解釋
超額定速度試驗-
Overspeed test for industrial fan impeller
工業通風機葉輪超速試驗 -
This paper starts with resolving reliability of steam sets, then illuminates the problem and design principle of oil test device of overspeed protection system, which is made by shanghai turbine company ltd.
=本文從提高機組可靠性的問題入手，探討了上海汽輪機廠所產超速保護系統注油試驗裝置存在的問題及改進原理。 -
So we ca n ' t do oil filler test when the units in operating to test the reliability of overspeed protection system. firstly, this thesis presented the theory of overspeed protection system. and pointed out the reason why the emergency stop system is often fails in stroke
本文首先分析了該型超速保護的動作原理，指出該型危急保安器注油試驗拒動的原因；首次利用流體力學的相關理論引入射流的概念，提出了改造方案，同時對該型危急保安器注油試驗裝置改造后飛環提前動作作出了理論分析。 -
As we know, overspeed protection system is one of main protection of steam turbine sets. base on the standing order, we must do oil filler test regularly, but the oil filler test of the emergency stop system, which made by shanghai turbine company ltd., is often fails in stroke
超速保護系統是汽機主要保護之一，根據規程規定，要定期進行注油試驗以驗證超速保護的可靠性，但上海汽輪機廠所產的危急遮斷器在注油試驗中經常拒動，導致在運行中無法進行注油試驗，無法驗證超速保護系統的可靠性。 -
The effect of oil filler test that is improved is correspondence to the overspeed test, so it is no use to do overspeed test repeatedly. it can reduces the deterioration of the rotor ' s longevity, and that, it can reduce the starting time of the units, which can reduce the cost of fuel consumption and steam deterioration. especially to large capacity steam units that use the same style device, it will get large economic effectiveness
對使用同一原理的裝置而言，這種新的技術思路具有指導性意義，改進后的注油試驗使用起來的效果可以與超速試驗相對應，不需要重復做超速試驗，可以減少對因超速對轉子的壽命的損耗，並且還縮短了試驗所需要的時間，相應減少機組的啟動耗時，節約燃料成本及汽水損耗，尤其是對使用同類裝置的大容量機組而言，能夠獲得的經濟效益將是巨大的。
