Put 12 driving rotating speed, the timer 17 makes the flabellum in default test to set the driving time of the drive device 12
Time operates, and wherein the driving time is according to the specification of each flabellum, such as the size of flabellum and the use occasion of flabellum
Depending on.
In addition, linking the force (forcing) pump 14, the pressure-sensing provided with a pressure sensor 19 in the chamber 111 of the casing 11
Device 19 senses the Fluid pressure in the chamber 111, and the compression pump 14 is according to the sensing adjustment of the pressure sensor 19 to fluid
Pressurize to ensure that the fluid in chamber 111 reaches predetermined fluid pressure.
It is the utility model method of testing flow chart please continue to refer to Fig. 3.Refer to Fig. 1, this practicality in the lump as shown in this figure
Flabellum is placed in the test system as described in figure 1 above and tested by new method of testing, including step is as follows：
Step 1 (SP1)：One flabellum is arranged in a chamber of a casing, and the flabellum is linked a drive device
One drive link.In this step, flabellum 15 (such as axial flow fan leaf or centrifugal flabellum) is placed in the chamber 111 of casing 11, and
Combined with the drive link 121 of drive device 12, flabellum 15 can be screw lock or clamping with the combination between drive link 121
Or snapping.
Step 2 (SP2)：A fluid is provided by a fluid source to flow after a force (forcing) pump is pressurized to a predetermined fluid pressure
Enter in the casing.In this step, open fluid source and pass the fluid through the inflow force (forcing) pump 14 of piping 18, then pass through from force (forcing) pump 14
Pipeline 18 flows into chamber 111,14 pairs of fluid pressurizations of force (forcing) pump so that the fluid flowed into chamber 111 is pressurized to one and preset
Fluid pressure, and by the Fluid pressure of pressure sensor 19 in the chamber 111, the compression pump 14 is according to the pressure sensor
Pressurization of the 19 sensing adjustment to fluid, to ensure that the fluid in chamber 111 reaches predetermined fluid pressure.
Step 3 (SP3)：The drive device drive the flabellum with a desired speed the predetermined fluid pressure fluid transfer
It is dynamic, and shut down after a default rotation time.In this step, when the fluid for flowing into chamber 111 flooded the flabellum 15 or
After whole chamber 111, stopping injects fluid into chamber 111, starts the drive device 12 and drives the flabellum 15 default
Rotated in the fluid of Fluid pressure, wherein the drive device 12 can drive rotating speed via the tacho 16 regulation, and via meter
When device 17 setting driving time so that the flabellum in the default testing time with a predetermined rotation speed operation.
The utility model through the above step 1 to step 3 to make flabellum operate in the fluid with pressure, with test
The intensity of the fluid resistant pressure of flabellum 15, for example, flabellum 15 is placed in the chamber 111 of casing 11, fluid is pressurized to
5Kg, drive device 12 drives the flabellum 15 persistently to be rotated in 5Kg Fluid pressure 1 hour with 5000r.p.m. rotating speed, with
Test the intensity of the fluid resistant pressure of the flabellum 15.
It is another method of testing flow chart of the utility model please continue to refer to Fig. 4, Ben Tu and Fig. 3 difference are to further include
Step 4 (SP4) is behind the step 3 (SP3), the step 4 (SP4)：According to the external form and task performance of the flabellum and work
The change of abnormal sound wherein at least one judges the intensity of the fluid resistant pressure of the flabellum.In this step by foregoing by tolerance stream
The flabellum 15 of the body intensity of pressure takes out from the chamber 111 of casing 11, then according to the external form and/or task performance of flabellum and/or
The change of work abnormal sound judges the tolerance intensity of flabellum 15.
Foregoing flabellum external form refers to whether flabellum deforms or be broken, and whether flabellum, which deforms, can utilize the measurement of contact
(such as measuring head) or contactless measurement (for example scan measurement instrument with 3D lasers and carry out 3D non-contact optical measurements), thoroughly
Cross axial deformation and radial deformation numerical value that these measure flabellum.
Aforementioned operation efficiency refers to flabellum being put into wind tunnel tester measurement blast-generator volume curve (P-Q curve maps), wind
Amount refers to flabellum " total volume of air of submitting or suction per minute ".Air quantity unit is CFM, as cubic foot per minute
(Cubic Feet per Minute)；If calculated by stere, for CMM (Cubic Meters per Minute).
The blast of fan is also known as static pressure (static pressure), refers to fan in inlet end and the air pressure difference at blowout end, generally makes
It is that millimeter water column height (mmH2O) or inches of water(in H2O) are high (inchH2O) with unit.
Foregoing abnormal sound, which refers to flabellum being put into anechoic chamber, to be measured, it is however generally that the noise of anechoic chamber is less than
17dB。
For example, the foregoing rotating speed with 5000r.p.m. is persistently rotated to the flabellum of 1 hour in 5Kg Fluid pressure
Whether 15 take out from casing, be then broken according to the flabellum 15, judge the flabellum 15 not over test if fracture.Again
Whether person, the axial deformation that the flabellum 15 is measured if the flabellum 15 is not broken is less than or equal to 0.1mm；Whether radial deformation
Less than 0.2mm, and whether blast is less than or equal to 12mm water columns；Whether air quantity is less than or equal to 5CFM；Whether abnormal sound is less than or equal to 33
Decibel judges the flabellum 15 is whether there is by test.The numerical value of projects is not limited to the utility model in example, can basis
The demand setting of tester.
System and method more than is to make flabellum 15 be operated in a fluid with pressure, to test the flabellum 15
The fluid resistant intensity of pressure, and the external form and task performance of the flabellum 15 of test of the detection Jing Guo the fluid resistant intensity of pressure and
Whether the change of work abnormal sound wherein at least one judges the intensity of the fluid resistant pressure of the flabellum 15 by test.
Only as described above, is only the preferably feasible embodiment of the utility model, the utility model is utilized such as
Above-mentioned method, shape, construction, device change for it, should all be contained in the interest field of this case.
