The tension caused by internal oil leakage after wear and tear of gear oil pump results in its low volumetric efficiency. Because all of the funeral changes to heat energy, it will cause the oil pump to overheat. If the combined plane is compacted, the floating axle sleeve will be worn out due to a few activities during the task, which will result in the promotion of tillage tools being slow or unable to be promoted. Such floating axle sleeve must be replaced or repaired. Gear pump is a pair of involute gears with the same parameters and layout rolling meshing each other, which can lift the low-pressure oil in the tank to the tension components of high-pressure oil that can work. Therefore, it is necessary to convert the rigid energy of the advocate machine into the power of hydraulic energy. In a word, gear oil pump should be maintained and maintained, and proper operation should be paid attention to when using, so as to avoid running wear and tear and damage of equipment.
