on hydraulic oil (1) The cleanliness of hydraulic oil is too poor, the pollution particles are large, and the sticky sand and welding slag in various hydraulic control valves and pipelines are also one of the reasons for pollution. Because the gap between the shaft diameter of the gear shaft and the inner hole of the sealing ring is very small, the larger solid particles in the oil enter between them, causing the inner hole of the sealing ring to be worn, scratched or rotated with the shaft, causing the pressure oil of the secondary seal to enter the low pressure area ( skeleton rubber seal), resulting in the breakdown of the rubber seal, at this time should be filtered or replaced with new anti-wear hydraulic oil. (2) After the viscosity of the hydraulic oil decreases and deteriorates, the oil becomes thinner. Under the high pressure of the gear pump, the leakage through the secondary sealing gap increases. Due to the lack of time to return the oil, the pressure in the low-pressure area increases, thereby breaking down the rubber seal. pieces. It is recommended to test the oil regularly and choose anti-wear hydraulic oil. (3) When the main engine works under heavy load for a long time and the oil level of the fuel tank is low, the oil temperature can rise to 100 ℃, resulting in the thinning of the oil and the aging of the lip of the skeleton rubber seal, thus causing oil leakage; it should be checked regularly The height of the oil tank liquid level to avoid the oil temperature being too high.
