In the production, pay attention to check the o-ring seal between the drive shaft frame and the main frame, the seal ring between the oil collector and the oil slinger, the wear of the o-ring seal ring between the oil slinger and the drive shaft. Because these parts will be deformed by wear after long-term use, the elasticity required for effective sealing is lost, and the sealing device fails, which may cause oil leakage of the equipment.
During production, check whether there is any dirt in the main oil drain hose or pipe. Check if there is any dirt in the long hole of the drive shaft frame under the drive shaft. The accumulation of dirt will hinder the flow of oil, especially the low oil temperature. At this time, the oil cannot be quickly discharged from the inside of the equipment, causing the cone crusher to leak oil.
Lubricating oil enters the lower part of the main shaft from the inlet pipe and is rubbed by the lubricating friction disc. If the working pressure of the lubrication system is improper, the oil will be ejected from the shaft gap, causing the lubricating oil to leak downward along the outer circumference of the sealing cylinder.
If the gap between the inner wall of the base oil sump and the weight body slinger plate is too small, the lubricating oil between them will easily form an oil seal under the action of tension during the working process of the cone crusher. Under the pressure of the air pressure, the oil seal will continuously overflow from the dust seal along the inner wall of the main frame.
