![]() If you think I am wrong about anything I say, then please do correct me, but please also refrain from condescending lectures to myself and others here, in the preschool level details of chem, math and physics. When the lower pressure compressors can not reach higher pressures of the 7barg compressor, the NRVs close and the 7bar compressor tops off the receivers at 7 bars.Ĭan you please take the 7 barg compressor offline and let us know what the gages read then. The gage pressures are slightly higher than the compressor setting because the compressors have to work a bit harder to try to keep up with the 7bar compressor. The gages are reading pressure delivered at each compressor's discharge, not header pressure, because the gages are upstream of the NRVs. Any logic that drives E and W should hold the signals high with a power-on reset. Still a good answer.īut I think could be what I thought, The 7 barg Compressor is always topping off. LittleInch, Maybe I have to take your star away. RE: Compressor and Receiver Pressure issue 1503-44 (Petroleum) 1 Jun 21 09:23 If there is any data needed, please let me know. The media is air and each compressor set point measures the value at the individual compressor discharge before check valve. Is there any logic for this reverse scenario happening? ![]() Generally, when there is a pressure drop, the compressor side which is the generating end should be having higher pressure and receiver should have lower pressure. AnyLogic is the leading simulation modeling software for business applications, utilized worldwide by over 40 of Fortune 100 companies. When we start the compressors with variable setpoints for all compressors 7 bar max pressure for one of the compressor, all the compressors which are in load condition at that time, are showing a pressure reading of 6.5 to 6.4 bar when in load condition, whereas receiver is showing a pressure of 7 Bar constantly, we have two receivers connected in parallel to discharge header of all 4 compressors. We have continuous variable demand downstream of receivers from 5000 SCFM to 1500 SCFM. Parameters of income and group communication are analyzed in the later. ![]() We have 4 screw compressors of approximately 1200 SCFM, one compressor on VFD. legal information activation guides version history system requirements. Then Anylogic 6.5.0 is used to implement this multi-Agent simulation model. ![]()
