7 stage reverse osmosis system Household water channel

The principle process of water passage of the machine:

The pressure of raw water must be greater than 0.2Kg/cm2 because of

 a spare part in the pure water machine. If the pressure is lower than this,

 the pure water machine will not start the water. The raw water enters the

 pure water machine through the inlet three ways. There is a 2 points 

(3 points) on the inlet tee small ball valve - inlet ball valve, its main role 

is: in the water water machine water leakage or pure water machine waste

 water flow does not stop under the situation cut off the raw water source 

of pure water machine, waiting for professional technical personnel to deal with.

Through the inlet ball valve after you came to the first level of pure water 

machine filter - PPF, its diameter is 5 microns, can filter out the sediment in 

the water, rust, colloid, and greater than 5 micron particulate impurities, it is

 the main raw material for polypropylene, by high temperature dissolving, wire

 drawing and winding, formed by replacement of life between 3 to 6 months,

 according to the local water quality. We have just started to say why the water 

pressure must be greater than 0.2 Kg/cm2 because after the water electromagnetic 

valve through a electrical components, low voltage switch, it under normal

 circumstances is in a state of closed for a long time, but when the raw water pressure

 is less than 0.2 Kg/cm2 and under the condition of water, it will disconnect the circuit

 system of pure water machine disconnect, prevent the back of the idle high-pressure

 pump. After the low pressure switch to the inlet solenoid valve, its internal is made of

 copper wire wound, in the moment of electrification formed electromagnet will be metal 

plug suction to make the water channel smooth, pure water machine power after magnetic 

disappear, the metal plug will fall again to cut off the water channel.
