When using our hydraulic cylinders, it’s important to note that the recommended working oil viscosity ranges between 29 to 74 mm²/s, with ISO VG46 anti-wear hydraulic oil being ideal. The optimal operating temperature falls within the range of -20°C to 80°C. If the ambient or operational temperatures are low, especially in larger cylinders, consider switching to oils with lower viscosities.
The filtration system in your hydraulic setup must maintain a precision level of at least 80 microns. Keeping the oil free from contaminants is crucial; regular checks of the oil’s condition, along with necessary fine filtration, will help preserve its quality. Additionally, replacing the working oil when needed ensures continued performance.
During installation, align the piston rod joint with the cylinder head and ensure that the entire piston rod remains straight while moving back and forth. Avoid rigid interference or unnecessary damage by carefully managing these components.
After installing the hydraulic cylinder on the main machinery, run a test to inspect for leaks around the oil outlet pipe and guide sleeve. Also, lubricate the bearings on the ear and intermediate hinge shafts.
In the event of oil leakage or other issues, apply hydraulic pressure to shift the piston to one end of the cylinder before disassembly. Try to avoid rough handling like sudden drops or excessive knocking.
Before starting disassembly, first release the hydraulic pressure by loosening the relief valve until the pressure reads zero. Turn off the power and disconnect the hydraulic equipment. Once the oil lines are loosened, block the ports with oil plugs.
Never use the piston rod as a ground for electrical purposes to prevent potential shocks.
