3, low-pressure switch: when the raw water pressure is insufficient, the low-pressure switch is about to cut off the power supply to prevent the pump from idling. Raw pressure is generally 3-4 kilograms.
4, the computer board: it receives information from various components, the machine work, stop, flush control.
5, water inlet solenoid valve: the machine works to open the water source of an electric switch, the machine stops working, it cuts off the power supply to stop the role of wastewater.
6, flushing solenoid valve: its role is when the need to flush, after receiving the instructions of the computer board, automatically open the proportion of wastewater short-circuiting, improve the flow of wastewater, RO membrane flushing.
7, wastewater ratio: control the proportion of wastewater and pure water.
8, pressure drum: storage of pure water pressure vessel, it has an internal pressure, generally 0.7kg.
9, check valve: is to prevent the pressure drum in the pure water backflow of a one-way valve.
10, transformer: 220V electricity into 24V safety voltage.
Cartridge FunctionCartridge FunctionCartridge FunctionCartridge Function:
PP Cotton: primary filtration of raw water, remove coarse particles of impurities in water, sludge, colloids, suspended substances.
Granular activated carbon: adsorption of odor, color, organic matter, some heavy metals, etc.
Carbon activated carbon: further removal of chlorine, organic compounds, color, odor, turbidity and so on. RO reverse osmosis membrane: pore size of 0.1 nanometers, remove water bacteria, viruses, heavy metals, and other organic impurities. Post-activated carbon:Adjust the PH value of the water, improve the taste.
It uses mainly reverse osmosis membrane technology. Its working principle is to apply a certain pressure to the water, so that water molecules and ionic mineral elements through the reverse osmosis membrane, and dissolved in the water of the vast majority of inorganic salts (including heavy metals), organic matter, as well as bacteria, viruses, etc. can not pass through the reverse osmosis membrane, so that the infiltration of the pure water and can not be infiltrated through the concentration of the water is strictly separate; reverse osmosis membrane pore size is only 0.0001 microns, and the viral The diameter of the reverse osmosis membrane is only 0.0001 microns, while the virus is generally 0.02-0.4 microns, the diameter of the ordinary bacteria is 0.4-1 microns, so you can rest assured that the drinking water purifier out of the spring.
