How to disassemble the water purifier
< br >
1, inlet ball valve, pure water machine total inlet valve, open the inlet ball valve, tap water into the pure water machine, the installation position is located in the inlet tee side, easy to turn off the water source when maintenance.
< br >
2, PP cotton filter, pore size 5 microns, sedimentary filter, remove dust, rust, gravel and other substances greater than 5 microns.
< br >
3, low pressure switch, when the water pressure reaches 1.5kg\/cm2, turn on the power to make the machine run normally; When the water is cut off, or the water pressure is less than 1.5kg\/cm2, the power is cut off, and the machine sends a buzzer alarm.
< br >
4, high pressure pump, pressure to tap water up to 5-8 kg\/cm2, to meet the pressure and flow requirements of RO film water.
< br >
5, granular activated carbon filter, pre-filtration, remove chlorine odor, methane, pesticides, fertilizers and other substances.
< br >
6, the third stage PP cotton filter, pore size 1 micron pre-filtration, remove fine particles due to activated carbon fall off.
< br >
7, water inlet solenoid valve, when the power supply is connected, tap water through the inlet solenoid valve, so that the pure water machine normal water; When the machine stops, the water source is cut off, preventing the water from passing through and draining away through the concentrated waterway.
< br >
8, RO membrane, also known as reverse-impregnated membrane, it relies on the pressure exerted by the machine on the raw water, so that the water in the raw water passes through the RO membrane, and the fine impurities in the raw water, too much inorganic salts, organic matter, heavy metal ions, bacteria, viruses, pesticides, trichloromethane waste and other harmful substances are all intercepted. And through continuous discharge of concentrated water to remove harmful foreign bodies and salts in these waters, and then get very clean drinking water. Its aperture is only 0.0001 micron, and its removal rate of the smallest inorganic salt ions in water is more than 90-96%, and the removal rate of harmful foreign bodies such as bacteria and viruses is more than 99.99% (in theory, it can be said to be 100%).

Bacterial, viral and RO membrane pore size comparison:

9. Check valve, also called check valve in engineering, pure water is full, and the pressure reaches 3kg\/cm2 to prevent high pressure pure water from flowing back with wastewater.
< br >
10, high pressure switch, automatic control of pure water machine work, when the water pressure reaches 3kg\/cm2, cut off the power supply, so that the pure water machine stop; Pure water discharge system (such as opening the tap water), water pressure is reduced, reduced to 1.5kg\/cm2, automatically switched on the power supply, so that the machine into the normal state of water.
< br >
11, pressure storage bucket, store pure water for backup, air pressure 0.4-0.8kg \/cm2.
< br >
12, the air nozzle, to the pressure water storage bucket air or air.
< br >
13, pressure bucket ball valve, pressure water storage bucket inlet or outlet valve.
< br >
14, after the antibacterial activated carbon, remove odor to make the water sweet, to avoid the pressure water storage tank pure water secondary pollution.
< br >
15, Gooseneck faucet, access to pure water switch.
< br >
16, waste water proportioner, so that concentrated water is discharged, limited flow through the small hole pressure, to ensure the working pressure of RO membrane. The ratio of concentrated water to pure water is 1:3-1:5. Its function is to control the flow rate and ensure a constant system pressure.
< br >
17, flushing solenoid valve, automatically controlled by the machine (computer board), the total work of pure water machine 7.5 hours, the power supply is switched on once, the RO film for high pressure and large flow washing, flushing time 1 minute 40 seconds. Installation knowledge of pure water machine (1), assembly machine: 1, install the filter element, the order is from right to left, PP cotton, granular activated carbon, PP cotton. PP cotton installation has no direction, particle activated carbon with rubber pad end corresponding to the direction of the head. At the same time, put the rubber pad in place and remove the heat shrink film. Check the sealing surface, bottle and sealing ring for any big defects. Apply some medical Vaseline to the sealing ring and tighten it with a plate handle.

Water purifier is now the most commonly used household water purification equipment, it is also known as water purifier. The core technology adopted by the water purifier is the filter membrane in the filter element device, of which the type of filter element can be divided into ultrafiltration membrane and RO reverse osmosis membrane according to the classification of technology. The water purifier can not only filter out the toxic substances in the water, but also effectively solve the endemic diseases caused by excessive harmful substances in the groundwater in many places. The water it filters is very clean and safe, and it also provides great protection for people's health.
