Shot and dust cleaning: After daily shutdown, the residual shot and dust accumulation in the separator, dust collector and chamber must be thoroughly removed to avoid blockage affecting the ejection efficiency.
Conveying system inspection: Check whether there are foreign objects stuck on the rollers and chains, and clean up the debris in time to prevent scratches on the steel plate surface or damage to the transmission parts.
Add specified type of lubricant (such as lithium-based grease) to the bearings, chains, reducers and other parts of the shot blaster according to the instructions. It is strictly forbidden to mix different brands of grease.
It is recommended to use a "timing, quantitative, and fixed-point" lubrication record table to avoid leakage or excessive lubrication.
Shot blaster blades: Check the wear condition daily. If the wear on one side exceeds 2mm or cracks appear, replace it immediately to avoid blade breakage and damage to the chamber body.
Guard plates and seals: Observe whether the rubber sealing curtain of the chamber body is damaged and whether the guard plate bolts are loose to prevent the leakage of projectiles and cause safety hazards.
Cycle Maintenance items Operation standards
Weekly 1. Backflush cleaning of dust removal system filter cartridge Compressed air pressure ≥ 0.5MPa, single backflush ≤ 10 seconds
2. Screen inspection of shot circulation system Screen damage rate ＞5% needs to be replaced to prevent large particles from clogging the blasting head
Monthly 1. Tighten the wiring terminals of the electrical system Use a torque wrench to reinforce according to the standard torque value to avoid virtual connection
2. Adjust the tension of the hoist belt Deflection value is controlled at 10-15mm, too loose and easy to slip
Quarterly 1. Dynamic balance detection of shot blasting machine Vibration value ＞4.5mm/s requires shutdown and calibration to reduce bearing loss
2. Clean the dust accumulation of dust removal fan impeller Use special tools to remove the agglomerated dust and restore the fan air volume
Uneven shot blasting: Check whether the opening of the shot flow valve is consistent and whether the screen is blocked to cause impurities in the shot material
Dust removal effect is reduced: check whether the filter cartridge is damaged and whether the pulse valve is ineffective, and replace consumables in time.
Before maintenance, be sure to cut off the power supply and hang a "no start" warning sign to avoid accidents caused by misoperation.
When replacing the blades of the shot blasting machine, they need to be replaced in groups to ensure the dynamic balance accuracy. Single-piece replacement can easily cause the equipment to vibrate beyond the standard.
