When the set pressure can not be maintained even if the rotating speed is continuously increased, the system judges that the pipe explosion fault occurs. However, because the frequency converter and the motor belong to open-loop control, the rotating speed read by the system from the frequency converter is not the actual rotating speed of the motor, but is calculated by the linear ratio of the frequency to the rotating speed, so that the real reliability of the rotating speed of the motor cannot be ensured, and the reliability of the system algorithm cannot be ensured.
