Abstract
A part-conical section (20,22) for use as part of a separation chamber (14) of a hydrocyclone (10) is described. The part-conical section comprises: an upper end defining internal and external diameters and including an upper mount (44,48); a lower end defining smaller internal and external diameters than the upper end, and including a lower mount (46,50); and a side-wall (26) defining an internal passageway (28) along a fluid transport axis (30) and an external surface. The internal passageway extends from the upper end to the lower end and defines a radially-inward tapering portion with respect to the fluid transport axis, and a non-inwardly-tapering portion with respect to the fluid transport axis. The tapering portion extends from the upper end to the non-inwardly-tapering portion, and the non-inwardly-tapering portion extends from a narrow end of the tapering portion to the lower end. A spigot (24) and a hydrocyclone (10) are also described.
