High Speed Turbines

Carbon Brush - High Speed TurbinesCarbon Brush - High Speed Turbines

Carbon brushes used on high speed turbine ring applications are the most critical applications in the world. Helwig Carbon has been supplying carbon brushes for these applications for over 85 years. Our H702 and H704 low friction graphite grades have been used extensively on Allis Chalmers, ABB, GE, and Westinghouse units around the world.

Trouble Shooting Tips

Due to the extremely high peripheral speeds it is difficult to maintain good contact with the ring.

· Rings should be round within .001” with less than 6 mils vibration.
· Spring pressure should be checked periodically to insure it is the recommended 2.5 psi for 3600 RPM turbines.
· Free movement of the brushes up and down in the brush holder should also be checked.

This application is susceptible to selective action and an imbalance in current flow. This can lead to a build up of deposits on the inside of the brushholders which can impede the movement of the brush. In extreme cases the brush will be held up in the holder and lose contact with the ring. Regular maintenance checks can help identify and prevent these problems before they become serious.

DIY Carbon brush

I know more than a few of us that have ‘cheap’ electric tools. I bought my grinder at HB more than a few years back and have been quite happy with it. No, its not a Dewalt or Milwaukee, but I figure 5 years of hard use, I more than got my money out of the thing.

All the grinding and cutting that I have been doing lately finally took its toll on that tool. The brushes wore out and of course that means the grinder became a paperweight. Digging around, I found brushes from the HB site, but at $4 for the brushes and over $20 in shipping, I figured I would try something else first.

I bought these carbon rods from Budget casting supply a few years back
