Frequently asked questions
What happens when a hydraulic seal fails?
A failed hydraulic seal causes fluid leakage, leading to reduced system pressure, loss of machine force and speed, increased oil consumption, environmental contamination, and potential damage to pumps and valves operating without adequate fluid supply.
How can I identify worn seals in my drilling equipment?
Signs of seal wear include visible fluid leaks around cylinders and connections, reduced hydraulic system pressure, slower machine movements, increased oil consumption, and contaminated hydraulic fluid appearing milky or discolored.
