Common Faults and Treatment of Double Drum Coal Mining Machine in Comprehensive Mining Face
Combined with the mining face of a mine,the applied MG300/700-WD coal mining machine often occurs operation failure problems,mainly related to the hydraulic system height adjustment failure,the cut-off part of the oil temperature is too high,the coal mining machine traction force is insufficient,the coal mining machine rocker arm lifting and lowering failure and the coal mining machine frequency inverter failure,etc.,so that the quality of the face of the return mining operation is affected.For this reason,firstly,the case of back-mining project is elaborated,then the structure and principle of MG300/700 coal mining machine is analysed,and finally,targeted troubleshooting is carried out based on the common problems,in order to expect that the failure rate of the coal mining machine can be effectively controlled,and the operation quality of the coal mining machine can be improved.
