对发电机内进行补氢,排污应留意如下问题:

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

(1)排污补氢前应做好联络工作,说明所要操作的内容;

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

(2)敞开阀门前要精确核对阀门号,以防误操作;

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

(3)敞开补氢或排污阀门要缓慢,制止运用铁搬手敞开阀门,避免出现火花;

(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;

(4)向机内弥补的新鲜氢气纯度不得低于99.5%,氧量和其他气体的含量不得大于0.5%,氢气绝对湿度不大于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)补氢或排污时留意在答应的压力范围内进行,留意氢压和密封油压的变化,避免压力过高或过低影响机组的安全运转;

(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)排出的气体按指定管路排出厂房外,不要把气体排在室内;

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

(7)补氢和排污完毕后,要查看阀门封闭正常,机组上,下部压力表指示共同.并通知有关人员补氢排污完毕;

(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)排污完毕后,应及时联络化学化验人员进行取样化验,直至发电机氢气参数合格.

(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.
