for GenSet Applications Technical Data Rating Definition Gen Set Continuous Power This type of rating applies to heavy-duty diesel generator sets when used as a utility power source. The engine is expected to be operated with constant and/or dedicated loads with load factors up to 100% of the continuous power rating. Under these conditions, the engine may be operated for an unlimited number of hours per year. Gen Set Limited Running Time Power This type of rating applies to heavy-duty diesel generator sets when used as a utility power source which will deliver rated power for up to 700 hours per year. Normal varying load factors and/or constant dedicated loads must not exceed 75% of the limited running time power rating. Gen Set Prime Power This type of rating applies to heavy-duty diesel generator sets when used as a utility power source. It is subject to normal varying load conditions, with an intermittent overload capability of 10% (up to the standby power rating), for no more than

Although the hydraulic systems used aboard vary widely. They may, however, be grouped into the three basic set ups. Constant flow For a constant flow pump it is possible to vary the flow to a load by varying the outlet from the load. The major components are the fixed delivery pump, unloading valve, and accumulator. The accumulator consists of a steel pressure vessel within which is a rubber bag. The space between the bag and the steel walls is filled with nitrogen at a set pressure. When the constant delivery pump is started, oil is supplied to the accumulator inflating the bag with oil against the nitrogen pressure. When the set system pressure is reached the unloader valve will open maintaining system pressure at a set amount. The check valve maintains the pressure in the accumulator giving a ready reserve on demand. An alternative to this is to have a pressure cut out switch for the pump with a suitable dead band to prevent cycling. When a throttle or control valve
