AI Technical Summary
The air system adjustment of the nozzle tester is done manually, which has a low degree of automation, long test state adjustment time, low test efficiency, and high technical requirements for operators.
An automatic adjustment method is adopted, and the output parameters are calculated by input parameters and mathematical model. The control system directly uses the opening value of the regulating valve as the target parameter for automatic adjustment, simplifies the air system pipeline structure, and introduces total pressure recovery coefficient and flow correction coefficient for real-time correction.
Automatic adjustment of the air system was achieved, reducing adjustment time, saving test costs, and avoiding the problems of coupling and interference between the internal, external, and venting systems.
