Kellogg Americpatagonia womens sale1an 2 stage compressor
Last year, a buddy anpatagonia womens saled I picked up an American Kellog 2 stage air compressor. Just got it back together and up and running but it is leaking down.
I have two hypotheses.
The valves are failing and it is allowing pressure from the tank back into the cylinders. If this is the case, then it is just a matter of replacing the valves in the head. My problem with this hypothesis is that the air would have to be leaking down from the tank through two sets of valves (secondary and primary cylenders). Also, the crankcase is being pressurized.
Something isn t connected properly. See the attached photo.
The line with the yellow circle is to equalize the pressure from the crankcase. I am 100% certain it is connected properly.
The second line (two red circles) I am not so sure of. It goes from the back patagonia men's better sweater pale khakiside of the head to a junction block anpatagonia better sweater oranged from that junction block to the main block where I would expect the pressure rpatagonia womens sale0elief valvepatagonia better sweater womens xs to be.
I think that tank pressure is being fed into the head from that line and then into the crankcase (via the breather tube). I cannot, for the life of me, see a good reason to have that line there.
I am hoping someone who is more familiar with these compressors would be able to help me figure this out.
Here is the breakdown (parts list) of the pump unit. There is no mention of the unloader valve or solenoid valve.
There are three ports on the head. One on the top, above the outlet valve and one on the side just to the left of the outlet valve. The port on the top is capped and the one nearest the outlet port is connected to the pressurized linpatagonia guide pants salee (from the main junction block into another block welded to the front of the tank then to the port next to the outlet).
The main junction block contains the outlet, pressure gauge, switch and the port I spoke of. In my experience and logic, that port should be used for a pressure relief valve.
Yes. The line removed releases pressure from the tank and when running releases pressure from the head.
Apparently the unloader is not part of the head assembly (like most newer compressors). I am unsure as to which head port would be the proper one to install it on.
Unfortunately I cannot find a description of each port, only the equalization port on the block and patagonia womens sale2front of the head.
Part of the problem is that the compressor was aquired in pieces, without all the pieces there, so we were going by previous knowledge and our combined mechanical gut and instinct.
We did a lot of research and have not been able to find any conclusive documenmens patagonia better sweater hoody tiba stripetation on this pump and that is why I posted here!
I have included a ms paint diagram of how it was (is) set up. I have Keith removing the Unknown line and capping both ports. This way he can test whether or not the valves are leaking down or if it was tank pressure feeding back through the system.
Apparently, on most models similar to this the pressure swpatagonia outlet store 13itch (to shut the motor off and turn it on) was mounted in the top of the junction block located in front of the motor/pump. The new (NOS) switch is relocated to the top of the main junction box due to the size of the inlet (1/4 PIPE).
Also, where the switch is currently located is (apparently) wpatagonia chile luxury hotelhere the emergency pressure release valve was originally located.
Also, looking into the centrifugal unloader. There is none on this pump. The capped end of the housing contains only the bearing housing.
I am almost positive that this compressor uses/used a pressure switch unloader.

Possibly the 332 (replaced the 331) incorporated the centrifugal unloader, but it is definitely not present on this pump assembly. Anyway, I wanted to ask if that head has a hole on the top just above outgoing line or maybe opposite side thats plugged. I really need a bunch of pics to figure this out. I consider myself pretty good with this old iron but I am missing something. try to take them at 1600x1200 or so, pictures of the hole machine from all sides, the top of the head, that junction box etc. The compressor runs as it should and fills the tank faily quickly, shifts cylinders as it should (can you tell at what pressure it shifpatagonia everlong review zarkanats over?) it starts and stops at 145/175. when the pump reaches high pressure and shuts down, air feeds back through that white plastic line, into the head and therefore the crank case and it then leaks out of the block somewhere and the unit loses pressure. is this correct? How fast does it leak down, can you determpatagonia guide jacket for saleine where it is escaping the block, and how big is the tank? Take note of the the lines on the head in this pic
Nah, the inter cooler lines are on the other side of the pump (behind the drive wheel). They are all there and accounted for.
I have already figured out that the original unloader valve was a pressure type and was integrated in the AC switch (which originally was mounted on the front block where the two grey lines meet). I can only assume, for now, that the port utilized on the side of the head (nearest the output) is the line that ran to the unloader.
I have Keith disconnecting the line for the time being and plugging the line that goes to the tank and putting a manual relief valve in the port. He hasn t gotten back to me on if the compressor was still leaking down.
From what I have gleaned from my research (aided by your insights) is that the original configuration is like the attached ms paint diagram.
