1. The hydraulic cylinder and surrounding environment should be clean. The fuel tank must be sealed to prevent contamination. Pipelines and fuel tanks should be cleaned to prevent falling off iron oxide scale and other debris.
2. The base of the Yantai hydraulic cylinder must have sufficient rigidity, otherwise the cylinder tube will bow upwards when pressurizing, causing the piston rod to bend.
3. The central axis of the movable cylinder with a fixed foot base should be concentric with the center line of the load force to avoid causing lateral force, which is likely to cause seal wear and piston damage. When installing the hydraulic cylinder of the moving object, keep the cylinder and the moving object in parallel with the direction of movement on the guide rail surface, and the parallelism is generally not more than 0.05mm/m.
4. Install the sealing gland screw of the Yantai hydraulic cylinder body, and its tightening degree is to ensure that the piston moves flexibly in the full stroke, without blockage and uneven weight. Too tight a screw will increase resistance and accelerate wear; too loose will cause oil leakage.
5. For hydraulic cylinders with exhaust valve or exhaust rosette, the exhaust valve or exhaust rose must be installed at the highest point in order to remove air.
6. The axial ends of the Yantai hydraulic cylinder cannot be fixed, and one end must be kept floating to prevent the influence of thermal expansion. Due to factors such as hydraulic pressure and thermal expansion in the cylinder, there is axial expansion and contraction. If both ends of the cylinder are fixed, all parts of the cylinder will be deformed.
7. When disassembling the hydraulic cylinder, take care to prevent damage to the thread on the top of the piston rod, the thread of the cylinder port and the surface of the piston rod. It is strictly forbidden to hammer the surface of the cylinder and the piston. If the surface of the cylinder bore and the piston is damaged, sandpaper is not allowed, and it must be carefully polished with fine oil. 1. The hydraulic cylinder and the surrounding environment should be clean. The fuel tank must be sealed to prevent contamination. Pipelines and fuel tanks should be cleaned to prevent falling off iron oxide scale and other debris. Use lint-free cloth or special paper for cleaning. Cannot try twine and adhesives as sealing materials. The hydraulic oil is designed according to the design requirements, pay attention to the changes of oil temperature and oil pressure. When there is no load, unscrew the exhaust bolt to exhaust.
