During liquid level sensor 8, suction pump 92 is opened, by the electrolyte pumping in fluid reservoir 2 into feed tank 11；When in feed tank 11
When electrolyte is increased to high liquid level sensor 81, suction pump 92 is closed, and stops pumping electrolyte into feed tank 11.Pass through setting
Liquid level sensor can carry out supplement electrolyte to it according to the height of liquid level in feed tank 11, ensure high-purity hydrogen generator
Can the continuous firing long period, reduce the number of artificial supplementation electrolyte, improve the degree of automation of equipment.
Fluid reservoir 2 is mainly used for endlessly providing electrolyte into feed tank 11, once the electrolysis inside fluid reservoir 2
, it is necessary to stop high-purity hydrogen generator in time when liquid is exhausted, so as to avoid the consumption of electric energy, equipment is avoided to be damaged.
In order to solve the problems, such as this, fluid reservoir 2 is internally provided with the second low liquid level sensor 9, and the tank deck of fluid reservoir 2 is provided with
Audible-visual annunciator 10, when the electrolyte of fluid reservoir 2 is consumed down to the second low liquid level sensor 9, the second low liquid level sensor 9 connects
The collection of letters number controls audible-visual annunciator 10 to carry out sound-light alarm, operating personnel is prompted to be mended in time into fluid reservoir 2 by control circuit
Fill electrolyte.
Further, the 3rd low liquid level sensor 91 is additionally provided in fluid reservoir 2, the 3rd low liquid level sensor 91 is vertical
Less than the second low liquid level sensor 9 on direction, once operating personnel do not obtain alarm, electrolyte can persistently disappear
Consumption, causes the electrolyte in fluid reservoir 2 to be exhausted, causes waste of energy, can seriously destroy electrolytic cell 3.By setting the 3rd
Low liquid level sensor 91, when the liquid level of electrolyte is consumed down to three low liquid level sensors 91, the 3rd low liquid level sensor
91 transfer electric signal, by after electric control, being closed for electric installation 4 for high-purity hydrogen generator stops electrolysis.
It can be to electrolyte by 81 and first low liquid level sensor 8 of high liquid level sensor set inside feed tank 11
Liquid level carries out automatically controlling, and staff need not operate high-purity hydrogen generator at the moment, liberate operating pressure；It is in addition, logical
2 liquid storage of fluid reservoir is crossed, can be that feed tank 11 persistently provides electrolyte, extend the working time of high-purity hydrogen generator, carry
High hydrogen generation amount, the low alarm of liquid level, the 3rd low liquid level sensor can be carried out by the second low liquid level sensor 9 of setting
91 can automatically power off when 2 electrolyte inside of fluid reservoir is depleted, avoid causing the loss of electric energy and the damage of equipment.
This specific embodiment is only explanation to the utility model, is not the limitation to the utility model, ability
Field technique personnel can as needed make the present embodiment the modification of no creative contribution after this specification is read, but
As long as it is all protected in the right of the utility model be subject to Patent Law.
