The massive and heavy load work of the dynamic compactor makes it often have failures of one kind or another. Regular maintenance and servicing can avoid some failures. The dynamic compactor rental manufacturer suggests that the gear oil of the reducers at various places should be replaced regularly. The following analysis:
1： (Main winch) inspection and oil change of lifting reducer
The first oil change shall be carried out every 500 hours after 150 hours. The position for checking the oil volume of the main winch reducer is the plug of a screw plug on the side. When changing the oil, first place the steel wire rope on the drum to expose the oil filling hole and oil drain hole, then remove the oil drain plug directly below the reducer drum, and then remove the plug plug directly above the reducer drum for air exhaust, so that the oil can be drained normally. Then install the oil drain plug, and inject about 6-7L CL-585W/90 heavy load vehicle gear oil from the oil filler, and then install the oil filler plug.
2： The oil volume inspection and the first oil change of the traveling reducer shall be conducted 150 hours later and every 1500 hours thereafter. Filling method: rotate the reducer to make the oil plug horizontal and lower. Then remove the lower oil plug, and then remove the oil drain plug at the horizontal position to drain the oil. Then rotate the decelerator so that the oil plug is level and above. Then pour about 8 to 9 liters of CL-585W/90 heavy-duty vehicle gear oil from the oil plug directly above. When the gear oil leaks from the horizontal oil plug, install the horizontal oil plug. Add half a liter of gear oil
3： Inspection and oil change of luffing reducer
Change the oil every 1500 hours. First remove the vent plug and filler plug, and then remove the drain plug to drain the oil. Then install the oil drain plug, inject about 3L CL-585W/90 heavy load vehicle gear oil from the oil filler, and install the oil filler plug and vent plug. When the storage life of the reducer exceeds 12 months, special inspection and anti rust treatment must be carried out.
4： Oil quantity inspection and oil change of slewing reducer
The oil shall be changed for 150 hours for the first time and every 1500 hours thereafter. Remove the oil filler plug on the reducer first, and then remove the oil drain plug at the oil drain port to drain the oil. After the oil is drained, first install the oil drain plug, add 6 liters of No. 18 hyperbolic gear oil from the oil filler, and fill the oil to the depth of 50-35 mm from the oil filler oil level port, and then install the oil filler plug.
The working life of the reducer can be greatly improved through proper maintenance and repair measures. Visual inspection shall be carried out every day, especially the sealing of the reducer. Regularly check the reducer for abnormal noise. Check the oil level of the reducer regularly.
Selection and replacement of hydraulic oil: The hydraulic oil shall be selected according to the ambient temperature. If the ambient temperature is low, the hydraulic oil with low viscosity shall be used. On the contrary, the hydraulic oil with high viscosity shall be used. Each time the oil is changed, the oil tank and filter shall be carefully cleaned, and the oil shall be injected through the filler screen.
