摘要： Disclosed is a hydrocyclone monitoring system. The hydrocyclone monitoring system comprises a hydrocyclone comprising a separation chamber having an inlet for feeding an input mixture into the separation chamber and first and second outlets for ejecting flows of 5 respective first and second components of the mixture from the separation chamber. The hydrocyclone monitoring system further comprises a conduit and a sensor assembly. The conduit is connected to the first outlet and defines a channel for conducting the flow of the first component ejected from the separation chamber. The sensor assembly is configured to detect characteristics of the flow of the first component in the channel. The hydrocyclone 10 monitoring system further comprises a processing system configured to receive from the sensor assembly measurement data indicative of the characteristics of the flow of the first component, and to determine a mode of operation of the hydrocyclone based on the measurement data. Also disclosed is a method of monitoring a hydrocyclone.

摘要： A hydrocyclone (10) is disclosed which includes an internal conical separation chamber (15) which extends axially from a first end to a second end of relatively smaller cross-sectional area than the first end. The separation chamber (15) includes at least one gas inlet device (60) which comprises a plurality of openings in the form of a series of elongate slits (82) arranged in a spaced-apart relationship from one another around an interior circumferential wall (80) of the gas discharge chamber (74). In use the slits (82) are arranged for admission of gas into the separation chamber (15) at a region located between the first and second ends.

摘要： A method of operating hydrocyclone comprising a separation chamber which in use is arranged to generate an internal air core for affecting a material separation process, comprises measuring both a vibrational parameter of the separation chamber and a stability parameter of the internal air core during operation of the hydrocyclone. The measurements are compared against predefined corresponding parameters which are indicative of a stable operation of the hydrocyclone and an operational parameter of the hydrocyclone is adjusted dependent on the comparison.

摘要： A mechanical seal is disclosed having a rotatable sealing face and a stationary sealing face that are in opposed relation and arranged to be urged, into contact to form a seal. One of the sealing faces is mounted on a support assembly that includes a biasing device operative to move that sealing face into contact with the other sealing face. In one form of the invention, the biasing device comprises one or more resilient members that in use are deformed to provide the biasing force. In a second form of the invention, the support assembly forms part of a fluid barrier of the seal and the biasing device is fluid impervious and forms part of the barrier. In a third form of the invention, the biasing device is exposed to fluid pressure in the chamber and the biasing force increases on increasing the fluid pressure in the chamber.

摘要： The chamber (29A) of the overflow outlet control device (21A) has an inner circumferential surface which, when viewed in cross-sectional plan view, is generally in the shape of a volute, for directing material entering the chamber (29A) via the circular inlet (34) at the base portion (36) tangentially outward towards the discharge outlet (22A) located in the side wall (38). The top wall region (40) of the interior wall of the chamber (29A), a side wall portion (32) and base portion (36) together seamlessly form the chamber (29A) which is curved in shape internally. When material flows in use between the inlet (34) and the discharge outlet (22A), and passes through the central chamber (29A), it encounters no sharp corners or edges, but just smoothly curved or rounded interior wall surfaces. The top wall region (40) of the chamber (29A) also features a protruding flow control formation (42) which is joined or formed therewith, and which is arranged to extend into the chamber (29A), being directed face towards the inlet (34) such that in use the flow of material into the chamber (29A) via the inlet (34) directly encounters the formation (42).

摘要： 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.
