Training The ABC’s of Spray Equipment

 Open the catalog to page 1

While this book examines the spray finishing operation and its equipment from many viewpoints, there is still much more to be learned to become truly proficient at spray finishing. The best way to become proficient at spray finishing is to just do it! Many Technical Colleges and Colleges of Further Education have courses involving spray finishing, a great way to improve your skills. We have our own Training School at the UK manufacturing site and regularly conduct courses there. The “art” of the professional spray finisher involves an indepth knowledge of the paints and coatings in use. The manufacturers...

sprayed material. This will normally require the absence of all loose particles, dust and scale. In the most common cases this will involve the ‘dusting down' of the surface with a compressed air gun. More stubborn contamination may need the use of a bristle or wire brush while the worst situation may need the application of acid etching or particle blasting. Dust or loose particle contamination will block the sprayed material from keying and adhering to the surface, producing peeling and a displeasing visual appearance. Likewise, any liquid or chemical contamination could also produce the same...

dirt. Use clean containers to mix the paint in and always filter the liquid while pouring it into the gun, pump or tank. Dirty paint will not only clog your spray gun, but it will also ruin your paint job. Paint is never as clean as it looks. 6. Health and Safety The spray shop is a dangerous place. Every day we work with lung clogging dusts, poisonous and carcinogenic chemicals, highly flammable liquids and high pressure fluids and gasses. In order to maintain our health it is essential that correct procedures are followed and that the correct protective clothing and equipment is used. A strong...

125 psi. 6. Where are single stage compressors used? Figure 2 - Sectioned Single stage compressor 4. How does a rotary screw compressor work? Rotary screw compressors utilise two intermeshing helical rotors in a twin bore case. Air is compressed between one convex and one concave rotor. Trapped volume of air is decreased and the pressure is increased. The application of this compressor is usually limited to a maximum pressure of 125 psi. It can be used above 125 psi, but above this pressure, two stage compressors are more efficient. 7. What is a two-stage compressor? A compressor with two or more...

which performs one or more of these functions, is considered to be air control equipment. elimination of pulsation from the compressor and to allow the air to cool before use. 3. What are the types of air control equipment? Air control equipment comes in a wide variety of types, but it basically all performs one or more of the following functions; air filtering and cleaning, air pressure regulation and measuring of pressure and air distribution through multiple outlets. Some typical devices to perform these functions are called air transformers, air regulators, air filters, air coalescers, air...

Figure 10. - Pipe Sizes 8. How often should the filter/regulator be drained of accumulated moisture and dirt? It depends largely on the level of system use, the type of filtration in the air system, and the amount of humidity in the air. For average use, once-a-day drainage is probably sufficient. For heavily used systems, or in high humidity, drainage should occur several times daily. Some units drain automatically when moisture reaches a predetermined level. 9. What steps should be taken if moisture passes through the filter/regulator? Since moisture in the spray gun atomisation air will ruin...

capable of removing water droplets but cannot remove water vapour. vapours and toxic fumes. This is true, even under ideal conditions. Anyone near a spray finishing operation should use some type of respirator, or breathing apparatus. This chapter covers various types of equipment for this use. If, due to ambient conditions or expansion of the air as it leaves the air cap, the air drops in temperature water droplets or mist can be created which will adversely affect finish quality. Therefore the vapour must be removed by a specialised air dryer. There are two main types of drier, the refrigerated...

Figure 1. - Dust Respirator These respirators are equipped with cartridges or filters that remove only solid particles from the air. In their simplest form they are a pressed formed fibre mask that covers the nose and moth and is held in place by an elasticated strap. They are effective, however, in abrasive operations such as sanding, grinding and buffing. 5. What is an organic vapour respirator and where is it used? This type of respirator, which again covers the nose and mouth is equipped with cartridges that remove organic vapours by chemical absorption. Some are designed with prefilters to...

contaminants. The compressed air is passed, at a known flow rate, through tubes containing crystals impregnated with certain chemicals. The various 'contaminants' listed in 10 react with the chemicals to produce a colour change allowing the level of contamination to be seen and measured. A different tube is used for each of the four main contaminants. NOTE: Before using any respirator, carefully read the manufacturer's Safety Precautions, Warnings and Instructions. Many respirators are not suitable for use with isocyanates, chromates and 2-component paints. transfer compressed air from the air...

Figure 4.- Pressure loss in different hoses 10. Do fluid supply systems suffer from pressure loss as well? Yes, the numbers are different (higher viscosities than air) but the effects are still seen. There are no easy ways to determine pressure loss in these hoses. 11. How are hoses maintained? Hoses will last a long time if they are properly maintained. Be careful when dragging hose across the floor. It should never be pulled around sharp objects, run over by vehicles, kinked or otherwise abused. Hose that ruptures in the middle of a job can ruin or delay the work but is also highly dangerous. The...
