The Oil Filter Performance Tester evaluates the durability, efficiency, and fatigue resistance of hydraulic and lubrication filters under repeated operational cycles. Using the principle of "multiple passes through," components undergo a controlled number of cycles to simulate long-term use. This accelerated testing allows objective assessment of filtration performance, particle removal efficiency, and structural integrity.
Applications include hydraulic filter testing, fastener fatigue testing, shoe bending evaluation, and flow fatigue analysis. Performance parameters are measured at intervals or at the end of the test, with failure criteria defined based on performance changes, appearance, or structural integrity.
(1) Hydraulic filter manufacturing: Evaluate filtration efficiency and dirt holding capacity over repeated cycles.
(2) Automotive and industrial components: Assess fatigue resistance of hoses, connectors, and fasteners.
(3) Research & Development: Optimize product durability and lifespan.
(4) Quality Control: Ensure batch-to-batch consistency of filters and components.
(5) Laboratory testing: Standardized evaluation of performance degradation under controlled conditions.
