KEPCO Pressure and vacuum system

vacuum conditions be pressurized using a series of centrifugal pumps. Pumping in the Rankine cycle must be both reliable and efficient. The hydraulic analysis reported here examines a part of the pumping cycle, namely for the Feedwater (FW) System, with proposed changes to the equipment which performs this duty.

  • Vacuum sewer - Wikipedia

    A vacuum sewer or pneumatic sewer system is a method of transporting sewage from its source to a sewage treatment plant. It maintains a partial vacuum, with an air pressure below atmospheric pressure inside the pipe network and vacuum station collection vessel. Valves open and reseal automatically when the system is used, so differential pressure can be maintained without expending much energy pumping. A single central vacuum station can collect the wastewater of several thousand individual home

  • Manifold vacuum - Wikipedia

    Manifold vacuum, or engine vacuum in an internal combustion engine is the difference in air pressure between the engineintake manifold and Earthatmosphere. Manifold vacuum is an effect of a pistonmovement on the induction stroke and the choked flow through a throttle in the intake manifold of an engine. It is a measure of the amount of restriction of airflow through the engine, and hence of the unused power capacity in the engine. In some engines, the manifold vacuum is also used as an

  • Vacuum Pressure: What is it how do you measure it?

    It is referred to as pounds per square inch (vacuum) or PSIV. The electrical output of a vacuum pressure transducer is 0 VDC at 0 PSIV (14.7 PSIA) and full scale output (typically 5 VDC) at full scale vacuum, 14.7 (0 PSIA). The vacuum pressure transducer gives an increased positive voltage output proportional to decreasing pressure (increasing vacuum). The absolute pressure transducer gives an increased positive voltage output proportional to increasing pressure (decreasing vacuum). Example
