Gas Compressor Principles Quiz Welcome to your Gas Compressor Principles QuizWhat is Stonewall? When the compressor runs at maximum speed When the compressor runs at maximum flow When the compressor runs at minimum speed When the compressor runs at minimum flow None 2. The function of the impeller is to Increase the velocity of the gas Increase the pressure of the gas Decrease the velocity of the gas Direct the flow of the gas None 3. The function of the balance piston is to Improve the balance of the rotor Relieve the gas pressure to prevent over-pressurization Counteract the aerodynamic thrust of the rotor Seal the gas from the lube oil None 4. Seal Gas is typically supplied from; Compressor discharge after the unit comes on line Compressor suction after the unit comes on line Leakage across the internal labyrinths External nitrogen source None Time's up
