Fluid Contamination – The Silent Thief

10th August 2016 • By

Fluid contamination is a leading cause of slower performance, erratic operation, lost productivity, higher operating costs and catastrophic failure of Machines. This video, “Fluid contamination – The Silent Thief,” details the importance of following strict procedures and guidelines to keep your engines and components clean so you can maximise machine productivity and component life.

Digging Up a Solution to Fluid Contamination Control

23rd June 2016 • By

The Problem
Mobile mining equipment hydraulic systems are typically exposed to very high solid particle ingression rates. A mine was experiencing premature component failure on its excavator due to high particle contamination. In the first 27 months of operation, costs included four variable speed piston pump replacements ($20,000 per exchange, $34,000 new), three swing motor replacements, two drive motor replacements, numerous servovalve repairs or replacements, 42 hydraulic hose-related problems, and 16 instances of contamination sensors requiring cleaning. The oil was highly contaminated, yielding excess oxidation after 2,255 service hours and needed to be replaced. Other associated costs included excessive unplanned equipment downtime, more than 39 hours, and unplanned maintenance costs.

The machine was not operating reliably and was approaching the end of the warranty period. The goal was to eliminate premature pump and servovalve failures, minimize costly component repairs or replacements, and increase the overall productivity of the operation. The shovel is the critical piece of equipment in the mining process. When the shovel is down, several haul trucks are also down and no coal is being produced.READ MORE

Everyone Is Looking For A Short Cut

Revolutionise the Way you Think about Oil

All Lubricants are the same right? Just select the the cheapest oil of the right viscosity grade and the rest is history. Right…? Wrong!

Not all lubricants are created equal. I am a great fan of Synthetic Lubricants. They are well worth their salt, as the savings that they produce go way beyond the cost of the lubricant. However there is more to a lubricant than just it’s Base Oil.

Some lubricant blenders such as Revolution Oil have taken it further by sourcing cutting edge additive technology, which is unmatched in today’s market, giving lubricants a film strength 4 times greater than any other on the market and an extended oil life factor of at least 2 and in some case 24 times. Among these benefits are a raft of others.READ MORE

Diesel engine’s injector failures

26th August 2015 • By

Injector failures is something that is not always monitored. We have a failure, decide whether it is a warranty case or not and book it to the breakdown cost subjected to the machine. However, there is a hidden cost compiling from each machine’s injection system that is not measured. Every machine has a specific load it can carry and it has to carry that load at a specific time interval over a distance. If the machine has a loss of engine performance, it effects the production capability of the machine and therefore a loss in production over time. We therefore have to cases, a ‘catastrophic’ failure of the injection system and the functional failure of the injection system.

With the ‘functional’ failure the injection system can no longer operate at its designed specifications. This causes a loss of engine performance, higher fuel consumption and an irregular spray pattern which can ultimately lead to breakdown.
