Description

The invention relates to an adapter plate for connecting a spinning-pump device and a 5 line for conveying a spinning fluid for synthetic fibers, according to the preamble of claim 1, and to an associated spinning-pump system in which the adapter plate is used. High-precision spinning-pump devices are usually used for the production of synthetic fibers and filaments, such as spandex fibers, for example, said spinning-pump devices being 10 configured on an adapter plate for connecting the spinning-pump device, on the one hand, and for connecting conveying lines. External gear wheel pumps which are described in DE 10 2016 013 684 Al, for example, and are constructed according to the principle of a planetary gear pump are used in particular for the spinning-pump devices. 15 The primary driven gear wheel of the planetary gear pump is connected to a driving source which by meshing drives planetary gear wheels disposed on the external circumference of said driving source. The spinning fluid from a supply line is then conveyed into an adapter plate in the 20 meshing pockets formed by the external gear wheels and the primary driven gear wheel, the adapter plate having fittings by means of which the conveying lines are able to be coupled to the respective spinning nozzles. The number of external gear wheels determines the number of lines that can be fed. In 25 this way, eight lines can thus be fed in the case of eight planetary gear wheels, for example. In this instance, the adapter plate has to be provided with a corresponding number of fittings. Planetary gear pumps of this type can also be disposed in series behind one another. It is currently possible that adapter plates with up to forty fittings can be provided. 30 There are, however, limits in technical as well as spatial terms to the above.
