2.1: Preventive Maintenance
The
GEMS system requires periodic inspection and regular maintenance for optimum performance and the
least possible down time. Follow the corresponding table as a guide to perform routine maintenance at
suggested specified intervals. These intervals are recommendations and largely depend on the material
being sprayed.
Daily / Each Shift:
Ensure mixed material is properly flushed with solvent at the end of the shift. Verify there is no mixed
material or air pockets in the fluid lines.
Identify and correct air and fluid leaks on the system including fluid hoses, flow meter, dispense
pump, and mix manifold locations.
Ensure spray guns are functioning properly and air is not leaking from the air valve.
Check Alarm History and review errors with operator. Verify that any issues have been corrected.
Ensure material supplies are filled and pressures are correct.
Monthly
Examine B pump oil reservoir tubes for presence of hardener.
Check all air and fluid lines for kinks, cuts, or wear.
Perform Resin + Hardener calibration to ensure flow meter and dispense pump are working properly.
Inspect static mixer assembly at mix manifold outlet. If static mix elements become clogged,
disassemble and replace the mix elements as needed. Balancing alarms or increasing outlet pressure
may indicate clogging.
• Ensure all CCVs are opening and closing properly. Remove valves and clean or repair if needed.
• Disassemble and inspect flow meter for excessive wear or buildup of material. Clean as needed. Verify
smooth dispense pump movement after reassembly.
• Clean and reassemble the mix manifold and check valves.
Check fluid hoses for buildup of material. Replace if needed. With plural component coatings, buildup
of material is common around the hose fittings. This is a potential source for contamination of the
finished product.
As Needed
Rebuild mix manifold – replace O-Rings and parts within the injector assembly.
Rebuild B pump – required if “B” material begins to leak from the oil reservoirs, or if the A Only
Calibration is correct, but the A+B Calibration is inaccurate.
Rebuild Color Change Valves – monitor valves for air leaks or slow response time when triggering.
Improper pump operation may be attributed to failing color change valves.
Set limits of B Pump or replace Pot Wiper and/or Bracket assembly if damaged.
NOTE:
Fluid properties vary greatly. If a material clogs any component more frequently than expected, adjust the
maintenance schedule accordingly.
