English term

jacking

English to Italian Tech/Engineering Mechanics / Mech Engineering Generatori
Nello specifico, il testo che segue è tratto dall'elenco di controllo nel manuale di installazione e messa in funzione di un generatore, ma il termine ricorre anche in altre parti del testo.
Finora avevo tradotto "jacking oil" con "olio di sollevamento", anche se forse sarebbe meglio "olio idraulico" (opinioni in merito sono gradite).
Ora invece mi ritrovo, apparentemente con i sollevamenti (?) dell'albero di sollevamento?? Lo shaft dovrebbe essere l'albero del generatore, a meno che non si tratti di un altro.

Record **jacking** oil pressures on QC sheet
Record **jacking** shaft lifts at each bearing on QC sheet
Inspect **jacking** oil system for leaks
Proposed translations (Italian)
4 +1 olio di sollevamento

http://www.answers.com/Q/What_is_a_steam_turbine_j 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.

olio di sollevamento

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"
