Wireless condition monitoring system for petrochemcial industry

Wireless machine vibration and temperature monitoring system for pumps, fans, compressors, etc

Data transmission

Collect pump operation vibration and temperature via wireless sensors installed on machine surface, data process is done in wireless sensor, then send data to field wireless data collector via Zigbee. Wireless data collector send data to workstation server via enterprise ring network or wireless method (WIFI, 3G, 4G).

Alarm reminding

Intelligent alarm selects abnormal data precisely and sends reminding via short messages, emails or APP

XX refining catalytic workshop (vibration over-range) P205/A/3H/16K acceleration (2-15K) Level 4

Process

1)Alarm verification by remote diagnosis staff: true;

2)Data analysis by remote diagnosis staff: acceleration amplitude increased suddenly, waveform has frequency disturbance, bearing cage has tightening force. Rotating components have looseness and wear.;

3)Submitting conclusion by remote diagnosis staff: Pump driving end bearing cage broken, bearing lap suddenly, looseness and wear existed in bushing, lubricating failure;

4)On-site staff receives the diagnosis conclusion. According to diagnosis suggestion and on-site situation, trigger for work flow.

Solution and suggestion

Client: shut down the machine, mainly check pump driving end bearing cage and inner race wear, check bearing bushing wear and change if necessary

Remote diagnosis staff: track overhaul result, verify the result via machine start up data
