Case Studies
Pitted, Worn Wicket Gate Cylinder Successfully Upgraded with Chesterton® Solutions
Challenge
Background
A hydropower facility needed to upgrade its cylinders which actuate a wicket gate. The original seals had been stacked leather seals which were later converted to a more traditional V-Ring stack. Over the years, the box bores had become heavily pitted and worn. This had led to premature failure of the seals and subsequent leakage.
Hydropower wicket gate.
Solution
Product
Chesterton® ARC 10 was used to coat the box bores and to fill in the pitted and worn surfaces. These were subsequently honed to size to provide an even sealing surface with adequate finish. A Chesterton® R22KN seal with 9K AER Backup Ring was used to provide a reliable long term sealing solution.
Chesterton® R22KN and R9 Rings were used to replace old V-Rings.
Results
Increase Reliability
The wicket gate cylinders were successfully repaired, returning their surfaces to appropriate finishes. Chesterton’s sealing solution provided a more durable and long lasting result leveraging its best-in-class AWC800 polyurethane.
ARC 10 was used to repair the worn cylinders.
