Abstract
The invention relates to a combinational fan composite failure diagnosis test method, which belongs to the field of the failure diagnosis method. The method comprises the following steps of (1) acquiring the data information of a fan under a normal operation state; (2) normalizing the collected data information to form a variation space of the data information; (3) analyzing the data information of the fan in failure, and estimating a fan failure space; and (4) by simulating the rotation situation of the fan through a combinational composite test rotary machine, simulating the data information of the fan in failure so as to find out a failure reason. The method has the beneficial effects that 1, the operation data of the fan can be stored and normalized, the failure of the fan can be found out by utilizing the combinational composite test rotary machine to simulate the real operation state of the fan according to the real operation situation of the fan, and the failure can be rapidly found and rapidly solved; and 2, when the fan is repaired, the manpower and the labor resource can be saved.
