Installation requirements for self cleaning filters, how to clean the filter

The selection of filter specifications should be matched with the installation pipeline, when the filter flow can not meet the requirements of the pipeline, two (or more) filters can be installed in parallel, or side filtration treatment.

The filter should be installed as far as possible in the place where the system is to be protected, and the low pressure at the inlet affects the use, so it should also be installed close to the pressure source.

The filter should be installed in series in the pipeline system, in order to ensure the uninterrupted water supply of the system when the system is shut down for maintenance, it is recommended to set up a bypass in the system, and the filter inlet and outlet and the bypass should be provided with a shut-off ball valve. Where backflow is likely to occur, a check valve should be installed at the filter outlet.

When selecting the filter, pay attention to the water temperature flowing through the automatic self-cleaning filter does not exceed its suitable temperature.

The installation site is equipped with three-phase 380V power frequency alternating current (three-phase four-wire system). The sewage pipe should not exceed 5 meters to avoid back pressure.

The DC system should pay attention to the filtration accuracy, pretreatment, and pressure matters, and the intermittent system should pay attention to the timing control type.

Reasonably choose the installation environment, pay attention to waterproof, rainproof and moisture-proof.

Valves should be installed at the water inlet, outlet and sewage outlet of the equipment (the sewage valve should be a fast valve).

The net distance between the equipment is not less than 1500mm; The net distance between the equipment and the wall is not less than 1000mm; The equipment and the surrounding area should be set aside not less than 500mm of maintenance space.

On the inlet and outlet pipelines of the equipment, pipe supports should be set close to the nozzle; Brackets should be set under valves greater than or equal to DN150 that are directly connected to the nozzle of the container.

1.In most applications, the filter should be installed as close to the system as possible, but low pressure at the filter inlet during flushing is a very problematic issue, so the filter should also be installed closest to the pressure source.

2.Confirm that the system pressure is not lower than during the filter backwash.

3.When the filter needs to be maintained and the water supply cannot be interrupted, valves should be installed at the inlet and outlet of the filter, and bypass valves should be installed between the inlet and outlet.

4.Make sure that the pressure source is the same as the filter inlet diameter.

5.As a minimum requirement for filter installation, a valve is installed at the outlet of the filter to allow the filter to be troubleshooting.

6.Where backflow is likely to occur, a check valve is also installed at the filter outlet.

7.Verify that the filter flow direction is consistent with the system flow direction.

8.Confirm that there is sufficient maintenance space to allow internal components to be extracted.

9.Verify that the flushometer is properly installed as shown in the aiger installation diagram.

The self-cleaning filter is a device that uses a filter screen to intercept impurities in the water, which can remove suspended solids, particulate matter and other impurities in the water, so as to reduce the turbidity of the water body, purify the water quality, and reduce the generation of system dirt and bacteria. The water to be purified enters the body of the self-cleaning filter from the water inlet, and after intelligent identification, the system can know the degree of impurity deposition, and when the degree of impurity deposition reaches the preset value, the system will automatically discharge the sewage valve signal.

Installation Instructions:1The device body is installed.

When installing, pay attention to the protection of the control box, sensor and transmission part to prevent it from being damaged and causing the equipment to run abnormally.

2.Pay attention to make the outlet direction of the automatic blowdown valve horizontal or downward to ensure that the blowdown is more thorough.

3.The filter should be installed in front of the water appliance to be protected and as close to the water appliance as possible.

4.In the power system, the YS automatic should be installed between the pump and the water equipment, the closer to the water equipment, the better. When the pressure before the pump and the water device exceeds the limit pressure of the filter, the filter can also be installed in front of the pump and as close to the pump as possible.

5.The connection mode of the automatic sewage valve is divided into flange and thread, and the sewage pipe should not be too long, preferably not more than 10 meters.

6.The installation should be considered for easy maintenance, and shut-off valves should be installed before and after the filter, and bypass pipes should be installed.

First of all, clean the filter material, filter cotton, etc. should be cleaned in the raw water of the fish tank, that is, the water from the fish tank will be cleaned, if you use tap water, etc., the nitrifying bacteria will be destroyed, the tube of the external filter barrel is relatively long, you can go to ** buy the kind of brush that specializes in brushing the pipe, it is very long and very easy to use, and the filter can be cleaned once every half a month to a month.

