Time is money and in a busy production environment, you want to ensure that downtime is kept to an absolute minimum to help maximise productivity – and profitability.
This is especially the case with your compressed air system. Over 10 per cent of all the electricity supplied to industry is used to compress air; an indication of the scale and size of the installed estate of air compressors across the globe. Operators are therefore keen to maintain maximum uptime of these ‘workhorses’ of modern production to ensure there is no impact to the bottom line.
However, any compressor system will require support throughout its working life, including routine, planned maintenance to protect equipment reliability and performance - especially in high-pressure applications, where production output is reliant on a continuous source of high-quality air.
The Carbon Trust estimates that around seven per cent of a compressor’s cost of ownership over a ten-year lifecycle is its maintenance. While energy costs will always remain the highest proportion of overall spend, this is by no means an insignificant sum and any maintenance improvements that can be realised will have a positive impact.
It’s not a new dilemma; striking the right balance between equipment operating hours, essential compressor maintenance and production demands is not a straightforward task. The question is not whether compressor servicing can be avoided, but how maintenance can be made simpler and therefore, quicker. It’s a question we are often asked at Gardner Denver – especially in relation to high-pressure compressor products which are often viewed as complicated and therefore, time-intensive to maintain.
Here’s our short guide to some of the areas to consider when investing in high-pressure compressed air systems.
The final high-pressure stage in any reciprocating compressor is a complicated assembly and the challenge for all manufacturers over the years has been to refine this design for longer component life and easier servicing.
It is an area that we have invested in for many years. Back in the 1990s, we moved away from metal piston rings running on cast iron bores with high pressure lubrication, to polymer rings running on other materials with minimal lubrication.
We've learnt a lot since then and have continued refining and evolving this technology to deliver ring and bore life far exceeding that of metallic ring designs, all in a very low lubrication environment.
Time is, indeed money. So much so, that one of our loyal customers literally put us to the test. Not with detailed analysis of compressor parameters or equipment uptime, but with a good, old-fashioned stop watch!
From hitting the stop button, to running again after a final stage piston, rings and valve change was just eight minutes!
That’s less than the time it takes for light from the sun to reach the earth or for the average person to take their morning shower!
Happily for you, if you invest in intelligent compressor architecture your machine can be back up and running in no time; without having to travel at the speed of light or even getting wet!
