When using high-pressure airless paint sprayers, you might encounter some common issues. Here are detailed solutions
Nozzle Clogging
Clean the Nozzle: Use a cleaning needle or cleaner to clean the nozzle. If necessary, remove the nozzle and soak it in solvent. This step is especially important when using a China airless paint sprayer.
Preventive Measures: Filter the paint before use, choose the appropriate filter density, and ensure the paint is free of impurities. This is effective for Graco airless sprayer parts and other brands of equipment.
Uneven Spraying
Check Pressure Settings: Ensure the pressure is set within the appropriate range. Increase the pressure if streaking occurs; decrease it if there is overspray. This is a basic operation for any high-pressure airless paint sprayer, including those with China made Graco pump parts.
Stir the Paint: Use a mechanical stirrer to thoroughly mix the paint to ensure uniformity.
Spraying Technique: Maintain a consistent spraying speed and distance (usually 12-18 inches) to ensure even coverage. This applies to all brands and models of spraying equipment.
Equipment Leaks
Check Seals: Regularly check and replace seals to ensure they are not aging or damaged. Graco pump repair parts offer various options for this purpose.
Installation Check: Ensure all connecting parts are securely installed and not loose. Tighten with a wrench but avoid over-tightening to prevent thread damage.
Unstable Pressure
Check the High-Pressure Pump: Regularly maintain the high-pressure pump, clean internal components, and ensure there are no blockages. Both Graco pump repair parts and China made Graco pump parts can be used for this purpose.
Regulator Maintenance: Check if the pressure regulator is working properly; adjust or replace it if necessary.
Power Check: Ensure the power supply is stable with no voltage fluctuations. Using a voltage stabilizer can improve power stability.
