Technical Parameters

Accessoriess

Standard configuration: Main unit, miniature printer, air supply connection pipe, hydraulic leak-proof device

Note: The air source interface of this machine uses an 8mm polyurethane tube; the air source must be provided by the user.

Test Procedures

1. Preparation Before Operation

Equipment and Environment Check:

Confirm that the instrument's power supply (wide voltage adaptable) and gas line interfaces (Φ8mm polyurethane tubing) are in normal condition; place the equipment on a ventilated, temperature-stable (20±5℃) workbench, ensuring no airflow interference.

Sample and Consumable Preparation:

Prepare the fluid system components to be tested (e.g., pipes, valves, sensors), ensuring the components are clean and undamaged; prepare a suitable gas source (provided by the user, pressure ≤0.7MPa).

Standard Matching:

Confirm the standards that the test needs to comply with, and clarify the pressure and flow rate test indicators.

2. Equipment Calibration

Start the instrument and access the "Calibration Interface" via the color touch screen;

Perform automatic calibration of the pressure sensor (according to 0.5% FS accuracy requirements) and flow module (supported by some models), or perform manual calibration using a standard pressure/flow source to ensure test accuracy.

3. Parameter Settings

Select the corresponding standard on the touch screen interface;

Set test parameters:

Pressure test range: Default 0-10KPa (customizable as needed);

Flow rate test range: Match the actual flow rate range of the component under test;

Test duration: Set the continuous test cycle according to the component characteristics.

4. Sample Installation

Connect the fluid components to be tested (e.g., pipes, valves) to the input/output terminals of the instrument via standard gas line interfaces (Φ8mm polyurethane tubing);

Check the connection for airtightness (to avoid air leaks affecting test results), ensuring the components are securely installed and not twisted.

5. Test Execution

After confirming that the parameters and sample installation are correct, click "Start Test";

The instrument automatically runs according to the set parameters: controlling the gas source pressure transmission, synchronously collecting flow rate data, and recording indicators such as pressure transmission efficiency and flow characteristics in real time;

Monitor the data curve via the touch screen during the test. If any abnormalities occur (e.g., pressure/flow rate fluctuations exceeding limits), the test can be paused to troubleshoot the problem.

6. Data Processing and Report Generation

After the test is completed, the instrument automatically stores the real-time data;

Export a test report containing "pressure transmission data, flow characteristic curves, and compliance with standard judgment" for:

Fluid system performance evaluation: verifying whether the system meets design/usage requirements;

Product quality control: checking whether the component quality meets industry standards.

7. Post-Test Maintenance

Disconnect the air supply and power, remove the tested component, and clean any remaining impurities from the air circuit connections;

Record the instrument's operating status, and regularly re-check and calibrate it to ensure long-term stable operation of the equipment.
