Product details

The "Shield Tunneling Machine Cylinder" is a vital component of shield tunneling machines. Below are some detailed contents regarding the shield tunneling machine cylinder:

The cylinders of shield tunneling machines typically refer to the hydraulic cylinders used for providing thrust, support, steering, and other functions in shield tunneling machines. These cylinders play a crucial role in the operation of shield tunneling machines.

1. Types and Functions:

• Propulsion Cylinders: They are one of the primary cylinders in shield tunneling machines, used to provide the thrust for the machine to advance. They are usually distributed around the shield tunneling machine and work together to ensure the machine moves forward stably along the predetermined route.

• Support Cylinders: They are used to support the shield tunneling machine during the tunneling process, preventing it from sinking or deviating due to soil pressure, water pressure, and other factors.

• Steering Cylinders: They play a role when adjusting the tunneling direction of the shield tunneling machine. By changing the extension length of the cylinders, slight steering of the machine can be achieved.

2. Working Principle:

The working principle of the shield tunneling machine cylinder is based on hydraulic transmission technology. When hydraulic oil is pumped into the cylinder, it generates a certain pressure, pushing the piston rod of the cylinder to extend or retract. By controlling the flow rate and pressure of the hydraulic oil, the extension and retraction speed and force of the cylinder can be precisely controlled.

3. Structure and Materials:

The shield tunneling machine cylinder usually consists of a cylinder body, piston rod, seals, and other components. The cylinder body is typically made of high-strength steel to ensure it can withstand the immense pressure during the tunneling process. The piston rod is usually made of high-quality alloy steel material to improve its wear resistance and corrosion resistance. Seals are used to prevent hydraulic oil leakage, ensuring the normal operation of the cylinder.

4. Maintenance and Servicing:

To ensure the normal operation of the shield tunneling machine cylinder, regular maintenance and servicing are required. This includes checking the sealing performance of the cylinder, cleaning the cylinder surface, replacing worn-out seals, etc. Additionally, the cleanliness and viscosity of the hydraulic oil need to be checked regularly to ensure it meets the working requirements of the cylinder.

In summary, the "Shield Tunneling Machine Cylinder" is an indispensable component of shield tunneling machines, and its performance directly affects the tunneling efficiency and safety of the machine. Therefore, in the design and use of shield tunneling machines, sufficient attention should be paid to the selection, installation, debugging, and maintenance of the cylinders.
