<p>PURPOSE:To send the optimum amount of airflow to each tank, by providing a valve for controlling an amount of ejected airflow and airflow meter to each of enlarged air-blasting systems and controlling the amount of airflow to each tank system on the basis of said controlling valve and said airflow meter. CONSTITUTION:An amount of airflow to be sucked as output from a sucked airflow detector 13, ejecting pressure as output from a pressure detector 15, an amount of ejected airflow as output from an ejected airflow detector 20, the pressure and the temperature of the atmosphere to be introduced through a main pipe line 11, a temperature at an ejecting side from a block 12 and the coefficient of dynamic resistance equivalent to demand as output from the second arithmetric unit 32 are engaged in the first arithmetic unit 31. The coefficient of dynamic resistance equivalent to demand required for an ejected airflow-controlling valve 21 is calculated and used for controlling the ejected airflow-controlling valve 21. Accordingly, the optimum amount of airflow can be maintained in response to the variation of the condition, and accurate control can be facilitated.</p> |
