ONLY QUALIFIED AND COMPETENT PERSONNEL MUST CARRY OUT ANY MAINTENANCE OPERATION. 只有經(jīng)過培訓的有經(jīng)驗的技術(shù)人員才能維修設(shè)備。 The ash gates are operated using the local control panel and are powered by a hydraulic power pack mounted on the Ash Well platform. The control system opens and closes the gate in a stepwise sequence, each gate having an open and closed limit to confirm the gate location. 渣井關(guān)斷門用就地的控制盤來操作，由放置在渣井平臺上的液壓動力站來推動它。C。 The conveying chain is of the round link design and has a surface hardness of 800 HV minimum. The wear edges of the conveying flight bars are of abrasive resistant material and are designed to have a minimum of 16000 operating hours. Bearing service life is in the order of 40000 operating hours and the submerged bearings are suitable for operation between a temperature range of 20186。 A hydraulic power pack is installed at the base of the conveyor incline and is suitably designed to drive the conveyor at all times under all modes of operation. The maximum forward speed of the chain is m/min and SSC trough pletely full of ash. 液壓動力站安裝在斜升段的底部，合理設(shè)計以保證在各種工礦下工作。 The crusher is designed to acmodate the maximum tonnage rates of the SSC. The crusher drive is hydraulic and oil is supplied from the same hydraulic powerpack as the SSC. The crusher is mounted on rails for easy removal to the maintenance position. 碎渣機的設(shè)計來適應(yīng)撈渣機的最大排渣量。 A screw take up arrangement at the tail end effects the chain tensioning. 尾部螺旋升起的裝置有助于鏈條的張緊。ID ASH WELL RETRACTABLE DOORS 渣井關(guān)斷門 C6196003 BOTTOM ASH HANDLING SYSTEM – UNIT 3 底渣處理系統(tǒng) 3號機組 Pamp。渣井關(guān)斷門和撈渣機行走輪驅(qū)動僅由就地盤控制。通過最渣機的底渣被二級刮板運輸至渣倉。 Buyer : Guangdong Guohua Yeudian Taishan Electric Power Plant Project : Taishan Power Plant Phase I 3 x 600MW CBMH Project No. C6196 Contract No. 2020RCC/13069UK Document No. C6196/MM/1 Operating and Maintenance Instructions 19 For maintenance the SSC can be removed by locally controlled wheel drives. When enabled locally the SSC will be disabled and the operator can run the drives forward or reverse. During SSC removal ash gates will be closed to isolate the boiler and stop ash falling through to ground. A maintenance switch on the local ash gates local control panel will enable the ash gates to be operated when the SSC is removed. 維修時撈渣機通過就地控制的驅(qū)動被移出。 Periodically
