Working principle of large flow filter element

Does the working principle of the high-flow filter affect the maintenance method?

In the process of daily use of the high-flow filter element, some wear and tear or affect the use may occur over time, and it will be more troublesome to handle. Therefore, we must maintain the high flow filter element when we usually use it.

The main purpose of the large flow filter element is to filter the solid particles and colloidal substances in the medium, which can effectively control the degree of pollution. The design of the large diameter of the large flow filter element can increase the effective filter area and significantly reduce the number of filter elements.

In many applications, it is precisely because of the large flow and long filter life of the large flow filter that the labor cost and investment are reduced.

Maintenance methods and precautions for large flow filter elements:

1. Don't ignore worn or damaged gaskets in the housing.

If the high flow filter element is sealed. We must replace it carefully to ensure that there are no old gaskets in the casing; the seals are not worn, and do not reuse old gaskets.

2. Do not tap the large flow filter element for cleaning.

Knocking on the filter can remove dust, but the filter will also be damaged. It is enough to damage the engine by tapping on pollutants that are not too deep, so the high-flow filter element can work stably and remain safe when replaced.

3. Do not paste the large flow filter element with damaged filter paper.

Do not install recessed or raised filters because they cannot effectively prevent the entry of contaminants; recesses may cause uneven sealing or may indicate damage to the filter paper; recessed filters attached to the filter paper will consume more engine And fuel.

What are the four major performances of the high flow filter element?

There are many performances of the high-flow filter element, which are mainly reflected in four aspects in daily life and work use. These four aspects greatly affect the purpose and application field of the large-flow filter element.

Below, let us have a detailed understanding and understanding of the performance of the high flow filter element:

1. Horizontal pleating design and technology.

As the core filter unit of the high-flow filtration system, the high-flow filter adopts horizontal discount technology to enlarge the area of ??the filter medium in a limited space;

At the same time, the folding technology can ensure that when fluid passes through the filter element, each unit area of ??the filter medium has fluid passing through, ensuring that the area of ??the filter medium is completely converted into an effective filter area.

2. The flux is 20 times higher than the conventional filter element.

The flow direction is smooth outside and inside, and the inner diameter of the filter element is 3 inches, so that the high flow rate of a single filter element can reach 110 tons/hour.

3. Powerful filtration efficiency.

The high-flow filter element claims that the accuracy and filtration efficiency are 99.9% at 5μm. During the test, the filtration efficiency of the 5μm filter element is greater than 99.9%, and the filtration efficiency for 3μm particulate impurities is also over 99.5%.

4. Ultra-long life filter element.

For traditional filter elements, high filtration efficiency, high impurity holding capacity and service life often cannot find a good balance point.

That is, if the product filtration efficiency is high, its dirt holding capacity and service life may often be short;

On the contrary, due to its own technical advantages and unique design, the high-flow filter element balances the relationship between filtration efficiency, dirt holding capacity and service life, achieving a filtration efficiency of 99.9%, and a single filter element has a dirt holding capacity of up to 15KG.

Application of large flow water filter element in work

Nowadays, the emergence of large-flow water filter cartridges has solved many water filtration and water treatment problems. So how is the technology of large-flow water filter cartridges realized?

The factors and principles of large flow water filter element to achieve large flow are as follows:

The high-flow water filter element is the core filter unit of the large-flow filtration system. It adopts horizontal pleating technology and adopts precise pleating technology. The ripples are uniform. The area of ??the filter medium is larger in a limited space. The design pressure of the large-flow filter element is 80 Cubic, the actual pressure flow depends on the actual working conditions.

Corlandi high-flow filter elements include replacing pall high-flow filter elements, replacing Parker high-flow filter elements, and replacing 3m high-flow filter elements. The filtration accuracy can reach 1um (micron) and the filtration efficiency can reach more than 99.5%.

Large flow water filter

The filtration process and working principle of the large flow filter element:

When the liquid to be filtered passes through the high-flow filter element, the water in the inlet pipe enters the filter through the drainage channel, then passes through the support layer from top to bottom, is collected by the water distribution system, and is discharged through the outlet pipe.

After filtering for a period of time, the amount of suspended matter remaining in the filter layer increases, and the porosity of the filter layer decreases, thereby increasing the flow of pore water.

On the one hand, the filtration resistance increases. On the other hand, the impurities in the pores are washed away by the water flow, the pressure increases, and the water quality deteriorates. When the head loss exceeds the allowable value, or when the concentration of suspended solids in the effluent exceeds the specified value, the filtration and reaction The flushing of the filter should be terminated.

Performance measurement method of PP folded filter element microfiltration membrane

The performance of the PP pleated filter element microfiltration membrane needs to be measured. The measurement method mainly starts from four aspects, which are membrane defects, membrane thickness, membrane apparent density and porosity.

1. Determination of membrane defects.

Film defect refers to the existence of holes in the surface or deep layer of the film, and their existence has a direct impact on the performance of the film. Therefore, the defective film should be removed before use.

Defective membranes can generally be inspected visually or with the aid of a microscope, and can also be measured by immersing them in water (or non-solvent of the membrane) by bubbling.

2. Measurement of film thickness.

It is generally measured by a spiral micrometer or thickness gauge, and it can also be visually measured under a microscope or electron microscope.

3. Determination of apparent density of film.

Generally, a weighing method is used to first weigh the mass of the film, and then calculate the volume based on the measured film thickness and inner and outer diameter data. The ratio of the two is considered to be the apparent density of the film.

4. Determination of porosity.
