1. Pre-Test Preparations (After Maintenance)
Remove all debris from the pump base and surrounding area. Ensure the site is clean and tidy.
Verify that valves open and close smoothly.
Check instrument responsiveness and clean all pipelines.
Inspect the slurry pump assembly and ensure all motor and base anchor bolts are securely tightened.
Confirm that sealing components meet specifications.
Inspect the cooling pump casing for integrity and proper flow.
Refill the lubrication system with the specified oil as per regulations.
Test the motor in no-load condition to confirm proper rotation direction.
Align and connect the coupling after verification.
2. Test Run Procedures
Rotate the pump manually for two full turns to check for unusual noises or blockages.
Reinstall the protective cover after inspection.
Fill the pump chamber with liquid and ensure all air is purged from the system.
Start the pump according to standard operating procedures.
Conduct a continuous test run for at least 2 hours under normal operating conditions.
Smooth operation with no vibration.
Effective cooling and lubrication.
Bearing temperature within allowable limits.
No leakage from seals.
Flow rate and head pressure must meet production requirements.
Motor current must not exceed the rated value.
Ensure all maintenance records are complete and accurate.
Complete the acceptance documentation after a successful test run.
3. Safety Precautions
The test run must be conducted in an organized manner, with a dedicated safety supervisor.
Only certified operators are permitted to start or stop the slurry pump.
Strictly follow the startup and shutdown procedures.
If abnormal noises, leaks, or other irregularities are detected, stop the pump immediately.
Investigate and resolve the issue before resuming the test run.
Complete the test run log and acceptance form after the test.
