Characteristics of Lamellar Oxygen Pumps

For the purification of liquid metal from oxygen, the voltage (/ Pq has to be applied from the external DC source with the negative polarity on the liquid-metal electrode. The transfer of oxygen ions to the gaseous electrode can result in the following chain reactions

In other cases, the use of the oxygen pumps carries out in galvano-stalic mode, that is, at the constant current in circuit (4.43). Let us consider the main calculated characteristics of such pumps, which can be represented by the speed and depth of the liquid metal purification from oxygen as well as by the oxygen flow and by the time of the attainment of the set deepness of purification.
