Methods for the use and maintenance of large hydraulic cylinders

Certainly! Here's the rewritten content in English: --- Over time, we’ve learned that maintaining optimal conditions for hydraulic systems is crucial. For our large hydraulic cylinders, the recommended working oil viscosity ranges between 29 to 74 mm²/s, with ISO VG46 anti-wear hydraulic oil being ideal. Operating temperatures should ideally fall within the range of -20°C to 80°C. If the ambient temperature or operational conditions are low, it’s advisable to use lower viscosity oils, especially in larger cylinders. The filtration system must maintain a precision level of at least 80 microns. Keeping the oil free from contamination is essential. Regular checks of the oil’s condition are vital, along with performing detailed filtration and replacing the working oil when necessary. During assembly, it’s critical to ensure that the piston rod joint aligns properly with the cylinder head, ears, or intermediate hinge shaft. This alignment ensures smooth movement of the piston rod without causing rigid interference or damage. After installing the cylinder on the main machinery, always conduct an operational test to verify there are no leaks at the oil outlet pipe or guide sleeve. Lubricate the bearings of the ears and the intermediate hinge shafts as well. In case of oil leaks or other issues, apply hydraulic pressure to shift the piston to one end before disassembling. Avoid using forceful blows or sudden drops during this process to prevent damage. Before beginning disassembly, first release the hydraulic pressure by loosening the relief valve until the circuit pressure reads zero. Turn off the power supply and stop all hydraulic operations. After loosening the oil lines, block the ports with an oil plug to prevent leaks. It’s important to remember that the piston rod should never be used as a ground connection, as it could lead to electrical shock.
