws around the edge of the
pressure switch diaphram. They were in fact lose and tightening them
dramatically slowed the leak. Unfortunately, it still leaks. I will
probably have to replace the switch.

Thanks again for the help.

Damned if I know, but I'm pleased it operates at the higher pressure. I
have an air system on my 1 ton Dodge that turns on @135 PSI and off @ 150.
I use a slightly modified auto air suspension compressor to fill the tank,
which is quite large, but I can pre-fill it with the Quincy if I desire.
Couldn't do that with the lower pressure.

Quincy makes more than one model compressor. Could be you have models
different from the ones in question, or yours have been set with different
operating pressures intentionally. Are they dual stage? Do they unload?

I went to the dealership where mine was purchased to buy a seal for the
crank, which had started seeping oil----when the compressor was something
like 20 years old. I inquired at that time what it would cost to replace
the compressor and was shocked to find it was something like $3,000. I had
paid about $1,000 when I purchased it, new. They had introduced a lesser
expensive model that was being sold with similar specs. Can't help but
wonder if maybe that's what you have. I've noticed that single stage
compressors are operated at lower pressure than are the compound models.
At any rate, the turn on and turn off pressures were factory preset and have
never been altered. Did you buy yours new, and are the controls set as
manufactured?

Considering mine is over 34 years old at this point, and is still pumping
dry air (no trace of oil) and has had virtually no trouble (leaking gasket
and leaking seal), I'm not convinced I should be worried about how long it
will last. It has hydraulic unloading, so it starts load free. High
pressure isn't an issue in that regard.

I have set mine up with 70 on, 100 off. Ive a seperate 80 gallon
receiver for additional storage..and have never found a need for any
air pressure over 100lbs. Shrug...YMMV of course.

My Quincy runs at aprox 300 rpm. It was made in 1963. Still runs
fine. Though it has a faint faint clank now..could be a valve hanging
or time before long for new bushings on the crank. Before I got it,
it ran virtually 24/7 for 30 yrs in an oil field shop.

I have two #325 and one #qr-25 I can't tell them apart and the parts all
seem the same. They are all 2-stage and will do higher pressure. We bought
just the pumps over the years and mated them into our existing system so
nothing is factory OEM. Our back-up is a 10 hp "Hydrovane" that we run for
a day every quarter to service the Quincys. They get fresh oil and a valve
cleaning. We try to track-down leaks that will drain the two 80 gallon
tanks in about 5 minutes after shut-down but seem to only find the most
blatant. I'll bet I'm paying twice as much for air as I should.

That's a damned shame. I never turn mine off. I have a couple very old
nozzles I use, one on the mill, one on the lathe. They're the type that
aren't OSHA approved, with no safety vents. I really like them, so I use
them, and I'm the only one that has access to them aside from Susan. OSHA
isn't a factor. As long as they are well lubed, and the insert is
properly tightened, they don't leak. Even with my compressor set @ 175
PSI, it will often not start once a day, so I'm obviously not losing much
air.

I rebuilt all my Milton connectors (something like 20 of them), replacing
the steel valves with stainless ones that I made, and made new gaskets
(which I also made), so they do not leak. I imagine it's nearly
impossible to have an air system totally air tight, but yours sure sounds
like it's pretty porous. Imagine if you ran higher pressure!

I have a manifold system and ball valves on my setup so I can blow down
easily. It discharges outside, so there's no mess. It's one of the best
things I've ever done for my air system because I now blow down daily, and
it takes but a few seconds.

We used to have two taps at every drop, one would be 125 psi and the other
regulated to 30 psi for blow guns. Each tap was a different style of
connector so the people couldn't plug a blow gun into the High pressure. In
those days there weren't safety blow guns. Somehow, we ended up with just
the one style and of course, they are hard to find and expensive and there
are well over 100 of them. Every six months or so, I try to get everybody
to track down all the leaky fittings, We rebuild the fittings and make new
rubber washers for them and it's better for a while. I do believe it would
be cheaper to replace ALL the fittings with cheaper, more popular fittings,
I'd say $600 P+L, than run 15 HP twice as long as I should have to, about 60
to 70% run time. I'll have to do the math and see when the pay-back is.
But, I certainly love my Quincys!!! I wish I had other no-brainers.

