Ein Kanal (7) erstreckt sich durch das Pumpengehäuse (1, 11) und den Lagerzapfen (2) hindurch, der, auf einer Seite des Pumpengehäuses (1, 11), ein Ende eines Filterkreislaufs, der durch den Flüssigkeitsfilter (6A, 6B) verläuft, und, auf der gegenüberliegenden Seite des Pumpengehäuses (1, 11), ein Ende des Förderkreislaufs oder der Förderstrecke mit einander verbindet.
Abstract:
A gear pump and gear pump housing are provided. The gear pump housing includes an inner wall and an outer wall. The inner wall defines an inner pumping cavity having a pumping cavity inlet and a pumping cavity outlet. The outer wall surrounds at least part of the inner wall. The outer wall being spaced apart from the outer wall defining a pressure cavity between the inner and outer walls. The pumping cavity outlet is in fluid communication with the pressure cavity. As such, the pressure cavity may be supplied with high pressure fluid that is pumped. The gear pump includes a pair of pumping gears between the pumping cavity inlet and pumping cavity outlet.

Abstract:
A progressing cavity pump adapted for pumping of compressible fluids, comprising an inner rotor (1) having a number of thread-starts (Z) together with an adapted stator or outer rotor (2) provided with one extra thread-start (Z+l), wherein a number of, in principle closed pump cavities (6) are formed which are moved, during fluid conveyance, from the inlet side (A) of the pump to the outlet side (B) of the pump, at which position they become open outlet cavities (6c) exposed to the fluid pressure in a downstream pipeline, and wherein at least one passage is disposed between the outlet side (B) and the, in principle, closed pump cavity (6b) defined closest to the outlet side (B), wherein said passage is structured for intentional fluid back-flow from the outlet side (B) in a measured and approximately constant volume.
Abstract:
Surface-active solid-phase catalyst activity may be substantially improved by creating deliberate repetitive surface-to-surface contact between portions of the active surfaces of catalyst objects. While they are immersed in reactant material such contact between portions of the active surfaces of catalyst objects can substantially activate the surfaces of many heterogeneous catalysts. Examples are given of such action employing a multitude of predetermined shapes, supported catalyst structures, etc. agitated or otherwise brought into contact to produce numerous surface collisions. One embodiment employs a gear pump mechanism with catalytically active-surfaced gear teeth to create the repetitive transient contacting action during pumping of a flow of reactant. The invention is applicable to many other forms for creating transient catalytic surface contacting action. Optionally catalytic output of such systems may be significantly further improved by employing radiant energy or vibration.

Gegenstand der Erfindung ist ein Verfahren zur Herstellung einer mit einer Diamantlage oder solchen Schicht beschichteten Verdränger-Komponente und eine solche Baukomponente (als tribologisch belastetes Bauteil). Zum Fördern oder Dosieren eines chemisch aggressiven Fluids wird vorgeschlagen, eine Grundbaukomponente (2,3) aus einem chemisch nicht ausreichend resistenten, aber mechanisch genügend stabilen ersten Werkstoff (A) werkstoff-abtragend und dabei auf ein erstes Maß (m1) genau zu fertigen. Die erst-maßgenaue Grundbaukomponente (2,3) wird hernach zumindest auf - für das Verdrängen aktiven - Flächenabschnitten mit einer zumindest 1 µm starken Schicht (10) aus synthetischem Diamant mit einem Beschichtungsverfahren beschichtet, Erhalten wird ein zweites Maß (m2) der Bauteilkomponente, passend für die Verdrängereinheit (1). Es entsteht eine chemisch beständige, reibungs-reduzierte Bauteilkomponente zum Verdrängen des chemisch aggressiven Fluids.
Abstract:
The invention relates to a high pressure cleaning device comprising a motor driving an internally toothed gearwheel pump for supply of a cleaning fluid, under high pressure, to an outlet device. Said internal tooth gear and/or an external tooth gear comprise a molybdenum containing chrome steel alloy which also contains a nitrogen component of 0.1 - 1 % and which increases the corrosion resistance and hardness of the toothed gearwheels.
Abstract:
The invention relates to a housing construction for accommodating and bearing a microsystem, e.g. a micropump (MP) for conveying a fluid. The aim of the invention is to improve the housing construction in such a way that it is no longer necessary to produce a special housing construction for each different application. To this end, several elements of a layered structure (20; 30; 31; 32; 40; 11; 12) are provided, including at least two which extend vertically in relation to a housing axis (100). One of said layered structure elements is configured as a support plate (30) with an axially oriented recess (30a) for receiving a first and second functional element (A) of the fluidic microsystem. One of the layered structure elements is configured as a connecting block (11) for mounting an inlet and an outlet (60) for carrying fluid (F) to and from the microsystem. An additional plate-shaped layered structure element (31; 20) is located between the connecting block (11) and the support plate (30) and bears an axially oriented channel segment (20a; 31k, 31k'), a peripherally oriented channel segment (41k, 41k') or a radially oriented channel segment (20r), or a combination of at least two of these channel segment types (20a, 20r) for guiding the fluid (F) through from the connections of the connecting block (11) to the microsystem in the recess (30a) in the support plate (30) and back.
