Matters needing attention during the operation of pure water equipment
Takes note of articles running water equipment: water equipment consists of reverse osmosis equipment, and a mixed bed polishing mixed bed composed of three parts. reverse osmosis equipment is a pretreatment, which mainly plays a role of filtering, filtering out impurities and bacteria. The mixed bed and polishing mixed bed are mainly the function of pure water. Pure water equipment operation process 1. Before starting the pure water equipment, check whether the valve of the water inlet pipe is kept open, whether the power supply is plugged in, and the reverse osmosis water tank meets at least half of the water volume before the system can be turned on for water production. 2. Under normal startup conditions, the pressure range of reverse osmosis equipment high pressure control (0-1.6MPA) is between 0.8-1.0Mpa, the scale of pure water flow float is above 1000ml, the scale of concentrated water flow float is 1200-1500ml, and the conductivity is ≤ 20us/cm (25℃) is qualified. 3. Check whether the valves of the mixed bed system are in normal state of water production. When the machine is turned on, the scale of the flow float of the mixed bed is around 1000ml, and the resistivity of the mixed bed is more than 5 megohms (25℃), which is qualified, and it is less than 5 megohms. It is recommended to refer to the regeneration instructions for regeneration operation. Only when the high-purity water tank meets half of the water volume can the polishing mixed bed water production be started. 4. Check whether the manual valve group of the polishing mixed bed remains open, and turn on the delivery pump 2 to start water production and delivery by the ultrapure water equipment. Under normal starting conditions, the resistivity of the polishing mixed bed is 2, 17-18 megohms (25°C), which is qualified. If it is lower than this value, the polishing resin needs to be replaced in time. 5. Shutdown preparation: When shutting down, you can directly turn off the main power supply. The above are the matters needing attention in the operation of pure water equipment for environmental protection. If you don't understand, please come to consult.
