A practical example involves a recent project at a wastewater treatment plant in Cleveland that needed realistic cold alignment targets for a 3600 rpm compressor.

This machine had a long history of coupling and bearing failures. Over a two-year period several attempts were made to calculate the thermal growth on the motor and compressor supports. The original equipment manufacturer's (OEM) technical manual gave a vertical thermal offset value of +0.04 in. (+40 mils). There were no recommendations for a target vertical angularity. Horizontal alignment changes were not mentioned.

There was some confusion with the OEM targets as provided. Maintenance personnel did not know if this value represented what the rim dial indicator should read when the cold alignment was completed (with a dial indicator mounted on the stationary shaft and indicating the motor coupling). Dial indicators indicate the total indicated runout (TIR) each time the shaft is rotated 180 deg. Half of the TIR represents the actual centerline offset; therefore the target should actually be +20 mils vertical offset.

In the medical community, prescription without diagnosis is known as malpractice. In compressed air, a solution without problem definition is guessing. Everyday, facilities personnel commit compressor malpractice by responding to a symptom instead of
discovering the real problem. A symptom may be low air pressure,which is certainly a problem to production, but the root cause of the low air pressure could be any number of reasons.

When sensor market leader ifm electronic launched the efector metris a year or so back it caused quite a storm as the first affordable device to monitor consumption or leakage of that major commodity, compressed air.

Many of you use other gases, though, and we were often asked

Cost-effective predictive maintenance vibration monitor detects rolling element bearing failures and shaft imbalance conditions in four locations simultaneously.

The innovative efector octavis bearing condition monitor from sensor market leader ifm electronic is now available as a master unit which can monitor up to four seaparate locations.   These new versions make predictive maintenance efector octavis even more cost effective.

The octavis central unit can also now be programmed via ethernet. The vibration pickups, which can be up to 30m from the central diagnostic, are made in stainless steel with a IP69K rating  for arduous environments.

At Maintec 2008 ifm electronic will be showing two innovative products aimed at optimising energy usage and plant efficiency: the efector metris and efector octavis.

The efector metris compressed air flow monitors from sensing expert ifm electronic, provide a convenient and cost-effective way of monitoring compressed air consumption, making it easy for users to ensure that this expensive resource is utilised efficiently.

The efector octavis sensor detects damage to rolling element bearings at an early stage. This allows optimisation of vital plant availability from gears, to electric motors, ventilators, pumps and increases production efficiency.  NetMonitor centralises the information gathered.

The seminar will consist of 3 different workshops.  Delegates can select the workshop they wish to attend.  Each Workshop will be approx 3 hours.

09.00 -  Introduction to MCP Consulting and Training 

09.30-12.30 Workshop 1 - Reducing Costs through effective asset management in a manufacturing environment
Cost reduction is no longer just about reducing staff numbers, the focus has to be how to get more with the same.  Equipment efficiency in many organisations is still very low with utilisation levels of 50-60%. 
Equipment performance is not just the responsibility of the engineer, all production staff have a role to play.  In this workshop we will consider how equipment performance can be improved, costs reduced and inefficiencies eliminated.
Workshop topics will include:
