A separator includes a first piston and a second piston both mounted on a drum assembly. The first piston is moveable between a first piston open position and a first piston closed position. In the first piston open position drum ejection passages are open for ejection of material from a maximum diameter of a separator volume, while in the first piston closed position the first piston blocks the drum ejection passages to prevent the ejection of material from the maximum diameter of the separator volume. A number of intermediate ejection paths are formed in the separator, each extending from an intermediate ejection path inlet at an intermediate region of the separator volume to an intermediate ejection path outlet. The second piston is moveable to alternately open or close the intermediate ejection paths for fluid communication to the separator volume.

A piston for centrifugation according to one embodiment may include: a body; a valve which can move inside the body to the front side and the rear side of the body according to an applied external force; a fluid channel through which a fluid flows from the front side of the body to the rear side of the body; and a valve support for guiding movement of the valve.

A material separation system is disclosed that may include a vibratory shaker, a centrifuge, a sensor, and/or a processor circuit. The vibratory shaker may be configured to separate a solid-liquid mixture into a first solids-containing component and a shaker effluent. The sensor may be configured to measure a property of one or more of the solid-liquid mixture, the first solids-containing component, the shaker effluent, and the second solids-containing. A well-performance analysis system may be configured to analyze mud reports of drilling rigs within a geographic basin to determine which rigs are performing inefficiently. The system may allow recommendations and send control signals to improve the efficiency of the solid-liquid separation system. The system may allow an operator to view agglomerated well performance data to identify which rigs are performing below a geographic basin baseline and make informed decisions to improve the functioning of a solid-liquid separation system associated with one or more drilling rigs.

The first piston is moveable between a first piston open position and a first piston closed position. In the first piston open position drum ejection passages of the drum assembly are open to the drum assembly volume, while in the first piston closed position the first piston blocks the drum ejection passages so that they are closed to the drum assembly volume.

The second piston is moveable to alternately open or close the intermediate ejection paths to the drum assembly volume.

A self-emptying separator includes a rotatable drum with an inlet, a liquid outlet, outlet openings for solid material, and a control system. A flowable starting product is cleared of the solids in continuous operation in a centrifugal field in the rotating drum. A continuous discharge of a clear phase is performed. A solid phase is discharged via the outlet openings from a solids collecting space of the drum into an annular solids catcher. The solids catcher has a device for generating a fluid curtain against which the solids, issuing from the outlet openings for solid material, impact.

An outlet nozzle for centrifugal drums has a nozzle body with at least one cylindrical portion and having an insert connected to the nozzle body. An inlet channel and an outlet channel, which is oriented at an angle with respect to the inlet channel, are formed in the nozzle body. The insert has a torque transmitting contour for arranging a tool with a complementary tool torque transmitting contour in position in order to rotatingly secure the nozzle body in an opening of a rotatable centrifugal drum and to release said nozzle body. The insert also has a polygonal cross-section, which is smaller than the cross-section of the cylindrical section. The insert starting from the polygonal, in particular, rectangular cross-section, merges with the cylindrical section of the nozzle body over rounded surfaces having a radius greater than 1.0 mm.

A centrifugal separation container which is revolved around a rotation axis, includes: a separation part which includes a distal region which is disposed on a distal side than a liquid-to-be-treated supply port and a proximal region which is disposed on a proximal side than the liquid-to-be-treated supply port, with respect to the rotation axis, and in which a liquid-to-be-treated discharge port is provided in the proximal region; and a recovery part which is disposed on a distal side than the distal region with respect to the rotation axis, communicates with a distal end portion of the distal region through a communication path, and is filled with a recovery liquid for dispersing dispersoids that are to be centrifuged in a liquid to be treated.
