INTRODUCTION

The central rod plays a crucial role in stably supporting the entire filter cartridge, ensuring that it can maintain a stable state during the filtration process. Materials like polypropylene and stainless steel are available for the central rod to meet different working condition requirements. The end caps are located at both ends of the filter cartridge. On the one hand, they provide good protection for the filter materials. On the other hand, they facilitate the tight and sealed connection and installation of the filter cartridge with various filtration equipment. The materials are often plastic or metal, ensuring overall sealing and adaptability. With such a structure, wire-wound filter cartridges can effectively intercept impurities in numerous fluids and play an important role in the filtration systems of various industries. Moreover, they come in a rich variety of specifications and can be flexibly selected according to needs.

WORKING PRINCIPLE

Wire-wound filter cartridges rely on the basic filtration principle of physical interception. When liquids or gases containing impurities flow through the filter cartridges, since the filter materials are formed by fibers wound according to specific rules, there are numerous tiny pores among the fibers. These pores are just like tiny "sieves". Impurity particles with particle sizes larger than the pore sizes cannot pass through smoothly and will be blocked on the surface of the filter materials or in the gaps between the fibers. However, components with particle sizes smaller than the pore sizes, such as water molecules and gas molecules, can pass through the filter cartridges along the pores, achieving effective filtration of impurities in the fluids and thus realizing the goal of fluid purification.

PRODUCT FEATURES

l High Filtration Precision: By carefully selecting filter materials and precisely controlling the tightness of fiber winding and other factors, wire-wound filter cartridges can achieve multi-level filtration precision ranging from coarse filtration to fine filtration. They can accurately capture tiny suspended substances, particulate impurities, etc., perfectly meeting the application scenarios with strict requirements for filtration precision. For example, they can remove extremely tiny impurities in the preparation of ultrapure water in the electronics industry.

l Strong Dirt-Holding Capacity: The fiber structure of the filter materials endows them with a relatively large specific surface area. The numerous fiber gaps can accommodate a large amount of impurities. During long-term filtration operations, they can continuously intercept impurities, effectively delaying the occurrence of filter cartridge clogging, prolonging the service life of the filter cartridges, reducing the frequency of filter cartridge replacement, and thus reducing the use cost.

l Stable and Reliable Structure: The central rod provides solid support, and combined with the sealing and fixing functions of the end caps, the entire filter cartridge can still maintain its structural integrity under different working pressures and temperature environments. It is not prone to deformation, loosening, and other problems and can stably perform its filtration functions.

l Good Chemical Compatibility: Whether it is glass fiber, absorbent cotton fiber, or the matching polypropylene, stainless steel and other materials, the filter cartridges show good tolerance to a variety of chemical substances. They can work normally in a wide range of acidity and alkalinity and different chemical environments and can be widely used in the filtration of various fluids.

TECHNICAL PARAMETERS

l Applicable pH Range: Wire-wound filter cartridges can adapt to a pH range of 1 - 13, which means they have good tolerance in fluid environments with various chemical properties such as acidic and alkaline ones and can cope with relatively complex filtration working conditions.

l Working Pressure: When a polypropylene skeleton is adopted, the working pressure can generally reach 0.6 MPa. If a stainless steel skeleton is selected, the working pressure can reach 0.8 MPa. Such pressure parameters ensure that the filter cartridges can work stably under different fluid pressure environments and meet diverse filtration needs.

l Working Temperature: The working temperature that glass fiber wire-wound filter cartridges can adapt to can reach 90 °C. The corresponding working temperature for absorbent cotton fiber wire-wound filter cartridges can reach 120 °C. The working temperature for other common materials is usually 90 °C as well. This enables them to reliably perform their filtration duties within the corresponding temperature ranges and be suitable for filtration scenarios with different temperature requirements.

l Filter Cartridge Length: Common filter cartridge length specifications include 10 inches (approximately 254 mm), 20 inches (approximately 508 mm), 30 inches (approximately 762 mm), and 40 inches (approximately 1016 mm). Users can flexibly choose according to the specific size of the filter and the actual treatment flow rate and other actual situations to adapt to different scales of filtration devices.

l Filter Cartridge Diameter: The diameter of most filter cartridges on the market is 65 mm. Of course, filter cartridges with different diameters can also be selected according to actual needs so that they can be perfectly matched with various filtration equipment ranging from small experimental devices to large industrial filtration systems to meet the needs of diverse application scenarios.

APPLICATION FIELDS

l Water Treatment Industry: In the pretreatment process of municipal water supply, wire-wound filter cartridges can intercept large-particle impurities such as sediment and rust in water, reducing the burden on subsequent deep treatment equipment. In industrial circulating water systems, they can remove suspended substances, microorganisms, etc. in water, preventing pipe scaling and corrosion and ensuring the stable operation of the systems. Meanwhile, in the front end of membrane separation processes such as reverse osmosis and ultrafiltration, as protective filter cartridges, they can effectively extend the service life of expensive membrane components.

l Pharmaceutical Industry: The pharmaceutical production process has extremely high requirements for water quality. Whether it is water for drug preparation or water for cleaning medical devices, wire-wound filter cartridges can achieve fine filtration to remove impurities such as bacteria and particles in water, ensuring that the purity of water meets the strict Good Manufacturing Practice (GMP) requirements for pharmaceutical production, safeguarding drug quality and medical safety.

l Food and Beverage Industry: In processes such as raw water filtration in beverage production and water purification for cleaning in food processing, wire-wound filter cartridges can remove impurities in water that may affect taste and product quality, ensuring that the produced food and beverage products meet hygiene standards and taste requirements and enhancing the product quality and market competitiveness.

l Electronics Industry: In processes such as electronic chip manufacturing and printed circuit board production, ultrapure water is an essential raw material. Wire-wound filter cartridges, relying on their high filtration precision, can intercept tiny particles, organic substances and other impurities in water, providing high-quality ultrapure water for the electronics industry and avoiding adverse effects of impurities on the performance of electronic components, ensuring the quality and stability of electronic products.

SUMMARY

Wire-wound filter cartridges, with their unique structure, reliable filtration principle, numerous excellent features, and reasonable and adaptable technical parameters, have shown indispensable value in multiple key fields such as water treatment, pharmaceuticals, food and beverage, and electronics. They are like the outstanding gatekeepers in the filtration field, quietly contributing to ensuring the purity of fluids, improving product quality, and promoting the sustainable development of various industries. With the continuous progress of science and technology, it is believed that wire-wound filter cartridges will continue to make breakthroughs in aspects such as improving filtration precision, optimizing material performance, and expanding applications, further meeting the increasingly diverse filtration needs of society and becoming an important supporting element for creating a high-quality production and living environment.
