Many parameters in the calculation of air-blower test is iterated, so the manual work is tremendous, algorithm function of MATLAB designed the programs which can handle the test data.

This paper is aimed at the breakdown causing the air-blower vibration and gives a brief introduction on the current ways to check the troubles, It also illustrates the feature of each method.

Put burning control switch 3kk hand lever turns right 45 degree to scavenging shelve, contactor 2jlc collects and then air blower works.