Answer: The flushing process of the 3m pre-filter is completed by the cleaning brush and the blowdown valve that rotate along the inner surface of the filter cartridge, and the open blowdown valve makes the blocked filter cartridge form a negative pressure, and the filter cake attached to the inner wall of the filter cartridge is cleaned by the cleaning brush and discharged outside the body due to the negative pressure. The entire cleaning process takes about 60 seconds, and the system is constantly flowing during cleaning. The process is as follows:

2.Insert a slotted screwdriver from the spout (marked "out") into the black lid as a gripper for your left hand. Use a wrench in your right hand to unscrew the white quick coupling at the prefilter outlet (marked "out").

4.Remove the old water purifier cartridge and carefully clean the inside of the filter bottle and the cap of the filter bottle. Insert a new filter cartridge of the same specification, screw the black cap on, and further tighten the filter flask by rotating the handle of the special wrench to the outside of the body as in step 5.

Then tighten the white quick coupling with a wrench.

6.Place the pre-filter vertically and adjust the position, open the three-way ball valve for water inlet, then open the non-pressure faucet, and after a few minutes of water discharge, check the connections of the machine to ensure that there is no water leakage and can be used normally.

That's it for the 3M pre-filter flushing process.

It depends on what type of filter, filter type or filter bag type, generally after replacing the filter bag of the filter element, first clean it with water, and there is still residue, you need to determine what metal it is, and generally soak it in vinegar.

How to clean the filter of the washing machine?

1) Clean the air filter. Loosen the filter latch, remove the nut holding the filter in place, remove the cover and pull out the filter. Take out the filter element and take care to prevent impurities from falling into the carburetor. Wipe the inside and outside of the air filter case with a cloth dipped in gasoline.

Check the extent of contamination of the filter element and clean it. When the filter element accumulates dry dust, compressed air with a pressure of no more than 500kPa can be used to blow the dust on the inner and outer surfaces of the filter element evenly along the bevel direction from the inside of the filter element. If compressed air is not available, use the screwdriver handle to gently tap the filter and use a brush to clean the external dirt.

When operating, do not hit or bump the filter element with great force. During cleaning, if the filter element is found to be damaged, the filter element should be replaced. Normally used paper filters should be replaced at specified intervals.

2) Check the filter cartridge after cleaning and drying. Illuminate the light and put the inside of the filter element to observe whether there is damage, small holes, or thinning parts, and check whether the rubber gasket is damaged. If there is an abnormality, the filter element and gasket should be replaced.

3) Replace the filter element of the air filter. Replacement will be carried out according to the regulations of each model. When replacing the filter element, attention should be paid to check whether the new filter element is damaged, whether the gasket is defective, and if any defects are found, it should be matched.

4) Install an air filter. After the filter cartridge is cleaned, install the parts in the reverse order from disassembly. The filter must be reliably installed, and the paper part of the filter must not be touched by hand or utensils, especially not to allow oil to contaminate the filter.

When the inlet pipe is installed, it should be ensured to be sealed, and special attention should be paid to the sealing of the sheath of the inlet joint.

When maintaining the air filter, you should also carefully check the condition of the hose to which the air filter is attached, and replace the hose if it is found to be cracked or deteriorated.

Automobile engines are very delicate parts, and the smallest impurities can damage the engine. Therefore, before the air enters the cylinder, it must be finely filtered by the air filter before it can enter the cylinder. The air filter is the patron saint of the engine, and the quality of the air filter is related to the life of the engine.

If a dirty air filter is used in the car, the engine will be under-intake, so that the fuel combustion is incomplete, resulting in unstable engine work, power decrease, and fuel consumption increases. Therefore, it is essential for the car to keep the air filter clean.

Under normal road conditions, the air filter must be cleaned and maintained when the car travels 7500-8000km. In areas with a high degree of sand and dust, the interval between maintenance should be shortened accordingly.

Dry air filters are widely used in new cars, and the filter element of the dry air filter is made of microporous filter paper treated with resin, which has the characteristics of good filtration effect and easy maintenance. Depending on the model, the structure and shape are different, but the maintenance method is basically the same. When maintaining it, it should be carried out in accordance with the mileage specified by the automobile manufacturer.

