The cylinder is a commonly used component in mechanical equipment, whose role is to store the liquid and complete a certain work by pushing the piston under the pressure of the liquid. The oil cylinder is widely used in various engineering machinery, agricultural machinery, shipbuilding, aviation fighter aircraft and spacecraft. The following will introduce the structure, type and selection of the cylinder in detail.
First, the structure of the cylinder
The structure of the cylinder is mainly composed of cylinder, piston, seal, cylinder head and connecting rod. The cylinder wall and the bottom are packed with a sealing structure and a piston guide mechanism, and the piston is sealed with a sealing ring and a piston rod, and the cylinder head and the cylinder wall are also required to ensure sufficient sealing. In addition, the oil port of the hydraulic cylinder can be set in different positions according to the needs of the user, some of the oil port is slightly stagnant, and some of the operation feels more sensitive.
Second, the type of cylinder
1. Single use oil cylinder
A single acting hydraulic cylinder can only produce thrust in one direction. Its structure is simple and the price is low. This type of hydraulic cylinder usually has two structures, that is, single rod and double rod.
2. Double acting oil cylinder
Double acting hydraulic cylinder can produce thrust in both directions, and it is a relatively common hydraulic component.
3. Multi-linkage or compound cylinder
Multi-link or compound hydraulic cylinder is also a more common hydraulic component, its output force can be achieved through the cooperation of multiple links, and its larger output force can even reach hundreds of tons.
