The screening machine is generally reliable and easy to operate, but if it fails, it will be damaged in a short period of time if it is not processed in time. Therefore, the operation and maintenance personnel need to master its performance, and timely maintenance can ensure the long-term normal operation of the screening machine.
First, the operation of the screening machine (A) Before starting the machine, the lubricating parts such as the exciter should be inspected to ensure the proper oil level. Make sure that components such as gear bearings are well lubricated.
(2) Check if the connecting piece is loose and ensure its tightness, especially the bolt of the fixed exciter.
(3) The starting sequence of the screening machine is: if there is a dust removal device, the dust removal device should be started first and then the screening machine should be started. After the operation is normal, the feeding to the sieve surface is allowed evenly. The order of shutdown is the opposite.
(4) When the screening machine is in normal operation, pay close attention to the temperature of the bearing.
(5) Pay attention to whether the screening machine has strong noise during the operation. Whether the vibration of the screen box is stable. If the screen box has shaking, check whether the stiffness of the four supporting or hanging springs is consistent and whether there is any breakage.
(6) During the operation of the equipment, the wear condition should be checked regularly. If any parts have worn out excessively, they should be replaced in time.
Second, the maintenance and overhaul of the screening machine should be carried out by a full-time staff. Weekly inspections, monthly inspections and annual inspections should be conducted.
(1) Weekly inspection: Check whether the vibration of the vibration exciter and each part is loose, check whether the screen surface is slack and damaged, and whether the sieve hole is too large, and the problem should be dealt with in time.
(2) Monthly inspection: Check the screen frame member itself or the weld for cracks. If there is a crack, the surface should be cleaned. Drill φ5mm at the end of the crack, shovel out the groove and preheat it and repair the weld. Ensure the penetration, weld the weld after welding, and add the reinforcing plate. In order to avoid stress concentration, it is not allowed to perform gas cutting holes and welding accessories on the screen frame by itself.
(3) Annual inspection: coping with the large cleaning and maintenance of the exciter. When disassembling, it should be noted that the bearing inner ring and the bearing body are marked with the same mark, so that the inner ring and the original bearing are misplaced during assembly after cleaning, and the bearing should be seated to maintain the original clearance of the bearing. If the bearing is found to be pitting, the entire set of bearings should be replaced. When replacing the bearing, first preheat the inner ring of the original bearing, remove it from the main shaft, and then heat the inner ring of the new bearing to 80-100 °C and load it into the main shaft. When reassembling, be aware that the eccentric blocks of the exciters on both sides are to be in the same phase.
(4) Lubrication: According to different types of exciters and bearings, oil should be injected regularly according to its requirements. A large cleaning of the exciter bearings should be carried out every year to ensure good lubrication.
