Aandachtspunten vóór het doorspoelen van een turbine

Bij het gebruik van een stoom- of gasturbine is het belangrijk te bepalen of de apparatuur gespoeld moet worden. Het tijdig spoelen van een systeem verlengt de levensduur en zorgt ervoor dat de turbine optimaal blijft functioneren. het volledige potentieel ervan.

Wat is een spoeling?

Een spoeling is het proces waarbij de interne onderdelen van een turbine, of een andere machine, worden gereinigd met een vloeibaar reinigingsmiddel. Veel mensen denken ten onrechte dat een spoeling een eenvoudige klus is, maar zonder de juiste voorbereiding kan dit tegenvallen.

How to perform a successful flush

Performing a successful turbine flush is not as easy as it may seem. You will need to think carefully about the process before you get started if you want to do it successfully, otherwise you could cause more problems than the process solves.

A successful internal flush, according to ASTM D6439, is when:

“Clean pipe and system components are obtained in a minimum of time and with a minimum of effort.”

So, when performing a flush, your main aim should be to remove the buildup of old oil as quickly and cost-efficiently as possible. Here’s what you need to bear in mind if you want to achieve that:

High oil velocity

Ideally, you should use an oil velocity two or three times higher than your system’s normal working velocity if you want your oil flush to be a success. A higher velocity oil will very quickly remove any old oil that is lurking around in your system, so that you can start again with a clean slate. However, you should not use high oil velocity with certain very delicate systems, so it’s a good idea to consult the system manual, or someone who specialises in such matters, before you go ahead and clean your turbine.

Vloeistof

You also need to ensure that you use a fluid that will not react with the oil it will be flushing, because if both fluids are not compatible, particles that have the potential for damage could be left in the system following your flush.

Displacement fluid

Finally, once you’ve flushed the system, you will need to use a displacement oil to get rid of any excess cleaning fluid. Remember, to get the most benefit from flushing fluids, be sure to heat them first.
