摘要： Systems, methods, and apparatuses for detecting a direction of rotation of a rotatable object are disclosed herein. An apparatus includes a sensor having a sensing field and being disposed so that the object is within the sensing field, the sensor being configured to detect variations in measured characteristics of the object as the object rotates, and generate a signal based on the detected variations in measured characteristics. The apparatus also includes a computing system configured to receive the signal from the sensor and to determine a direction of rotation of the object about the axis based on the signal.

摘要： A method to control an axial separation between a rotating ring and a stationary ring of a dry gas seal. The dry gas seal restricts leakage of a gas or other fluid to or from a rotating device. At least one property of the gas or other fluid is sensed. At least one of the axial separation between the rotating ring and the stationary ring, and a time rate of change of the axial separation, is sensed. A stiffness of a film between the rotating ring and the stationary ring is estimated. A field strength of at least one magnetic device is adjusted based on at least two of the sensed axial separation, the sensed time rate of change of the separation, and the estimated film stiffness. The axial separation between the rotating ring and the stationary ring is adjusted.

摘要： A method and system for actively controlling an axial separation between a seal face of a stationary ring and a seal face of a rotating ring of a gas seal is disclosed. At least one property is sensed indicative of a condition of at least one of the seal faces. With at least one sensing device, a characteristic of the axial separation between the seal faces is sensed. A net magnetic force of at least one magnetic device is adjusted based on the property and/or the characteristic. Adjusting the net magnetic force adjusts the axial separation between the seal faces. Without using a buffer gas between the seal faces, flow of gas or other fluid is controlled between the seal faces by adjusting the axial separation.
