  • Patent number: 11986841
    Abstract: A centrifuge rotor includes a rotor body having a base, a sidewall, and a top. The top defines an opening that provides access to an annulus cavity inside the rotor body. A cover is removably attachable to the rotor body to seal the annulus cavity. A drive hub extends from a portion of the base of the rotor body and couples to a drive shaft of a centrifuge motor. The rotor body is sized to receive one or more sample containers in the annulus cavity, and to constrain the one or more sample containers inside the annulus cavity between the base, the sidewall, and the top when the one or more containers are advanced radially against the sidewall.

  • Patent number: 11958063
    Abstract: Damage caused by displacement of a rotating shaft is prevented with an acceleration sensor. A centrifuge according to the present invention includes a rotor, a driving source that rotates the rotor, a rotating shaft that links the rotor with the driving source, an acceleration sensor, and a control unit. The acceleration sensor outputs a value indicating acceleration in at least two different directions which are orthogonal to an axial direction of the rotating shaft. The control unit obtains a displacement conversion value corresponding to a value, which is obtained by dividing a value which is proportional to acceleration based on a value indicating acceleration and outputted by the acceleration sensor, by a value which is proportional to a square of an angular velocity of the rotor, and stops rotation of the rotor when the displacement conversion value satisfies a displacement determination criterion which is predetermined and indicates that displacement is large.

  • Patent number: 11944986
    Abstract: A device and a method for reducing wind resistance power of a large geotechnical centrifuge are provided. A semicircular tube cylindrical cooling device is provided between an internal side of a high-speed rotor system and a cylindrical shell. A serpentine top semicircular tube cooling plate is provided right above a hanging basket, and return helium gas inlet holes are provided at a center of the top semicircular tube cooling plate. A helium gas in a helium gas storage tank passes through helium gas outlets on the helium gas inlet pipes, and enters a centrifuge chamber from a bottom sealing plate. The helium gas is used to replace air in the centrifuge chamber to reduce the wind resistance power and corresponding energy consumption. No vacuuming is required, so sealing requirements are lower. Heat dissipation equipment is placed inside the centrifuge chamber, and a helium gas circulation wind duct is added.
