摘要： A method for determining the torque of a worm of a solid bowl worm centrifuge. The solid bowl worm centrifuge includes a rotatable drum and a rotatable worm, the rotatable worm being rotatable at a different rotational speed than that of the rotatable drum. The rotatable drum and rotatable worm are driven via a gear arrangement and a common single drive motor via at least one belt drive, a driving belt pulley, a driven belt pulley and a belt coupling the pulley. The method steps include determining a slip of the at least once belt drive and calculating a torque based upon the determination of the slip.

摘要： A control system for a centrifuge that allows the centrifuge to continue to run when there is a short duration failure or outage of the AC power source. The control system allows the centrifuge to be brought to a stop in a normal shutdown mode where there are longer duration failures or outages of the AC power source. This allows power to be maintained to the pump that lubricates the centrifuge bearings so that the bearings are lubricated during the coast down of the centrifuge and the differential speed of the centrifuge to be controlled during coast down allowing the centrifuge bowl to be cleared of solids so that the centrifuge can be immediately started up at lower vibration levels once power is restored.

摘要： A decanter centrifuge is disclosed for separating a liquid feed mixture into constituent parts. The decanter centrifuge includes a bowl assembly mounted for rotation about a longitudinal axis. Opposite ends of the bowl assembly are rotatably supported by first and second bearings. A motor is engaged with one end of the bowl assembly for rotating the bowl about the longitudinal axis. A screw conveyor is coaxially mounted within the bowl with a conveyor shaft attached thereto. A gear box is located between the second bearing and the bowl and includes a transmission engaged to the shaft. The transmission rotates the conveyor at a relative speed with respect to the bowl. A plurality of circumferentially spaced posts mount the gear box to the bowl, spacing the gear box apart from the bowl. Effluent discharge ports on the bowl discharge effluent into the space between the bowl and the gear box.

摘要： In a decanter centrifuge having a rotor (1) and a screw conveyor (2) the rotor is suspended only at its one end, the rotational axis (R) of the rotor extending vertically. The inlet (22) of the rotor (1) for a sludge containing liquid to be separated as well as the rotor outlet (12; 67) for liquid having been freed from sludge are situated at the upper end of the rotor, whereas a sludge outlet (13) for separated sludge is situated at the lower end of the rotor. The rotor (1) as well as the screw conveyor (2) are adapted to be driven through shafts (5, 8) situated at the upper end of the rotor. By the invention it becomes possible by simple means to adapt the decanter centrifuge for different separation duties, since the location of the sludge outlet (13) can be chosen freely without other parts of the decanter centrifuge preventing this.

摘要： A screw decanter centrifuge including a cylindrical bowl rotatable in one direction, a main drive motor coupled to the bowl for rotatably driving the bowl, a screw conveyor which is disposed concentrically in the bowl and which is rotatable in the same direction as the bowl at a differential rotation speed from the bowl, and an induction type screw conveyor motor for driving the screw conveyor. The differential rotation speed is changed in response to a carrying torque of the screw conveyor. An induction type screw conveyor motor is provided for driving the screw conveyor. The induction type screw conveyor motor has a shaft connected directly to, or coupled to, a shaft of the screw conveyor, and the induction type screw conveyor motor is controlled by a speed-torque controller. The speed-torque controller includes a speed controller for calculating the differential rotation speed based on rotations indicated by an induction motor tachometer for detecting a speed of the induction type screw conveyor motor, and on rotations indicated by a bowl tachometer for detecting a speed of the bowl. The speed-torque controller further includes a vector control inverter for independently controlling an exciting current and a torque current of the induction type screw conveyor motor based on a speed command value outputted from the speed controller and an actual speed of the induction type screw conveyor motor outputted from the induction motor tachometer.

摘要： A three stage centrifuge especially adapted to the separation of oil, water, and solid particles in an emulsion. As an example, the centrifuge may be used to separate sediment and water from a petroleum product such as crude oil. The three stage centrifuge includes a rotatable bowl that spins the emulsion to separate the fluid oil and water into separate pools within the bowl. The solid particles are also moved radially outward within the rotatable bowl by centrifugal force. A conveyor auger contacts the solid particles and discharges the solids from the rotatable bowl through a solids discharge port. Oil discharge tubes contact the oil pool confined between oil baffle plates on the conveyor auger and allow the oil to be discharged from the rotatable bowl. Water weirs contact the water pool and allow the water to be discharged from the rotatable bowl.
