Water Filter Purifier Faucet Principle

- Jul 18, 2018 -

The filter faucet has more filter function than the ordinary faucet, so here we first introduce the principle of the filter. The water to be treated by the filter enters the body through the water inlet, and impurities in the water are deposited on the stainless steel filter screen, thereby generating a pressure difference. The differential pressure switch monitors the pressure difference between the inlet and outlet. When the differential pressure reaches the set value, the electric controller supplies the hydraulic control valve to drive the motor signal. After the equipment is installed, the technician will debug and set the filtration time and cleaning conversion time. The water to be treated enters the body through the water inlet, and the filter starts to work normally. When the preset cleaning time is reached, the electric controller gives the hydraulic control valve. Driving the motor signal, triggering the following actions: the motor drives the brush to rotate, and the filter element is cleaned. At the same time, the control valve is opened for sewage discharge. The entire cleaning process only lasts for several tens of seconds. When the cleaning is finished, the control valve is closed and the motor stops rotating. The system returns to its initial state and begins the next filtration process. The inside of the filter casing is mainly composed of a coarse filter mesh, a fine filter mesh, a suction pipe, a stainless steel brush or a stainless steel nozzle, a sealing ring, an anti-corrosion coating, a rotating shaft and the like.

Separating the container into upper and lower chambers with a filter medium constitutes a simple filter. The suspension is added to the upper chamber and enters the lower chamber through the filter medium under pressure to form a filtrate, and the solid particles are trapped on the surface of the filter medium to form a filter residue (or filter cake). During the filtration process, the filter residue layer on the surface area of the filter medium is gradually thickened, and the resistance of the liquid passing through the filter residue layer is increased, and the filtration speed is reduced. When the filter chamber is filled with filter residue or the filtration speed is too small, the filtration is stopped, the filter residue is removed, and the filter medium is regenerated to complete a filtration cycle.

The liquid must pass through the filter cake layer and the filter medium to overcome the resistance, so there must be a pressure difference on both sides of the filter medium, which is the driving force for the filtration. Increasing the pressure difference can accelerate the filtration, but the particles deformed after being pressed are likely to block the pores of the filter medium when the pressure is large, and the filtration is slowed down.

The suspension is filtered by three methods: filter layer filtration, depth filtration and sieve filtration.

1 Filter layer filtration: In the initial stage of filtration, the filter medium can only retain large solid particles, and the small particles pass through the filter medium with the filtrate. After the formation of the initial filter cake layer, the filter residue layer plays a major role in the filtration, at which time both large and small particles are trapped, such as filtration by a plate and frame filter press.

2Deep filtration: The filter medium is thicker, the suspension contains less solid particles, and the particles are smaller than the pores of the filter medium. When filtering, the particles are adsorbed in the pores after entering, such as filtration of a porous plastic tube filter or a sand filter.

3 Screening: The solid particles intercepted by the filtration are larger than the pores of the filter medium, and the inside of the filter medium does not adsorb solid particles, for example, the rotary filter screen filters out coarse impurities in the sewage. In the actual filtration process, the three methods often occur simultaneously or sequentially.


What should I do if the water filter purifier faucet  leaks?

What should I do if the filter faucet leaks? How to repair the problem of different parts?  Water Filter Purifier Faucet as a kind of faucet, the maintenance method is as follows:

1. Change the axis of the faucet

Knowing ourselves and knowing each other can be a battle, and the faucet is the same. If you want to leak the faucet, you need to know the reason why the faucet leaks. If the shaft pad in the faucet is worn out, then use the pliers to loosen the gland bolt, then take out the shaft gasket and replace it with a new one. Enough!

2, the water stop tape is damaged

Tighten the faucet and then use a wrench to remove the faucet counterclockwise. Then use a threaded hole to wind the tape back six times in a clockwise manner. After making it, re-tighten the faucet and then open the switch. There will be no water leakage.

3, the faucet takes over the joint leakage

Remove the cap nut from the faucet and retighten it or replace it with a new u-ring.

In addition, it is judged that there is water leakage in your faucet. You can understand by observing the water output of the faucet. Generally, if the faucet leaks more and more, the water output of the faucet will become larger and larger.


Filter faucet installation

Because kitchen faucets are used more frequently, they are required to be stable. In addition, it is moved and moved, it is easy to loose, so the lock nut must be tightened. At present, some faucets appear on the market for the screw to increase the nut fixing. This kind of stability effect is very good. If it can solve the problem of water removal, it will be a popular trend in the future.

The single cold that is mounted on the stainless steel basin is fixed only after the two ends of the four-part hose. One end is attached to the angle valve. One end is connected to the bottom of the faucet. The heat and the like are similar.

There are several types of faucets: there are single cold, mixed with hot and cold. Single cold is very simple, directly installed on the wall of the water pipe head, if it is mixed with hot and cold, it should be clear about the hot and cold water on the wall, usually left hot right cold.

Nowadays, the faucet is still very particular. For example, if you want to cook a child at home, the faucet should be lower. So that the water does not wet the clothes along the sleeves of the clothes.
