Insight for in-situ machinists: How a Francis turbine works 

Posted by Alan Hillier on Dec 20, 2017 8:38:00 AM

 

If you've worked on machining projects at power plants you may have heard of the Francis turbine. These are the most preferred type of turbine used in the hydro power sector. But how much do you really know about how they work?  The video above created by Learn Engineering does a great job in demonstrating the principles and workings behind this mainstay of the power generation industry.

In our previous blog post we listed a number of in-situ machining projects relating to power plant maintenance. This time we take a look at one of these in more detail, to and cover the equipment used and the results achieved.

As part of a turbine refurbishment project, Mirage equipment was specified to machine the casing split lines back to the original specification.  A Mirage MR2200 2 axis milling rail was used and mounted onto a Mirage gantry system. Let’s take a look at these in more detail.

When you consider the demands that turbine components in power plants are exposed to, it comes as no surprise that eventually many components will wear out and operate less efficiently. With steam turbine temperatures being of over 500°C, pressures of 4000psi and components rotating at speeds of over 3000rpm, the importance of a well-managed and robust maintenance programme cannot be overstated.  (Find out more about power plant maintenance strategies on our previous blog post).
