Abstract

The automatic lubrication system of the mining dump truck is provided with pressure by a hydraulic gear pump. The pressure sensor provides real-time working pressure feedback for the lubrication system, serving as a basis for the electromagnetic pressure relief valve control system. The lubrication condition of the articulated bearings in the mining dump truck has a significant impact on the truck's utilization rate. Proper lubrication is directly related to extending equipment lifespan and reducing equipment maintenance costs. By researching and analyzing the principles of the automatic lubrication control system for mining dump trucks, and considering the characteristics, types, and maintenance difficulties of lubrication system failures, we propose a PLC modification to the original control system. This modification aims to enhance system operational stability and reduce maintenance costs.
