Turbofan is qualified, and otherwise the turbofan is unqualified.That is, pressure-time curve and flow-time curve, its
As long as in have one beyond default scope, it is either bigger than preset range or smaller than preset range, be all judged to not conforming to
Lattice.So, it may not be necessary to which turbofan is attached on whole machine, going experiment, whether it is qualified, so as to improve the matter of machine product
Amount and qualification rate.As shown in Figure 3 and Figure 4, it is a kind of pressure-time curve of embodiment collection of this patent, current-time song
Line, wherein, bold portion is that the pressure that gathers and the pressure of flow signal formation, flow are bent in turbofan start-up course in figure
Line, dotted portion is pressure-time curve and the default scope of flow-time curve, and the curve ranges can pass through collection
Pressure and data on flows when substantial amounts of qualified turbofan normally starts, take in the scope of minimum and maximum value formation, such as figure
The scope of dotted line formation, as shown in Figure 3 and Figure 4, wherein within a preset range, and flow-time curve has pressure-time curve
Part exceeds preset range, therefore the turbofan detected is unqualified.
It is preferred that, in the step S01, by turbofan rapidly start and stop at least three times.So by repeatedly rapidly opening
Stop turbofan, if turbofan, which exists, does not install firm impeller or other problemses, ensure firm impeller meeting is not installed
Break down, the accuracy and reliability of detection can be improved.
It is preferred that, in the step S01, the detailed process by turbofan rapidly start and stop is, by whirlpool in 1.5s-3s
The rotating speed of wheel blower fan accelerates to maximum (top) speed, and then turbofan stops operating in 0.5s-1.5s.It is of course also possible to root
It is adjusted according to different turbofans.
It is preferred that, in the step S02, the detailed process of normal startup turbofan is, by turbine in 3.5s-5s
The rotating speed of blower fan accelerates to maximum (top) speed.It is of course also possible to be adjusted according to different turbofans.
It is preferred that, the maximum (top) speed is 30000-35000 revs/min.
It is preferred that, in the step S03, normal boot process is gathered especially by pressure sensor and flow sensor
The pressure and flow signal of middle turbofan, and by the pressure and flow signal instantaneous transmission to host computer, formed pressure-when
Half interval contour and flow-time curve.So, pressure sensor and flow sensor can pass through pressure acquisition pipe and flow respectively
Collection tube, connects the pressure and flow signal in the outlet pipe of turbofan, collection turbofan normal boot process, and will
Pressure and the flow signal instantaneous transmission is carried out after signal transacting to host computer, formed pressure-time curve and flow-when
Half interval contour.Pressure and flow signal are gathered by pressure acquisition pipe and flow collection pipe, the precision of signal acquisition can be improved, entered
And improve the accuracy of detection.
The above is only preferred embodiment of the present utility model, it is noted that for the common skill of the art
