? Oil temperature is too high A. What are the reasons: oil hydraulic system to maintain proper Tai'an regular schools excavator, generally in the range of 35 ~ 60 ℃ appropriate school Taian excavator phone, causing the oil temperature is too high The main reasons are: (1) the system inefficient schools excavator, element small capacity excavator Tai'an best schools, the flow rate is too high; (2) Fuel tank capacity, or poor heat dissipation; viscosity (3) oil is too large; ( 4) Oil qualitative change bad, the viscosity of the oil increases, the resistance increases; poor (5) cooling performance. Tensioning device damage determination: ① tension drain or leakage "butter" within the fuel tank - the board has failed to adjust the track or just a good tune to use and relaxation. ② guide bar off; ③ buffer spring break; ④ ram and bracket Sun gray; ⑤ guide wheel axle or other damage Tai'an sleeve formal schools excavator _ Kerry and excavators school (online consultation) _ Heavy excavator schools and by the Taian Jia Machinery Limited.
