VERTICAL PUMP HAVING DISCHARGE HEAD WITH FLEXIBLE ELEMENT Russian patent published in 2018 - IPC F04D29/60 F04D13/10 F04D29/66 

FIELD: non-displacement compressors and pumps.

SUBSTANCE: group of inventions relates to a discharge head and a vertically suspended pump having such a head. Discharge head (10) comprises motor mounting plate (22) and support plate (24), rigid elements (12, 14) having bearing housing (14) and motor support (12) with supporting struts (12a, 12b, 12c, 12d) configured for connecting motor mounting plate (22) and the support plate (24) and having spacers (15a, 15b, 15c, 15d), configured for connection of bearing housing (14) and support struts (12a, 12b, 12c, 12d). Elements (12, 14) are configured, in response to significant forces from the pipeline, applied in a direction perpendicular to the centre line (CL) of head (10), do not substantially deflect. At least one elastic element having discharge elbow (16) is configured to deflect in response to significant forces from the pipeline. Elbow (16) is connected to plate (24). Element (20) is configured for connecting body (14) and elbow (16) and is flexible in the direction perpendicular to the line (CL) to cancel the pressure so that the deflection of elastic elements (16, 20) is substantially not transmitted to rigid elements (12, 14).

EFFECT: inventions are aimed at extending the service life of the pump.
