Precautions for putting emergency sealing oil pump 100LY-62 into operation
Date:2023/5/8 10:30:25 Visits: Author:Dongfang YOYIK Engineering Co; Ltd,Precautions for putting emergency sealing oil pump 100LY-62 into operation
1. When the emergency sealing oil pump 100LY-62 is put into operation, due to the fact that the oil from the system does not pass through the vacuum oil tank and cannot be purified, the air and moisture contained in the oil may diffuse into the generator with the hydrogen side return oil, resulting in a decrease in hydrogen purity. At this time, monitoring of hydrogen purity should be strengthened. When the purity of hydrogen significantly decreases, timely discharge should be carried out, and then high-purity hydrogen should be fed into the generator through the hydrogen main pipe.
2. If the emergency sealing oil pump 100LY-62 is put into operation and the main oil pump cannot return to normal working state for a long time, the valves on the vacuum oil tank refueling pipeline and the inlet valve of the vacuum pump should be closed, the recirculation pump and vacuum pump should be stopped, and then the vacuum breaking valve should be operated, and the vacuum oil tank should be withdrawn from operation.
