When the refining process pump failure may result in performance degradation during operation, or even the entire plant outage, if one also involves flammable or hazardous fluid, then the health and safety staff will be seriously threatened, The site will also face environmental investigation and penalties.
Even if there spare pipeline pumps can not cope with the sudden failure of these accidents. Shishi Shang alarm signal has always been there, just need to identify and notify to the relevant staff to take appropriate measures,glue stick so the critical process equipment for automatic monitoring program is very necessary.
For example, a few years ago a large oil refinery have built a high-speed centrifugal pump bearings suddenly jammed, resulting in the production suffered serious losses, and produce high maintenance costs. Failure due to lack of bearing lubrication, resulting in bearing temperature is too high.
4 months ago, we installed the pump is a mechanical device status Emerson transmitter, this failure to obtain prior to the prevention, detection and, when the automatic monitoring and analysis of the motor pump group issued a series of alarm systems, factory Operators will receive timely information. Electric pumps are prone to failure,glue gun but we can use the device status analysis a few days before the failure occurred, there is plenty of time to take measures to prevent major accidents. Trend was the status of equipment within 10 minutes rapidly from 60 to 0, so that the factory had no time to take any measures to prevent failures from occurring, if the earlier state of machinery and equipment by Emerson transmitter, the result is not the case.
Pump motor pump can be found in other similar fault trend templates can be used as vibration analysis system for automated analysis of a model. Each device will be subject to continuous scanning surveillance to detect bearing misalignment, pump cavitation, and the motor electrical fault and so on. Emerson Smart machinery and equipment by state management system, continuous vibration monitoring and intelligent microprocessor-based diagnostic instrumentation and advanced software and communications functions combined with the state of the automatic diagnosis of rotating equipment.
Some important pumps, due to cost factors, not by way of their automatic monitoring of cable, you can use Emerson's wireless vibration transmitter CSI9420 and intelligent wireless network to obtain accurate vibration data. Emerson's wireless solutions extend the PlantWeb digital plant architecture features that make mobile information access to new information and possible decisions to improve the plant's capacity and operating performance.
Smart Wireless field solutions to wirelessly integrate smart monitoring instrument self-organizing network, when you add and remove devices, or obstacles, the network will be automatically adjusted, so that the reliability of data transmission up to 99% or more. Emerson's Smart Wireless products meet IEC62591 (WirelessHART) standards.
Important or critical pump automatic monitoring process will enable control room operators and maintenance personnel informed of device status information in a timely manner, as a preventive measure. Therefore, monitoring programs can be used to avoid the automatic pump operation, safety, environmental and other related accidents, improve the operation of the refinery reliability and profitability.
