[0002] An impeller is a rotating component commonly used in equipment such as pumps, fans, compressors, and turbines. Its function is to convert energy into kinetic energy of a fluid or gas, thereby generating fluid or gas flow. An impeller generally consists of multiple blades, the shape and arrangement of which can be designed to meet specific application requirements.

[0003] Measuring the impeller through-hole diameter can ensure the installation compatibility between the impeller and the shaft. If the through-hole diameter does not match the shaft diameter, it may cause installation difficulties, loose connections, or the gap between the shaft and impeller is too large or too small, affecting the operating stability and performance of the equipment.

During measurement, the impeller is prone to slip, resulting in a large measurement error, which affects the measurement accuracy. Therefore, an impeller size detection tool is proposed to solve the above problem. Utility Model Content
