The situation of change of rotating shaft torque when high low speed switches, and then to set suitable time interval to provide data reference.
Under normal conditions, the real-time torque of blower fan be can not be measured directly, be merely able to the performance by the blower fan that converts
Measurement data (total head, flow, static pressure, rotating speed etc.) so as to obtaining its power output in a certain stable operating point and turn indirectly
Square.Because the performance test time of blower fan is long and must carry out under stationary conditions, also simply exist even if the torque being calculated
Average value in certain time, therefore can not be realized at all by this method in the case where changing operating mode to the real-time of blower fan actual torque
Accurate measurement.
