1. Equipment inspection (1) Check the wear of the inner liner, pill wheel, directional sleeve, blade, and impeller of each shot blaster. If there is excessive wear, it should be replaced. (2) The body of the inspection room and the guard plates in the shot blasting room should be replaced immediately if they are severely worn, punctured, broken, etc. that hinder normal use. (3) Check the protective wear-resistant sleeves of the three rollers in the shot blasting room and the protective sleeves at the end of the rollers. Replace them if they are severely worn or broken. (4) Check the damage of the sealed door curtain, and replace it in time if the damage is serious. (5) Check whether the lubrication parts are normal. (6) Check the wear and breakage of the pellets, and add a certain amount of pellets. (7) Check the dust discharge valve and ash hopper of the dust collector and clean it in time. (8) Check the wear and tear of the pill supply tube, repair or replace if it is damaged. (9) Check whether the cables, air pipes, and air pipes are normal.
2. Power-on adjustment (1) Manually open each mechanism according to the power-on sequence, and observe whether there is abnormal sound or abnormal state. (2) The workpiece is placed on the roller table and fed, adjust the pill cleaning device, and observe whether the pill cleaning effect is ideal. (3) Adjust the angle of the side mouthpiece to achieve the purpose of clearing the pill without collision. (4) Adjust the amount of shot, and the projection angle meets the effect of cleaning the workpiece. (5) Check all electrical appliances and reducer, the temperature is not higher than 35℃.
3. Operating procedures (1) Do a pre-shift inspection before starting up. (2) Before starting the machine, make sure that there are no maintenance personnel in the room and the personnel should be in a safe area. (3) Determine the shot blasting object and select the number of blasting heads. Start-up procedure: Dust collector→bucket elevator→screw conveyor→shot blasting conveyor roller conveyor→pellet feeder→blasting fan. Shutdown procedure: After the supply pill is closed, the rest of the shutdown sequence is opposite to the boot sequence.
4 .Maintenance (1) The machine should be repaired and maintained on time according to the actual usage. (2) Lubricate as required. (3) The pit should be dry to prevent the pellets from rusting and agglomerating. (4) Remove the waste in the separator and dust collector at any time to ensure the normal operation of the equipment. (5) Check the wear of the rubber sealing curtain and replace it in time. (6) Check the wear condition of the wear-resistant guard plate and wear-resistant sleeve in the shot blasting chamber, and replace it in time if damaged. (7) The blasting wheel, directional sleeve, blade, liner and other vulnerable parts in the shot blaster are seriously worn and should be replaced in time. (8) During maintenance, insert the manual inserts of each projectile gate to ensure that no projectiles are rolling, and then transport all projectiles to the storage bin. (9) Check whether the protective net is damaged and ensure that tools, fasteners, etc. cannot roll into the spiral. (10) Check whether the cloth spiral screen is damaged and replace it in time. (11) Check the wear of the hopper of the bucket elevator and replace it in time.
