Process Equipment troubleshooting serial

Tip summary
• The objective of this serial is to provide engineers with easy to use root cause analysis maps that can help them to easily troubleshoot the plant equipment and restore the equipment quickly to the good operating condition to save energy & cost.
• In this video we will talk about gas moving devices especially Reciprocating-piston compressors troubleshooting.
• Reciprocating-piston compressors major problems root causes can be summarized in the following points
1. Valves and piston rings knocking possible causes:
• Frame lubrication inadequate
• Head clearance too small
• Cross-head clearance too high
2. Vibration possible causes:
• Pipe support inadequate
• loose flywheel or pulley
• valve LP unloading system defective
3 Discharge pressure high possible causes:
• Instrument error
• Valve LP unloading system defective
• Required system discharge high
4 Discharge pressure low possible causes:
• Instrument error
• valve LP unloading system defective
• LP valve worn
• System leakage
5 Discharge temperature high possible causes:
• instrument error
• LP valve worn
• Valve LP unloading system defective
• Required system discharge pressure high.
6 Cooling-water temperature high possible causes:
• Instrument error
• Water flow rate low
• Fouled area
• LP valve worn.
7 Valve temperature high possible causes:
• Instrument error
• Required system discharge pressure high
• Run unloaded too long.
• LP valve worn
8 Cylinder temperature high possible causes:
• instrument error
• Required system discharge pressure high
• LP valve worn
• Wrong speed.
9 Flow low possible causes:
• Instrument error
• LP valve worn
• Valve LP unloading system defective
• Dirty suction filter.
