Abstract
A gas-liquid rotating separator has first and second sets of magnetically permeable members magnetically interacting with each other to effect rotation of a separator element. A nonauthorized replacement separator element missing the second set of magnetically permeable members will not effect designated operation, thus ensuring, at maintenance servicing, installation of an authorized replacement separator element.
Claims38
A gas-liquid rotating separator separating liquid from a gas-liquid mixture, comprising:
- a separator assembly comprising a housing having an inlet receiving said gas-liquid mixture, a gas outlet discharging separated gas, and a drain outlet discharging separated liquid,
- a rotating separator element in said housing and effecting separation of gas and liquid, said separator element positioned within said housing such that a circumferential surface of said separator element forms a gap with an inside surface of said housing,
- a first set of one or more magnetically permeable members provided on an exterior surface of said housing, and
- a second set of one or more magnetically permeable members provided on said circumferential surface of said separator element, said first and second sets of magnetically permeable members magnetically interacting with each other to effect rotation of said separator element,
- wherein designated operation of said separator including rotation of said separator element requires both of said first and second sets of magnetically permeable members, including said second set of magnetically permeable members on said separator element, and
- wherein said separator element rotates about an axis and extends axially along said axis between first and second axial ends having respective first and second axial endcaps that rotate about said axis, said second set of magnetically permeable members is on said second axial endcap, and said first set of magnetically permeable members is on said housing proximate said second axial endcap.
