Oil Filter Hydrostatic Breakage Tester

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.

Applications

The Oil Filter Hydrostatic Breakage Tester is a test bench independently developed and manufactured by our company. It is used to determine the static pressure and rupture pressure values that the oil filter can withstand.

Standards

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.

Technical Parameters

Accessoriess

1. Core Testing Components

Filter Element Test Fixture (Compatible with different filter element specifications): Used to fix the filter element, allowing switching between "external pressure collapse" and "internal pressure rupture" pressure application directions.

Filter Housing Test Fixture (Compatible with different housing sizes): Seals and fixes the complete filter housing, supporting the housing rupture pressure test.

High-Pressure Hydraulic Line (High-Pressure Resistant Material): Transmits the test medium and withstands high-pressure conditions during the test.

2. Functional Auxiliary Components

High-Precision Pressure Sensor: Monitors test pressure in real time, synchronously feeds back data, and triggers fault detection (such as sudden pressure drop).

Explosion-Proof Transparent Protective Cover: Isolates the sample during testing, preventing media and fragments from splashing during rupture, ensuring operational safety.

High-Pressure Hydraulic Pump with Pressure Regulator Module: Provides stable and controllable pressure output, gradually increasing pressure at a set rate.

Digital Display Controller: Used to configure test parameters, display pressure data in real time, and record the maximum pressure value at the time of sample rupture.

3. Consumables and Auxiliary Components

Test Medium (Hydraulic Oil/Special Test Fluid): As the pressure transmission medium, it must match the requirements of the corresponding test standard. Oil-resistant/high-pressure sealing gaskets: ensure the sealing effect of test fixtures, samples and pipelines, and prevent pressure leakage from affecting test accuracy.

Test Procedures

1. Preparation Stage

Equipment & Sample Setup

Connect the tester to a stable power supply, and fill the liquid medium (hydraulic oil or specified test fluid) into the test circuit.

Select the test mode (Filter Element Collapse/Burst or Filter Housing Burst) based on the test target:

For element testing: Install the filter element into the fixture, and confirm the pressure direction (outside-in for collapse, inside-out for burst).

For housing testing: Secure the complete filter housing to the test station, ensuring a sealed connection.

Safety Check

Close the transparent protective cover (to prevent splashing during rupture), and verify that the pressure sensor and failure detection system are functioning normally.

2. Parameter Configuration

Turn on the instrument, set the pressure increase rate (controlled rate per standard requirements) via the control panel.

Set the pressure monitoring threshold (for automatic failure detection, e.g., trigger on sudden pressure drop).

3. Test Operation

Start the high-pressure hydraulic pump to gradually apply pressure to the test sample (filter element/housing).

Monitor the digital pressure display in real time; the system will track pressure changes continuously.

When the sample fails (e.g., pleat collapse, seam rupture, housing rupture), the failure detection system will trigger (via pressure drop/audible event), and the instrument will record the maximum pressure reached (collapse/burst pressure).

Stop the pressure supply immediately after failure is detected.

4. Post-Test Process

Release the residual pressure in the test circuit slowly.

Open the protective cover, remove the damaged test sample, and clean the test fixture/inner chamber.

Export the test data (recorded burst pressure) and generate a test report.
