What should be paid attention to when using multi effect distilled water machine

Multi effect distilled water machine is a kind of distilled water production equipment, which uses deionized water as raw water and uses steam to heat it The distilled water produced by the equipment has stable quality, high purity and no pyrogen It is in line with the provisions of "water for injection" in Chinese Pharmacopoeia (version 05) It is an ideal equipment for pharmaceutical manufacturers and drinking distilled water production plants, such as blood products, injections, large infusion, biological antibiotics, etc The evaporator of multi effect distilled water machine is equipped with a special structure of steam water separation device, which can effectively remove the mist drops and impurities in the steam, so as to ensure the quality of distilled water When using the multi effect distilled water machine, we should pay attention to the following items: 1 Ensure that there is enough pure water in the pure water storage tank for operation, and timely produce when it is insufficient, so as to ensure the safe operation of the distilled water machine
2 Test the pure water, the result should meet the standard index required by GMP, the pH value test standard is 5-7, the conductivity test standard is less than 2 μ s / cm, the chloride (Cl -) free chlorine can not exceed the standard, the test diluted silver nitrate, drop a drop of solution in 100ml purified water, if there is white precipitation in the pure water, it means that (Cl -) exceeds the standard, the pure water in the storage tank is not It can enter the distilled water machine, which must be strictly observed 3 The pure water pump of the distilled water machine must be drained before starting to ensure the safe operation of the water pump 4 When the machine is shut down, the feed water valve (MV03) must be closed first, which is mainly to prevent the backflow of water in the water inlet pipe and the high-temperature water from rushing into the glass pipe of the flowmeter (fs01), so that the glass will burst.
