1. Check whether the fixing bolts on all blast
turbines and motors are loose, and if they are loose, tighten them immediately.
2. Check the wear conditions of the wear
parts in the blast turbine and the guard plate in the shot blasting chamber,
and replace the worn parts in time.
3. Check the blades, they must be replaced
when they are half worn.
4. Check whether the pointer position of
the control cage is correct.
5. Whether the inspection door of the shot
blasting machine is tightly closed.
6. Whether there is air leakage in the dust
removal pipeline, and whether the filter bag in the dust collector is dusty or
damaged.
7. Whether there are deposits and other
debris on the spiral shell and filter screen of the separator, and clear them
in time.
8. Check whether the flow curtain of the
separator is uniform and a full curtain is formed.
9. Whether the electronically controlled
pill supply gate valve is closed.
10. Check whether the status of each limit
switch and proximity switch is normal.
11. Check whether the working status of
each signal indicator on the console is normal.
12. Check whether the current of the shot
blasting motor is within the rated range.
13. Clean the dust on the electrical
control box.
14. Check the wear of the pill inlet pipe
gasket, the rubber guard plate of the working door and the top seal to avoid
the loss of steel shot.
15. Remove the debris on the bottom plate
grid to ensure the recovery of steel shots.
16. Check whether the total amount of steel
shot in the shot silo is sufficient, and if it is insufficient, add it.
1. Check the abrasive distributor, if it
wears more than 3mm, replace it.
2. Check the control cage, and replace it
if the opening is larger than 6mm.
3. Check whether the guard plate of the
blast turbine is severely worn and misplaced.
4. Check the tension of the V-belt of the blast
turbine, it should be able to press about 10mm inward, otherwise it should be
adjusted.
5. Check the wear of the partitions and
slides, and replace them if necessary.
6. Check whether there are qualified steel
shots in the fine powder tube and the bulk tube that can be recycled.
7. Check whether the belt tension, bolts
and joints of the hoist are suitable, whether it is off-track and abraded.
8. Check whether there are foreign objects
and wear in the screw.
9. Check the grid of the bottom plate and
repair any loopholes in time.
10. Check the casing joints to avoid
leakage of air and dust.
11. Check the dust on the filter cartridge
of the dust collector, and use the pulse blowback mechanism in time.
12. Lubricate the bearing seats of the blast
turbines once.
13. Drain the air compressor, gas storage
tank and oil-water separator once.
1. Check and adjust the gate valve to make
it open and close to meet the current value of the shot blasting motor from 25A
to 30A.
2. Adjust the tightness of the drive chain
and provide lubrication.
3. Check the tightness of the belt of the
bucket elevator and adjust it; check the hopper bolts and tighten them.
4. Check the lubricating oil of the
reducer. If it is lower than the specified oil level, add corresponding grease.
5. Check the contact status of each AC
contactor and knife switch, and perform soot blowing and cleaning.
6. Check whether the wires and cables of
the power and control parts are loose and should be tightened.
7. Test each motor separately, listen to
whether the sound is normal, and see the no-load current. Each motor should be
no less than 5 minutes.
8. Check the wear and fixation of the fan
and air duct.
9. Add 2# calcium-based grease once a month
to the bearing seats of both ends of the hoist, separator and screw conveyor.
10. Change the oil of the air compressor
once a month.
1. Check the condition of bearings and
electric control box, and add grease.
2. Check the wear condition of the
wear-resistant guard plate of the shot blasting machine.
3. Replace the spindle bearing of the blast
turbine and the bearing of the shot blasting motor with new high-speed grease.
4. Check the tightness of the fixing bolts
and flange connections of all motors, reducers, fans, and screw conveyors.
1. Check the lubrication of all bearings
(including motor bearings) and add new grease.
2. Replace or weld repair the main chamber
body guard plate.
3. Check the reliability of the contact
between the PLC and the inverter.
4. Check whether the ammeter is accurate.
5. Check the filter cartridge of the dust
collector. If it is damaged, replace it. If there is too much dust, use an air
gun to clean it.
6. Perform necessary dredging and repair of
air ducts.
