Description and Function of Each Part
Principle of Operation
3. Flow of Cooling Water
During distillation, water is supplied and discharged in the order: (1) pressure-reducing valve, (3) cooling
water solenoid valve and condenser (14). When the distilled water tank is full, or when ion exchanged water
is sampled, distillation is stopped, and the cooling water is also stopped automatically.
4. Sampling of Distilled Water
For 10 minutes after starting distillation, initial distilled water condensed in condenser (14) is drained by
opening initial accumulated water drain solenoid valve (18). Then distilled water is stored in distilled water
tank (25) by distilled water quality gauge electrode (16). Distillation stops as the tank is full when float switch
3 (26) on the top in the tank operates. The stored water is collected by distilled water sampling pump (28)
through distilled water sampling solenoid valve (20), distilled water flow sensor (22), distilled water sampling
port (24), and membrane filter (32).
