2, the maximum working pressure of the machine is 0.5MPa, the safety valve is set at 0.52MPa, the safety valve handle should be lifted regularly to check the effectiveness of the valve.
3, the cleaning of the machine Distilled water machine in long-term operation, if the production capacity of the decline or the decline in water quality, sure that there is dirt deposited on the surface of the heat exchanger tube (focusing on the first effect of the evaporator and condenser), should be considered to clean the machine, so as to return to normal conditions.
1) cleaning solution ratio
① all deionized water dosage
② acid detergent: the choice of phosphoric acid, concentration of 5-10%, the temperature remains 60 ℃.
③Neutralizing agent: choose sodium carbonate or sodium bicarbonate aqueous solution, concentration 0.5-1%, the temperature is maintained at 80-100 ℃.
Note: Selection of acid detergent, neutralizing agent should ensure that the equipment does not damage the pipeline material.
2) Operation.
Open the water inlet valve, the pickling solution from the water inlet into the machine, discharged from the outlet of the unqualified water for injection, other valves are closed, repeated cycle for many times, the cycle time is determined according to the condition of the dirt, dissolve 1mm thick dirt for about 18 hours.
After pickling, the cycle is repeated with neutralizing solution for 3-5 hours.
Finally, use ionized water to recirculate rinse for 3-5 hours, check whether the discharged rinse water is completely neutral until it can be put into normal operation.
4, machine disinfection
The distilled water machine should be disinfected after a long period of operation or a long time to stop and restart. Specific operation method is: according to the normal operation method to start, make its normal operation, and then close the raw material water, cooling water, so that the steam rushes into the evaporator, preheater and through the distilled water pipeline into the condenser, through the distilled water outlet and non-condensable gas discharge, repeat the above operation for many times, you can achieve the purpose.
5, operation precautions
A, the operator should confirm that there is enough water in the pure water storage tank.
B. Make sure the three-phase power supply is not in phase.
C, to confirm that the purified water is not acidic or alkaline, not chlorine, if the above three phases of the serious overrun can not start running, otherwise the machine will be seriously damaged, or even scrapped.
D, must comply with the manufacturer's specified operating procedures.
E. When cleaning the surface of the equipment with water, the electric control device is well protected.
