Oil Filter Hydrostatic Breakage Tester

Melakukan standar:

ISO 2941

SAE J1858

Product Introduction:

The Oil Filter Hydrostatic Breakage Tester operates by using a liquid medium (typically hydraulic oil or a specified test fluid) to apply pressure to the filter component under evaluation. The test can be configured to assess different failure modes:

Filter Element Collapse/Burst: The filter element is placed in a test fixture, and a differential pressure is applied across the filter media from the outside-in (collapse) or inside-out (burst). The pressure is steadily increased at a controlled rate until the element's structure fails (e.g., pleat collapse, seam rupture, end cap separation).

Filter Housing Burst: The filter housing is subjected to increasing internal hydrostatic pressure until it ruptures or permanently deforms beyond acceptable limits.

A high-pressure hydraulic pump or pressure source is used to generate the test pressure. The pressure is monitored by a transducer and typically displayed digitally. A failure detection system identifies when the structural integrity is compromised, often marked by a sudden pressure drop, audible event, or visual observation, and the maximum pressure reached is recorded as the collapse, burst, or rupture pressure. This test is a critical part of filter qualification and quality control processes to ensure filters meet their specified pressure ratings and can safely operate within a given system.

The instrument is used for:

Determining the collapse or burst pressure rating of filter elements.

Verifying the burst pressure rating of filter housings.

Quality control during the manufacturing of filter elements and housings.

Evaluating the structural effects of material changes or design modifications on filter integrity.

Investigating structural failures of filters from field use.

Ensuring compliance with relevant industry standards and OEM specifications for filter strength.

Product Advantages:

Provides objective, quantitative data on the structural limits of oil filters under pressure.

Directly verifies the collapse, burst, or rupture pressure rating of filter elements and housings.

Essential for preventing catastrophic filter failures in hydraulic and lubrication systems.

Helps ensure the safety and reliability of equipment by confirming filter structural integrity.

Standard compliant test methods are widely available and recognized (ISO 2941 is a key standard).

Allows for controlled and repeatable testing under defined conditions.

Crucial for quality control and design validation processes.

Product Features:

High-pressure hydraulic power unit (pump) or pressure source capable of generating pressures up to the maximum required test pressure.

Pressure control system to increase the test pressure at a precise, controlled rate as specified by test standards.

Robust test stand or fixture designed to securely hold the filter element (for collapse/burst tests) or the filter housing (for burst tests) and withstand the applied pressure.

High-accuracy pressure transducer to measure the applied hydrostatic pressure.

Failure detection system that automatically identifies when the filter structure fails and records the pressure at failure. This may involve monitoring pressure drop, using acoustic sensors, or relying on visual confirmation in some cases (though automation is preferred for accuracy).

Safety enclosure or shielding constructed from strong materials to contain test fluid and debris in the event of a violent rupture.

Digital display showing the applied pressure, pressure rate, and the recorded failure pressure.

Controls for starting, stopping, and pausing the test.

System for filling the filter or housing with the test fluid and purging air.
