各位大虾：
主机降速的设置点是多少？
大家帮忙判断一下，若主机的设计点L1为9480Kw X 127rpm，SMCR点为8000Kw X 120.1rpm。
以下是操纵说明书里的：
The values stated in the list on the following pages refer to layout point L1.
(Nominal max. continuous rating).
The values must only be used as a guidance in connection with the ‘List of Capacities
of Auxiliary Machinery’ for dimensioning of auxiliary systems, and must not be
used for determining the extent of the alarms or actions.
The item numbers refer to the drawings showing the extent and placement of sensors
for standard alarms and indicators on the engine, if the signal equipment is
fitted. See Section 701-03, furtheron.
For sensors placed in the systems outside the engine, see the actual pipe arrangements
in the appropriate chapters.
If the engine is provided with special equipment, some values may differ from this
list. The correct values shall in such a case be obtained from the Plant Installation
Drawings.
The engine slow-down level corresponds to 40% of nominal MCR r/min.
Engines specified and optimised at derated power may have other normal service
values depending on layout power/revolutions and application.
For derated engines, the testbed/trial values should be used. |
