Turbine Group 1 And 2 for XCMG DOOSAN/XCMG 500K Turbine Group/DOOSAN 503 Turbine Group/Lonking 855 SDLG 953 Turbine Group Several factors leading to high oil temperature of loader torque converter 2.1 Insufficient system oil intake pressure According to the heat dissipation principle of the torque converter transmission system, the variable speed pump absorbs working oil from the transmission oil pan through the pressure regulating valve, all the way into the torque converter, after cooling by the radiator back to the oil pan; The other way into the transmission. If the system oil intake pressure is insufficient, the working oil pressure into the torque converter is too small, so that the oil intake is insufficient, the oil into the cooler is too little, so that the oil in the system can not be fully cooled, the oil temperature rises quickly and leads to the transmission temperature is too high. The main reasons for the insufficient oil intake pressure of the system are as follows: (…
