Fan temperature rise test system described in the utility model, wherein, static pressure regulator can be a venetian blind, is connected with the adjusting motor of a can regulate venetian blind blinds rotation angle on the bellows outer wall, regulates motor and is electrically connected with computer.
Fan temperature rise test system described in the utility model wherein, can be connected with on the bellows outer wall blower fan to be measured is installed the locking pliers that compresses fast, and locking pliers is positioned at the intake grill place and circumferentially evenly distributes along intake grill.
Fan temperature rise test system described in the utility model, wherein, blower fan to be measured is connected on the wind-guiding panel by screw, and the wind-guiding panel is connected on the installation panel by screw, and installation panel is contained in the intake grill place, and locking pliers is pressed on the installation panel.
Fan temperature rise test system described in the utility model, wherein, static pressure transducer is connected on the support by screw, and support is connected on the bellows inner chamber diapire by screw.
After adopting above structure, compared with prior art, the utility model fan temperature rise test system has the following advantages: because the utility model fan temperature rise test system can be simulated the actual environment static pressure of client when using blower fan by bellows and static pressure regulator, in other words, after putting into blower fan to be measured in the bellows, the residing environment static pressure of blower fan to be measured is identical with client's residing environment static pressure of blower fan when reality is used, therefore, the utility model fan temperature rise test system can record client's temperature rise that blower fan produced in actual use before blower fan dispatches from the factory, thereby has effectively guaranteed the temperature rise precision of test result.
Adopt frequency conversion fan to compare with the routine techniques static pressure regulator, the utility model fan temperature rise test system adopts venetian blind to regulate bellows inner chamber static pressure and can reduce production costs greatly.
The setting of locking pliers can make the installation of blower fan to be measured become simple more, convenient.
