Hey Trevor, ever since I’ve been studying about these semi hermetic Compressors, I’ve saved a few customers time and money just by taking a few extra minutes of taking apart the compressor. I really love and enjoy these videos. Please keep them coming.

hello Mr Trevor thank you very much for this video too! I have advanced more in my skills about These semi-hermatic and scroll compressors I have been able to prevent liquid flood back avoid flood starts and avoid overheating many of my customer equipments had a lot of errors in their installations and because of you I am so happy of what am i becoming. thank you! Then could you have covered screw compressors too! could you be having the same video covering screw compressors the same way like in this video! screw compressors for chillers!

For sure too much oil or liquid refrigerant will damage the compressor. More great content at www.refrigerationmentor.com

You could have damaged cylinders and piston rings from overheat which is causing blow by. But it could be other things as well. Great question.

Can the oil pick up tube be accessed with out taking off the bottom plate on a 4D compressor? I just liked/subscribed
@RefrigerationMentor Жыл бұрын
Great question. There is not an oil pickup tube in the 4D compressors it has ports drilled out in the casting to the oil pump. K body compressors have pickup tube and you can sometime get them out without taking the bottom plate off but you have to be careful not to break it.

Do you have to drain the oil in order to clean the pickup screen while in the field? I am having low oil pressure issues on 6D compressor
@RefrigerationMentor2 жыл бұрын
I have always pulled and changed the oil to check, usually the oil was dark in colour anyway but I have friends who isolate the compressor full close suction, discharge and oil line as well as electrical safe the compressor and they put a vac pump on the crankcase. While in a negative pressure they pull it out quickly to check the screen than pull the compressor into a deep vacuum to get out any moisture. I have not tried this myself personally.

Great video. Trying to learn a little more about these. Going to look at one this week. I am getting it tripping on High oil pressure overnight. Any ideas what would be causing that? The compressor is actually low on oil although sight glass is very dirty and cant see for sure. Separator float may be jammed i suspect. Thanks
@RefrigerationMentor3 жыл бұрын
What is the oil pump pressures and the crankcase pressure? When it trips?
@RefrigerationMentor3 жыл бұрын
Intermittent oil warnings or a lockout is possibly a symptom of a plugged oil pickup screen. Symptoms of a plugged oil pickup screen is a return to higher oil pressure after the compressor starts again, followed by lowering oil pressure as the run time increases. If these symptoms are observed and other common causes of low oil pressure are ruled out (e.g. refrigerant dilution or low oil level), removal of the oil pickup screen to drain the sump and clean the screen will likely solve the problem. If the oil protection system is generating low oil pressure warnings or lockouts but the measured oil pressure is adequate…inspect the screen on the oil pressure sensor for debris.

@@RefrigerationMentor Oil pump pressure 75psig and crankcase 15psig when at set temp of -12.. on the controller inside it reads “high oil pressure” on the history but I suspect it may mean low or high as it’s only one 1/4” transducer. I am going to replace it to eliminate it. Check oil screen as you say. I may replace the separator as it’s a sealed one as a precaution. It is on a Copeland semi running a bread retarder it trips at night intermittent. Thanks again
