Low voltage switch: one of the switches to control the start and stop of water purification products. When the tap water pressure reaches the set value, the low-voltage switch will start and the machine will run automatically. When the water inlet is closed or the water pressure is insufficient, the low-pressure switch will automatically close, cutting off the water-making circuit and protecting the pump from idling. ?
High voltage switch: always open. When it is sensed that the pressure barrel of the water storage barrel reaches the set value (0.25Mpa), it will automatically shut down and the water purifier will stop purifying water. When the water source in the pressure barrel is less than the set value, the high-pressure switch will continue to be started to restore the water-making effect. Prevent the machine from continuously producing water and leaking water. ?
Water inlet solenoid valve: to prevent water circulation after the machine stops working. Prevent the filter element from being continuously affected by water pressure to make water. Prevent the RO membrane from being blocked, resulting in the continuous outflow of wastewater. ?
Flushing solenoid valve: an accessory used to flush the film in the machine. When the membrane absorbs too many impurities, the flushing solenoid valve can be started for cleaning, thus improving the service life of the membrane. ?
Pressure barrel: a container for storing water and draining water, which helps the water purifier to store and release water through internal pressure setting. The bigger the pressure barrel, the more water it stores, which will increase the daily water output of the machine.
Check valve and one-way valve: prevent water from flowing backwards when the pure water machine stops making water. The protective film and filter element are not affected by water flow.
PP cotton filter element: The first and third filter materials of the water purifier are specially made of food-grade polypropylene, which is used to filter impurities such as sediment and rust contained in water. The scale is 10 micron-1 micron, and the service life is 6- 12 months. ?
Granular activated carbon: produced by organic activated carbon, it can adsorb and improve impurities such as residual chlorine, abnormal color and odor in water, and its service life is about 12 months.
RO membrane (or ultrafiltration membrane): The filtration accuracy of RO membrane is as high as 0.000 1 micron, which can filter almost all substances in water except water molecules to obtain purified water. The filtration accuracy of Li Sheng ultrafiltration membrane is 0.0 1 micron, which can remove secondary pollutants such as sediment, rust, colloid and bacteria from tap water, while retaining minerals and trace elements in water.
Post-activated carbon: It is a finer filtering consumable than granular activated carbon. Its advantage lies in absorbing different colors and smells in water, improving the taste of water, decomposing micro-energy in water and bringing more harsh nutrition to human drinking water.
