An on-line real-time relative dissipation factor monitoring system

An on-line monitoring system of hydrodynamic lubricant supply conditions for the back-up roll’s oil film bearing of 1420mm cold rolling mill was developed for providing real time monitoring so as to avoid unexpected breakdown of the production line. The monitoring parameters of supply pressure, supply temperature and supply flow rate show that the monitoring system software with real-time event trigger mechanism and intelligent storage algorithm solves the issue of data overflow in the continuous record and ensure the safety of data transmission. Test results for hydrodynamic lubricant supply conditions in the industrial production are reported, which indicated that established software architecture and programming methods construct a stable and reliable monitoring system, which provides early warnings for the safe production.

Hydrogenation Reactor

A life monitoring and assessment system of pressure vessels and piping in petrochemical plants has been developed based on the structural integrity theory and web technology. Two industrial cases of the monitoring system are given in this paper for hydrogen processing reactor, hydrogen pipeline and furnace tube of hydrogen reformer. The monitoring system is established to predict hydrogen embrittlement for the wall materials of hydrogenation reactor and pipeline in petrochemical plants. A critical description of hydrogen induced cracking is introduced to set up a criterion for the embrittlement. The electrochemistry hydrogen sensor is designed for its feasibility of real-time monitoring and assessment of hydrogen embrittlement for the equipment. It is pursued by the research to make a more impersonal judgment of safety of the hydrogenation reactor with real time tracing of operation. A remote inspection system is created based on computer network technology to monitor the plant subjected to hydrogen attack. The on-line system is also founded to monitor the operation of the furnace tube of hydrogen reformer and predict its residual life. The system executes in the remote server to assess the life of the tube and issue the information through the internet. Therefore remote users can monitor and manage the tubes on real-time. A non-contacting temperature monitoring technique is introduced into the system using CCD camera. An assessment method is introduced in this paper to create a correspondent relationship between remaining life and damage accumulation. It is significant for the method to describe the tube damage or materials degradation under unstable operations including varied pressure, varied temperature, over-heat or thermal fatigue, etc. A life fraction model related to damage accumulation is adapted into a real time monitoring system to calculate the residual life for a selected tube and work out an optimum preventive maintenance project.

Experience has shown that RTC systems are vulnerable to failures in the on-line monitoring system. It is therefore crucial to have a small and well functioning monitoring system than a larger monitoring system with many failures. This paper describes the results of a project with the aim of investigating the on-line monitoring system 4 years after put into operation. The outcome was a cut down in the number of on-line level transmitters and an automatic routine for detecting failures in the level transmitters. The routine has been programmed into the SCADA system and checks for 15 commonly occuring errors. Furthermore, an automatically generated report prints out statistics for larger rain events.

Blade Tip

A fiber optic laser probe based system is described for real time monitoring of flutter in rotating turbomachinery. The digital flutter monitoring system is designed for continuous processing of blade tip timing data at a rate of 10 MB/s. A USB2.0 interface provides un-interrupted real time processing of the data. The blade tip arrival times are measured with a 50 MHz bscillator and a 24-bit pipelined counter architecture. A graphical user interface provides on-line interrogation of any blade tip from any light probe sensor. Alternatively, data from all blades can be superimposed into a single composite scatter plot displaying the vibration amplitude of each blade. A hardware platform was developed to simulate a seventy two bladed turbine operating at 15,000 rpm. Blade tip responses from three light probes were generated in an infinite loop, providing reproducible and controlled conditions for testing the vibration monitoring system. Time interval measurements were consistently made with a single count error in a 24-bit count vector. Real time testing was done using a two blade rotor mounted in an evacuated chamber at the Spin Rig Facility at the NASA Glen Research Center. The shaft in this facility was suspended by two radial magnetic bearings and the nonsynchronous vibration was communicated to the blades through the magnetic bearing. The shaft motion was much smaller than the blade vibratory amplitude, realistically simulating flutter vibrations. Nonsynchronous vibratory amplitudes for the first mode were of the order of twenty mils and for the second mode of the order of a few mils.
