摘要： An oil-lubricated slide vane rotary vacuum pump with a slide vane unit, and with an oil separating and reconditioning device, wherein oil and gas are separated by separating devices, possibly complemented by oil coolers and/or oil pumps. One or more monitoring and/or servicing devices are provided, and the oil separating and reconditioning device is installed in an oil separating and reconditioning housing. Side walls extend transversely to a plane of rotation of a slide vane rotor, and define a longitudinal extent of the oil separating and reconditioning housing. The one or more monitoring and/or servicing devices are arranged only in one or more cover parts which are attached to one or both end walls of the oil separating and reconditioning housing. The oil separating and reconditioning housing is formed with the side walls, the bottom wall and the top wall without being configured for a monitoring and/or servicing device.

摘要： A vacuum pump, e.g. a rotary vane vacuum pump, generates a vacuum, in a suction device, with an air intake device and an air exhaust device, as well as a motor for driving the vacuum pump. The air exhaust device is provided with a discharge valve. The exhaust air is downstream of the discharge valve divided into two partial flows that are respectively associated with a pipe section.

摘要： A method for cleaning a filter in a filter device, which includes a filter housing and the filter located in the filter housing, the filter device having a removable filtered-material collection chamber, into which filtered material arising during the cleaning of the filter is transferred. A filter device has a filter housing and a filter located in the filter housing, and a removable filtered-material collection chamber, into which filtered material arising during the cleaning of the filter is transferred. A separable space is provided upstream of the filtered-material collection chamber in the transfer direction of the filtered material, in which space the cleaned-off filtered material is treated in order to reduce remaining reactivity.

摘要： An oil-lubricated rotary vane vacuum pump includes a rotary vane unit, having a rotary vane chamber and a rotary vane rotor, and an oil separator device having an air/oil separating unit that has a filter element with a plug-in ring that can be plug-connected on a housing side. The plug-in ring is designed for radial sealing and axial displaceability in a housing receptacle. The filter element has a moulding for bayonet mounting, which faces the end associated with the outer wall. A mounting wall of the housing, extending at a distance from the outer wall of the housing, is designed to interact with the moulding of the filter element and to form the bayonet mounting. A separate cover closes a mounting opening associated with the filter element in the outer wall of the housing. The cover form-fittingly interacts with the filter element to secure the filter element against rotation.

摘要： The invention relates to an impeller (1), in particular for a side channel machine, comprising blades (5) arranged distributed in the circumferential direction and formed in each case by a blade wall (6), which blades form open blade chambers (4) in a plan view onto the impeller (1), wherein a blade wall (6) in the plan view starts at a first radius dimension (r1) related to the geometrical impeller rotation axis (x), which first radius dimension (r1) corresponds to half or more than half of a second radius dimension (r2), which second radius dimension (r2) defines a circumferential rim edge (9) of the impeller (1), and wherein the radius dimension (r1) defines a radially inner boundary wall (7) of the blade chamber (4), wherein furthermore a blade wall (6) comprises an exposed upper terminating edge, which runs correspondingly radially on the inside into the inner boundary wall (7) and ends radially on the outside in plan view, wherein an imaginary connecting line (V) can be drawn between a run-in point of the terminating edge (12) into the inner boundary wall (7) and a radially outer end of the terminating edge (12) and the terminating edge runs normal to the connecting line (V) with a different offset dimension, wherein a greatest offset dimension results. For the advantageous development, in particular with regard to improved efficiency, it is proposed that the greatest offset dimension corresponds to 0.1 times or more the difference between the second (r2) and the first radius dimension (r1).
