| 摘要 |
The invention relates to a pump for pumping a liquid, comprising a hydraulic unit (1), which comprises a pump housing (2), an insert ring (3) and an impeller (4) arranged to rotate in said pump housing (2), the hydraulic unit (1) comprising an upstream inlet opening (9) and a downstream outlet opening (10) and delimiting in succession an inlet (11), a pump chamber (12) and an outlet (13), the insert ring (3) being connected to the pump housing (2) in the area of the transition between said inlet (11) and said pump chamber (12) and is displaceable in the axial direction in relation to said pump housing (2), the insert ring (3) being in threaded engagement with the pump housing (2) and being turnable in relation to said pump housing (2), and at least one locking member (19) is arranged at the interface between the insert ring (3) and the pump housing (2). The pump is characterized in that the insert ring (3) is right-threaded and the direction of rotation of the impeller (4) is counter-clockwise, when seen from the upstream inlet opening (9). |
