On-line monitoring system and monitoring method for machine-pump group status

Abstract

The invention relates to an on-line monitoring system and monitoring method for the state of a machine pump group. The monitoring system includes a plurality of machine pump state sensors, several machine pump state data converging devices, and an industrial computer as a monitoring terminal. The machine pump state sensors correspond to each other one by one. Each pump state data collection device is wirelessly connected to a plurality of pump state sensors, and the pump state data collection device is connected to the industrial computer wirelessly or with wires. The monitoring method is that the vibration and temperature information of the pump is collected in real time by the pump state sensor, and wirelessly transmitted to the pump state data aggregation device. After centralized processing, it is then transmitted to the industrial computer. After calculation and processing by the industrial computer, the display computer The real-time status, historical operation status and fault diagnosis report of the pump realize the online real-time status monitoring of the pump by the monitoring center, which facilitates timely detection of faults and timely processing to ensure the normal production of the enterprise.

Description

technical field [0001] The invention relates to a monitoring system, in particular to an on-line monitoring system and a monitoring method for the state of a machine-pump group in a petrochemical enterprise to monitor whether the machine-pump group is working normally. Background technique [0002] Due to the characteristics of the process technology in the petrochemical industry, the equipment is in a high temperature and high pressure environment, and it is necessary to apply real-time status monitoring methods to achieve management. Real-time status monitoring is an important part of strengthening the professional management of large units in the petrochemical industry, which directly reflects the operating status of the units. At present, the focus of online monitoring in domestic petrochemical enterprises is often quite critical large-scale units, such as the main fan unit and air pressure unit of the catalytic cracking unit, the air compressor unit of the power worksho...

AI Technical Summary

Problems solved by technology

[0003] The invention mainly solves the technical problem that the original petrochemical enterprises still stay in the stage of offline monitoring or manual inspection and regular maintenance for small key rotating equipment, and cannot realize online real-time state monitoring, which affects the normal production of the enterprise; it provides a machine-pump group state The online monitoring system and its monitoring method can collect the vibration and temperature information of the pump in real time, automatically diagnose the fault of the pump, display the real-time status, historical operation status and fault diagnosis report of the pump on the monitoring terminal, and realize the Online real-time monitoring of group status facilitates timely detection of faults and timely processing to ensure normal production of the enterprise
