To keep your turbine running smoothly, you should maintain your machine’s tools and oil just like pencil grinders (electric) – air turbine tools. These are just a few of the tools you will need to keep your turbine tip-top shape. This article will go over lubricant needs, component inspection, and proper oil application. Keeping track of inventory is also important for turbine companies. Using inventory management software, you can keep track of the parts you have and when they need to be replaced.

Preventive maintenance for wind turbines

To extend the lifespan of a wind turbine, operators are adopting preventative maintenance strategies. These maintenance practices include cleaning, adjustments, lubrication, and repair or replacement. Preventive maintenance for wind turbines uses sensors to record and analyze the condition of the assets. These preventative maintenance services are typically performed several times a year with the help of computerized maintenance management software that records previous service history and automatically sends reminders when maintenance checkups are due. Preventive maintenance for wind turbines is beneficial in predictive maintenance since it involves using sensors to monitor the health of key components and send valuable data to the maintenance team. This data may include vibration, temperature, foundation displacement, and lubrication levels.

Data-based predictive maintenance methods are becoming increasingly popular in wind farms. These technologies use data from sensors to detect problems early. This data includes vibration, temperature, and foundation displacement, which help technicians plan maintenance. For example, excessive vibration in a turbine’s shaft might indicate that it needs realignment. The engineers can determine when to visit and remotely set performance parameters with predictive maintenance. They can then assess whether these issues require maintenance or not.

Inspection of components

While working on an air turbine, there are specific components that you need to inspect. Specifically, you should look for cracks in the blades and nozzle vanes. Cracks on the blades should be detected by visual inspection. You may also use structural inspection techniques to help you locate cracks. When checking for cracks, make sure you don’t have cracks that extend past the blade’s outer shroud. If the shroud is less than a specified thickness, you must replace the blade. A typical inspection requirement is shown in Figure 4. Blades with slight nicks are acceptable as long as they are not sharp and the trailing edge is not more significant than the allowable area.

ECT is most effective for structural component inspection. It can identify near-surface defects that are difficult to see with other methods. The extent of defects is determined by the material composition, temperature fluctuation, and stress. Eddy Current Array (ECA) is another effective tool for defect inspection. It allows analysts to see defects that are hard to detect with a visual inspection. The device can be used in various locations, including up towers, wind turbines, and aircraft parts.

Oil change

One of the most critical things to remember when air turbine tools are the regularity of oil changes. The best time to change air turbine oil depends on your specific requirements. For instance, if your air turbine tools use a single-phase oil, you will need to change it more frequently. Similarly, if you use two-phase oil, you will need to change it more often. Both types of air turbine tools require oil suitable for a particular application.

There are several ways to do it when changing oil for wind turbines. One of them is to follow the manufacturer’s recommendations. Some turbines require oil changes after a certain number of years. For example, changing the oil every year after your turbine’s warranty expires will increase the lifespan of your tool. Another method is to change the oil after critical deviations have occurred. Finally, you can change the oil much more quickly and efficiently by using a mechanical device.

Grease application

Proper grease application is essential for operating a piece of large industrial equipment or a small home air turbine. Unlike cars, which frequently start and stop, wind turbines are constantly in motion. As a result, starting and stopping conditions can vary greatly, especially in cold climates, and grease can quickly degrade. Similarly, because wind turbines tend to be more slow-moving than cars, their lubrication needs are different than that of automobiles.

Many grease formulations rely on polymers or thickeners to provide optimum performance across various properties. In some cases, however, this approach can interfere with the grease’s ability to release oil during operation and can hurt its low-temperature performance. In such cases, grease formulations that focus on the oil and thickener working separately may be more effective. But, again, a balanced approach to testing will ensure a grease’s performance in the field.

Inspection of bolts

When installing wind turbines, technicians need to ensure that the bolts are securely tightened. Conventional methods require technicians to tighten each bolt individually, taking days manually. An innovative solution developed by the Danish wind turbine tools R&D team, the Bolt-Check, significantly reduces the time required for the task. This innovative tool measures bolt tensions without removing them from the turbine. It also eliminates the need to repeat tensioning operations.

To perform this task, technicians need to check the load on a specific percentage of the bolts. However, OEM specifications may require testing 100 percent of the bolts. Bolt-Check offers an efficient solution to this problem. It combines mechanical measurement with ultrasonic length measurement. Its patented method can achieve an accuracy of less than ten percent. In addition, the system allows technicians to check hundreds of bolts in a short time.
