Preventative maintenance is critical to the effectiveness of any equipment, no matter its quality. Effective preventative maintenance, however, requires sticking to a schedule. Without a plan in place that's designed to identify equipment problems before they can happen, you risk putting yourself in a situation that could impact your business and the performance of your equipment, which will more than likely impact your bottom line.
Spray professionals are always on the lookout for equipment that optimizes mixing performance to produce the smoothest surface for foam and coatings. In many cases, mechanical purge spray guns are the go-to to meet these requirements. Thanks to multiple impingement fluid ports, both components are mixed thoroughly to ensure spray quality is top-notch. Material that's atomized through a round or flat tip delivers a smoother finish than that of an air purge gun. Mechanical purge guns also require less air than air purge varieties. On the other hand, drawbacks of mechanical purge systems include added gun adjustments. Round tips are also more susceptible to being plugged quick than an air purge round mix chamber.
We've discussed before the benefits of an effective preventative maintenance schedule and why the success of your spraying activities depend on it. But now it's time to get more specific and look at particular pieces of equipment that can, from time to time, malfunction. It's up to you to have a plan in place that mitigates the impact of these issues before they become more significant and more costly issues.
Impingement spray guns are versatile pieces of equipment that can heat chemical components to produce both polyurea and polyurethane before mixing. This heating process reduces the viscosity of your spray material to improve mix, flow, and leveling, which boosts the performance of your spray gun to produce a gorgeous final product. These sprayers offer up to 95% efficacy and are most effective in many applications, including roof coatings, pipe and tank coatings, truck bed liners, waterproofing and roof and wall insulation.
Common Impingement Spray Gun Issues (and how to Solve Them)
Due to high pressure and temperature envelopes, impingement spray guns are known to suffer more frequent malfunctions than other types of spray guns. Fortunately, many of the issues with impingement spray guns are predictable and easy to diagnose. The majority of the issues with these spray guns are found in the valves, nozzles, as well as the mixing chamber. Some of the issues with impingement spray guns include:
A Preventative Maintenance Schedule That Works
(NOTE: Compatible solvents include N Methyl Pyrrolidone (NMP), Dynasolve CU-6, Dzolv, or equivalent to soften the cured material. )
Weekly to Monthly Maintenance
1. Clean the mixing chamber and side seal cartridges meticulously at the end of every working week. Major repairs may be done at the end of the month.
2. Every seven days, disassemble and clean check valves to eliminate any potential clogging issues.
Never Underestimate the Value of Preventative Maintenance
By having a plan in place that keeps your mechanical purge spray gun operating at peak efficiency produces an automatic competitive advantage compared to those who don't take the process of establishing a maintenance schedule seriously.
