Therefore, the oil supply filter, the oil return filter, and the filter screen must be inspected and cleaned every month. Check the oil quality to keep the working pressure between 0.08-0.15MPa. Check the pump supply pressure and filter. The post-filtration pressure of the cleaner, ie the pressure difference, is maintained between 0.02 and 0.04 MPa.
The service life of the oil pump is generally about three months, and the oil in the hydraulic station must be filtered after three months.
Second, the cone crusher discharge port adjustment
During the crushing process, the moving cone liner and the fixed cone liner are continuously worn, so that the discharge port is gradually increased. In order to ensure a certain product strength, the size of the discharge port must be continuously adjusted. The adjustment of the discharge port is realized by the zigzag thread lifting and lowering lining plate between the adjusting ring and the support sleeve.
Adjustment method: first open the lock cylinder pressure relief valve, make the lock cylinder depressurize, use the hydraulic push cylinder to push the adjustment ring forward or backward, so that the fixed cone rises or falls, and the discharge port becomes larger or smaller. Adjustment of discharge port, a wire-based method can lead block. Measure the size of the discharge port. The size of the discharge port must be measured 4-6 points. After the discharge port is adjusted, the adjustment ring must be locked with the lock cylinder. Otherwise, the boot is not allowed.
Third, the maintenance of the cone crusher
The overhaul, repair, and minor repair and maintenance cycle of the cone crusher shall be determined according to the actual conditions of the equipment.
General maintenance (small repair) once a month, disintegration inspection
Check bowl watts (W copper plate) of the contact patch where
Check the wear of the taper sleeve and the straight sleeve
Check whether the dustproof water, dustproof waterway is clear, and the dustproof ring is worn.
Check hydraulic station, oil pump, oil pressure, oil quality
The period of the repair or repair period is about 6 months and the maximum is no more than one year.
The mid-repair includes all minor repairs
Check the contact point of the bowl tile
Check the wear of the taper sleeve and the straight sleeve and check the gap
Check the bevel gear meshing clearance
Check the wear of the horizontal shaft copper sleeve, that is, the clearance, the horizontal shaft axial clearance ¢1750, 0.8-0.9mm, ¢2200, 1.1-1.2mm, and the copper sleeve clearance shaft diameter 2/1000
Repair or replace worn parts of dust-proof devices, dredge waterways
Hydraulic station oil change, cleaning oil supply, oil return pipeline, cleaning fuel tank, filter, whether it is minor repair or medium repair, the repair of the inspection site is well recorded and the next inspection data comparison, summed up the wear law and use Time and provide a reliable basis for preparing spare parts in the future.
