摘要： A filter system includes a housing and a plurality of filter elements disposed in the housing. The plurality of filter elements includes one or more filter elements of a first filter element type and including one or more filter elements of a second filter element type. The system also includes a receptacle plate in the housing, the receptacle plate has at least two different mating elements for attaching filter elements thereto. The receptacle plate includes one or more first mating elements configured to mate with filter elements of the first type and one or more second mating elements configured to mate with filter elements of the second type.

摘要： A condition monitoring apparatus (300) for a system comprising rotating or reciprocating machinery and a seal is disclosed herein. The apparatus comprises a first acoustic sensor (301) coupled to the seal for providing a first acoustic emission signal, a second acoustic sensor (302) coupled to the rotating or reciprocating machinery for providing a second acoustic emission signal, and a filter module (310). The filter module is configured to perform active noise cancellation based on a comparison of the first acoustic emission signal and the second acoustic emission signal.

摘要： Coupling members to join two rotary members are described. The coupling members (300) include a unitary body having a first coupling element (302), a second coupling element (304), and a hub (306), wherein the unitary body forms a single piece with the hub (306) extending between and connecting the first coupling element (302) to the second coupling element (304). The first coupling element (302) defines a first plane, the second coupling element (304) defines a second plane with the first and second planes being parallel, and the hub (306) defines a hub axis normal to the first and second planes. Each of the first and second coupling elements (302, 304) comprises a plurality of connection elements (308, 310) arranged about a respective circumference having a respective radius extending from the hub axis, wherein a material of the respective coupling element in a respective circle and in a respective plane is less than the area of the circle. The material forming the first and second coupling elements (302, 304) is arranged in a respective circumscribing circle over an area less than the total area defined by the circle in the respective plane.

摘要： A system and method for monitoring a dry gas seal positionable between a stationary housing and a rotatable shaft. A plurality of sense elements may rotate in response to the rotation of the rotatable shaft and a speed sensor may sense the speed of the rotatable shaft at speeds below one thousand rotations per minute based on sensing the plurality of sense elements. An acoustic emissions sensor may sense when a first seal face and a second seal face forming a seal interface of the dry gas seal are in an operational condition relative to one another. A processor may receive output signals from the speed sensor and the acoustic emissions sensor, and may establish an operating condition of the dry gas seal based on the signal from the speed sensor when the first seal face and the second seal face reach the operational condition relative to one another.
