摘要： A method for predicting surge in a compressor is provided, which is applicable to a cooling apparatus equipped with a centrifugal compressor. A set of highest outlet pressure values is obtained by a performance test performed on the centrifugal compressor. A coolant flow rate value and an opening percentage value of inlet guide vanes of the centrifugal compressor are measured. An outlet pressure value of the centrifugal compressor is calculated with an equation using the measured coolant flow rate value and the measured opening percentage value. The outlet pressure value is compared with one of the highest outlet pressure values corresponding to the measured opening percentage value, and if the outlet pressure value is larger than or equal to the highest corresponding outlet pressure value, it confirms imminent surge in the centrifugal compressor, so as to provide a basis of preparation for surge elimination.

摘要： A rotor mechanism of a centrifugal compressor connectable to a power output device and configured to block leakage of lubricants and to recycle lubricants to an oil sump is provided, which includes a rotary shaft with a rolling bearing and a screw nut, a bearing housing for receiving the rolling bearing, and a bearing plate connected to the bearing housing. The screw nut has a surface provided with an oil throw seal, and the bearing housing. As the bearing plate is provided with an oil channel in contact with the oil-returning hole and either one of the bearing housing and the bearing plate is provided with a first labyrinth seal in contact with the screw nut, lubricants leaking out of the rolling bearing is allowed to go to the oil sump via the oil channel and oil-returning hole. The oil slinger thus blocks the lubricants from leaking out of the first labyrinth seal.

摘要： An impeller structure for a centrifugal fan device is disclosed, in which the impeller structure is primarily comprised of: a disc; and a plurality of blade structures, each being arranged on the disc; wherein, each blade structure further comprises: a first blade; and a second blade, arranged at a circumferential length away from a side of the first blade while radially overlapping with the radial of the first blade by a specific overlap area for forming a gap passage functioning as a nozzle. As a fluidic is flowing through and shooting out of the gap passage, not only the growth of the boundary layers on the suction surfaces of front blades are interrupted, but also as the fluidic with high kinetic energy is mixing with the low-kinetic fluidic flowing on the suction surfaces of rear blades, the thickness of the boundary layer is reduced while the separation point is delayed and thus separation can be prevented.
