Fan impeller balance calibrating method

Abstract

A fan impeller balance calibrating method includes steps of: placing a fan impeller onto a measurement platform, the measurement platform having a controller, a speedometer device and a detection device being arranged on the measurement platform for detecting the rotational speed and balance of the fan impeller respectively, the controller receiving data from the speedometer device and the detection device to calculate and generate a detection signal to the measurement platform, according to the received detection signal, the measurement platform displaying calibration data and rotational speed data; and adding at least one weight body to the fan impeller or removing at least one weight body from the fan impeller according to the calibration data to quickly calibrate the balance of the fan impeller. The fan impeller balance calibrating method is advantageous in that the balance calibration time is shortened and the calibration process is simplified.

What is claimed is: 
     
         1 . A fan impeller balance calibrating method comprising steps of:
 placing a fan impeller onto a measurement platform, the measurement platform having a controller, a speedometer device and a detection device being arranged on the measurement platform for detecting the rotational speed and balance of the fan impeller respectively, the controller receiving data from the speedometer device and the detection device to calculate and generate a detection signal to the measurement platform, according to the received detection signal, the measurement platform displaying calibration data and rotational speed data; and   adding at least one weight body to the fan impeller or removing at least one weight body from the fan impeller according to the calibration data to quickly calibrate the balance of the fan impeller.   
     
     
         2 . The fan impeller balance calibrating method as claimed in  claim 1 , wherein the detection device employs a flashlight to judge the unbalanced angle of the fan impeller. 
     
     
         3 . The fan impeller balance calibrating method as claimed in  claim 1 , wherein the detection signal contains the calibration data and the rotational speed data. 
     
     
         4 . The fan impeller balance calibrating method as claimed in  claim 1 , wherein the weight bodies are coupled with the fan impeller according to the numeral of the calibration data displayed by the measurement platform. 
     
     
         5 . The fan impeller balance calibrating method as claimed in  claim 1 , wherein the weight bodies have different weight values. 
     
     
         6 . The fan impeller balance calibrating method as claimed in  claim 1 , wherein in the case that the numeral of the calibration data is higher than a preset balance value of the fan impeller, then the weight value of the weight bodies is reduced. 
     
     
         7 . The fan impeller balance calibrating method as claimed in  claim 1 , wherein in the case that the numeral of the calibration data is lower than a preset balance value of the fan impeller, then the weight value of the weight bodies is increased. 
     
     
         8 . The fan impeller balance calibrating method as claimed in  claim 1 , wherein the weight bodies are made of hardened plastic material and detachably adhered to an inner side of the fan impeller.
