As the project a wide range of machinery, specifications, machine weight, large parts, the general approach to spray paint. Spray tool air spray gun, airless spray gun, air-assisted spray gun and portable electrostatic spray gun. Low air spray gun efficiency (about 30%) with the engine manufacturer of construction machinery, high pressure airless paint spray gun waste, both common feature is more serious environmental pollution, it has been and is being air-assisted electrostatic spray gun and the hand-held replaced. On the hood, such as sheet metal cover portable electrostatic spray gun is used. Engineering machinery coating equipment generally use more advanced water rotary spray booth. Water spray chamber by chamber body rotation, electric doors, mist filter dust collector, air supply and exhaust device component unit; lighting equipment installed on both sides of the body chamber, more than 500 Lux illuminance can be grouped control; combustible interior design The main air supply system is to form a laminar flow of gas; gas concentration detection and alarm devices; mist filtration device consists of washing the plate, hydraulic spinning device, consisting of ground water tank and exhaust system, mist removal efficiency> 98% Parts Construction Machinery engine compartment into the air supply filtered, heated evenly from the ceiling to the gas feed to the interior construction machinery engine brand, indoor wind speed even when no workpiece vertical wind speed of up to 0.35 ~ 0.4 m · s - 1 exhaust system with mist blower gas chamber containing the body through hydraulic spinning tube filter, discharged from between the sink and wash board.
