In the field of tunneling, the Tunnel Boring Machine (TBM) is increasingly used, and its efficient and accurate tunneling capability cannot be achieved without the support of a key component – the hydraulic cylinder. As the core power component of TBM, the performance of hydraulic cylinder directly determines the driving efficiency and safety.

Classification by Function

Tunnel boring machine hydraulic cylinder according to different functions, mainly divided into propulsion cylinder, support cylinder, guide cylinder and so on. The propulsion cylinder is responsible for providing thrust during driving, the support cylinder ensures the stability of the equipment during driving, and the guide cylinder is used to adjust the direction of driving. Each type of hydraulic cylinder is carefully designed and rigorously tested to ensure reliable operation in complex geological conditions.

According to the Structural Characteristics of Classification

From the structural characteristics, the hydraulic cylinder of tunnel boring machine can be divided into single acting cylinder and double acting cylinder. The single-acting cylinder is usually used in the scene with large unidirectional thrust demand, and the structure is relatively simple; The double acting cylinder can provide thrust in both directions, which is suitable for the condition that the driving direction needs to be adjusted frequently. In addition, according to the different materials and sealing methods, the hydraulic cylinder can be further subdivided into a variety of models to meet the needs of different customers.
