Small Pressure Difference Security Filter

The small pressure difference security filter, also known as the precision filter, uses the formed filter material. The main function is to remove fine particles in the liquid to meet the requirements of the subsequent process for water inlet. While the liquid passes through the filter material under pressure, the filter residue remains on the pipe wall, and the liquid flows out through the filter material to achieve the purpose of filtration.

Structure and composition

1. Cylinder

The cylinder of the security filter is usually made of high-quality stainless steel, which is durable and has good corrosion resistance, and can adapt to the requirements of different working environments.

2. Filter element

The filter element is the core component of the security filter. Common filter types include meltblown filter element, wire wound filter element, folding filter element, etc. These filter elements have different filtration accuracy and characteristics and can be selected according to actual application requirements.

3. Inlet and outlet pipelines

The inlet and outlet pipelines ensure that fluids can enter and exit the filter smoothly, ensuring the continuity of the filtration process.

4. Sewage outlet

The sewage outlet is used to regularly discharge the accumulated impurities and contaminants in the filter to maintain the good performance of the filter.

Working principle of the security filter

The working principle of the small pressure difference security filter is based on a precise filtration mechanism. When the liquid passes through the filter element, the micropores or gaps in the filter element block the impurity particles larger than its pore size, thus achieving the purification of the liquid. As the filtration proceeds, impurities will gradually accumulate on the surface of the filter element, causing the pressure difference of the filter to increase. When the pressure difference reaches a certain level, the filter element needs to be cleaned or replaced.

Application

1. Water treatment industry

In the water treatment process, security filters are often used for pre-filtration of membrane treatment systems such as reverse osmosis, ultrafiltration, and nanofiltration to effectively remove impurities such as suspended solids, colloids, and particulate matter in water and protect the normal operation of subsequent membrane components.

2. Electronics industry

The electronics industry has extremely high water quality requirements, and security filters can provide high-purity water to meet the needs of semiconductor manufacturing, integrated circuit production, and other fields.

3. Food and beverage industry

It is used for the filtration of fruit juices, beverages, alcohol and other products to remove impurities and microorganisms to ensure the quality and safety of the products.

4. Pharmaceutical industry

In the pharmaceutical production process, security filters can be used to filter pharmaceutical liquids, extracts, etc., to ensure the purity and quality of pharmaceutical products.

5. Chemical industry

It can filter chemical raw materials and products, remove impurities, and improve the efficiency and product quality of chemical production.

Parameters

Performance characteristics

1. High filtration accuracy

It can effectively remove tiny impurity particles, ensuring that the filtered fluid reaches a high purity.

2. Small pressure difference

Reasonable structural design makes the pressure difference smaller when the fluid passes through, reducing energy loss.

3. Large traffic

It can meet the demand for large flow rate fluid filtration and improve production efficiency.

4. Strong corrosion resistance

Adapt to the filtration of a variety of corrosive media, ensuring the long-term stable operation of the equipment.

5. Long service life

The high-quality filter element and barrel material ensure that the security filter has a long service life.

Maintenance

1. Regularly check the contamination of the filter element and clean or replace it in a timely manner.

2. Keep the filter clean and regularly clean the impurities in the cylinder and pipes.

3. Check whether there are any leaks in the inlet and outlet pipelines and connection parts, and repair them in time.

4. Perform regular maintenance and maintenance according to equipment requirements, and record relevant data.

FAQ

1. Q: What is the function of a filter?

A: The main function of a filter is to remove solid particles, impurities, and harmful substances from liquids or gases, in order to achieve purification, clarification, and protection of equipment.

2. Q: How to choose a suitable filter?

A: When choosing a filter, factors such as the properties of the material being filtered (e.g., viscosity, temperature, corrosion), required filtration accuracy, processing capacity, operating pressure and medium, as well as the type, material, size, and installation method of the filter should be considered.

3. Q: What is the working principle of a filter?

A: The working principle of a filter mainly relies on physical screening, deep interception, absorption, or chemical reactions to remove impurities or harmful components from the material being filtered.

4. Q: How to maintain and care for a filter?

A: Maintenance of filters includes regular cleaning or replacement of filter elements, inspection of seals and fasteners, maintaining stable operating pressure, and avoiding overloading. Specific methods should be referenced from the filter's instruction manual and maintenance guides.

5. Q: What is the service life of a filter?

A: The service life of a filter depends on its working environment, processing volume, and filtration accuracy. Generally, when the filter's pressure drop reaches a certain value or the filtration effect decreases significantly, it needs to be replaced or cleaned.

6. Q: What should be paid attention to during filter installation?

A: During filter installation, attention should be paid to the directionality, ensuring that the fluid enters and exits from the correct ports. Also, the piping system should be cleaned before installation, and the filter should be securely fastened and sealed as required by the instructions.

7. Q: What is the replacement cycle for filters?

A: The replacement cycle for filters depends on their working conditions and filtration requirements, and is usually indicated by pressure difference indicators or timers. When the filter's pressure drop reaches the set value or the filtration effect decreases, it should be replaced in a timely manner.
