Embodiment 1
[0029] A maintenance device for ultra-long-term maintenance of reference electrodes, see appendix figure 1 and attached figure 2 , including the liquid storage tank 10, the main pipeline 20 connected to the liquid outlet of the liquid storage tank, the liquid inlet pipeline 30 connected to the main pipeline 20, the gravity replenishment pipeline 40 connected to the main pipeline 10 and the liquid inlet pipeline 20, and the liquid inlet pipeline 30 passes through the first A branch pipe 501 and a second branch pipe 502 are respectively connected to the reference electrode 60 .
[0030] The first branch pipe 501 is connected with a first flush pipe 701, the second branch pipe 502 is connected with a second flush pipe 702, the main pipe 20 is provided with a liquid storage tank outlet valve PV1, and the liquid inlet pipe 20 A magnetic pump 201 is provided on it, the first branch pipe 501 and the second branch pipe 502 are respectively provided with a backwash valve PV6 and a re...
Embodiment 2
[0037]The difference from Example 1 is that the gravity replenishment pipeline 40 is not provided, and the continuous replenishment of the saturated CuSO4 solution also relies on the liquid inlet pipeline 30 . That is, the reference electrode is continuously replenished with saturated CuSO4 solution daily. The operation is: open the outlet valve PV1 of the liquid storage tank, the pump outlet valve PV4 and the reference electrode inlet valve PV3, close other valves, and open the magnetic pump to add liquid. Compared with Example 1, A certain amount of power is required.
