Dear All, Could any one explain to me "what is the thermal study for centrifugal compressor? And who should do this study Vendor Or the end user? what is the function of this study? Thank you very much for your support in advance.

dear Artisi, THank you very much for your reply.Please check the replies. 2- accurately measured head. 3-voltrx"(vortex) plate": is a vertical plate on the suction of the pump it seems like to break the flow coming to the pump. 4- vibration analysis undertaken: the pump is too noisy. I will...

sorry please find attached the pump curve http://files.engineering.com/getfile.aspx?folder=88c32987-8b8f-43ea-ad95-ba1be4263047&file=027_41.pdf

dears all please find the attached pump data please your supporthttp://files.engineering.com/getfile.aspx?folder=c0b7cae6-b815-492f-8c00-94268e9abaf4&file=pump_data.pdf
