4.2 from the bottom of the generator filled with nitrogen or carbon dioxide gas, the exhaust gas from the upper part of the generator ,, maintain pressure within the generator at 2.94 × 10-3 ~ 5.88 × 10-3Mpa, and is discharged from the gas sampling and analysis, gas less than 3% oxygen content, carbon dioxide content greater than 85% of the electrical discharge notice dead, dead after row to stop replacement.
4.3 from the upper part of the generator filled with hydrogen, the exhaust gas from the bottom of the generator to maintain the power generator hydrogen 2.94 × 10-3 ~ 5.88 × 10-3Mpa, sampling and analysis from the exhaust gas, when the hydrogen purity greater than 96%. Oxygen content of less than 2%, the electrical discharge notice dead, dead after row, can be put into hydrogen purity meter, when the machine is raised to 0.294Mpa after fill hydrogen into automatic valves.
5.1 is converted to hydrogen-cooled by the air-cooled (intermediate medium method)
5.2 from the bottom of the generator filled with carbon dioxide gas, when analyzing exhaust gas or hydrogen content of less than 3% of the carbon dioxide content greater than 95%, the electrical discharge notice from the exhaust pipe sample dead, dead stop after row replacement.
5.3 from the upper part of the generator filled with compressed air, carbon dioxide gas is discharged from the bottom, from the exhaust gas sampling and analysis, when the carbon dioxide content of less than 10% is converted to air cooling.

Fifth, the normal operation and management
1 Under normal circumstances, the operator should always observe the operation of equipment, proper operation and timely recording parameters and exceptions, every two hours recording time, faced unusual circumstances promptly shut down processing.
2 according to the amount of hydrogen required by the situation, at any time adjust the power rectifier cabinet, rotary potentiometer output rectifier cabinet can not be too fast, to prevent over-current fault.
3 in the operation selector switch rectifier cabinet can not be arbitrarily changing positions, otherwise a fault will occur. To change the rectifying cabinet running, it must output potentiometer set to zero, in order to convert the position of the switch.
4 measured once each boot lye proportion, such as concentrations of less than 20%. It should supplement lye. Up base should be added at the time of shutdown. Complementary approaches: an open base box base valve 6A, open lye small circulation pump into the base cutting 8A, start circulating pump, circulating pump to open the exhaust valve, the exhaust air after closing open lye circulating regulation valve 7A, the base hit. into the cell, after lye finished, stop the circulation pump, shut alkali lye small circulation pump inlet valve 8A, the base tank base valve 6A.
5 Have the tank frequently observed demineralized water and the cooling water flow is normal.
.6 Frequently observed hydrogen, oxygen analyzer and a gas flow meter desiccant discoloration, the timely replacement of the desiccant and adjusting the flow rate and boric acid tablets.
7 regularly clean the filter, first turn when general cleaning once a week, three months after each cleaned once a month, clean the filter should be carried out at the time of shutdown, first turn off the filter inlet and outlet doors, folding under the filter cover, remove a filter with demineralized water will clean, and then loaded into the filter, installed flange cover, it can be used after confirmation does not leak.
8 Note lye circulation amount can not be too large or too small, to regulate the amount of circulating through the lye circulation regulating valve.
9 every month for each alarm equipment and protection equipment to conduct a test signal test before starting every year to deal with a full set of equipment for repair and instrument calibration.
On (pilot projects aerobic liquid limit; on liquid hydrogen, lower limit; upper trough pressure; hydrogen pressure limit; lower limit of the gas source; bath temperature limit; lower limit of the amount of alkali circulation and other alarm hydrogen side, the oxygen side, the cooling water control valve film. switch test groove pressure is too high, the bath temperature is too high, the lower limit of the amount of circulation, control cabinet interlock.)
10 cell overhaul, replace all asbestos diaphragm and gasket overhaul every five years.
11 rectifier cabinet as a failure in the operation, should be excluded after fault current, voltage, given counterclockwise rotation in the end, press the reset button, and then restart.
12 weekly water hydrogen machine, a dryer gas-liquid separator sewage once.
13 Analysis of hydrogen purity once every two hours, copy hydrogen hygrometer hourly, every four hours once a manual analysis of hydrogen humidity and the results to fill in the report.
14 monthly daytime replace Austria's gas analyzer used drugs.
15 Tuesdays analysis of the hydrogen storage tank of hydrogen purity (≥99.5%), Wednesday analysis of the hydrogen storage tank of hydrogen gas humidity (≤-25 ℃), if failed, the report shall monitor and inform the Ministry of drainage and electricity In other hydrogen until qualified.
16 Zero class of each hydrogen storage tank drain again.
17 rows of work at stake hydrogen, hydrogen Point sampling was conducted to carefully, carefully, to ensure accurate, and the last three times the sample to be analyzed, and verified correct, in order to pass.
