YDRAULIC PUMP ASSEMBLY
Hydraulic fluid heaters in the oil reservoir will warm the
fluid up to 70°F ±5 degrees before use of the GSI
The hydraulic pump assembly (fig. 12-12) is located
as close as possible to the stabilized platform. It
provides hydraulic fluid at 1,400 psi to the hydraulic
actuator on the stabilized platform. `he motor and
controller operate on 440-V three phase received from
the ship's normal power supply. The temperature
switches (not shown) operate the HIGH TEMP light on
possible to the stabilized platform. Its purpose is to step
the remote control panel. Also, a pressure switch in the
down the voltage for the source light (GSI) from 0- to
hydraulic pump discharge line will close at 1,200 psi. If
115- volts ac to 0- to 18.5-volts ac depending on the
not closed, the pressure switch will de-energize the
electronic panel assembly on low oil pressure.
