Built-for-purpose fluid solutions, turbine oils are produced by leading lubricant manufacturers.
Turbine oils are designed to lubricate gas and air compressors, reduction equipment and hydraulic devices, but also key components like bearings and turbine runner hubs, among others.
In addition to the advanced lubrication levels, turbine oil also acts as an efficient coolant, and is designed to defend systems from issues like sludge build up, corrosion and rust.
Selecting the right lubricant for a turbine is crucial to guarantee optimum operating performance and extended equipment lifespan it is critical that you select the correct turbine oil for your needs. In this in-depth article we explore the selection process and help simplify the steps required for a successful product purchase
Understand the requirements of your turbine
Before any buying can begin, you must first familiarise yourself with your onsite turbine and any specific requirements that need to be met.
There are several factors to consider like turbine type – is it a hydraulic, gas or steam turbine? – and operating conditions like pressure, temperature, speed and load. You can also use the original equipment manufacturer (OEM) of your turbine’s guidelines for the recommended lubrication specifications.
Speak to lubricant experts
You can connect with lubricant manufacturers, suppliers and distributors with a reputation for expertise regarding turbine lubrication.
Such sources can offer invaluable guidance based on the requirements of your make and model of turbine, and make recommendations on the best suited lubricants available.
Lubricant base oil
Today, turbine lubricants are available that use either a mineral or synthetic base oil as the foundation of their formula.
Mineral-based turbine oils can work effectively under standard operating conditions and are often selected based on affordability, as they are a cost-effective product.
However, synthetic turbine oils can supply superior performance in applications involving extreme conditions, like extremely heavy load and high temperatures.
When selecting an oil, evaluate the advantages and disadvantages of standard and synthetic oils based on the conditions your turbine works under.
Turbine oil viscosity
Viscosity is a key characteristic of every lubricant, and the rule extends to turbine oils. It impacts whether the lubricant can form a suitable film and hold up under operating conditions.
Typically, the manufacturer of your turbine’s guidelines will specify an advised viscosity grade or range to aid your selection. However, always consider factors such as speed and load to choose the proper viscosity grade of turbine oil.
Turbine oil additives
Like many built-for-purpose lubricants, turbine oils often include additives to improve performance levels and prevent specific issues arising.
Commonly included additives include anti-wear agents, antioxidants, foam inhibitors and corrosion inhibitors. Make certain that the oil you select has the additives needed to answer the challenges faced by your turbine on site.
Assessing compatibility
Another key concern when picking a product is compatibility.
Ensure that the oil is designed to work safely and effectively with all the different materials used in your turbine’s components like bearings, gaskets and seals.
Incompatibility issues can quickly cause material degradation or impact operation. For guidance regarding compatibility, consult the OEM of your turbine.
Environmental considerations
If you are operating a turbine in an environmentally sensitive area, or your usage requires you to comply with legislation and regulations, be sure to choose a lubricant that answers all the environmental standards required.
When such circumstances concern your operation, compile your short list of possible lubricants from products that are biodegradable, have low toxicity and a reduced impact on the environment.
Maintenance and performance
Evaluation of maintenance requirements is important when finding the optimum turbine oil for your needs.
Look at condition monitoring and oil change intervals. Remember that oil with a longer active service life and effective monitoring can drastically reduce mechanical downtime and maintenance costs.
Selection also involves careful consideration of lubrication performance factors such as filterability, thermal stability and resistance to oxidation.
Adhering to OEM advice
Equipment makers usually supply detailed lubrication recommendations for the turbines they produce.
Keeping to the guidelines offered by OEMs will ensure you are compliant with the product warranty and will promote optimal performance from your turbine.
In contrast, ignoring OEM recommendations can void your warranty and result in sub-par performance levels.
Monitoring oil performance
After you have decided on a turbine oil, set up a dedicated lubricant monitoring programme. Regularly review and monitor the condition of the lubricant, turbine performance and results from oil analysis. You can adjust your lubrication strategy as and when required based on your findings to promote optimum turbine operation.
To sum up, selecting the correct oil for your turbine requires considering multiple factors, but consulting experts and using manufacturer guidelines can help you make the best decision and operate your turbine effectively.
