Embodiment Construction

[0030] In the following, with reference to the accompanying drawings in figure 1 with figure 2 An example embodiment of a powder delivery device according to the invention and a powder coating installation 100 with such a powder delivery device 1 are shown schematically in .

[0031] Although it is of course also conceivable to implement the powder delivery device 1 as a powder sparse flow pump, in the exemplary embodiment depicted in the figure, the powder delivery device 1 is designed as a powder dense flow pump, which The coating plant 100 is used to feed coating powder from a powder reservoir 101 to a powder spray gun or powder spray device 102 arranged downstream of the powder dense flow pump 1 . Instead of the powder spray gun 102 , other devices for spraying coating powder onto the object to be coated can also be used.

[0032] as in figure 2 As shown schematically in , the schematic embodiment adopted according to the powder output device 1 of the present inventio...

Abstract

The invention relates to a powder-dispensing device (1) in the form of a dense-phase powder pump or of a powder injector for delivering coating powder from a powder reservoir (101) to a powder-spraying device (102). To make the spray coating operation easier for the customer and to be able to make it more cost-effective, without having to compromise on good coating quality and good coating efficiency, the invention proposes a control device (120) which is integrated in the powder-dispensing device (1) or is connected, in particular directly, to the powder-dispensing device (1) and which is designed to establish at least one parameter that is characteristic of a spray coating procedure carried out with the powder-coating device (102).

Description

technical field [0001] The invention relates to a powder delivery device according to the preamble of independent claim 1 . [0002] Accordingly, the invention relates in particular to a powder delivery device in the form of a powder close-flow pump or powder injector for feeding coating powder from a powder reservoir to the powder spraying device. The invention relates in particular to such a powder delivery device and a powder spraying device, which include both an injector as a powder pump and a dense phase powder pump (English: dense phase powder pump). [0003] A powder close flow pump according to the present disclosure has at least one feed chamber provided with a powder input valve and a powder output valve. The feed chamber can alternatively be connected to a vacuum source during the suction phase, or to a source of conveying compressed air during the discharge phase. By means of the vacuum of the vacuum source, the powder is sucked into the feed chamber through the...
