INZOC Online Oil Monitoring System Helps China Railway Group's Shield Machine to Realize Digital Operation Management



 The shield machine system is divided into hydraulic and gear systems. The working environment of the shield system is very harsh, with a large amount of groundwater and dust invasion. As the movement of the shield parts, the hydraulic system plays a key role in the support of the system, and the gears are highly loaded. The work brings about abnormal wear of the cutter head drive system, and the oil contains rich information of the equipment, which can reflect the health of the equipment in real time.

02/Customer Pain Point


The core system of the shield machine is divided into a hydraulic system and a gear cutter head operating system. The hydraulic system plays a vital role in the support of the shield working surface, the rotary conveying motor, and the hydraulic filter system. The normal operation of the hydraulic system concerns the entire underground shield. The operational efficiency and effectiveness of the structural system, once the equipment fails, will have very serious consequences for the advancement of the project and production safety. The implementation of health management for such large-scale equipment is an urgent problem to be solved.
