telescopic hydraulic cylinder manufacture

The telescopic hydraulic cylinder is a hydraulic cylinder with a multi-stage sleeve-shaped piston rod that can obtain a long working stroke. The telescopic hydraulic cylinder is also called a multi-stage hydraulic cylinder.

The telescopic hydraulic cylinder is made up of two or more piston hydraulic cylinders. The piston rod of the former piston cylinder is the cylinder of the latter piston cylinder.

When the pressure oil enters from the rodless cavity, the cylinder with the largest effective area of ​​the piston begins to extend, and when it reaches the end, the cylinder with the second effective area of ​​the piston begins to extend. The sequence of the telescopic hydraulic extension is from large to small, and a long working stroke can be obtained. The smaller the effective area of ​​the extension cylinder, the faster the extension speed.

Therefore, the extension speed becomes slower and faster, and the corresponding hydraulic thrust changes from large to small; this kind of change law of thrust and speed is just suitable for the requirements of various automatic loading and unloading machinery for thrust and speed. The order of retraction is generally from small to large, the axial length when retracted is short, the space is small, and the structure is compact. It is often used in hydraulic systems of construction machinery and other mobile machinery, such as cranes and dump trucks.
