Q: What does a pressure line filter do?

The core function of pressure pipeline filters is to intercept fluid impurities installed in high-pressure pipelines, prevent downstream precision components from wearing, getting stuck or blocked, and ensure stable system operation. ‌‌

Core functionality

• Removing impurities: intercepting solid particles, colloids, carbon slag and other pollutants brought in by the outside world, generated by component wear or chemical changes in the medium.
• Protective components: Avoid premature wear, jamming, or blockage of throttle holes caused by pollution in high-precision control valves, servo valves, actuators, etc.
• Maintain system reliability: reduce downtime caused by malfunctions, extend the service life of hydraulic or process equipment, and ensure stable operation of automatic control systems and heavy machinery. ‌‌

Key features and application scenarios

1. High pressure resistant design: capable of withstanding pressure levels ranging from low pressure to 1000 bar, with a sturdy structure to adapt to pressure fluctuations.
2. High precision filtration: using glass fiber or stainless steel filter materials, with high pollutant holding capacity and low original pressure loss. Some models are equipped with bypass valves and pressure differential signaling devices.
3. Main fields: Widely used in military, mining, metallurgy, engineering machinery, and servo hydraulic systems that require extremely high cleanliness. ‌‌

Q: What is a pressure filter?

A pressure filter is a solid-liquid separation device that uses external pressure to drive fluid through a filter layer in a sealed pressure tank to trap impurities. It is widely used in water treatment and industrial pipeline systems. ‌‌

Core Definition and Characteristics

• Essence: A mechanical filter (also known as a pressure filter or cleaner), with a closed steel or fiberglass tank shell and filled with media such as quartz sand, activated carbon, manganese sand, etc. inside.
• Power source: It relies on pumping or system pressure to create a pressure difference to push the fluid through the film/material, rather than gravity or vacuum.
• Main function: Remove suspended solids, colloids, organic matter, iron and manganese ions, reduce turbidity, and protect downstream equipment.
• Typical scenarios: Pre treatment of pure water preparation, industrial circulating water, purification of drinking water, and pipeline cleaning. ‌‌

Working principle and classification

Working principle: Raw water flows through the filter layer from top to bottom under pressure (usually 0.2-0.6MPa), and impurities are removed through screening interception, adsorption bridging, and contact coagulation mechanisms; After the resistance increases, the flux is restored through backwashing (water or air-water mixed backwashing).

Classified by medium:

Quartz sand/multi-media filter: for removing suspended solids and reducing turbidity;
Activated carbon filter: adsorbs organic matter, residual chlorine, and pigments;
According to pressure level: it can be divided into low pressure, medium pressure, and high pressure types, suitable for different industrial pipeline requirements (such as 25 bar to 450 bar). ‌‌
