Case Study on Advantages of Proper alignment of Rotating Machinery Assemblies

Hi,

Good, within tolerance, mechanical alignment between the driving motor and driven components is one of the basic health requirements.

I came across an excellent case study for which the link is given below.

Proper alignment helps one plant keep on pumping.

Good vibrations – Bad vibrations – Back to Balance

Hi all,

Years spent operating and maintaining marine gas turbines on ships have left me very sensitive to the issue of bad vibrations. The salt-laden humid sea air entering the compressor section of the marine gas turbines leave salt deposits on the blades. If not attended to regularly, the deposits will tend to foul the air flow and lead to something known as “Compressor surge”, that leads to air flow becoming disturbed and oscillating from and to the turbine end. This surge can cause catastrophic failure of the turbine as a whole, due to the sporadic and violent directional changes in axial loading on the bearings.

Taking another type of equipment this time; High speed exhaust blowers connected to automobile paintshops tend to collect paint sludge and vapour condensation on the blades over time. This causes imbalance to the rotor and leads to bad vibrations. If not corrected in time, premature bearing failure and catastrophic damage to the equipment can occur.

I came about a well written article in the recent edition of Plant Services e magazine. The link to the article is given below.

Mechanical Maintenance Practices

Hi all,

In the maintenance field, alignment check of dynamic equipment plays a very important role. So does lubrication of moving parts. While browsing around for good articles on such maintenance topics, I came across the linked article that gives good insights on reasons for failure, remedies and other recommendations.

Control Harmonic Distortion to Reduce Energy Consumption

Hi all,

After a short gap I was going through the Plan Services Web page and found this informative article on how to control harmonic distortions and achieve energy consumption reduction. As a bonus, we can get extended life for our equipment such as motors and drives.

Please read and be enlightened.

Motor Management Can Reduce Repair Costs by 50 Percent

Hi,

The facilities infrastructure that we maintain use a large number of motors of various capacities and types in many types of applications. In fact without electric motors that convert electrical energy into mechanical energy, most of our work will not get done. Thus motors are one of the largest energy consumers in any infrastructure set up.

This would mean that any energy conservatioin programme should definitely look into optimum utilisation of motors through periodic maintenanance and operations management. The linked article is from the February 2010 issue of Maintenance Solutions magazine. The article is in three parts.
