Description

Technical Field

[0001] The utility model relates to the technical field of diffusers, in particular to a diffuser with adjustable blades. Background Art

[0002] The diffuser with adjustable blades is a key component in centrifugal compressors. It is mainly used to optimize the flow characteristics of the airflow and improve the compression efficiency. By adjusting the installation angle of the blades, this diffuser can improve aerodynamic performance, reduce flow losses, and adapt to different working conditions. The blade adjustment function enables the compressor to operate under variable conditions, expands its stable operating range, and helps maintain the stability of the production system. In addition, the diffuser with adjustable blades further improves the smoothness of gas flow and compression efficiency by reducing flow separation and shock waves. In energy storage systems, the use of such diffusers is particularly important because they have a significant impact on the overall efficiency and economy of the system. Recent technological advances, including the use of 3D printing additive manufacturing methods, have made the design and manufacture of diffusers more efficient and precise, which will help further improve the performance of centrifugal compressors.

[0003] After searching, the patent number "CN213574832U" mentioned in the text that "the utility model discloses a diffuser for a centrifugal compressor with adjustable blades, which relates to the technical field of diffusers. The utility model includes a mounting plate, a rotating column is fixed on the upper side of the mounting plate, a telescopic pull rod is arranged on the circumference of the rotating column, and a fan blade is installed on one end of the telescopic pull rod; a limiting groove is arranged inside the telescopic pull rod, and a baffle is slidably matched inside the telescopic pull rod, one side of the baffle is fixedly connected with a sliding rod, and a spring is also installed on one side of the baffle. The utility model uses a rotating shaft installed between the two support plates to facilitate the fan blades and the fixed plate to rotate and rise with the telescopic pull rod under the action of centrifugal force during the rotation of the device, and can fall through the rotating shaft when not in use and stick to one side of the rotating column, thereby reducing the placement space of the device and facilitating the rapid generation of diffusion when the device is in use. When the fan blades are in a centrifugal state, the baffle in the telescopic rod can squeeze the spring to make the telescopic rod retract and retract. When in use, through the rotating shaft installed between the two supporting plates, the fan blades and the fixed plate can be rotated and raised with the telescopic rod under the action of centrifugal force during the rotation of the device, and can fall through the rotating shaft when not in use and stick to one side of the rotating column, thereby reducing the placement space of the device and facilitating the rapid generation of the pressure diffusion effect when the device is in use.
