Lube Oil Pump Power For Emergency

The Galbraith-Pilot Marine Division of Marine Electric RPD, Inc., 166 National Road, Edison, N.J., has introduced a lube Oil Pump Emergency Power Source to assure protection of ship propulsion machinery after a'power interruption.

The emergency power source is an "uninterruptible" power system which goes on immediately after a power interruption, thus assuring a constant flow of lubrication oil for at least 10 minutes, during which time normal power can be restored.

In the past, most shipboard emergency lube oil pumping systems have relied on stored air pressure tanks to drive a pneumatically powered pump for the "wind down" period. However, the need for reliability and repeatability (air pressure tanks must be replaced or repressurized) has given e m e r g e n c e to stored electrical power as a better approach.

The unit consists of a battery, battery charger and a reduced voltage motor controller assembled in a single metal enclosure suitable for deck mounting. The enclosure is steel construction suitably braced to provide a freestanding structure with mounting angle for bolting. Two compartments are c o m p l e t e l y isolated from each other, one compartment for housing the battery and the other compartment for housing the battery charger and the reduced voltage motor controller. The Galbraith-Pilot Lube Oil Pump Emergency Power Source is fully rejuvenated within eight hours after main a-c power is restored. A battery charger maintains the 120-v d-c battery pack at full charge, ready to deliver a full 39 amps for up to 10 minutes to the d-c pump motor, 5 hp, 900 rpm.
