Conditioning monitoring

Electric motor workshops and repair services are critical components within an electrical company, focusing on the maintenance, repair, and optimisation of various electric motors used across industries.

The condition monitoring technologies and services that we offer include:

Vibration Analysis

Kenshaw offers vibration analysis of your rotating assets utilizing modern equipment and highly trained skilled technicians to identify and recommend corrective actions necessary to keep your plant operating at peak performance.

With the implementation of a routine vibration analysis program the following benefits are possible:

• Identification of issues prior to expensive plant downtime and loss of production
• Positive prioritisation of required maintenance to maximise maintenance efforts and resources
• Reduction of damage to secondary and ancillary equipment
• Improved plant reliability and production

Reports list the condition of the plant surveyed in a clear and easy to understand format. Plant requiring corrective actions have a detailed fault analysis and description with required recommendations.

Grease and oil sampling, on-site balancing, motor diagnostics, laser alignment and thermography services are offered by Kenshaw to complement vibration analysis programs.

Positive identification of the following problems can be achieved with vibration analysis:

• Rotating component imbalance
• Mechanical looseness
• Bearing defects
• Gear mesh problems / defects
• Misalignment of components
• Lubrication issues
• Pump cavitation
• Electric motor problems

The oil becomes a working history of the machine.

Particles caused by normal wear and operation will mix with the oil. Any externally caused contamination also enters the oil. By identifying and measuring these impurities, you get an indication of the rate of wear and of any excessive contamination. An oil analysis also will suggest methods to reduce accelerated wear and contamination.

The typical oil analysis tests for the presence of a number of different materials to determine sources of wear, find dirt and other contamination, and even check for the use of appropriate lubricants.

Oil Analysis

Oil analysis involves sampling and analysing oil for various properties and materials to monitor wear and contamination in an engine, transmission or hydraulic system.

Oil analysis can detect:

• Fuel dilution of lubrication oil
• Dirt contamination in the oil
• Antifreeze in the oil
• Excessive bearing wear
• Misapplication of lubricants

Some wear is normal, but abnormal levels of a particular material can give an early warning of impending problems and possibly prevent a major breakdown.

Sampling and analysing on a regular basis establishes a baseline of normal wear and can help indicate when abnormal wear or contamination is occurring. Oil analysis works like this. Oil that has been inside any moving mechanical apparatus for a period of time reflects the exact condition of that assembly. Oil is in contact with engine or mechanical components as wear metallic trace particles enter the oil. These particles are so small they remain in suspension. Many products of the combustion process also will become trapped in the circulating oil.

Laser Alignment

Kenshaw offers laser alignment services that are fast and extremely accurate.

Using laser alignment systems, our technicians provide a comprehensive shaft alignment measurement service for your rotating assets. Whether you have complex drive trains, vertical machines, or any number of simple pump and motor sets to align, in standard or hazardous environments, Kenshaw can provide a cost effective, professional service for your company.

The laser alignment systems utilised by Kenshaw are calibrated to applicable standards which enable both accurate and repeatable measurements.

Detailed reports are provided that clearly show, both graphically and numerically, the original and final alignment condition of the drive train components.

Plant reliability starts with accurate alignment.

When misaligned, the loading of the drive components dramatically increases due to the rotational reaction forces.

This increased loading can lead to:

• Premature bearing and seal failures
• Premature bearing and seal failures
• High bearing temperatures
• Lubrication problems
• Excessive vibration
• Damage to component mountings
• Increased power consumption

Dynamic Balancing

Kenshaw offers on-site balancing services.

The benefits of on-site dynamic balancing are:

• Reduction in downtime, no disassembly and removal of components off site
• Can be carried out during short planned outages effectively
• Extends the service life of bearings, seals and machine components
• Product quality maintained with increased productivity

Typical equipment / components that are balanced on site include:

• Pulleys and rollers
• Couplings
• Pump impellors
• Blowers and fans
• Large rotors

We come to your facility and carry out balancing on your assets. Typical industries utilising our on-site balancing services are:

• Cement Plants
• Pulp and Paper Mills
• Power Utilities
• Water Utilities
• Steel Mills
• Materials Handling Operations
• Manufacturing Sector
