Application of oil online monitoring system in Tunnel boring machine

The Tunnel boring machine is a large-scale engineering machine. which is use in large infrastructure projects such as highway tunnels, railway tunnels, and subsea tunnels. The environment in the tunneling work is very harsh. It is faced with a large amount of dust and various wet geological layers, such as soft soil bottoms, rock formations, and so on. The environment is very unfavorable for the equipment. Yateks has accumulated rich experience in the field of oil monitoring after years of research and development. An intelligent online oil monitoring system. It can monitor the lubricating oil wear status of the shield machine in real-time, can help customers understand the health of the equipment oil in real-time, and protect the equipment from damage.

1.working principle

The basic working principle of Tunnel boring machine is that a cylindrical steel component moves forward along the tunnel axis while excavating the soil. The shell of the cylindrical component is the shield. It acts as a temporary support for the excavated section of the tunnel that has not been lined. Withstand the pressure of the surrounding layers, and sometimes withstand the pressure of the groundwater and keep the groundwater out. Excavation, dumping, lining and other operations are carried out under the cover of a shield.

2.Customer Difficulties

The shield machine relies on two major systems for support in the tunneling work. One is the hydraulic system, which is specifically responsible for the activities of the equipment when it travels. One is the gear box cutter head system, which is specifically responsible for the operation of the cutter head excavation and withstands great strength. The hydraulic system and gearbox system have accumulated long-term high-load work, which will cause the hydraulic system oil to deteriorate and produce a large number of pollution particles and gearbox gear fatigue wear. Once the equipment fails, it will cause damage to the equipment. Delays in the progress of the project are unacceptable.

3.solution
