Test Procedures

1. Preliminary Preparation

Check the connections and seals of all equipment components (oil tank, circulating pump, pipelines) to ensure there are no leaks; Add hydraulic oil meeting test requirements to the working oil tank, and add contaminant powder according to standards (e.g., GJB1003:1996) to prepare a medium with the specified contaminant concentration.

2. Equipment Start-up and Parameter Setting

Connect the AC 380V/50Hz power supply and turn on the agitator to homogenize the contaminant medium; Start the circulating pump and activate the cooling function to circulate the medium within the system and stabilize its temperature; Set the test parameters (e.g., test pressure, flow rate, running time, etc.) through the control panel.

3. Test Operation

Secure the hydraulic pump to be tested to the pump housing and connect it to the test pipeline; Start the test program, allowing the hydraulic pump to run in the contaminant medium. Monitor the flow rate using a flow measurement device (manually switched by a valve), and simultaneously record the pump's pressure, temperature, and other operating data.

4. Post-Test Processing

After the test, first shut down the hydraulic pump, then stop the circulation pump and agitator;

Remove the test pump and observe its wear, or retest the pump's performance (e.g., flow rate, pressure stability);

Clean the test medium and clean the oil tank, pipelines, and other components.

5. Data Processing and Equipment Cleanup

Process the parameters recorded during the test and analyze the hydraulic pump's anti-contamination performance;

Turn off the equipment power and complete the equipment cleaning and maintenance records.
