Oil separator
Hi
How and when the compressor sucks the oil back from oil separator ?

Re: Oil separator
There is a float inside the seperator, it opens when enough oil is available to return to compressor.

Re: Oil separator
Thanks Emmett
So you mean the compressor is always make sucction action and the separator's float releases the oil ?
Is the separator return line linked to the same chamber of compressor sucction line ?

Re: Oil separator
Acrisoft.
I am confused because the oil separator is normally on the discharge side of the system.
And therefore the oil is being pushed to-wards the compressor via the oil return line under discharge gas pressure.
Yes you can get some oil return via the suction which is carried over provided the refrigerant gas swept volume is sufficient.
But the amount is minimized due to the oil recovery via the oil separator on the discharge side of the system.
Just what size of system are you referring to?
Are you looking at a slop pot? Which is something entirely different.

Re: Oil separator
There is some useful information on the Sporlan Literature website which might be worth reading through, maybe it will answer some of your questions.

Re: Oil separator
in inside of some oil separator is float vales , so when oil reach to that level it open and let oil goes back to crankcase of compressor ,
also in some of oil separator if we do not have that system we use this system we have solenoid valve with orifice on it ( solenoid valve energized when compressor running) in the returning oil pipe from oil separator to compressor.

Re: Oil separator
discharge from comp through the oil sep, the sep picks up oil from the discharge from comp
depending on the oil set up, dont confuse the oil sep for the oil rez.
you can also have a suction accumalator ie slop pot.
you can have a set up where you have an oil sep and oil will be fed from the bottom of sep to comps this is usally on smaller set ups. on larger from sep to oil rez.
or you could have suction accumalator ie slop pot and fed from the bottom of the slop pot to comps.
these little holes in the bottom of the slop pot or oil sep can be prone to blocking.your only as good as your last job
