olio di sollevamento Explanation: credo che qui intenda sempre "jacking oil shat lifts" ovvero "il sollevamento dell'albero su ogni cuscinetto causata dall'olio (ad alta pressione). Quindi tradurrei semplicemente: "Registra i sollevamenti dell'albero su ogni cuscinetto" |

Reference: http://www.answers.com/Q/What_is_a_steam_turbine_jacking_oil_system Reference information: At the time of turbine start up, the shaft journals are in contact with the white metal of the bearings due to the weight of the rotor. The low pressure of the lubricating oil supply when the set is stationary is insufficient to stop the metal to metal contact between journals and bearing shells. In order to prevent the metal to metal contact journals and bearing shells during start up, which is damaging in the long term, an oil pocket machined into the bottom shell of the journal bearing is supplied with oil under high pressure This lifts the shafting system slightly and il floats on a film. This is called “jacking” oil system of turbine. |
