The water purifier is used to deeply filter and purify the water according to the requirements for use of water. Nowadays, safe drinking water is the water filtered by the water purifier. The choice of water purifier is also very important. The purchase of water purifier accessories can not be ignored at the same time. Therefore, consumers need to master some. Skills, then, what are the functions of the water purifier accessories ? How to buy water purifier accessories?
First, the role of water purifier accessories
1, PP cotton filter: pore size of 5 microns, before the deposition type of filtration, remove dust, rust, gravel and other substances larger than 5 microns.
2, granular activated carbon filter: pre-filtration, remove chlorine odor, methane, pesticides, fertilizers and other substances.
3. The third-stage PP cotton filter: pre-filtration with a pore size of 1 μm to remove fine particulate matter due to the shedding of activated carbon.
4. Inlet water ball valve: The water inlet machine always enters the water valve, opens the water inlet ball valve, and the tap water enters the water purifier. The installation position is located at the inlet side of the water inlet, which is convenient for shutting off the water source during maintenance.
5. Low-voltage 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 emits a buzzer alarm. Prevent the pump from idling (when the source water pressure is lower than 0.5 kg/cm 2 or the water is stopped, the low-voltage switch automatically cuts off the power to stop the machine.)
6. Inlet water solenoid valve: When the power is turned on, the tap water passes through the water inlet solenoid valve to make the water purifier water normally; when the machine stops, the water source is cut off, the water is prevented from passing, and the water is drained through the concentrated water channel.
7. High-pressure pump: pressurize tap water to 5-8 kg/cm2 to meet the pressure and flow demand of RO membrane water. To the role of supercharging, the RO membrane can work normally and create a stable working environment. Working pressure: 6-8 kg / cm 2, equivalent to 100 PSI
8, RO membrane: also known as reverse osmosis 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, while the fine impurities in the raw water, excessive inorganic salts, organic matter, heavy metal ions, bacteria Other harmful substances such as viruses, pesticides, chloroform waste, etc. are all intercepted, and the harmful foreign matter and salt in these waters are discharged through the continuous discharge of concentrated water, thereby obtaining very clean drinking water. Its pore size is only 0.0001 micron, its removal rate of inorganic salt ions with the smallest particle size in water is above 90-96%, and the removal rate of harmful foreign substances such as bacteria and viruses is above 99.99% (in theory, it can be said to be 100%). ).
9. Check valve: It is also called check valve in engineering. After the water is full, the pressure will reach 3kg/cm2, and the high pressure water backflow will be prevented from being discharged together with the waste water.
10, high-voltage switch: automatic control of water purifier work, when the water pressure of pure water reaches 3kg / cm2, cut off the power supply, so that the water purifier is shut down; pure water discharge system (such as open the faucet discharge), water pressure is reduced, minus When it is as small as 1.5kg/cm2, the power is automatically turned on to put the machine into normal water production. Prevent the pump from turning full. (The high-voltage switch automatically cuts off the power or stops the machine when the pressure tank is full or reaches the set pressure.
11. Waste water proportional device: The concentrated water is drained, and the pressure is reduced by a small hole to ensure the working pressure of the RO membrane. The ratio of concentrated water to purified water is 1:3 - 1:5. Its role is to control flow and ensure constant system pressure. When the pressure inside the membrane shell is insufficient, the drainage rate of the wastewater proportional device becomes slower. As the water in the membrane shell is full, the pressure inside the membrane shell increases, so that the source water smoothly passes through the RO membrane to achieve the water production effect; When the internal pressure is too large, the wastewater becomes faster than the drainage speed, and the pressure relief effect is achieved to protect the RO membrane.
12. Flushing the solenoid valve: It is automatically controlled by the machine (computer board). The water purifier works for 7.5 hours. The power is turned on once, and the RO membrane is flushed with high pressure and large flow. The flushing time is 1 minute and 40 seconds.
13. Pressure storage bucket: store clean water for standby, air pressure 0.4-0.8kg/cm2.
Role: reserve pure water
Empty barrel pressure: 6-8PSI
Specifications: 1.5G, 2G, 3.2G, 4G, 11G, 20G, etc.
Scope of application: ordinary household 50G, 75G, 125G, 300G, 400G and other models generally use 3.2G barrel; large capacity barrel is generally used on commercial machines
14. Ball valve on the pressure tank: the inlet or outlet valve of the pressure storage tank.
15. Post-bacteriostatic activated carbon: The odor is removed to make the water sweet and sweet, and avoid secondary pollution of the purified water in the pressure storage tank.
16, goose neck faucet: take the switch with pure water.
Second, the water purifier accessories purchase tips
1. Consumers must understand the importance of product quality when purchasing water purifiers, depending on whether there is a health permit issued by the relevant department.
2. It is very important to choose a good quality filter when installing the water purifier. The activated carbon filter is relatively easy to breed bacteria and can not achieve the clean effect. The filter element filtered by artificial polymer membrane can remove harmful substances in the water. However, it is also easy to filter out the favorable elements in the water; the nanotechnology filter element effectively filters harmful substances in the water, leaving favorable substances. So when you choose, you must choose according to your own needs.
3. According to the water quality, choose the water purifier accessories. The hardness of different waters in different areas is different, so we must choose carefully; if the water smell is strong, we should choose activated carbon household water purifier; where the water quality is seriously polluted At the time of purchase, you need to choose a fine filter water purifier.
4. Look at the after-sales service. When buying a product, you must choose a seller with perfect after-sales service. Because the water purifier will replace the filter element in the later stage, the maintenance needs to be expired, and the after-sales service is in place, the user will be more worry-free.
The choice of water purifier is very important. The choice of water purifier accessories is also very important. Therefore, consumers must pay attention to the skills of purchasing water purifier accessories.
