    摘要： A rotary piston pump, in particular a claw pump, includes a housing which, when placed in a customary manner, has a housing inlet in a housing upper side. In order to further improve a rotary piston pump in a beneficial way, the housing inlet is connected to a gas channel that is integrated in the housing and extends transversely to a rotational axis of the piston, which gas channel creates a flow connection to a gas outlet of a filter part arranged in a filter receptacle. In the installed state, the filter part is accessible from a side perpendicular to the housing upper side, for maintenance purposes, for example.

    摘要： The invention relates to a rotary slide assembly and to a method for monitoring the wear of one or more slides in a rotary slide assembly, comprising a rotary slide rotor and one or more slide receiving areas for the slide(s) in the rotary slide rotor. The wear state of the one or more slides is detected during the operation or during a standstill of the rotary slide assembly. For this purpose, the slide(s) or one or more corresponding slide receiving areas in interaction with the one or more slides are used to generate or request an electric or electronic signal.

    摘要： A method for operating a metal printing device has an enclosure in which the metal printing is carried out, the enclosure having an inlet and an outlet, and a fan also being provided, with which the atmosphere in the enclosure can be regenerated, a device also being provided in order to be able to extract particles in particular after a printing process is complete. In a first method step, process gas is extracted from the enclosure and conducted through a regeneration device in order to clean the atmosphere in the enclosure. In a second method step after the printing process is complete, excess particles are removed from the enclosure. A suction fan having a suction line connection is provided, wherein the mode can be switched over using a switchover device connected upstream of the suction fan.

    摘要： A method for cleaning a filter in a filter device having a filter housing and the filter located therein, the filter device including a filtered material collecting chamber to receive filtered material which accumulates during the cleaning of the filter. The filtered material collecting chamber is filled with a fire prevention agent before it first receives filtered material. The filtered material collecting chamber is filled with a solid material over part of the volume of the filtered material collecting chamber. In the course of a removal of the filtered material collecting chamber from the filter device, a targeted exchange of a chamber atmosphere for the surrounding atmosphere is carried out, and in connection with an inflow of atmospheric air, a mixing movement of the filtered material collecting chamber for mixing the filtered material with the solid material is carried out.
