1 When working with pumps, technicians should make sure water is collecting under the oil.
2 Interlock systems are used to bypass emergency shutdown systems in order to keep production running so a particular unit can meet its production goals.
3 Compressors move liquids, and pumps move gases.
4 When a dynamic compressor is backed up to its surge point on the compressor’s performance curve it may stall.
5 Gas and steam turbines are activated by the expansion of fluid on a series of curved rotor vanes attached to a central shaft.
1 False. When working with pumps, technicians should make sure that water is not collecting under the oil because it can cause bearing failure.
2 False. These interlock systems are designed to shut the compressor down if high vibration or excessive shaft movement is detected.
3 False. Compressors move gases, and pumps move liquids.
4 True.
5 False. A gas turbine is a device that uses the combustion of natural gas to spin the turbine rotor. A steam turbine is a device that is driven by the pressure of high-velocity steam discharged against the turbine’s rotor.
