Filtration Element Unit With Non Return Valve · 模型 170671
Advanced Technology Overview: The filter element unit with non-return valve is an integrated hydraulic filtration system designed to protect hydraulic systems while ensuring continuous operation even in the event of filter clogging. This unit combines micro-filtration technology with the critical safety function of a bypass valve with a non-return valve to prevent reverse flow. Main Structural Components: 1. Core Filtration Element: Multi-layer structure: Layer 1: External support mesh - 304 stainless steel (mechanical protection) Layer 2: Primary filtration medium - glass fibers (25 microns) Layer 3: Main filter medium - Microfiber (3-10 microns) Layer 4: Internal support mesh - (prevents element collapse) Layer 5: Structural core - Perforated steel tube Technical specifications: Filter material: Glass fiber treated with resin sheet Filtration grade: 3, 6, 10, 25 microns (customizable) Filtration efficiency: βₓ ≥ 200 according to ISO 16889 Retention capacity: 100-500 grams depending on size Filtration area: 0.5-2.0 m² depending on model Flow resistance: 0.5-2.0 bar at rated flow 2. Bypass Valve: Intelligent mechanical design: Working principle: When ΔP > P_set → bypass valve opens When ΔP < P_set → bypass valve closes Where: ΔP = pressure difference across the element P_set = opening pressure setting (adjustable) Technical Specifications: Valve Type: Spring-loaded with fine adjustment Pressure Adjustment Range: 1.0 - 4.0 bar Adjustment Accuracy: ±0.2 bar Spring material: 302/304 stainless steel Response speed: < 100 ms Service life: > 1,000,000 cycles Bypass valve operating conditions: Normal condition (filter operation): Pressure: ΔP < P_set Status: Valve closed Path: Oil → Filter element → Outlet Efficiency: Full filtration Bypass condition (clogged filter): Pressure: ΔP ≥ P_set Status: Valve open Path: Oil → Bypass valve → Outlet Protection: Continuous operation Transitional state: Pressure: ΔP ≈ P_set Condition: Partial valve Path: Oil divided between two paths Function: Prevent hydraulic shocks 3. Non-Return Valve: Versatile design: Design types: 1. Ball Check Valve 2. Swing Check Valve 3. Flapper Check Valve 4. Spring-assisted Check Valve Technical specifications: Opening pressure: 0.1 - 0.5 bar Closing pressure: ≈ 0 bar Ball/feather material: chrome steel or coated nitrile Seat material: nitrile or polyurethane Closing time: < 50 ms Leakage rate: < 1 drop/min at 10 bar
