Predictive maintenance data acquisition system for petrochemical engineering

Abstract

The invention relates to a predictive maintenance data acquisition system for petrochemical engineering. The system is used for monitoring a petrochemical engineering instrument control device, the petrochemical engineering instrument control device comprises a plurality of cabinets, a plurality of pipelines, a plurality of circuits, a plurality of instruments, a plurality of control systems and aplurality of valves, the circuits are provided with grounding terminals, and comprise a monitoring platform, an on-line real-time detection part and an off-line detection part, the on-line real-timedetection part comprises a leakage detector, a signal collector, a transponder, an instrument alarm and a controller alarm, and the off-line detection part comprises an infrared temperature detector and a grounding loop resistance test meter. Each leakage detector, signal collector, transponder, instrument alarm, controller alarm, infrared temperature detector and grounding loop resistance test meter are connected with the monitoring platform. By adopting the scheme, the predictive maintenance data acquisition system for petrochemical engineering can comprehensively monitor pipelines, circuits, instruments, control systems and valves.

Description

technical field [0001] The invention relates to the technical field of petrochemical monitoring, in particular to a predictive maintenance data acquisition system for petrochemicals. Background technique [0002] The petrochemical industry is my country's pillar industry. It is mainly engaged in the production, refining, chemical industry, storage, transportation and sales of crude oil and natural gas. The petrochemical industry belongs to the hazardous chemical industry. [0003] The petrochemical instrumentation and control device is used for the status monitoring of production equipment, the optimal control of production operation, and the realization of safety interlocking functions. It is the eyes and soul of production and storage and transportation devices in the petrochemical industry. An important guarantee for operation, the petrochemical industry’s production units are currently running for a long period of “every four years” and face huge challenges such as unpl...

[0003] The petrochemical instrument control device is used for the state monitoring of production equipment, the optimization control of production operation, and the realization of safety interlocking functions. It is the eyes and soul of the production and storage and transportation devices in the petrochemical industry. An important guarantee for the operation. At present, the long-term operation of the production equipment in the petrochemical industry is "repaired every four years" and is facing huge challenges such as unplanned shutdowns caused by equipment failure and damage. It also brings high maintenance costs to petrochemical companies. However, petroleum The chemical instrument control device itself lacks its own health status monitoring. Once there is a problem with the petrochemical instrument control device, the operation of the petrochemical device will be out of control, and it is very easy to catch fire and explode, which seriously affects the safety, environmental protection and quality of petrochemical manufacturing.
