摘要:
An electrostatic fluid delivery system is configured to deliver fluid, such as a disinfectant fluid, onto a surface by electrically charging the fluid and forming the fluid into a mist, fog, plume, or spray that can be directed onto a surface, such as a surface to be cleaned. The system atomizes the fluid using a high-pressure fluid stream and passes the fluid through an electrode of a nozzle assembly to charge droplets of the atomized fluid.

An electrostatic fluid delivery system (105) is configured to deliver fluid, such as a disinfectant fluid, onto a surface by electrically charging the fluid and forming the fluid into a mist, fog, plume, or spray that can be directed onto a surface, such as a surface to be cleaned. The system (105) atomizes the fluid using a high-pressure air stream and passes the fluid through an electrode inside a nozzle assembly (205) to charge, such as negatively charge, droplets of the atomized fluid. The system uses a unique nozzle design that is configured to optimally atomize the fluid into various sized droplets.

A liquid dispensing module (10) and nozzle or die tip (28) for discharging at least one liquid filament (74). The nozzle (28) includes a strand guide (42) for guiding a substrate past the nozzle (28) and a frustoconical protrusion (56) disposed on a surface of the nozzle adjacent the notch (42). A liquid discharge passage (48) extends along an axis (48a) through the frustoconical protrusion (56) and forms an acute angle with a machine direction corresponding to movement of the strand (44) past the nozzle (28). Four air discharge passages (60,62,64,66) are positioned at the base of the frustoconical protrusion (56). Each of the air discharge passages (60,62,64,66) is angled in a compound manner generally toward the liquid discharge passage (48) and offset from the axis (48a) of the liquid discharge passage to create the controlled pattern (74) of liquid material on the strand (44).

An electrostatic painting apparatus (1) includes: a paint gun (4) that has a bell cup (4a) serving as an atomization portion that atomizes a paint, and an air nozzle (7) serving as ana air discharge portion that discharges shaping air for controlling a diffusion pattern of the atomized paint; a high-voltage generator (5) that applies a high voltage to the paint gun (4); and a controller (6) that controls the high voltage to be applied from the high-voltage generator (5), wherein the high-voltage generator (5) generates a high positive voltage.
摘要:
The invention relates to a coating device and to an associated coating method for coating components with a coating medium, in particular for painting motor vehicle body components and/or motor vehicle accessories with a paint. The coating device comprises at least one applicator unit (8, 9) for expelling the coating medium from at least one coating medium nozzle. Furthermore a drop generator (TE; TE') can be provided in order to impose a vibration and/or an instability on the coating medium in order to generate coating agent drops (70) and/or to break down the coating medium into drops (70). The applicator unit (8, 9) is preferably provided in order to expel at least one coherent coating medium jet (70') which breaks down into drops (70).
摘要:
The invention relates to an electrostatic spraying arrangement for the serial coating of workpieces, wherein the high-voltage sensors (7) and actuators (6) of the sprayer (11) are supplied by an isolating transformer (T1-T3) in the sprayer (11) and/or in a robot arm (10) with a high voltage insulation path. Control and sensor signals for the actuators (6) and sensors (7) are transmitted potential-free, for example, optically or by radio.
