Re: oil compressor problem
Do a pump down test to check if your discharge valves are OK
Re: oil compressor problem
Mr. Frank I make pump down it's ok
I have one eqution it's normaly go with ***** small quntity of oil , is that right
Re: oil compressor problem
On a small system you should not need to add additional oil to the amount recommended by the compressor manufacturer.
On larger systems it is normal to add additional oil to compensate for the oil that moves around the system.
Re: oil compressor problem
Ok, I have to tell you more information in this circuit there is no oil sapreater. Is it necessary to install oil sapreter
Re: oil compressor problem
It depends on the size of the system
Re: oil compressor problem
Hi Alamda.
I would suggest that the abnormal (I assume the amount of oil being dumped system side is abnormal?) oil carry over is very likely to be the result of wear internally within the compressor.
The Rings, Valves and Springs are a good place to start.
These comps are usually highly reliable, so ever mechanical wear or failure would be a good assumption.
When a recip has worn piston rings and liners (or even broken rings) they become a very efficient oil pump!
When you had the heads off did you check the sump for debris or metallic particles within the oil.
An oil sample analysis may prove useful.
Some recips have bypass valves within the head / liners, if relevant this could have an issue?
Good luck Grizzly

Does your system short cycle? If so, check out this link.

I think Franks comment is all the more relevant having read it!
Plus add a working crankcase heater and Oil Foaming is minimised.

can you tell me what is the size of the system needs to add oil seprator?
Re: oil compressor problem
lose of oil have a lots reason.
rings
valve plates
high temp. of oil
oil type
foaming of oil in starting time.
wrong piping slop in suction line also u trap
blocking oil return from oil separator

please can u help me what is the resons of foaming of oil in starting time & How to solve this problem ? And the normal temperature of oil ?
