Embodiment Construction

[0033] figure 1 A screw pump 1 is shown schematically, designated by reference numeral 1 . according to figure 1 The drawing shows a progressive cavity pump 1 comprising a multi-part housing 2 . The housing 2 comprises an operating housing part 7 and a connecting housing part 15 as well as a drive housing part 21 .

[0034]In addition to these housing parts 7 , 15 , 21 further housing parts may be provided for connection to said housing parts 7 , 15 , 21 . Thus, a discharge housing may be provided for assembly on the housing parts 7, 15, 21, wherein the discharge housing preferably comprises means to allow the screw pump 1 to be drained for maintenance. Furthermore, an attached housing including a flushing connection can be provided for inspection and cleaning of the progressive cavity pump 1 . It is also possible to use a pressure limiting valve housing and a bypass housing for assembly on the modular housing parts 7 , 15 , 21 of the progressive cavity pump 1 . Furthermo...

Abstract

The invention relates to a screw pump (1), in particular a double screw pump, comprising a multiple-piece housing (2, 7, 15, 21) and at least two coupled rotors (3, 3a) which form chambers with in each case at least one thread-shaped profile (4, 4a) which is configured at least in regions with helical channels (5, 5a) and with dividing walls (6, 6a) which delimit the channels (5, 5a), wherein therotors (3, 3a) perform an opposed rotor rotation, and the dividing walls (6, 6a) engage into one another in a gearwheel-like manner, a running housing part (7), wherein the running housing part (7) encloses the rotors (3, 3a) without contact, wherein the rotors (3, 3a) form, with the running housing part (7), at least one conveying chamber (8, 8a) for the fluid to be conveyed, wherein the conveying chamber (8, 8a) migrates axially along the rotor axis (10, 10a) and conveys the fluid from a suction chamber (11) into a pressure chamber (12), a suction-side connector element (13) which is connected fluidically to the suction chamber (11), and a pressure-side connector element (14) which is connected fluidically to the pressure chamber (12), wherein the suction-side connector element (13) andthe pressure-side connector element (14) are arranged on a connector housing part (15) of the multiple-piece housing (2, 7, 15, 21), wherein the housing (2, 7, 15, 21) has a planar dividing plane (16)which runs parallel to the rotor axes (10, 10a) between the running housing part (7) and the connector housing part (15).

Description

technical field [0001] The present invention relates to a screw pump or screw shaft pump, in particular a single-flow or multi-flow twin screw pump or twin screw shaft pump, comprising: a multi-part housing and at least two coupled chamber-forming rotors, each rotor comprising at least one thread-like profile formed at least in regions and having a helical channel and a partition wall delimiting the channel, wherein the rotor performs a counter-rotor rotation and the partition walls mesh with each other in the manner of a gear; and a running housing body part, wherein the running housing part surrounds the rotor in a non-contact manner, wherein the rotor together with the running housing part forms at least one delivery chamber for the fluid to be delivered, wherein the delivery chamber is displaced axially along the rotor shaft, and A fluid is conveyed from the suction chamber to the pressure chamber; a suction side connection element is fluidly connected to the suction chamb...
