I would appreciate advice from those experienced with screw chillers! Thank you

One of the full-liquid chillers in our factory that uses smoke cooling often experiences oil leakage. What are some effective methods for returning the oil to its proper place and for performing adjustments? I would appreciate more detailed information on this. I usually first switch back to manual mode, then reduce the load to 0 and adjust the supply valve, allowing the oil to flow back slowly over a period of about 2 hours. I’m not sure if this procedure is correct I’m not sure whether the oil has been completely returned to the evaporator. Usually, the vehicle can be driven once no oil is visible in the form of foam, but the oil in the separator gradually returns to the evaporator over 2-3 hours, which is very troublesome. I seek guidance from experts! Thank you, I’m in a hurry
I’m a newbie and don’t understand; please mark this as the top post
This has a lot to do with control. Factors such as the liquid level in the evaporator and the temperature of the circulating water can cause oil leakage. If there is oil leakage in our units, I usually increase the load manually to force the oil back inside, and this is done quite quickly
Expert upstairs. There is another method: short-circuit the return oil level switch to force oil return.
A full-liquid evaporator is prone to oil leakage; generally, an ejector pump is used to return the oil from the oil-poor area and the oil-rich area back to the suction line. What is the oil temperature when your machine starts up?
