Turn to turn to cause excavator excavator failure phenomenon: Excavator walking straight or turning place are normal, but the operation of any operating lever when walking alone, appeared to turn weakness. Unable to turn: 1 dextral fault excavator motor oil supply less than.2 LS pipeline reverse overflow valve.3 rotary motor on the bad.4 the main valve of the luffing and slewing relief pressure small, adjust the pressure relief valve main valve repair: turn. Excavator working device of excavator 1 speed check, overflow pressure, overflow pressure value is not walking is within the range of 2? Then, hydraulic excavator walk motor check whether the value of 3 normal? If not normal, the amount of oil in the cause of the malfunction is not enough. The excavator walk motor of excavator motor causes the shortage of oil supply are May be due to LS pipeline of excavator reverse caused, therefore in the exchange of LS pipeline connection, turn to excavator troubleshooting. In addition, the overflow valve rotary motor on the bad, rotary relief pressure and the main valve is too small also may lead to occurrence of mining machine turning weak fault. In the actual operation of the excavator, if LS tubing anti not only may lead to turn to excavator fault phenomenon, and may cause the excavator bucket rod is operated separately or when the arm and the bucket excavator speed is very slow.
