Medium-sized turbine

How pressure of oil is managed when starting or stopping the medium-sized turbine?

E

Expert

Verified

An auxiliary pump is offered in order to maintain the oil pressure. Some of the auxiliary pumps are turned by the hand crank; others are motor-driven. This pump is used whenever the integral pump is running too slowly in order to provide the pressure, as when the starting or securing the medium-sized turbine.
