Precautions For Installation Of Large Oil Cylinder

1. The large oil tank and its surrounding environment should be kept clean. The fuel tank is sealed to prevent contamination. Pipes and fuel tanks should be cleaned to avoid falling off iron sheets or other garbage. Need velvet or special paper to keep clean. Hemp and adhesives should not be used as sealing materials. The hydraulic oil is designed according to the design, pay attention to the change of oil temperature and hydraulic pressure. When no-load, loosen the exhaust bolt to exhaust.
2. The connecting rod of the piping should not be loose.
3. The base of the large oil cylinder has sufficient rigidity. Otherwise, the cylinder barrel will bow and the piston rod will bend when pressurized.
4. Before installing the large oil cylinder to the system, please compare the parameters on the nameplate of the large oil cylinder with the parameters at the time of ordering.
5. The axis of the moving cylinder with fixed feet is concentric with the line of the load force. In order not to generate lateral force, the working principle of the hydraulic system is that the lateral force is likely to cause wear of the seal and damage to the piston. The large oil cylinder of the moving object is installed so that the cylinder is parallel to the moving direction of the moving object on the track surface, and the parallelism is usually below 0.05mm/m.
6. Install the sealing and pressing screw of the cylinder body, in order to ensure the flexible movement of the piston in the whole stroke, there is no uneven weight with the cylinder body, and the fastening condition is good. Overtightening the screws will increase resistance and accelerate wear. Overtightening can cause oil leakage.
7. For large oil cylinders with exhaust valves or exhaust valves, install the exhaust valve or exhaust valve at the highest position.
8. The axial ends of the cylinder cannot be fixed, and one end is floating to prevent the influence of thermal expansion. Large customized hydraulic system cylinder expands and contracts axially due to hydraulic and thermal expansion. When both ends of the cylinder are fixed, each part of the cylinder deforms.
9. The gap between the guide cover and the piston rod should meet the requirements.
10. Pay attention to the parallelism and straightness of the cylinder and the guide rail, and the deviation is within 0.1mm/full length. When the total length of the busbar on the large oil cylinder is different, repair the contact surface between the bottom surface of the large oil cylinder base and the machine tool. When the side busbar difference should meet the requirements, loosen the large oil cylinder and the fixing screw, pull out the positioning lock, and correct the accuracy of the side busbar.
11. When disassembling the cylinder, please do not damage the screw at the front end of the piston rod, the screw at the end of the cylinder, or the surface of the piston rod. Do not hit the surface of the cylinder and piston with a hammer. Such as cylinder bore and piston surface loss. Sandpaper is not allowed. Be well researched with fine oil. The cylinder and surrounding environment remain clean. The fuel tank is sealed to prevent contamination. Pipes and fuel tanks should be cleaned to avoid falling off iron sheets or other garbage. Need velvet or special paper to keep clean. Hemp and adhesives should not be used as sealing materials. The hydraulic oil is designed according to the design, pay attention to the change of oil temperature and hydraulic pressure. When no-load, loosen the exhaust bolt to exhaust.
