摘要： A system includes a dynamic compressor and a controller. The dynamic compressor includes a motor having a driveshaft rotatably supported within the dynamic compressor and a compression mechanism connected to the driveshaft and operable to compress a working fluid upon rotation of the driveshaft. The controller is connected to the motor and includes a processor and a memory. The memory stores instructions that program the processor to operate the motor to compress the working fluid at a motor speed greater than a predicted minimum surge speed plus a control margin, determine when surge events have occurred, store, in the memory, an indication of each surge event that the processor determined to have occurred, and determine whether or not to take a protective action when the processor determines that a surge event has occurred.

摘要： A manual-adjustment-type device for adjusting the swing angle of an electric fan according to identifications, the device comprising an identification disc, an angle adjustment knob and a sliding slot-sliding block crank adjustment mechanism. A limiting slot-limiting block mechanism is arranged between the identification disc and the angle adjustment knob; an inner wall of a second inner cavity of the sliding block is provided with a rack, an outer wall of the sliding block is provided with graded recessed and protruding bodies, and the center distance between the graded recessed and protruding bodies is equal to the pitch of the rack; a first limiting sliding slot is provided with a notch, and a spring-setter device is arranged at the notch and is in elastic setting contact with the graded recessed and protruding bodies; the lower end face of the sliding block is provided with an overlapped protruding block, and the overlapped protruding block is arranged in an extending sliding slot arranged at an edge of a second limiting sliding slot of a limiting cover, so as to form a sliding fit therebetween; and an inverted protruding block-through hole snap-fitting contact combined structure is arranged between the angle adjustment knob and a bidirectional connection block. Thus the manual-adjustment-type device for adjusting the swing angle of an electric fan according to identifications is formed; and by means of the device, gear damage can be avoided, the angle can be adjusted accurately and equally according to identifications of the identification disc, and the angle adjustment knob is prevented from becoming loose and falling off.

摘要： A ceiling fan and a structure thereof are provided. The structure includes a blade holder, a plurality of blades, and a plurality of positioning elements. The blade holder includes a holder body and a plurality of support platforms. The holder body has a plurality of first matching structures spaced apart from each other. Each of the support platforms includes a first positioning structure. Each of the blades has a second matching structure and a second positioning structure. The second matching structures can be guided by the first matching structures, so that each of the blades is disposed at an installation position on one of the support platforms along an oblique track. When each of the blades is located at the installation position, the first positioning structures and the second positioning structures abut against each other.
