Fuel Water Separator Test Bench

The Fuel Water Separator Test Bench primarily follows ISO/TS 16332-2006 "Diesel engines - Diesel filters - Evaluation of fuel-water separation performance" to test the oil-water separation characteristics of the fuel filter; and performs a cleanliness test on the fuel filter using ISO 4020-2001 "Road vehicles - Fuel filters for diesel engines". The main technical parameters displayed are: test flow rate, system pressure, orifice plate device pressure difference, test specimen pressure difference, and medium temperature.

Applications

The Fuel Water Separator Test Bench is designed to evaluate the water separation performance and cleanliness of fuel filters used in diesel engines. Typical applications include:

Development of new fuel filter products

Comparative performance testing against international products

Quality control during production

Third-party testing and regulatory inspection

The system simulates fuel flow conditions and measures water separation efficiency, differential pressure, system pressure, and cleanliness to ensure accurate filter performance evaluation.

Standards

ISO/TS 16332-2006 – Method for evaluating fuel water separation efficiency of diesel engine fuel filters

ISO 4020-2001 – Road vehicles – Fuel filter test methods for diesel engines

SAE J905-1999 – Diesel fuel filter test methods

Features

Automated Data Acquisition: Key performance parameters such as flow rate, pressure, and differential pressure are automatically recorded

Variable Flow Control: Flow rate regulated using a frequency converter for precise adjustment

Comprehensive Protection: Includes hydraulic protection, electrical protection (leakage, overload), and emergency stop functionality

Robust Construction: Aluminum alloy frame, stainless steel panel with engraved markings, and seamless stainless steel piping ensure durability

Customizable Design: Parameters can be tailored according to customer requirements

Technical Parameters

Accessoriess

The test bench mainly consists of six parts: a test circulation system, a water injection system, a test auxiliary system, an online laser particle size analyzer, a Karl Fischer titrator, a real-time temperature control system, an electrical control system, and a test bench frame.

Test Procedures

1. Preparation Phase

Check the equipment power supply, air supply (if available), and pipeline connections for proper functioning;

Configure the test fuel-water mixture according to the testing requirements (in proportions conforming to the corresponding standards);

Install the fuel filter to be tested onto the filter interface of the test bench, ensuring a leak-free seal.

2. Parameter Setting

Select the corresponding test standard (e.g., ISO/TS 16332) through the operating interface;

Set the test parameters:

Fuel flow rate (simulating actual operating flow rate);

System pressure/differential pressure threshold range;

Test duration (set as needed).

3. Test Operation

Start the equipment and allow the fuel-water mixture to circulate through the filter at the set flow rate;

The equipment automatically monitors and records data such as water separation efficiency, differential pressure, and system pressure;

Observe the equipment's operating status during the process, and immediately stop if any abnormalities occur (e.g., leakage, excessive pressure).

4. Post-Test Processing

Stop operation, close pipeline valves, and drain residual fuel-water mixture;

Remove the filter under test and clean the test bench pipelines;

Export and analyze test data, and generate a test report.
