摘要： A cooling system provided for a motor powering a compressor in a vapor compression system. The cooling system includes a housing enclosing the motor and a cavity located within the housing. A fluid circuit has a first connection with the housing configured to provide a liquid or two phase cooling fluid to the motor. The two phase cooling fluid is separable into a vapor phase portion and a liquid phase portion. The fluid circuit further has a second connection with the housing to remove cooling fluid in fluid communication with the fluid circuit. The cooling fluid conveyed through the second connection is two phase cooling fluid. The fluid circuit further has a third connection with the housing for receiving and circulating in the cavity the vapor phase portion conveyed through the second connection.

摘要： Apparatus and method for determining the clearance and wear of mechanical back-up bearings of turbomachinery utilizing electromagnetic bearings. In order to reduce the prospects of catastrophic failure during a shut-down or loss of electrical power, a rotating apparatus utilizes the electromagnetic bearings to manipulate the shaft to measure the clearance of the mechanical back-up bearings. When power is restored, a programmable controller provides power to the electromagnetic bearings to automatically move the shaft in accordance with a predetermined sequence to contact the mechanical back-up bearings to determine the clearance of the mechanical back-up bearings. These values are stored in the controller memory. The measured clearance is compared to prior clearance measurements of the mechanical back-up bearings to determine the wear of the back-up bearings. The actual wear is compared to the allowable wear for the bearings. If actual wear exceeds a predetermined value, a warning is generated. If the actual wear equals or exceeds the allowable wear, the controller automatically locks the turbomachinery from further operation until repair or replacement is accomplished. Otherwise, the controller centers the shaft to permit normal operation of the turbomachinery.
