Self-driven, cone-stack type centrifuge

Nozzle inlet enhancement for a high speed turbine-driven centrifuge

A cone-stack centrifuge for separating particulate matter out of a circulating liquid includes a cone-stack assembly which is configured with a hollow rotor hub and is constructed to rotate about an axis. The cone-stack assembly is mounted onto a shaft centertube which is attached to a hollow base hub of a base assembly. The base assembly further includes a liquid inlet, a first passageway, and a second passageway which is connected to the first passageway. The liquid inlet is connected to the hollow base hub by the first passageway. A bearing arrangement is positioned between the rotor hub and the shaft centertube for rotary motion of the cone-stack assembly. An impulse-turbine wheel is attached to the rotor hub and a flow jet nozzle is positioned so as to be directed at the turbine wheel. The flow jet nozzle is coupled to the second passageway for directing a flow jet of liquid at the turbine wheel in order to impart rotary motion to the cone-stack assembly. The liquid for the flow jet nozzle enters the cone-stack centrifuge by way of the liquid inlet. The same liquid inlet also provides the liquid which is circulated through the cone-stack assembly. A honeycomb-like insert is assembled into the flow jet nozzle in order to reduce inlet turbulence and improve the turbine efficiency.

Methods and apparatuses for missing filter detection and prevention in rotating coalescer designs

Systems and methods for detecting a missing coalescing element in a CV system are described. In some arrangements, the described systems and methods prevent the assembly and/or re-assembly of the CV system without an appropriate coalescing element positioned within the CV system housing (e.g., during a coalescing element service operation). In some arrangements, the coalescing element depresses a spring-loaded component of a shaft that provides flow of bypass gases to the CV system. If the spring-loaded component is not depressed, significant restriction is introduced to the CV system, and an on-board-diagnostic system may detect high-crankcase pressure through existing crankcase pressure sensors and de-rate the internal combustion engine. In other arrangements, a spring-loaded mechanism within the shaft prevents a housing cover (e.g., a lid to the housing of the CV system) from being repositioned when a coalescing element is not installed within the housing.
