Fault Diagnosis System for the Variable Volume Pressure Filter

Abstract Fault diagnosis has been studied very actively during recent years. Increasing availability and minimising service costs are the main objectives for the fault diagnosis of process equipment. A high degree of availability and ease of maintenance and repair gives a competitive edge to the manufacturer. This paper presents the fault diagnosis module of the intelligent control system for the variable volume pressure filter. The system is capable of detecting the faults of the process and the equipment. The fault diagnosis system is integrated with the control system of the filter and works in parallel with it. The aim of the system is to indicate the undesired or forbidden process states and to take appropriate actions in order to maintain the optimal operation.

Operator Support System for the Larox Pressure Filter

Abstract Artificial intelligence methods such as expert systems, fuzzy systems, neural networks and combinations of these, have become invaluable tools in helping operators to monitor and control processes. These methods can also be used to run processes in a more economically effective way and, in the case of equipment malfunction, they can propose appropriate corrective measures. In this paper an operator support system for the Larox pressure filter is presented.

An intelligent, integrated control system for a pressure filter

Artificial intelligence methods like expert systems and self-organizing maps have proved to be excellent tools for the control of mineral processes. This technology is currently being embedded directly into process equipment like flotation cells and dewatering filters. In this paper an intelligent, integrated control system for a pressure filter is described and the testing results presented and discussed.

Remote Support System for a Pressure Filter

Abstract Fault diagnosis and remote support systems have been studied very intensively in recent years. Increasing availability and minimising the service costs are the main objectives for the remote diagnosis of process equipment A high degree of availability and ease of maintenance and repair gives a competitive edge to the manufacturer. In this paper, various remote support systems on the market are first discussed. Then the intelligent control system for the variable volume pressure filter is presented. The main emphasis is on the discussion of the fault diagnosis module, and especially its remote support features.

Fault diagnosis and remote support system for the variable volume pressure filter

Abstract Process equipment manufacturers are looking for added value for their products by implementing intelligent automation. Fault diagnosis and remote support for process equipment increases safety and reduces maintenance time and repair costs. This paper presents the fault diagnosis module of the intelligent control system for the variable volume pressure filter. The fault diagnosis system works in parallel with the existing automation system. The system is capable of detecting faults in the process and equipment, indicates the undesired or forbidden process states and suggests the appropriate actions in order to maintain optimal operation. The experimental results of the fault diagnosis system for the filtration and pressing stages of the filter are presented and discussed.
