1. The hydrogen generator cannot be started
Fault cause: (1) the circuit is not connected; (2) The hydrogen switch power supply is damaged; (3) The electrolytic cell is burnt out during no-load operation with pressure of 0.
Check methods: (1) check the circuit; (2) Use a multimeter to measure whether the voltage of the electrolytic cell is about 2.3V.
Cleaning methods: (1) repair the power supply; (2) Replace the damaged hydrogen switch power supply; (3) Replace the electrolytic cell.
2. The hydrogen production fails to reach the predetermined pressure, and the hydrogen digital display is more than 500ml / min, that is, the display amount of the instrument exceeds the actual application amount
Fault causes: (1) air leakage in air circuit system; (2) The filter or the upper cover of the filter is not tightened; (3) Back leakage of hydrogen electrolytic cell.
Inspection method: use leakage detection liquid to detect the joints of each gas circuit. Cleaning methods: (1) replace the air leakage element; (2) Tighten the air leakage point; (3) Contact the manufacturer to replace the electrolytic cell.
3. Hydrogen production exceeds the predetermined pressure by 0.1MPa
Fault causes: (1) the light shield of the automatic tracking device is misplaced or falls off; (2) Photoelectric coupling is damaged.
Inspection methods: (1) visual inspection; (2) Measure the circuit with a multimeter.
Cleaning method: (1) when the pressure on the front panel reaches 0.3MPa, turn off the power supply, install the light baffle at a reasonable position, turn the power switch and gently tap the light baffle; (2) Replace the damaged optoelectronic coupling element.
4. The generator can be started, but the digital display of hydrogen appears as 0 or black screen.
Fault cause: the digital display meter is damaged.
Check method: measure the circuit with a multimeter.
Cleaning method: replace the digital display table.
5. After startup, the hydrogen production cannot reach 300ml / min or it takes a long time to reach
Fault causes: (1) electrolyte failure; (2) The switch is not tightened and there is air leakage.
Inspection methods: (1) investigate whether the liquid level of electrolyte is lower than the lower limit or the electrolyte is used for more than half a year; (2) Leak test.
Cleaning methods: (1) add secondary distilled water or deionized water in time. Or pour the cooled electrolyte (mother liquor) of the new equipment into the liquid storage tank, and then participate in the secondary distilled water or deionized water. The water level is between the lower limit of the water level line (the concentration of potassium hydroxide solution is about 10%). Screw on the outer cover, and it can be used after 10min; (2) Continuously tighten the switch to make the pressure and flow of the instrument meet the standard.
How is the failure of the hydrogen generator caused
6. After startup and operation, the hydrogen production cannot be stable and has been shaken in a small range.
Fault cause: electrolyte failure.
Inspection method: investigate whether the liquid level of electrolyte is lower than the lower limit or the electrolyte has been used for more than half a year.
Cleaning method: replace or add water with 10% potassium hydroxide electrolyte.
7. After startup, the hydrogen production slowly increased from tens of ml / min, and the pressure could not reach 0 within 5 arin. 3MPa
Fault cause: electrolytic cell leakage.
Inspection method: visual inspection.
Cleaning methods: (1) tighten the screws after clamping the electrolytic cell with a vise; (2) The sealing part shall be firmly adhered with plane sealant; (3) Replace the electrolytic cell for irreparable mechanical damage.
8. The instrument is severely corroded and cannot be used
Fault causes: (1) the electrolyte was not cleaned by ear ball during transfer; (2) The inner cover and the outer cover are not screwed properly, so that the residual electrolyte overflows during transportation.
Inspection method: visual inspection.
Cleaning method: replace the instrument.
