With its basket - shaped filter screen structure and straight - through design, the basket strainer efficiently intercepts large - sized particles in pipeline fluids. Combining low - cost maintenance and high reliability, it serves as a fundamental protective device for industrial pipeline systems.
The basket filter is a small device that removes a small amount of solid particles in the liquid, which can protect the normal operation of the device. When the fluid enters the filter cartridge with a certain size filter screen, its impurities are blocked, and the clean filtrate is discharged from the filter outlet. When it needs to be cleaned, just take out the detachable filter cartridge and reload it after processing.
Fluid Inflow: The fluid to be filtered enters the strainer through the inlet and directly impacts the outer side of the basket - shaped filter screen.
Impurity Interception: The filter screen traps large - sized impurities such as rust, welding slag, and sand. The clean fluid passes through the mesh holes into the inner side of the screen and flows out through the outlet.
Maintenance and Cleaning: When the pressure difference between the inlet and outlet significantly increases (e.g., exceeds 0.1MPa) or during regular maintenance, close the upstream and downstream valves, open the top or side cover of the strainer, remove the filter screen, and clean the attached impurities using high - pressure water flushing or mechanical methods. Reinstall the screen after cleaning to resume operation.
| Key Advantages | Description |
|---|
| Efficient Coarse - filtration | Filter screen mesh size ranges from 10 - 500 mesh, effectively intercepting particles with a size of 1 - 20mm to protect downstream equipment. |
| Simple and Durable Structure | Made of carbon steel/stainless steel integrated housing with a detachable basket - shaped screen, corrosion - resistant and pressure - resistant (up to 16MPa). |
| Easy Maintenance | The screen can be removed without special tools. The cleaning cycle can be adjusted according to working conditions, with each maintenance taking less than 30 minutes. |
| Low - resistance Energy - saving Design | Straight - through fluid channel design with pressure loss <0.05MPa, reducing energy consumption and operating costs. |
| Flexible Installation Adaptability | Supports horizontal and vertical installation, suitable for pipeline diameters from DN25 - DN1200 to meet different system requirements. |
| Industry | Application Scenarios | Core Value |
|---|
| Petrochemical | Protection for pumps and compressors, process pipeline impurity filtration | Prevents mechanical impurities from damaging equipment, ensuring production continuity and product quality. |
| Power Industry | Steam pipeline and cooling water pipeline impurity interception | Avoids impurities blocking valves and heat exchangers, extends equipment lifespan, and reduces failure rates. |
| Water Supply and Drainage | Pump inlet filtration, municipal pipeline impurity removal | Protects pump impellers and pipeline fittings, reduces maintenance costs, and ensures stable water supply. |
| Food and Beverage | Raw material pipeline pre - treatment | Intercepts foreign objects, meets food safety standards, and improves product quality and production efficiency. |
How often does the basket strainer need to be cleaned?
It depends on the impurity content of the fluid, usually checked every 1 - 3 months. Immediate cleaning is required if the inlet - outlet pressure difference exceeds 0.1MPa.
Can it filter viscous liquids?
Medium - to low - viscosity liquids can be filtered by selecting a large - mesh screen (e.g., 10 - 20 mesh), but the cleaning frequency needs to be increased to prevent blockage.
What precautions should be taken during installation?
Ensure the flow arrow is consistent with the fluid direction during installation; regularly check the condition of the sealing gasket to prevent leakage; reserve space for screen removal when installing vertically.
The basket strainer stands out as an essential protective device for industrial pipeline systems, thanks to its simple and efficient interception performance, convenient maintenance, and wide applicability. Whether in high - load chemical production or municipal water supply with strict safety requirements, reliable impurity interception can be achieved through standardized selection or customized configurations. With the advancement of industrial pipeline system intelligence, the basket strainer will continue to optimize its structural design and monitoring functions, providing stable fluid protection solutions for more sectors.
