The Tunnel boring machine is a large-scale engineering machine used in large infrastructure projects. Such as highway tunnels, railway tunnels, and subsea tunnels. The environment in the tunnelling work is very harsh. It is faced with large dust and various wet geological layers, such as soft soil bottoms, rock formations, etc. The environment is very unfavourable for the equipment. After years of research and development, Yates has accumulated rich experience in oil monitoring. An intelligent online oil monitoring system. It can check the lubricating oil wear status of the shield machine in real-time. It can help customers understand the health of the equipment oil in real-time. And protect the equipment from damage.
1. Working principle of Working principle of tunnel excavator
The basic working principle of the 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 temporary support for the excavated section of the tunnel that has no line. 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 under a shield cover.
2. Customer Difficulties
The shield machine relies on two major systems for support in the tunnelling work. One is the hydraulic system. which is responsible for the activities of the equipment when it travels. One is the gearbox cutter head system. which is responsible for the operation of the cutter head excavation and withstands excellent 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.
Online oil monitoring system A set of oil online remote intelligent detection and diagnosis systems. It is based on the IoT platform. Modular design is realized internally.
4. scope of test:
