Project description: This project is a set of standard equipment for gas flow rate of sonic nozzle method constructed by Dezhou Quality and Technical Supervision Bureau according to need. Complete knot
The structure adopts a tiled structure design. Compatible pipelines use push-pull tube replacement, which is simple and convenient. The air source adopts 2BEA type vacuum pump, and the standard device is
Sonic nozzle. The air enters the vacuum pump through the front and rear straight pipe sections, the clamp device, the stagnation container, the sonic nozzle, and the manifold. Microcomputer automatic detection
Calibration control system to achieve the verification and calibration of critical flow sonic nozzle junction gas.
