Hydro Turbine Bearings

onsite hydropower maintenance services

Hydro turbines are machines that convert water power into mechanical energy. They consist of two main parts: the rotor (which spins) and the stator (which generates electricity). The turbine bearings protect the machine from general wear and tear over time. In this article, we will discuss everything you need to know about hydro turbine bearings. 

Cutting Edge Onsite Machining is a leading provider of hydro turbine maintenance needs. Our company provides the most experienced and technically-advanced machinists in the industry to help projects stay on track with unparalleled quality for machining services. Contact us today at 936-262-6006

How Do Hydro Turbines Work

A hydro turbine uses the kinetic energy of water to generate mechanical energy. When the water gets moved to the right place, the energy is taken by the hydro turbine and converted into usable electrical energy.

The hydro turbine is constantly moving. However, that means the risk of damage to the turbine is increased. Thus, it requires regular maintenance and repair. 

Hydro turbine bearings can be damaged by coming into contact with foreign objects like debris and rocks. The more contact the bearings have with these objects, the more wear and tear they will receive. Also, due to weather conditions, like harsh storms or wind that can cause an increase in water flow. This then results in more pressure on the bearings and stress. 

How Do Hydro Turbine Bearings Work

Bearings are designed to reduce friction between rotating and stationary components. As mentioned above, the hydro turbine has a constant motion. Therefore, there is always some amount of friction between the bearing and the shaft. To prevent excessive heat build-up, the bearings must allow for some movement. If the bearings were perfectly still, the friction would be too high, causing excessive heat build-up. 

In addition, the bearings also play a role in maintaining the integrity of the machinery. For example, if the bearings fail, the entire machine may become unstable and fall apart.

What Are Hydro Turbine Bearings Made Of?

There are many different types of hydro turbine bearings. These include ball bearings, roller bearings, ceramic bushings, needle bearings, plain bearings, and thrust bearings. Each type of bearing has its own advantages and disadvantages.

Ball bearings are generally made of steel and are suitable for use in medium-sized applications. Ball bearings are usually not recommended for larger applications because their performance decreases as the size increases. 

Roller bearings are ideal for large applications. They are made of hardened steel and are able to withstand heavy loads. Roller bearings are often found in industrial equipment such as conveyors and cranes. 

Ceramic bushings are similar to roller bearings but are made out of ceramics. Ceramics are much stronger than steel and are therefore better suited for larger applications. 

Needle bearings are small and thin. They are typically used in smaller applications where space is limited. 

Plain bearings are very common in hydro turbines. Plain bearings are made of cast iron and are suitable for medium-sized applications. 

Thrust bearings are used when there is a lot of force being applied to the bearing. Thrust bearings are made of bronze and are best suited for large applications.

Common Issues With Hydro Turbine Bearings

As mentioned earlier, hydro turbines are constantly moving. This causes the bearings to experience a great deal of wear and tear. Over time, this can lead to failure. Below, we discuss some common issues with hydro turbine bearings.

  • Friction: Friction occurs whenever two surfaces come into contact. In the case of hydro turbine bearings, friction occurs at every point where the bearing contacts the shaft. 
  • Heat Build-Up: Heat build-up happens when friction is too high. High temperatures can result in material fatigue and premature failure. 
  • Stress: Stress is caused by external forces. External forces can be from wind, rain, snow, ice, etc. All of these factors put stress on the hydro turbine bearings. 
  • Lubrication: The oil or grease that lubricates the bearings needs to be changed periodically. When the oil or grease becomes old, it will break down and cause damage to the bearings. 

Why Should You Keep Your Hydro Turbine Maintained

Hydro turbine maintenance is extremely critical for operational and safety reasons. Hydro turbines have many parts that need to work together in order for them to function properly. If one part fails, the whole system could stop working. Also, hydro turbines are expensive pieces of equipment. It’s important to make sure they run smoothly so that you don’t waste money on repairs.

If you notice any problems with your hydro turbine, you shouldn’t delay in contacting someone to perform an inspection on your hydro turbine. Hydro turbines are complex machines that require professional attention. If you wait until something goes wrong, you may find yourself spending more money fixing the issue than if you had performed the regular maintenance checks.
