Fault analysis of high oil temperature of torque Converter of loader
The high oil temperature of loader torque converter is a common fault. When the fault occurs, the loader cannot work properly. At the same time, the high oil temperature also accelerates the oxidation and foaming of hydraulic oil, making it lose the lubrication performance of moving parts, leading to the damage of seals and affecting the normal operation of the machine. Through the example, several causes of the failure are analyzed in detail, and corresponding solutions are put forward.
Transmission assembly includes:Loader gearbox housing、Loader torque converter housing、Overrunning clutch、Torque converter movement assembly、Torque Converter Pump、Turbine group 1 and 2、Torque converter guide wheel
After the overhaul, a certain loader was used for ballast in the culvert. After less than a month of use, it was found that the oil temperature of the torque converter had reached 120℃ after the continuous working of the transmission system for half an hour, and it was obvious that the bucket was weak. The variable speed oil pressure gauge shows 1.1mpa, indicating that the variable speed oil pressure is normal. In order to find out the cause of the failure accurately, the factors that may lead to the oil temperature rise of torque converter are investigated one by one from the heat dissipation machine.
