According to the operation of subcritical reheat controlled circulation drum boiler, this paper analyses the factors which affect the responding speed to unit load, through modifying the coordinating control system, fully using the boiler ability of heat accumulation and other methods, the author puts forward some measures to raise responding speed to unit load
分析了影響中間儲倉式汽包爐機組快速響應電網負荷變化的因素，通過對協調控制系統的改進，以及充分利用鍋爐蓄熱能力等方法，提出了提高機組快速響應負荷變化的幾條途徑。 -
Through developing the comprehensive experiment device with large - scale drum strength and stability, the stress - measuring experiments of various wall thickness of the normal drums of the cranes were performed. the law that the stress of the drums along the circumference and along the axis changes with the load increase of the wire ropes was studies for the first time
通過研製全比尺大型捲筒強度、穩定性綜合試驗裝置，對起重機常用規格的捲筒進行了各種壁厚條件下的應力測量試驗，首次對捲筒體周向和軸向應力隨鋼絲繩逐步加載過程變化的規律進行了研究，發現最大應力產生在鋼絲繩繞過后3 ~ 5圈截面處，該現象與理論分析結果也是符合的。 -
Problems occured in the anchoring of overhung tourist hall on top of the tv tower and tower drum due to construction mistakes. it was introduced in this paper that two non - binding prestressed girder beams are respectively set in corresponding locations as the anchor beam of overhung radial support beam of tourist hall, thus the integrity of the tower drum and transmission of the load were guaranteed
由於施工失誤，作為電視塔頂的外懸游覽廳和塔筒間的錨固發生了問題，本文介紹了採用在相應位置設置兩根無粘結預應力大樑分別作為游覽廳屋面和樓面徑向懸挑支承梁的錨固梁，確保了它和塔筒的整體性和荷載的傳遞。 -
A stationary motor - driven or hand - powered hoisting machine having a drum around which is wound a rope or chain attached to the load being lifted
絞車，起貨機一種裝有捲筒的固定的電動機驅動或手動的吊升機械，捲筒周圍纏繞著與提升的重物相連的繩索 -
During unit startup and load is lower than 15 %, drum level is controlled by feedwater control valve, feedwater pump remains at minimum safety speed ; when load is between 15 % and 25 %, feedwater control valve is closing at fixed speed determined by function module, main motor - operated - valve is opened automatically, control mode of drum level is transferred to feedwater pump automatically and bumplessly ; when load is between 25 % and 50 %, control valve is closed fully, and main motor - operated - valve is open fully, drum level is controlled by one pump ; when load is more than 50 %, first pump is kept in operation, second pump is putting into operation automatically and
在機組啟動、沖轉及機組並網至15 %負荷階段，給水泵維持在最低安全轉速下運行，汽包水位由低負荷給水調節閥自動控制; 15 %至25 %負荷階段，給水調節閥由函數模塊按照一定的速率自動平滑關閉，主給水電動門自動打開，汽包水位控制方式自動無擾切換為給水泵自動控制;負荷在25 %至50 %階段時，給水調節閥已完全關閉，主給水電動門已完全打開，水位控制已全由單臺給水泵承擔;負荷大於50 %后，在第一臺給水泵運行的同時，第二臺給水泵自動無擾投入。
