[0093] The actual water flow and theoretical water flow of each circuit can be viewed through the secondary cooling circuit working status monitoring page. The deviation between the two is presented in the form of a bar graph. If the actual water flow is higher than the theoretical water flow, the bar graph of this circuit is above the baseline; if the actual water flow is lower than the theoretical water flow, the bar graph of this circuit is below the baseline. From this, the size of the actual water flow deviation of each circuit can be intuitively seen, and different degrees of deviation are represented by different colors. From this, the instantaneous working status of the nozzle includes: blockage, slight blockage, normal, slight leakage and leakage. Users can use this to judge whether the status of the nozzle on site is normal. At the same time, double-click a circuit to view its historical working status.
