What is a sintered metal powder filter?

A sintered metal powder filter is a high-performance purification part made from metal powder without the enhancement of binders. It is manufactured via chilly isostatic pressing and high-temperature vacuum cleaner sintering. By adjusting the bit size of the metal powder and process criteria, the pore size and distribution can be flexibly changed to fulfill the filtering requirements of various applications. Its filtration principle is based upon micron-level precision interception. When fluid streams via the filter component, solid bit impurities are blocked externally to form a filter cake, allowing pure fluid to pass through efficiently. This brings back contaminated liquid to the sanitation needed for production, ensuring the purity of downstream products while shielding tools from damage.

Compared to non-metallic filter cartridges, it can be backwashed or reverse-blown cleaned up due to its high stamina, permitting reuse after removing the filter cake, considerably expanding its life-span and reducing costs. In addition, it possesses exceptional residential properties such as high-temperature resistance, deterioration resistance, influence resistance, and great permeability. In sectors such as petrochemicals, pharmaceuticals, food and drinks, and water therapy, sintered steel powder filter cartridges play a vital function, supplying dependable purification for fluids and gases.

How is the Sintered Steel Powder Filter Prodcution Process?

Sintered metal powder filter are made from metal powder as raw material, without the need for binders during manufacturing, ensuring the pureness and efficiency stability of the filter elements from the resource.

The production procedure is well-defined: first, the product is shaped via cool isostatic pressing, followed by high-temperature vacuum sintering to make certain the structural honesty of the filter aspects.

By appropriately picking the dimension of steel powder bits and changing process criteria, the pore dimension and circulation of the element can be flexibly gotten used to fulfill various filtering requirements.

In addition, by leveraging the attributes of various filtration products in regards to pore structure, product composition, and pressure resistance, purification items tailored to specific user requirements can be established.

How is the Filtration Principle of Sintered Metal Powder Filter?

Sintered metal powder filter elements achieve micron-level precision filtration, effectively separating solid particle impurities from liquids and gases.
When fluid flows through a filter element of a certain precision, impurities are blocked on the filter surface, gradually forming a filter cake.
Pure fluid then flows through the filter element, bringing the originally contaminated or impure fluid to the cleanliness required for normal production.
This process not only ensures that downstream equipment receives pure products but also protects equipment from malfunction.

Backwashing Advantages of Sintered Metal Powder Filter Cartridges

Unlike non-metallic sintered filter cartridges, sintered metal powder filter cartridges feature high strength.
When the filter cake on the cartridge surface reaches a certain thickness, this property allows it to be processed under reverse pressure.
Specific methods such as backwashing or reverse blowing can be used to clean the filter cartridge and remove the filter cake from its surface.
After cleaning, the filter cartridge can be reused, extending its service life and reducing operational costs.

Lvyuan's product types and applications

Lvyuan specializes in the production of various filter cartridges, including sintered filter cartridges, stainless steel filter cartridges, plastic filter cartridges, powder sintered filter cartridges, copper sintered filter cartridges, and pneumatic component sintered filter cartridges, which can be used in round tube filter cartridges, non-standard filter cartridges, covers, and copper sintered filter cartridges.

Sintered copper filter cartridges and copper-based sintered filter cartridges are professionally manufactured by Lvyuan, belonging to high-temperature and high-pressure resistant filter cartridges. The industry commonly uses spherical tin bronze powder as raw material, which is molded, heated and sintered in a sintering furnace, and then demolded to obtain filter elements of the desired shape and size.

Pneumatic filter elements utilize various materials, such as sintered powder alloys and porous powder filter elements; hydraulic oil filtration employs copper-based sintered filter tubes; and noise reduction and explosion-proof applications use explosion-proof discs. Lvyuan provides customers with suitable sintered copper filter elements and copper-based sintered filter elements based on specific requirements.

Lvyuan specializes in the production of various copper-based sintered filter cores, filter plates, pneumatic components, sound-damping check valve filters, oil-impregnated bearings, and other air source treatment components. In 2009, we successively developed polyethylene plastic filter cores and high-precision filter cores.

The products are primarily used for filtering and noise reduction of substances such as air, water, and oil, thereby improving their quality. The company adheres to the principles of integrity, quality first, and continuous improvement. We welcome inquiries for pricing.
