Product details

The "Open TBM Oil Cylinder" typically refers to the oil cylinders used in open-type Tunnel Boring Machines (TBMs). These oil cylinders play a crucial role in the operation of TBMs, providing thrust, support, and other functions. Below are some specific details about the Open TBM Oil Cylinder:

1. Types:

• Support Shoe Oil Cylinder: Primarily used to provide thrust for the cutterhead during tunneling, helping the TBM stably support itself against the tunnel wall during excavation.

• Thrust Oil Cylinder: Provides the main thrust for the TBM to advance forward.

• Torque Oil Cylinder: Used for steering the TBM and transmitting torque to the cutterhead.

• Shield Oil Cylinder: Stabilizes the cutterhead and prevents the surrounding rock from converging and causing the machine to jam.

2. Structure:The oil cylinder mainly consists of components such as the cylinder barrel, piston, piston rod, and end cover. Seals are installed between the parts to prevent hydraulic oil leakage, and buffering devices are configured at the ends.

3. Working Principle:It is based on the conversion between hydraulic energy and mechanical energy. Hydraulic oil enters the cylinder barrel through oil pipes, pushing the piston to move and driving the components connected to the piston rod to move, thereby outputting mechanical energy.

4. Performance Characteristics:

• High-strength materials and special heat treatment and welding processes ensure that the oil cylinder has a high fatigue durability life under high pressure and heavy loads.

• Some oil cylinders are specifically designed to meet the high vibration conditions during TBM construction.

• Reliable sealing configurations suitable for TBM operating conditions are designed for different types of oil cylinders.

• The design has a wide temperature range and can provide customized oil cylinders for higher or lower temperatures.

5. Applications:In tunnel excavation projects, open-type TBM oil cylinders are indispensable key components. They ensure that the TBM can efficiently and safely complete excavation tasks by providing stable thrust and support.

In summary, the Open TBM Oil Cylinder is an important part of open-type Tunnel Boring Machines. Its types, structure, working principle, performance characteristics, and applications are directly related to the excavation efficiency and safety of TBMs.
