Definitions

  • the present disclosure relates generally to systems, devices, and methods for processing samples comprising particles. More specifically, the present disclosure relates to systems, devices, and methods for separating particles within particle containing samples based upon particle size. Many embodiments of the present disclosure facilitate a controlled, coordinated, and/or simultaneous processing of multiple samples.
  • the systems and devices of the present disclosure include at least two (i.e., multiple) chambers, channels, or ports, wherein each chamber, channel, or port is configured to receive a sample and mediate separation of particles of said sample based upon particle size.
  • Wear is an unavoidable occurrence in machine systems and components.
  • the ability to measure wear is essential for implementing effective predictive maintenance programs, and for determining safety factors and performance ratings.
  • the first option for measuring wear in a machine system is via interceptive or disruptive means whereby the machine system is disassembled and wearing surfaces of the machine system visually examined. Measuring wear via such interceptive means disrupts the overall operation of the machine system and can result in a loss of productivity and increased costs.
  • the second option for measuring wear in a machine system is via non-interceptive techniques such as wear particle analysis, which is also known as lubricant analysis. In wear particle analysis, a lubricant sample, for instance an oil sample, is taken from the machine system and tested separately.
  • wear particle analysis is particularly useful for measuring wear of such systems.
  • Common wear particle analysis techniques include spectroscopic analysis, ferrography, filter patch analysis, and magnetic chip detector (MCD) wear particle analysis.
  • a known wear analysis tool is the 51 WD Wear Debris Filter Patch Maker from Emerson Process Management.
  • the 51 WD Wear Debris Filter Patch Maker is designed to separate wear particles from used oil samples for viewing under a microscope.

  • the 51 WD Wear Debris Filter Patch Maker There are several limitations associated with the 51 WD Wear Debris Filter Patch Maker. For instance, a single use of the 51 WD Wear Debris Filter Patch Maker only supports or allows for processing or analysis of a single oil sample. In addition, the number of filter patches that can be carried by a particular 51 WD Wear Debris Filter Patch Maker is largely limited. Accordingly, the 51 WD Wear Debris Filter Patch Maker generally only supports or allows separation of wear particles based upon a limited number of different particle sizes. The limitations associated with the 51 WD Wear Debris Filter Patch Maker result in a relatively low efficiency associated with the use of the 51 WD Wear Debris Filter Patch Maker.

Abstract

L'invention concerne un système, un dispositif et un procédé pour le traitement de particules, plus spécifiquement la séparation de particules selon la taille des particules. Le dispositif comprend un module de traitement qui comprend une pluralité d'orifices de séparation, chaque orifice de séparation parmi la pluralité d'orifices de séparation étant conçu pour recevoir des échantillons comprenant des particules. Le dispositif permet de traiter simultanément des échantillons multiples pendant le fonctionnement, plus spécifiquement la centrifugation, du module traité. Chaque orifice de séparation peut communiquer de façon fluidique avec un espace (par exemple un espace de collecte d'échantillons) défini par un module de logement du dispositif. L'introduction d'échantillons dans la pluralité d'orifices de séparation peut être commandée. Un échantillon résiduel reçu ou collecté par le module de logement peut être retiré du module de logement ou drainé depuis le module de logement pendant la centrifugation du module de traitement.
