Description

Technical Field

[0001] This utility model relates to the field of compressors, specifically to an automotive centrifugal compressor with adjustable guide vanes. Background Technology

[0002] Centrifugal compressors, also known as scroll compressors, are a type of compressor. Centrifugal compressors are multi-stage and can achieve higher gas pressure, larger processing capacity, and higher efficiency. They are widely used in the chemical industry. Due to seasonal and production adjustment needs, centrifugal compressors sometimes operate in small or large air volume areas that are far from the design point. When the air volume changes, it will cause the performance of the centrifugal compressor to deteriorate, or even cause surge or blockage and shutdown. When the airflow changes, the angle of the guide vanes needs to be changed. However, the existing guide vane structure does not have the function of changing the guide channel in the guide vanes during use, and cannot change the ventilation channel of the guide vanes according to different air volumes.

A transmission ring is connected, and a transmission rod is provided on the outer side of the transmission ring. The top end of the transmission rod extends to the bottom end of the insert. When the knob drives the transmission gear B to rotate, the transmission gear B transmits the power of the knob to the transmission ring, so that the transmission ring, in conjunction with the transmission rod, drives the insert to move inside the guide wheel seat. The adjustment component includes a servo motor, and the output end of the servo motor is fixedly connected to a bevel gear B. One end of the bevel gear B is in contact with the bevel gear A. The bevel gear B and the bevel gear A mesh with each other. When the servo motor drives the bevel gear B to rotate, the bevel gear B transmits the power of the servo motor to the bevel gear A, so that the bevel gear A drives the guide vane to rotate inside the guide wheel seat.

[0005] Furthermore, the inner wall of the compressor body is provided with a mounting hole and a slot on the inner side of the mounting hole. When the guide wheel seat is connected to the compressor body, the guide wheel seat is installed inside the mounting hole, and one end of the plug is inserted into the inner side of the slot.

[0006] Furthermore, a rotating shaft is provided at the center of the guide vane, and the guide vane is rotatably connected to the guide wheel seat through the rotating shaft. The bevel gear A is located at the bottom end of the rotating shaft.

[0007] Furthermore, there are three insert blocks, and the number of transmission rods is the same as the number of insert blocks, with each transmission rod corresponding to one insert block.

[0008] Furthermore, a rack is provided at the bottom of the insert block, and the top of the transmission rod extends to one side of the rack. When the transmission rod rotates, the transmission rod, in conjunction with the rack, drives the insert block to move inside the guide wheel seat.

[0009] Furthermore, both ends of the transmission rod are equipped with transmission gears A, which mesh with the transmission ring and the rack respectively. When the transmission rod rotates, the transmission rod is connected to the transmission ring and the rack through the transmission gears A.

[0010] Furthermore, a control panel is fixedly connected to the outside of the compressor body, and the control panel is electrically connected to both the compressor body and the servo motor.

[0011] The beneficial effects of this utility model are: This automotive centrifugal compressor with adjustable guide vanes allows the insert block to be inserted into the slot by a knob in conjunction with transmission gear B, transmission ring, and transmission rod. This facilitates the fixing of the guide vane seat to the compressor body. Furthermore, a servo motor in conjunction with bevel gears B and A causes bevel gear A to drive the guide vane to rotate inside the guide vane seat, allowing for easy adjustment of the guide vane angle according to different operating conditions.
