Troubleshoot the cause of the problem that the hydraulic cylinder cannot operate：
Generally speaking, the problem that the hydraulic cylinder can't move often occurs on the newly installed hydraulic cylinder. Generally, it is necessary to check from external factors, such as whether the mechanism dragged by the hydraulic cylinder has too much resistance, whether it is stuck, or resists others. Components, etc.; whether the hydraulic cylinder oil inlet pressure value is within the specified value range.
After these factors are eliminated, check the interior of the hydraulic cylinder. For example, the oil may not enter the hydraulic cylinder; the sliding parts of the cylinder itself are too tight; or the hydraulic cylinder is improperly designed and manufactured.
To further troubleshoot the problem, check the hydraulic cylinder's oil pipes, oil passages, especially hose joints, to see if they are blocked; as well as the valve seat of the overflow valve, once there is dirt, it will also cause the cone valve and the valve seat to be sealed If it is not good, it will cause leakage, and the dirt needs to be cleaned up in time. When the hydraulic cylinder lateral load is too large, the force is not strong, or the cylinder is seized by pulling the cylinder, the same consequences will occur. Therefore, when installing the hydraulic cylinder, the axis position of the hydraulic cylinder must be consistent with the direction of movement; when the hydraulic cylinder is placed horizontally, the weight of the piston and the piston rod will be deflected, causing the guide sleeve and the piston to generate eccentric loads.
