Abstract
A pump for conveying a medium having a suction-side inlet, a pressure-side outlet, a suction chamber, and a conveyance housing. The conveyance housing having a pressure chamber and a transport element. The transport element rotatably supported in the conveyance housing for conveying the medium from the suction chamber into the pressure chamber. The pump having a recirculation line via which the medium is supplied from the pressure chamber to the suction chamber, wherein an exchangeable insert having an unchanging flow area is arranged in the recirculation line.
Claims12
A pump for conveying a medium comprising:
- a suction-side inlet;
- a pressure-side outlet;
- a suction chamber;
- a conveyance housing comprising a pressure chamber;
- a transport element rotatably supported in the conveyance housing, wherein the transport element is configured to convey a medium from the suction chamber into the pressure chamber;
- a recirculation line configured to supply the medium from the pressure chamber to the suction chamber;
- and
- an exchangeable insert comprising a fixed flow area positioned in the recirculation line, wherein the exchangeable insert comprises a bolt configured to be screwed in, clamped in, or inserted.
A method for adjusting the delivery rate of a pump for conveying a medium, the method comprising:
- determining the effective delivery rate of a pump at a predefined speed of the transport element;
- determining the deviation of the effective delivery rate of the pump at the predefined speed of a transport element compared to a target delivery rate at the predefined speed of the transport element;
- and
- inserting an insert having a fixed flow area into a recirculation line, wherein the fixed flow area of the insert has dimensions such that the effective delivery rate of the pump at the predefined speed of the transport element corresponds to the target delivery rate at the predefined speed of the transport element.
A pump for conveying a medium comprising:
- a suction-side inlet;
- a pressure-side outlet;
- a suction chamber;
- a conveyance housing comprising a pressure chamber;
- a transport element rotatably supported in the conveyance housing, wherein the transport element is configured to convey a medium from the suction chamber into the pressure chamber;
- a recirculation line configured to supply the medium from the pressure chamber to the suction chamber;
- and
- an exchangeable insert comprising:
- a fixed flow area positioned in the recirculation line;
- and
- a longitudinal bore and a transverse bore that are fluidly connected to one another, wherein the medium travels from the pressure chamber into the exchangeable insert via the longitudinal bore and out of the insert into the suction chamber via the transverse bore.
