coast down period
Thread Content
The tank shall have enough capacity to cover the coast-down period. This capacity shall be determined by the Vendor. What exactly is the coast-down period? Can it be referred to as the inertia (decline) period? :L Last edited by lihx_susan on 2008-9-4 11:31 ]
It’s the time up to arrival; it seems that this tank is required to maintain its storage capacity or other functional properties during that period.
Coastdown: A process that allows the reactor’s power level to decrease gradually as the fuel in the core is used up. Therefore, the owner’s question can be translated as “the load-reduction phase”; this tank is likely used for storing the fuel when the plant is shut down.
A drop in the coast level indicates a period of material shortage, a short supply period
When posting on LZ, it’s necessary to indicate the industry involved, so as to reduce the time needed for others to guess. In your sentence, does “Tank” refer to the fuel tank of a car or some other type of storage tank? If it is a car, it is recommended to translate it as gliding ； In the power generation industry, in addition to steady state, generator sets also experience transient processes such as start-up, coast down, or load changes.
I assume it means that the high-level oil tank of the compressor must have sufficient capacity, so that it can supply oil to the compressor after an emergency shutdown until the unit comes to a complete stop.
I understand that it is also the case that after a failure of the lubricating oil pump in the compressor’s overhead tank, the oil in that tank is used to lubricate and cool the unit until it stops operating.
Idling period: The idling time is the interval from when the turbine is shut down to when the turning speed of the rotor reaches a certain level. The capacity of the high-level oil tank must be sufficient to meet the requirements during this idling period, and this capacity is determined by the supplier!
The tank must have sufficient capacity to cover the coast-down period. This capacity shall be determined by the Vendor. In any case, this tank is a sealed tank among the moving equipment; it has enough volume to compensate for the drop in the liquid level of this sealed tank when the equipment starts operating.
