Description

Technical Field

[0001] The invention relates to the technical field of fan manufacturing, and in particular to a fan circular runout and height automatic detection device. Background Art

[0002] A centrifugal fan draws air into the blade space from the axial direction of the fan. Then, driven by the impeller, the airflow rotates with the impeller on the one hand; on the other hand, the impeller is lifted up by inertia, and finally the airflow leaves the impeller in the radial direction. It is a fan that relies on centrifugal force to do work. In the manufacture of centrifugal fans, in order to ensure the reliability of the installation and the stability of the rotation of the centrifugal fan impeller and to reduce the noise generated by the rotation of the impeller, it is necessary to measure the height of the assembled impeller and the circular runout during the rotation of the impeller. At present, the equipment for measuring the impeller of a fan can only measure a single radial runout, axial runout or installation height, and the measurement process requires manual assistance. The detection efficiency is low and the information obtained from the detection cannot be effectively recorded. In order to improve the quality of the installed fan and the accuracy of the detection, a fully automatic impeller detection equipment with multiple parameter detection is required.
