As a key component of power transmission, hydraulic cylinders are used in practice, due to the large differences in the working environment, so the structure and function requirements of the hydraulic cylinders are also different in different applications. However, no matter what kind of working occasion, strength and rigidity are basic requirements for hydraulic cylinders.
In other words, in order to satisfy the normal operating requirements, the hydraulic cylinder must satisfy these two basic requirements. Moreover, because the cylinder structure bears relatively high tension and pressure, it is necessary to ensure the reliability and safety of the cylinder. Then, in the process of planning, it is necessary to check the strength and rigidity of its components.
Regarding the specific verification work, there are actually three aspects, namely, the verification of the diameter and stability of the piston rod of the hydraulic cylinder, and the verification of the cylinder wall thickness.
Regarding the check of the diameter of the piston rod, the main reason is that during the normal working period of the hydraulic cylinder, the piston rod will be subjected to a larger load force. And it needs to reciprocate back and forth in the cylinder according to the work requirements, then the piston rod will be subjected to thrust, tension and torque. Since these loads are large and unevenly distributed, it is necessary to ensure that the piston rod has high strength and excellent rigidity.
The main reason for checking the cylinder wall thickness is that the entire hydraulic system will be exposed to greater pressure. Therefore, in order to prevent the cylinder body from deforming or cracking, it is necessary to ensure that the cylinder body has a satisfactory thickness to withstand the pressure of the hydraulic system.
In fact, it is to check the stability of the hydraulic cylinder. The key to this part is actually to check the stability of the piston rod. As an important part of hydraulic cylinder equipment, the stability of the piston rod plays a very important role in the function of the entire equipment. Usually the slenderness ratio of the piston rod is checked. It is necessary to ensure that the slenderness ratio is less than a certain critical value to ensure the required stability.
