Abstract

The invention discloses a mounting jig for a wind tunnel ejector. The mounting jig comprises a tool plate welded to a ejector tunnel body, and a positioning ring fixed to the too plate, wherein the tool plate is provided with a plurality of matching holes used for mounting the positioning ring; the positioning ring is fixed to the tool plate through bolts; a gas collection chamber of the ejector tunnel body is provided with a mounting hole used for mounting a nozzle assembly bent end; and the positioning ring is provided with a limiting ring used for clamping the nozzle assembly nozzle end. According to the mounting jig for the wind tunnel ejector, the mounting precision of a nozzle assembly is ensured, and meanwhile, the mounting efficiency of the mounting jig is improved.

Description

technical field [0001] The invention relates to the technical field of wind tunnel ejector installation, in particular to an installation jig for a wind tunnel ejector and a nozzle installation method thereof. Background technique [0002] The wind tunnel ejector is a fluid delivery device widely used in ultra-high-speed wind tunnels. It relies on the high-speed flow formed after the high-pressure fluid flows through the nozzle to eject another low-pressure fluid, and performs energy exchange and material mixing. Mix, and finally achieve the purpose of transportation. The nozzle assembly is the key core component of the ejector. As the driving device of the ejector wind tunnel, its installation accuracy will directly affect the effect of the ejector in the wind tunnel. [0003] The existing method is to fix the nozzle assembly by temporary support when installing it. However, in this way, it is difficult to meet the design requirements for the cross-section formed by multip...
