Definitions

  • the invention relates to a modular system for producing a screw pump.
  • Such screw spindle pumps are used, for example, to pump oils or other more or less lubricating liquids.
  • a screw spindle pump consists of a housing and a drive spindle accommodated therein, which meshes with one or two running spindles accommodated on the housing side.
  • the spindles form sealed chambers due to the interlocking thread flanks. If the drive spindle is rotated, the running spindles also rotate automatically. This means that the sucked liquid in the chambers is conveyed axially and continuously from the suction side to the pressure side of the pump and is released there via the outlet.
  • the publication US2014/099225 A1 discloses a modular multistage screw pump.
  • Such screw spindle pumps are known in different designs for specific pressure levels, for example low pressure, medium pressure, high pressure, ultra-high pressure, etc.
  • the corresponding components are manufactured separately for each pressure level and designed in the required length. This means that a pump body of the appropriate length as well as appropriately sized drive and running spindles are manufactured for each pressure stage. Both the pump body and the spindles are made in one piece.
  • the required overall length and thus the design of the screw spindle pump varies depending on the requirements with regard to the desired differential pressure, the viscosity of the fluid to be pumped, etc. Particularly with larger or longer pumps, the machining of the corresponding components becomes more difficult due to the increasing component length and thus the machining length, which Manufacturing such screw spindle pumps is complex.
  • the invention is therefore based on the problem of specifying an improved screw spindle design.
  • the modular system according to the invention for configuring a screw spindle pump makes it possible to produce a screw spindle pump with a selectable pump length solely from standardized components that are the same for all pump sizes that can be produced.
  • the only non-modular pump component is the drive spindle, which must be manufactured as a one-piece component according to the desired pump size.
  • the modular system includes a housing base component. This has the fluid inlet, i.e. the suction side, and forms a base pump chamber, which at the same time forms the smallest pump chamber of the smallest pump size that can be produced.
  • the system further comprises a housing pressure component which forms the pressure chamber and which has a fluid outlet in order to release the suctioned and delivered fluid back out of the pump with the corresponding pump pressure.
  • the drive spindle is mounted and sealed in this housing pressure component.
  • the system includes a housing cover that can be arranged on the housing base component and which closes the housing component on this side (on the opposite side it is closed via the housing pressure component).
  • the running spindle or spindles are usually supported hydrostatically on the housing cover for axial thrust compensation.
  • the housing base component, the housing pressure component and the housing cover are the three components that, when it comes to the configuration of the housing, are installed in every pump size that can be manufactured.
  • the system includes a plurality of identical intermediate housing components, which can be installed in any number between the housing base component and the housing pressure component. These intermediate housing components therefore extend the base pump chamber by the corresponding length of one or more additional pump chambers, depending on how many of these identical intermediate housing components are placed between the housing base component and the housing pressure component.
  • each housing intermediate component has corresponding bores for receiving the continuous drive spindle and the running spindles.
  • the smallest pump size is defined in its working length by the housing base component and the housing pressure component attached to it.
  • the next larger pump size then has one between the housing base component and Housing pressure component placed on the housing intermediate component, so that the pump room is formed from the base pump room and an extending additional pump room.
  • the next pump size is characterized by two intermediate housing components so that the pump chamber is defined by the basic pump chamber and two additional pump chambers that extend it. In this way, by continuously integrating additional intermediate housing components, the length of the pump housing can be continuously expanded, up to a maximum pump length, which is ultimately defined by the maximum producible length of the drive spindle, which is manufactured in one piece as described.
  • the one or two running spindles are also constructed modularly from standardized running spindle elements.
  • the system comprises a plurality of running spindle elements and, among these, one or two running spindle base elements that can be arranged in the housing base component.
  • This or these barrel spindle base elements are the spindle elements to be used with every pump size.
  • Their length is dimensioned according to the spindle bore length of the housing base component and, when installed, is arranged in the housing base component, i.e. the base pump room. With the smallest pump size, the or each running spindle is formed by only one running spindle base element.
  • the respective running spindle must also be lengthened. This is done via a plurality of identical running spindle extension elements, which are each arranged in the housing intermediate component or components, depending on how many are arranged between the housing base component and the housing pressure component.
  • the number of intermediate housing components corresponds to the number of running spindle extension elements per running spindle.
  • the running spindle can also be modularly configured to any length corresponding to the length of the pump housing.
  • the modular system according to the invention therefore consists of a series of standardized components, namely the standardized housing components and the standardized running spindle elements.
  • Every pump that can be produced always has a housing base component, a housing cover, a housing pressure component and a running spindle base element as well as of course the corresponding one-piece drive spindle that is manufactured to suit pump types.
  • the possibility of extending the pump is made possible via the standardized, identical housing intermediate components as well as the standardized, identical running spindle extension elements. This makes it possible to produce screw spindle pumps of different lengths and different performance, with only the drive spindle having to be manufactured in the appropriate length for each size.
  • this modular system also offers other advantages, for example with regard to the production of the corresponding components or identical parts. This is because significantly shorter components or spindle elements have to be produced compared to the one-piece parts previously known in the prior art, so that part production is simplified. At the same time, the manufacturing quality of the pump produced remains high regardless of the component length, as only short, standardized parts can be manufactured.
  • the design of very long pumps, e.g. B. possible for very high pressures regardless of production, and warehousing and parts management is considerably simplified, as only the short, standardized parts, of which a large number can be produced in stock, have to be kept in stock.
  • the division of the housing components and the running spindle elements is identical. This means that the parting planes of the housing components and the parting planes of the running spindle elements coincide. This applies regardless of whether the pump consists of the housing base component, the housing pressure component and only one intermediate housing component, or whether a plurality Such intermediate housing components and inevitably a plurality of running spindle extension elements are installed.
