| 成果简介 | NOVELTY - The rig has a housing (1) with a channel, an air flow supply unit designed with a possibility of pumping an air flow through the channel, and an air flow speed control unit (10) designed with a possibility of changing air flow speed from 0 to 21 m/s. The housing is equipped with a unit for fastening a fire detector. The channel has a constant cross-section along length or a variable cross-section along length. The channel is designed with possibility of changing cross-section along length. The channel is made in form of a Laval nozzle, and an insert (7) is placed in the channel. The insert is designed with ability to change spatial position in the channel and be removed from the channel. USE - Test rig for testing resistance to air flow of fire detector. ADVANTAGE - The test rig can ensure a high-speed air flow directed at a fire alarm during testing for resistance to air flows. DESCRIPTION OF DRAWING(S) - The drawing shows the schematic view of the stand with the detached wall to which one insert is placed in the channel and the air flow speed control unit contains the regulator. 1Housing 3Wall 7Insert 10Air flow speed control unit 17Viewing window |
