Critical breaker impactor fuel injection test
Thread Content
Gentlemen! Is the critical trip striker injection test conducted while the unit is running or when it is stopped?
Generally, first a test is conducted in a static state to check whether the emergency shutdown valve operates smoothly; during single-unit testing, tests on the emergency safety system can be carried out.
I haven’t done the experiment you mentioned. . . Could you explain it in detail?
Test in a rotating state. Generally, a dynamic test is carried out while driving; if it works, the circuit breaker is reset and the speed control valve is opened, after which driving can continue ； During operation, perform fly hammer fuel injection tests regularly: move the handle to the test position, open the test fuel valve; if the fly hammer moves, it indicates that the circuit breaker is functioning properly. Drain the test fuel, reset the fly hammer, then move the handle back to the operating position to continue operation, thus completing the fly hammer fuel injection test.
