Project description: This project is a set of standard equipment for gas flow of sonic nozzle method constructed by Xuchang Quality and Technical Supervision and Testing Center according to needs.
Home. The whole structure adopts a flat structure design. Compatible pipelines are simple and convenient with a push-pull tube change. Air source uses 2BEA type vacuum pump
The standard device is a sonic nozzle. The air enters the vacuum pump through the front and rear straight pipe sections, the meter clamping device, the stagnation container, the sonic nozzle, and the manifold. use
The microcomputer automatic verification control system can achieve the verification and calibration of the critical flow sonic nozzle junction gas.
