How can I repair the pressure in the loader gearbox?
(three) the gear box oil level of the oil level is too low when the gearbox oil level is too low, the oil cycle to work up transmission oil in the residence time of oil bottom and natural cooling time is short and the cooling effect is poor, resulting in transmission of fever, will also cause the hydraulic pump suction air, resulting in the decrease of pressure in the system. This kind of failure, strain gauge pressure instability and large swing, the engine speed changes, pressure gauge readings without big changes, indicating that driving hydraulic pump has suction phenomenon or inlet pipe leakage phenomenon. Should always check the oil level and add sufficient hydraulic transmission oil, if found leakage, timely maintenance. The oil level is too high. The oil level is too high transmission high speed rotating element around too much oil, the friction resistance increases, the oil temperature rise and converted into heat energy to participate in the work of the oil circulation, slow heat can not be distributed in a timely manner, and the backlog gradually with the extension of working hours, the temperature increased. (four) continuous high load loader such as long time high load operation, the heat generated in the cooling speed is fast, the working oil temperature will overrun, the temperature reaches a certain level will have a great damage to the moving parts, so it is prohibited for a long time overload operation when the ambient temperature is high, more attention should be paid to. To sum up, in order to avoid the transmission oil temperature is too high, users should strengthen management, according to the provisions of the use and maintenance, to avoid oil shortage, water shortage and long time overload operation and so on.
