Seeking help regarding the oil circuit of propylene refrigeration compressors
Thread Content
As shown in the figure, this is the compressor of an acrylic refrigeration unit; the oil returns to the compressor after passing through an oil separator, a cooler, and a filter. Why is it necessary to divide it into so many streams? What is its function? Enthusiasm will surely earn extra points.
This is the compressor diagram for York
Oil supply throughout the process, load adjustment, fuel injection by the units, and bearing lubrication
Load regulation, oil circuit cooling, seal cooling, etc
Could you indicate on the diagram the specific pipelines corresponding to each function? And do the so-called slide valves refer to those sets of pipelines used for load regulation? How does it exert a regulatory effect? Thank you
SB2 and SB3 are the two lubrication points of the unit; SC1, SC2, and SC3 are used for adjusting the load, ranging from 10% to 110%. The SC8 solenoid valve is responsible for returning oil. SM1 is the manual valve for the oil circuit during startup. This unit does not have a lubricating oil pump. The oil-gas mixing point is located at the top of the diagram you have – the screenshot does not show it in its entirety. In front of the HV401 angle valve, this unit uses double-end mechanical seals; any seal leakage returns to the unit’s inlet, and no flushing is provided. That’s basically it
