Hydraulic cylinder cushion adjusters
WebSince hydraulic cylinders are not guaranteed for zero oil leak-age, it may not be possible to hold a stopped position for an extended period of time. 3. Take surge pressure into consideration. Use cylinders which can withstand the surge pressures (maximum allowable pressure) generated in hydraulic systems. (Refer to specifications.) Web2 okt. 2024 · Hydraulic cylinder cushions are a cost-effective method for providing failsafe collision control of heavy moving structures. Progressive cushioning using multiple needle valves in a series cavity arrangement can make the deceleration velocity curve infinitely adjustable to meet the needs of the application.