  • This division identity has advantages with regard to the hydrostatic sliding bearing of the running spindle elements in the housing components.
  • the running spindle elements are hydrostatically mounted at a small distance of just a few micrometers, i.e. they are slide-mounted on the bore wall of the respective housing component via a lubricating film.
  • the parting plane of the running spindle elements also lies in this parting plane area.
  • Appropriate measures on the part of the running spindle element configuration can ensure that the running spindle elements do not come into direct contact with the housing wall in this area, but that there is always a hydrodynamic sliding bearing.
  • the running spindle extension elements and the running spindle base element(s) merely lie against one another with their flat end faces. This means that the spindle elements are not firmly connected to one another, but simply rest against one another axially, i.e. they are infinitesimally radially movable relative to one another. There is no need for a connection since the running spindle elements are in engagement with the thread of the drive spindle with their thread flanks and they are carried along here.
  • the specific spindle element position can be adjusted exactly in relation to the respective bore wall of the respective housing component, after, if necessary, a minimal compensation in the micrometer range, if necessary. is possible.
  • the intermediate housing components have axial through holes with a front screw head recess and axial ones in an arrangement distributed around the circumference Have threaded holes, the through holes and the threaded holes being provided in an alternating arrangement.
  • This hole pattern makes it possible to connect the intermediate housing components, which are to be arranged in a correspondingly rotated position relative to one another, to one another and also to connect them to the housing base component and the housing pressure component.
  • the corresponding connecting screws are passed through the through holes with the front screw head recess through the one intermediate housing component and screwed into the front axial threaded holes of the adjacent intermediate housing element. In this way, any number of intermediate housing elements can be integrated and connected to one another.
  • threaded holes also makes it possible for corresponding connecting screws, which are guided through the housing pressure component, to be screwed into the adjacent intermediate housing component.
  • connecting screws of the intermediate housing element adjacent to the housing base component, guided through the corresponding through holes, can be screwed into corresponding threaded holes in the housing base component.
  • the housing pressure component itself can preferably consist of two housing pressure component elements that are axially connected or connectable to one another via screw connections. As stated, on the one hand, the pressure chamber and fluid outlet are provided in the housing pressure component, but on the other hand, the storage and sealing of the drive spindle is also implemented. The design of these different functional sections is easier if the housing pressure component is designed to be modular and consists of these two standardized housing pressure component elements that are identical for all sizes.
  • housing pressure component for connection to the housing base component in the case of the smallest pump size or an adjacent housing intermediate element are optionally designed with front screw head recesses. This is possible with a one-piece design of the housing pressure component.
  • the housing pressure component is also designed modularly from two housing pressure component elements
  • a corresponding bore configuration with through holes and threaded holes in the corresponding housing pressure component elements is also suitable in this case.
  • only through holes are preferably formed on the axially outer housing pressure component element, which are optionally formed with front screw head recesses, and on the axially inner housing pressure component element, in an arrangement distributed around the circumference, axial through holes with a front screw head recess and axial threaded holes are formed, the through holes and the threaded holes in are provided in an alternating arrangement.
  • this configuration makes it possible to connect the axially terminal housing pressure component element with the adjacent second housing pressure component element.
  • the connecting screws are passed through the through holes provided in the outer housing pressure component element and screwed into the threaded hole of the adjacent housing pressure component element.
  • additional axial through-holes with a front-side screw head recess are provided.
  • the connecting screws are guided through these through holes for connection to the housing base component or the adjacent housing intermediate element, which are screwed into the threaded holes there.
  • a distributed, alternating arrangement of threaded holes and through holes is useful.
  • the housing base component for its part, is only provided with threaded holes on both axial end faces. On the one hand, these make it possible to attach the Housing cover, which has corresponding through holes, through which corresponding connecting screws are passed, which are screwed into the threaded holes of the housing base component. From the other side, the connecting screws, which pass through either the housing pressure component or the internal housing pressure component element, or which pass through the adjacent housing intermediate element, are screwed in.
  • the length of the running spindle base elements is expediently greater than the length of the running spindle extension elements.
  • the housing base component forms the base pump chamber; it must be dimensioned accordingly long since the fluid inlet is also provided on it. In contrast, the intermediate housing elements and the additional pump rooms formed via them are somewhat shorter.
  • the ends of the running spindle base elements arranged adjacent to the housing cover are accommodated in compensating sleeves which serve to compensate for an axial thrust.
  • a usually hydrostatic axial thrust compensation takes place in the running spindle base element, for which purpose the corresponding compensating sleeves are provided, which are placed on the ends of the running spindle base elements and run with their sleeve end surfaces adjacent to the housing cover.

  • the housing base component 4, the housing intermediate elements 6 and the housing pressure component elements 9, 10 have corresponding bores on the one hand, to accommodate the drive spindle, not shown, and to store and seal it in the case of the housing pressure component 8, and to accommodate the corresponding running spindles, formed from the running spindle base elements 5 and the running spindle extension elements 7.
  • the housing base component 4 has a fluid inlet 11 and forms a base pump space.
  • the housing pressure component 8 has a fluid outlet 12 on the housing pressure component element 9. It also forms a pressure chamber with the housing pressure component element 9, which communicates with the fluid outlet 12.
  • the intermediate housing components 6 and the running spindle extension elements 7 are identical to one another. This and the fact that for every pump size that can be produced using the modular system 1, the housing cover 2, the housing base element 4 and the housing pressure component or the housing pressure component elements 9 and 10 must always be installed, means that any pump size can be produced from corresponding identical parts.
