Reasonable structural design Consider the oil return groove, oil return hole, vent hole and guide plate for the sealing part of the mechanical equipment, so that the lubricating oil can smoothly flow back to the oil pool. The pressure difference between the inside and the outside of the sealing part is uniform, and the hydraulic oil and lubricating oil should be filtered before being added to the fuel tank, and the lubrication system, the cooling system, the filtration system of the hydraulic system should be strengthened, and the damaged filtering device should be replaced in time.

The impurity mixed in the oil is often small in diameter, close to the thickness of the oil film, and easily enters between the oil seal edge and the shaft surface, thereby functioning as an abrasive, which deteriorates the sealing condition and increases the wear of the seal and the shaft, resulting in wear. Oil leakage, therefore, mechanical equipment should be repaired and cleaned regularly.

During maintenance, 1 should clean the surrounding environment; 2 disassembled parts should be cleaned and the mechanical equipment should be cleaned. Commonly used methods of cleaning parts are: mechanical cleaning, immersion in solution, spray washing (jet flushing), solvent steaming Flow cleaning, ultrasonic vibration cleaning and cleaning fluid circulation cleaning. 3 During maintenance, check the straightness of the rotating shaft, dynamic balance, radial runout of the bearing, axial turbulence, roundness, concentricity and surface roughness of the shaft at the seal. If it does not meet the requirements, it must be repaired to be qualified or replaced. The new component, because the fault analysis shows that the shape tolerance of the shaft does not meet the requirements, the swing occurs during the rotation, and the vibration easily causes oil leakage. For example, when the bending shaft with the oil seal rotates, there is a part of the oil around the edge of the oil seal lip. It can't rotate with the shaft, causing a gap between this part of the oil and the shaft, and it can't get the oil sealing effect, and the oil overflows. 4 Prevent the use of scrapped sealing elements.
