Condition Monitoring/Predictive Maintenance

PRÜFTECHNIK Condition Monitoring presents the VIBROWEB; a new, automated monitoring and diagnosis system for production-critical machines and systems.

VIBROWEB is completely autonomous, running without PC connection which makes it particularly suitable for applications in distributed and out-of-the-way machine parks (pump stations, pipelines,...).

The modular and flexible system configuration keeps investment and installation costs low and also enables the economic integration of VIBROWEB into existing monitoring infrastructures. VIBROWEB is designed to allow the logical connection of almost every type of sensor (ICP, DMS, LineDrive,...).

The signal conditioning for each channel is carried out with the aid of special plug-in cards that are simple to replace as and when required. Of the 32 analog measurement channels, two can be measured simultaneous, with other channels available for rpm measurements (8x) and for digital inputs and outputs (each 4x).

Unfortunately, when it comes to steam traps, people often ignore them.  There

A new variant of the MG4 has been introduced. Called MG4-Ref11, it has been developed for the pulp and paper industry for continuous monitoring of refiners.
 
Refiner disc segments getting in contact with each other cause the segments to break. Spare segments are expensive and the margin of error in this application is very small. This requires measuring equipment to be extremely fast. The MG4-Ref11 has been adapted to these requirements and has a measuring cycle of approximately 0.4 seconds for shock pulse measurements.

Since 2002, customers worldwide have avoided failures of their equipment, from vital production equipment to the office air conditioning, by using Artesis

Rustem Yildiz is maintenance manager responsible for the Gebze plant which supplies Daimler-Chrysler, Ford, Toyota and Honda on a Just-in-Time basis. From his office, he can access data on the current condition of all the equipment monitored by the Artesis MCM units, and is automatically notified of any changes in status, indicating a potential deterioration in performance.  In addition to the excellent downtime figures, he measures the success of the system by a significant improvement in his homelife, resulting from a dramatic reduction in the number of out of hours calls he receives, that previously had disrupted his evenings.

In his opinion, key elements behind the success have been:

Many organizations feel that if they can move from reactive to preventive maintenance they are headed on the right path, and that this in turn means they are on the road to proactive maintenance. However, as has been demonstrated by many studies, in excess of 80 percent of all failures are random. Therefore, time-based preventive maintenance (PM) programs will not be effective because you will, in most cases, be doing too much work too soon or too little work too late.

Over the past few decades, the demands placed on maintenance have been changing. In leading companies today maintenance is no longer viewed as a cost center, but rather is expected to contribute to the strategic goals of the company. In today

The DN36 Spyder range of machine monitoring and protection equipment and the SpyderNet plug in and play monitor are available from condition monitoring specialists Sensonics Ltd.

The complete DN36 family is line stackable to ensure rapid system integration/installation and minimal wiring requirements and can be connected to any Ethernet network to provide remote monitoring via standard Internet tools.  DIN rail mounting to either 35mm or G type DIN rails, ensures that monitors can be mounted in panels with other equipment or positioned locally in a junction box to the machine to be monitored.

Suitable for monitoring many types of rotating machinery, including turbines, motors, pumps and fans etc the complete DN36 Series offers dual channel monitoring, providing

Article Written By Idhammar Reliability & Maintenance Management Consultants.

Many reactive organizations conclude that RCA is the first agenda item for improving reliability. But after completing a few root cause activities, it's obvious that the results will point to already-known problem areas, such as inferior preventive maintenance (PM) and planning and scheduling. The initial reasoning to start an RCA initiative often follows this train of thought: We have a lot of equipment breakdowns, so . . . step one should be to analyze those breakdowns in order to . . . identify the root cause of the breakdowns in order to . . . eliminate the root causes.

It sounds logical and reasonable when presented this way, but if basic PMs and planning and scheduling aren't in place, most RCAs will point to these deficiencies. Typical outcomes of analyses fall on the wrong amount or type of lubrication, shaft misalignment, unbalanced equipment, missed inspections and overhauls. The "human" or "process" causes often relate to poorly planned work orders.
