GAS DENSITY CONTROLLING APPARATUS FOR PREVENTING NO-LOAD OPERATION OF BOOSTER CAPABLE OF IMPROVING BOOSTING PERFORMANCE

摘要

PURPOSE: A gas density controlling apparatus for preventing no-load operation of a booster capable of improving boosting performance is provided to prevent the deterioration of boosting performance by boosting and outputting a density-controlled mixture gas in a booster. CONSTITUTION: A switch(21) is switched to a manual mode by an operator or to an automatic mode by a controller. A gas density measuring sensor(23) is connected to the switch and measures density of a gas passing through a feeding pipe line. A gas density controller(100) is composed of a PID(Proportional Integrate Derivative) controller(24) to control the feeding amount of a control gas for controlling pressure of the gas passing through the feeding pipe line. An injector(200) is connected to the gas density controller and composed of an injection nozzle(210) having a screw groove(211).