Yep! Of all the machinery I've ever owned, I can't think of one other that
has been so reliable and trouble free. They truly are a nice piece of
equipment. Here, in timber country, the skidders are pretty much all
equipped with one of the 10 horse heads. If you've ever seen how such
equipment is used, you'd likely understand that a piece of junk wouldn't
last a day.

Mine has the old type oil pump, which apparently had given some trouble. I
know that's one of the things they changed with later models. I've never
had the slightest problem even with that.

I have a distinct advantage as compared to you. Regardless of the quality
of employees, once you have a herd of people using equipment, things have a
way of degrading. I'm not surprised you have so much leakage, and I'm not
implying that it's intentional. When you're the only person using the
service, it's immediately apparent when there's the slightest problem and
you can deal with it.

I'm not convinced new fittings would solve the problem. Have you given any
thought to changing the nature of the seals? Maybe something softer, so it
takes less effort for them to seat? Also, are your lines iron? Rusty? I
violated all the rules and installed 1/2" PVC pipe after experiencing rusty
iron pipe, but before you jump to conclusions, understand that virtually
100% of them are cast in concrete, where they can't explode violently. The
system has worked beautifully so far, to which I attribute my dry air. Any
oil could change that in a hurry. I realize you can't use PVC, but
getting away from iron is a great idea, assuming you're using it. Had I
not been placing my pipe in concrete, I'd have used copper. I explored the
ABS air lines but realized that I'd have to rob a couple banks to afford it.
Nice stuff, but very pricey.

Mine has the old type oil pump, which apparently had given some trouble.
I
know that's one of the things they changed with later models. I've never
had the slightest problem even with that.

I have a distinct advantage as compared to you. Regardless of the quality
of employees, once you have a herd of people using equipment, things have
a
way of degrading. I'm not surprised you have so much leakage, and I'm
not
implying that it's intentional. When you're the only person using the
service, it's immediately apparent when there's the slightest problem and
you can deal with it.

I'm not convinced new fittings would solve the problem. Have you given
any
thought to changing the nature of the seals? Maybe something softer, so
it
takes less effort for them to seat? Also, are your lines iron? Rusty?
I
violated all the rules and installed 1/2" PVC pipe after experiencing
rusty
iron pipe, but before you jump to conclusions, understand that virtually
100% of them are cast in concrete, where they can't explode violently.
The
system has worked beautifully so far, to which I attribute my dry air.
Any
oil could change that in a hurry. I realize you can't use PVC, but
getting away from iron is a great idea, assuming you're using it. Had I
not been placing my pipe in concrete, I'd have used copper. I explored
the
ABS air lines but realized that I'd have to rob a couple banks to afford
it.
Nice stuff, but very pricey.

I love: "herd" of people, on SO many levels. At least there are drip legs
with valves and filters and oilers EVERYWHERE but the lines are all 3/4"
black pipe. I may tirade about anything other than black pipe but the next
leg we do will be in copper! Quick math: 40 amps, 9600 watts, 9.6kw/hr
$.15/kwh = $1.44/hr
$1.44/hr * 70% duty= $1.008/hr cost for air. Lets say I'm wasting $.40/hr.
$600 = 1500 hours payback. Compressors run 2000 hrs/yr. Leaks cost
$800/yr. Math sound fair if not conservative?

Yeah, I was pretty proud of that one as it came from my fingers, too. Sure
is appropriate for most scenarios.

I've yet to see the joints leak when soldered, and it's faster and easier
than cutting threads. It's really a nice way to go, assuming you can
secure the quick connects such that they don't move about. It requires
very rigid terminations, but that's not difficult to accomplish. I faced
the same thing with my plastic pipe, which transitions to a short steel
nipple in either a tee or ell, also cast in concrete. My connects are
totally supported and rigid.

Gasp! And I whined when they raised our rates from .$0033 to $.0044/ kwh?

Yeah, the math looks fine to me, but then what the hell do I know? g

It would be real good to get the leaks under control. It's more involved
than just the money, too. Think of the extended life of the compressors.
Keep us informed, and good luck!
