Where does built-in hydraulic contamination come from?
By Josh Cosford, Contributing Editor When I sat in my first fluid power class 18 years ago, I remember learning about built-in contamination and how the reservoir was the biggest offender. The welds and their slag were the biggest problems, the teacher stated, but a close second was the debris from pipe threading machines. Looking […]
Fail-safe locking device can hold four million pounds
Fluid power engineers are familiar with hydraulic load-holding or counterbalance valves that prevent sudden load drops and control descent speed. Such valves ensure smooth, stable operation and provide a safety mechanism in mobile and industrial machinery. The downside is they can fail due to wear, incorrect positioning, or failures in the hydraulic system. Pennsylvania-based York […]
