rotating verdrängerpumpe with weichpackungsabdichtung promoting liquids with feststoffanteilen

摘要

rotating verdrängerpumpe with weichpackungsabdichtung, particularly to promote its fördermedien with solids.with a in a förderraum (1) positioned pair of synchronously driven rotors (6), a rotor (6) arranged respectively on each wave (4)5) each with a rotationsdrehachse (7) and with a dichtungsraum (3) positioned weichpackungsdichtung,a comprehensive spannelement (15) and at least one weichpackungsring (8) with a mid plane (m) and an axial width (b), characterizedat least a weichpackungsring (8) on the mid plane (m) at an angle (a) to the axis (7) is arranged.although the axial component (b) of the angle (a) of at least the axial width (b) of a weichpackungsringes (8) isand with the packungsspannung perpendicular to the rotation axis (7) and to create the tension in a radial direction, an elastic dichtring (9) is provided.
