Walterscheid presents its range of hydraulic cylinders with integrated damping systems.
- Based on a hydraulic cylinder with integrated gas accumulator and damping mechanism
- Nitrogen gas accumulator is integrated in the piston rod
- Damping mechanism controls the flow of hydraulic oil to reduce pressure peaks
- Gas accumulator absorbs extra pressure created by mechanical impacts on hydraulic element
- Hydraulic fluid taken in due to extra load is returned to the system evenly, and there is no risk of a rebound stroke
- Rebound strokes are damped via a system which controls the energy release phase by adjusting the return flow rate
- Block valve protects fluids inside the cylinder
- Valve for refilling gas is easily accessible at the end of the piston rod
- Screw plug protects the valve against dirt and acts as an additional seal
- Accumulator piston is made of aluminum and features low-friction seals designed to withstand high temperatures
- Damping valve is located inside the cylinder piston
- Movement required for positioning cylinder is the same as with standard processes, preventing it from being positioned too close to the end of a stroke, which would prevent any adjustment of the cylinder length and thus any absorption of excessive loads
- Helps enhance machine productivity by improving road-holding properties, allowing ground speed to be adapted in case of difficult conditions
- Operator comfort is improved as shocks and counter-shocks are reduced
- Fewer pressure peaks reduces wear
- Provides reliable accumulator operation even under extremely challenging conditions
- Seals with a low friction factor and high thermal resistance allow internal accumulator to operate across a range from -20-80 C (-4-176 F)
