The features of telescopic cylinders mainly include the following aspects:
Multi-stage sleeve piston rod design: The telescopic cylinder adopts a multi-stage sleeve piston rod design, which enables the cylinder to obtain a longer working stroke. When the cylinder is extended, it extends in order from large to small piston effective areas, thereby obtaining a very long working stroke.
Sequence of extension and speed change: When the telescopic cylinder is extended, it usually starts with the cylinder with a larger piston effective area, and then extends in order from large to small piston effective areas. Since the smaller the effective area of the extended cylinder, the faster the extension speed, the extension speed changes from slow to fast, and the hydraulic thrust changes from large to small. This change law is suitable for the thrust and speed requirements of various automatic loading and unloading machinery.
Hydraulic principle and pressure difference effect: The working principle of the telescopic cylinder is based on the hydraulic principle, and the movement of the piston is driven by the pressure difference generated by the hydraulic pump to achieve extension and retraction. In the liquid supply stage, the liquid is transported into the cylinder body, and the movement of the telescopic cylinder is generated by the movement of the piston; in the oil return stage, the liquid flows back into the hydraulic system through the gap of the sealing element.
Strong load-bearing capacity: Since the telescopic cylinder adopts a multi-stage sleeve-shaped piston rod design and works on the hydraulic principle, it has a strong load-bearing capacity and can meet the needs of various engineering machinery and other walking machinery.
Compact structure and small space occupation: The telescopic cylinder occupies less space when retracted, with a compact structure and easy installation and use. This design allows the cylinder to be shortened when it is not needed to save space
