High Temperature Monitoring using 3300/30 or 3300/35 6-channel Temperature Monitors or 3300/36 2-channel Temperature Monitors
There are additional temperature measurements that should be continuously monitored to detect various machinery problems. High cylinder discharge temperature is a common measurement on reciprocating machinery and is normally used as a machinery shutdown parameter. It can give an indication of coolant failure or of a potential failure associated with piston ring wear or discharge valve failure. High crosshead slipper and crankshaft main bearing temperature can indicate problems related to fluid-filmed bearings, including overload, bearing fatigue or insufficient lubrication. High cylinder packing temperature can warn you of leaks or loss of lubrication in the cylinder packing. It is commonly used when the pressure in the cylinder exceeds 500 psi, when the process gas is hazardous or on liquid-cooled packings.
Bently Nevada recommends machinery shutdown on high cylinder discharge, high main bearing, high crosshead slipper and high cylinder packing temperatures.
Bently Nevada offers the 3300/30 and 3300/35 Six-channel Temperature Monitors and the 3300/36 Two-channel temperature Monitor for temperature monitoring using either thermocouples or resistance temperature detectors (RTDs). Measuring temperatures at these critical locations and correlating them with other process variables can assist in determining the overall condition of reciprocating compressors.
Machinery Management
The best way to manage your reciprocating compressor’s condition and to conduct root cause failure analysis is to send all collected data and appropriate process information into Data Manager® 2000 for Windows NT. With this data, Bently Nevada’s Performance ManagerTM 2000 can also monitor the parametric performance of your reciprocating compressor.
