Definitions
- the present invention relates to a rotary pump for the delivery of liquids and for the promotion of solids-containing liquids.
- the rotary lobe pump consists of a pump housing, which is provided with an inlet and an outlet.
- the pump housing has a lining.
- In the pump housing, or within the lining at least two oppositely rotating rotary pistons are arranged, which form pump chambers during their rotation. During the rotary movement, the rotary pistons are sealed against each other, against the pump housing and against the lining.
- German Patent Application DE 10 2006 041 633 A1 discloses a pump with a housing formed from two intersecting cylinder sections, inlet and outlet openings being provided on opposite sides and a rotor rotatable about its central longitudinal axis being arranged in each cylinder section.
- the larger transverse axes of the rotor are in each case at least one movement phase approximately perpendicular to each other with the runners sealingly rolling against each other and against the housing inner wall, and extending from the intersection of the large transverse axes generatrix lines run each runner in opposite directions obliquely to the respective central longitudinal axis.
- Each runner comprises two approximately club-shaped sections, which are connected at their narrower end via a constriction.
- the two runners When the large transverse axes of the two runners are perpendicular to each other engages the club-shaped portion of a runner in the constriction of the other runner and the two runners roll sealingly from each other. In each phase of the rotational movement, the two runners form a uniformly increasing suction volume in front of the inlet opening and a uniformly decreasing outlet volume in front of the outlet opening. To improve the pump performance and increase the stability is provided that the functioning as a sealing lines
- German Utility Model DE 20 2009 012 158 U1 discloses a rotary lobe pump for conveying a fluid medium containing solids.
- the pump is provided with two rotary lobes with intermeshing lobe vanes and each having a rotation axis and an outer circumference, the axes of rotation of the two lobes being spaced apart from each other and parallel to each other and partially overlapping the outer circumferences of the two lobes, and a housing having an inlet opening and an outlet opening and an inner and an outer wall, wherein the inner wall of the housing in each case encloses a portion of the outer peripheries of the rotary piston and wherein the rotary piston pump is adapted to convey the medium in a conveying direction from the inlet to the outlet opening.
- the German utility model DE 20 2006 020 1 13 U1 discloses a rotary lobe pump for the promotion of solids contained liquids.
- the utility model is based on the task of pumping liquids containing solids in such a way that damage in the pump, in particular to the rotary piston, is prevented.
- This task is realized by at least one specially designed ramp, through which the inlet is optimized. This optimization ensures that solids are directed into the pump chamber of the rotary lobe pump at a specific location.
- a reduction of the cavitation is achieved by the special design of the ramps in the inlet and outlet of the rotary lobe pump. In order to achieve the reduction of cavitation, an increase of the so-called housing angle is absolutely necessary.
- German Patent DE 94 751 A shows a capsule blower in which two counter-rotating pistons are moved, with which air is compressed and supplied to an outlet.
- the fan is provided with two special single-headed rollers C, each of which cooperates with a delivery piston so that each wing of the delivery piston is sealed by the roller C, causing the roller C to roll into the following gap and compress the air until the wing releases the outlet to the pressure chamber.
- the invention has for its object to provide a rotary piston pump, with a promotion is largely possible without pulsation.
- This object is achieved by a rotary piston pump comprising the features of claim 1. Further advantageous embodiments can be found in the features of the subclaims.
- the rotary lobe pump consists of a pump housing, which is provided with an inlet and an outlet.
- the pump housing has a lining.
- In the pump housing, or within the lining at least two oppositely rotating rotary pistons are arranged, which form pump chambers during their rotation.
- the rotary pistons are sealed against each other, against the pump housing and against the lining.
- In the pump housing and / or in the lining at least two recesses are arranged in each pump room. The recesses are arranged in spatial proximity to the inlet and / or outlet.
- the pump housing and / or the lining can have reinforcements, which lead to a reduction in cross-section.
- the reinforcements are designed at an angle of 20 to 1 60 degrees, preferably at an angle of 45 to 135 degrees.
- the inlet and outlet widen, from the reinforcements to their ends.
- the reinforcements preferably have a wrap of more than 180 degrees.
- each pump chamber In a particular embodiment, four recesses are arranged in each pump chamber, wherein the recesses are always arranged in pairs. In a further embodiment, there are six recesses in each pump room, the recesses then being arranged in each case as a trio. It will be apparent to those skilled in the art from the foregoing that these are not an ultimate limitation of the invention. It is possible that a plurality of recesses may be arranged in the pump chambers. It is also conceivable to arrange a different number of recesses in the two pump chambers. As the pump room, the average expert refers to the space that is created by the rotation of the rotary pistons in the
- Rotary pump forms This pump chamber, or the pump chambers, are located between the rotary piston and the pump housing.
- This pump chamber, or the pump chambers are located between the rotary piston and the pump housing.
- the pulsation of the rotary pump is avoidable.
- the pressure conditions in the pump chambers as well as in the inlet and / or outlet can be changed. These pressure changes reduce or completely eliminate the blows occurring in the inlet and / or outlet due to the pulsation.
- the expansion at the ends of the inlet and the outlet allows an optimized flow of the pumped medium, wherein the optimized flow, in combination with the recesses, causes an additional reduction of the pulsation.
- the combination of recesses and reinforcement is designed such that during operation of the rotary lobe pump results in an optimized flow, with energy losses in the promotion and dead spaces within the rotary lobe pump are almost completely avoidable.
- the spacing of the recesses from the inlet and / or the outlet is two to five times the cross section of the recesses.
- the recesses may have different cross sections. There may be a gap between the recesses.
- the depth of the recesses is at least ten to thirty percent of the wall thickness of the lining.
- the recesses may have different depths.
- the recesses in the inlet and outlet areas and in the multiple arrangement may have different cross sections and depths. It will be clear to those skilled in the art that the statements made above are not an exhaustive limitation of the invention. Rather, they refer to preferred embodiments. Due to the different number and configurations of the recesses, it is possible to change the pressure curves in the pump and thus the flows and the pulsation differently or avoided.