Give points

The method of disassembling and cleaning the filter is:1. Shut down the filter and remove the manhole cover. Unscrew the hold-down nut of the filter element, remove the pressure plate, take out the filter element, and rinse the inside of the device with water.

2. Remove the upper and lower positioning rings at both ends of the filter element and clean them with water.

3. Insert one end of the retaining ring under the cleaned filter element into the hole of the multi-well plate.

4. Take the tie rod as the axis, insert the pressing plate, insert the upper positioning ring of the filter element into the corresponding pressing plate hole, and tighten the compression nut.

5. After the filter element is installed, install the manhole cover plate and turn on the machine for water.

6. Open the water inlet valve and exhaust valve, when the water is full of equipment, open the net valve, close the exhaust valve, observe the water outlet of the net port, and after the water is free of white foam, it can be used normally after cleaning.

Filter Cleaning Method:1.Separate the upper and lower sections of the filter and use a clean, unbrushed new toothbrush to brush the surface of the filter while rinsing the upper filter (ceramic) with clean tap water.

2.When the upper filter element is filled with about half a pot of tap water, shake the filter element up and down several times, pour out the remaining water, and reciprocate several times to make the micropores of the filter element unblocked, fill the lower filter element with tap water, and pat the mouth flat up and down with the palm of your hand to make the lower filter element shake, and make the tap water clean the filter material. This is repeated several times until the tap water coming out of the lower filter is clear.

3.It is to clean the diet and heat the cooling chamber, put clean water, and then repeat the rinse several times without any problem.

1. The pre-filter is a very important part of the water purifier. Cleaning the pre-filter is actually very simple, the first step is to close the main valve first, and then open the blowdown valve to let the water in the filter bottle completely drain.

2. Then use an adjustable wrench to jam the adjustable wrench at the bottom of the filter bottle, wring out the filter bottle, and remove the filter element by hand.

3. Clean the filter bottle and filter element that you just removed, wash it with water, and dry it to achieve dryness, but remember that it can no longer be exposed to the sun, it must be dried in a cool place.

4. Install the cleaned filter bottle and filter element again in the initial state, be sure to tighten it, otherwise it will leak during use, and then open the main valve to observe whether there is water leakage, if there is no water leakage, the installation is correct and the installation is completed.

How to clean the filter of the washing machine?

General principles for the selection of self-cleaning filters.

1. Import and export diameter:

In principle, the inlet and outlet diameter of the filter should not be smaller than the inlet diameter of the matching pump, which is generally consistent with the diameter of the inlet pipeline.

2. Nominal pressure:

The pressure level of the filter is determined according to the highest possible pressure of the filter line difference.

3. Selection of the number of meshes:

The main consideration is the impurity particle size of the hall ridge that needs to be intercepted, which is determined according to the process requirements of the media process. The particle size that can be intercepted by various specifications of wire mesh can be found in the following table "Filter Specifications".

4. Filter material:

The material of the filter is generally the same as the material of the connected process pipe, and the filter made of cast iron, carbon steel, low alloy steel or stainless steel can be considered for different service conditions.

5. Calculation of filter resistance loss:

For water filters, the pressure loss is as follows:

1.The first is that when operating a self-cleaning filter, the equipment must be operated according to the correct procedures. There are a lot of different filters on the market, and although the operation process of each device is similar, you should still read the instruction manual before using it, paying attention to certain details, which will better help you operate the device.

2.It is the professional operation of professionals. Equipment such as washable filters are more specialized equipment and usually require professional operators to operate, especially those working in the workshop, learning to operate the filter correctly is not only related to work efficiency, but also related to the use of equipment.

3.Pay attention to equipment maintenance and training. After using the device for a while, there may be some minor issues. It is necessary for us to do some regular maintenance and upkeep on the equipment regularly to prolong the service life of the equipment.

4.Self-cleaning filters must be maintained. During the overhaul, sometimes we can check some big or small problems in the equipment.

If there is a problem with the equipment, we must solve it in time. Therefore, it is recommended that all staff inspect the washable filters every three months to six months to ensure that there are no problems with the equipment.
