Why change the filter?
filter (filter) is an indispensable device on the transmission medium pipeline, usually installed in the pressure reducing valve, pressure relief valve, fixed level valve. The filter has a filter cartridge of a certain size filter screen, and its impurities are blocked, and when it needs to be cleaned, as long as the detachable filter cartridge is removed and re-loaded after treatment.
Daaaaaa!
If the core of the early filter is not cleaned and replaced in time, the ability of the filter to effectively filter harmful substances will be greatly reduced in the early stage, when the output of water exceeds the rating of the effective filter, after the water starts, these substances in the water will not only not be adsorbed, but also be released from the filter to the water. The beginning of this primary filter not only has a lower effect than clean water, but even causes minor pollution.
Basic performance characteristics of the filter:
1. Efficient and accurate filtration: the special structure of the filter disc filtration technology, accurate and sensitive performance, only particles smaller than the required size can enter the system, is an effective filtration system; Specifications are 5μ, 10μ, 20μ, 55μ, 100μ, 130μ, 200μand so on, the system flow can be flexibly adjusted according to needs.
2. Standard modular, saving land: The system is based on the standard disk type filter unit, according to the modular design, users can choose according to demand, flexible and changeable, strong interchangeability. The compact system has a very small footprint and allows flexible installation using corner space.
3. Fully automatic operation, continuous water discharge: between the units in the filter combination, the backwashing process takes turns; Automatic switching between working and backwashing states ensures continuous water discharge; Backwash water consumption is very small, accounting for only 0.5% of the water output; If combined with air assisted backwashing, the water consumption can be reduced to less than 0.2%. High-speed and thorough backwashing takes only tens of seconds to complete.
4. Long life: the new plastic filter element is strong, no wear, no corrosion, very little scaling, after many years of industrial practical verification, the use of 6 to 10 years without wear, no aging, filtration and backwashing effect will not deteriorate due to the use of time.
5. High quality, less maintenance: the products meet the corresponding quality standards, all products are tested and tested by simulated conditions before leaving the factory, no special tools are required, few parts; Easy to use and requires little maintenance.

How the filter works
picture
The water to be treated by the filter enters the body by the water inlet, and the impurities in the water are deposited on the stainless steel filter screen, resulting in a pressure difference.
Filter outlet pressure difference changes, when the pressure difference reaches the set value, the electric controller gives the hydraulic control valve, drives the motor signal, and causes the following actions: the motor drives the brush to rotate and cleans the filter element; At the same time, the control valve is opened for sewage discharge, the whole cleaning process only lasts for tens of seconds, when the cleaning is finished, the control valve is closed, the motor stops rotating, the system returns to its initial state, and the next filtration process begins.
After the equipment is installed, the technical personnel will debug, set the filtration time and cleaning conversion time, the water to be treated enters the body from the water inlet, the filter begins to work normally, when the preset cleaning time is reached, the electric controller gives the hydraulic control valve and drive motor signals, triggering the following actions: The motor drives the brush to rotate, cleaning the filter element, while the control valve is opened for sewage discharge, the whole cleaning process only needs to last tens of seconds, when the cleaning is finished, the control valve is closed, the motor stops rotating, the system returns to its initial state, and begins to enter the next filtration process.
The shell of the filter is mainly composed of coarse filter screen, fine filter screen, suction pipe, stainless steel brush or stainless steel nozzle, sealing ring, anti-corrosion coating, rotating shaft and other parts.

Product classification of filters
Self-cleaning filter is a kind of precision equipment that uses the filter screen to directly intercept impurities in the water, remove suspended matter and particulate matter in the water body, reduce turbidity, purify water quality, reduce system dirt, bacteria, algae, rust, etc., in order to purify water quality and protect the normal work of other equipment in the system.
The automatic filter is a set of equipment widely used in the filtration industry, which overcomes the shortcomings of traditional filtration products such as small amount of pollution, easy to be blocked by dirt, the filter part needs to be disassembled and cleaned, and the filter status cannot be monitored. It has the function of filtering raw water and automatically cleaning the filter element.
The biggest advantage of the elastic filter is that it is maintenance-free and can be cleaned automatically, avoiding the hidden danger of clogging caused by the long-term work of the filter element. Features: maintenance-free, automatic cleaning, short cleaning time (3 seconds). When cleaning, the spring opening gap is equal and can swing, which can replace the net type, cylinder type, bag type and other filters to reduce the comprehensive cost.
The prototype of the Air Filter is a respiratory protection device used by people to protect their breathing. It is recorded that as early as the first century in Rome, people used masks made of coarse hemp to protect themselves while purifying mercury. In the long time since then, air filters have also made progress, but they are mainly used as respiratory protection devices in some dangerous industries, such as the production of harmful chemicals. In 1827, Brown discovered the motion law of tiny particles, and people had a further understanding of the mechanism of air filtration.
The liquid filter enables the contaminated liquid to be cleaned to the state required for production and life, that is, to make the liquid reach a certain degree of cleanliness.
Internet filters, which are set up to block spam, make the information on the computer screen as consistent as possible.
The light filter, with the principle of absorption, separates the light of different colors and absorbs some unwanted light.
