1. Spray booth
Every day, clean up the accumulated powder in the spray booth (even if the color is not changed), to prevent the powder from accumulating for a long time and solidify on the spray chamber.
Every week, check whether the air hole of the “airflow pulse floor cleaning device” at the bottom of the spray booth is blocked. Clean it up in time after plugging and the cleaning air pressure is controlled between 2-4 bar.
2. Large cyclone separator
Every day, clean up the accumulated powder in the cyclone (even if the color is not changed), otherwise the powder will solidify on the inner wall of the cyclone due to high-speed rotation, resulting in a decrease in cyclone separation efficiency; Check the mesh screen and clean up the accumulated powder on the screen. If the mesh surface is damaged, replace it in time; clean up the powder recovery barrel to prevent the powder from agglomerating and affect the powder recycling; check whether the mesh screen can be lifted smoothly, whether the seal is intact to prevent low recovery efficiency due to air leakage.
Every week, clean up the powder in the powder recovery pump, to prevent accumulation of agglomerates and affect recycling.
Every six months, check the wear condition of the powder pump and the powder tube, replace it if necessary.
The powder recovery pressure is set at 2-4 bar. If the powder recovery efficiency is too low, adjust the atmospheric pressure appropriately, and vice versa.
Every week, open the side panel of the reciprocator to check the tightness of the timing belt, tighten it in time and clean up the powder adhering to the rail.
Every month, open the top hat and side panels of the reciprocators to check the wear condition of the pulleys and bearings, replace them if necessary.
4. Powder box
Every week, clean up the powder in the powder box.
Every three months, check the fluidization situation of the fluidized plate and the sealing of the fluidized plate, replace it if necessary.
