Presumably, everyone should be familiar with the basic composition of hydraulic cylinders. In fact, their main components are nothing more than cylinder barrels, pistons, cylinder heads, piston rods, and sealing devices. In practical operations, the output force of the hydraulic cylinder is directly proportional to the effective area of the piston and the pressure difference on both sides. The cylinder barrel plays a crucial role in the entire device.
Presumably, everyone should be familiar with the basic composition of hydraulic cylinders. In fact, their main components are nothing more than cylinder barrels, pistons, cylinder heads, piston rods, and sealing devices. In practical operations, the output force of the hydraulic cylinder is directly proportional to the effective area of the piston and the pressure difference on both sides. The cylinder barrel plays a crucial role in the entire device.
So, from a usage perspective, when making hydraulic cylinder barrels, we must ensure their comprehensive performance such as pressure resistance, wear resistance, and fatigue strength. Because it plays a crucial role in the lifespan of the entire device. Normally, we require that the cylinder barrel produced should be able to withstand a pressure of up to 20 MPa, and it should be a continuous pressure.
If it is stirred, the requirement for its ability to withstand pressure will be higher. If analyzed from the perspective of hydraulic relationship, the linear pressure f1 generated by the hydraulic cylinder body is equal to the product of the system fluid pressure f2 and the effective area A of the piston.
Obviously, for hydraulic cylinders, the cylinder barrel components play a crucial role in determining the magnitude of this linear pressure. Therefore, when making cylinder barrels, clear technical requirements are given for the steel pipes used. Firstly, during the stress relieving annealing treatment of steel pipes, if the heating temperature cannot reach the material's phase transition temperature, the basic structure of the metal material will not change.
In addition, during the processing, we not only need to improve the plasticity and toughness of the steel pipes used in the cylinder, but also need to improve their bending strength, twisting resistance, and fatigue strength according to the actual situation. To ensure that the hydraulic cylinder produced can meet the working requirements.
