Abstract:
A spray gun with pressure display for applying paint onto a painted object by atomizing the paint with compressed air, wherein, as a pressure indicating device capable of accurately indicating a pressure at hand where the spray gun is operated, a digitally displayed pressure indication module having a pressure sensor (25), a pressure transducer part (24), and a display part (27) unitized with each other is detachably installed on a spray gun body, and adopters (21, 22) without a pressure indication function are detachably fitted to the spray gun body according to the shape of a body grip part so that the presence or absence of the pressure indication function can be selected before use, whereby the spray gun can be used under controlled conditions by allowing a worker to detect an air pressure at hand during spraying operation since the spraying air pressure largely affects paint finish as well as dispersion of atomized paint.
Abstract:
An object of the present invention is to provide an improved electrostatic painting device wherein spray coating may be carried out by keeping a spray distance of the electrostatic painting machine within an optimum distance range which provides a good coating efficiency and to prevent the coating worker from extending unconsciously the spray distance out of the optimum distance range. The electrostatic painting device according to the present invention comprises an electrostatic spray gun 2 provided with a high voltage generation part 201 for supplying a high voltage to atomized painting material, detection means 107 for detecting load current I which varies depending on a change of the spray distance L between the electrostatic spray gun 2 and an article 4 to be coated, processing means 107 having a threshold of the load current value corresponding to the maximum distance within the optimum distance range of the spray distance and adapted to output an alarming signal when the detected load current falls below said threshold and an alarming means 108 adapted to receive said alarming signal and provide an alarming indication.
