對發電機內進行補氫,排污應留意如下問題:

For hydrogen replenishment in generators, the following issues should be noted in sewage discharge:

(1)排污補氫前應做好聯絡工作,說明所要操作的內容;

(1) Liaison work should be done before sewage discharge and hydrogen replenishment, and the contents of operation should be explained.

(2)敞開閥門前要精確核對閥門號,以防誤操作;

D88尊龙(2) Before opening the valve, check the valve number accurately to prevent misoperation.

D88尊龙(3)敞開補氫或排污閥門要緩慢,制止運用鐵搬手敞開閥門,避免出現火花;

(3) Opening the valve for hydrogen replenishment or sewage discharge should be slow, so as to prevent the use of iron handlers to open the valve and avoid sparks;

D88尊龙(4)向機內彌補的新鮮氫氣純度不得低于99.5%,氧量和其他氣體的含量不得大于0.5%,氫氣絕對濕度不大于5克/米3;

(4) The purity of fresh hydrogen, oxygen and other gases should not be less than 99.5%, and the absolute humidity of hydrogen should not be less than 5 g/m 3.

(5)補氫或排污時留意在答應的壓力范圍內進行,留意氫壓和密封油壓的變化,避免壓力過高或過低影響機組的安全運轉;

D88尊龙(5) When making up hydrogen or sewage, pay attention to the allowable pressure range, pay attention to the change of hydrogen pressure and sealing oil pressure, and avoid the influence of too high or too low pressure on the safe operation of the unit;

(6)排出的氣體按指定管路排出廠房外,不要把氣體排在室內;

D88尊龙(6) The exhaust gas should be discharged out of the factory building according to the designated pipeline, and should not be discharged indoors.

D88尊龙(7)補氫和排污完畢后,要查看閥門封閉正常,機組上,下部壓力表指示共同.并通知有關人員補氫排污完畢;

(7) After the completion of hydrogen replenishment and sewage discharge, check that the valves are normally closed, the pressure gauges at the upper and lower parts of the unit indicate the same, and notify the relevant personnel that the hydrogen replenishment and sewage discharge are completed;

(8)排污完畢后,應及時聯絡化學化驗人員進行取樣化驗,直至發電機氫氣參數合格.

(8) After the sewage discharge is completed, the chemical laboratory personnel shall be contacted in time for sampling and testing until the hydrogen parameters of the generator are up to standard.
