【Professional Knowledge】Types of Hydraulic Cylinders

The multi-stage telescopic cylinder, also known as the telescopic hydraulic cylinder, is a composite cylinder device composed of two or more piston hydraulic cylinders. Its working principle is: when the hydraulic oil enters from the rodless chamber, the cylinder with the largest piston effective area begins to extend, and when it reaches the end, the cylinder with the second largest piston effective area begins to extend, and so on. In this way, by extending from large to small, a longer working stroke can be obtained. The smaller the effective area of ​​the extended cylinder, the faster the extension speed, and the corresponding hydraulic thrust changes from large to small. When retracting, it is generally retracted from small to large, and the axial length is short, the space occupied is small, and the structure is compact. It is often used in hydraulic systems with small installation space but large stroke. The multi-stage telescopic cylinder can adjust its cascade number and diameter according to needs to achieve the required stroke and output force. It is widely used in industrial production, automobile manufacturing, aerospace and other fields.

Wantong Hydraulic Technology: Single-acting/Double-acting Hydraulic Cylinders

Single-acting hydraulic cylinders rely on liquid pressure to achieve movement in only one direction, while their reverse movement depends on external forces, such as deadweight or springs. In the two chambers of this type of cylinder, only one chamber is connected to the hydraulic system, and the other chamber is connected to the atmosphere.
