Usually, The Centrifugal Pump Test Include Type Test and Factory Test:
The centrifugal pump test ─ type testing
Type test includes: running test, performance test and captivation test and noise vibration test, etc.
A: The running test
When running test, should check the temperature rise of pump bearing and packing, leakage of pump packing in vibration and noise.About the seal ring, balance disc, bearing wear and tear on the place such as in the test run Hangover Chad.
B: The performance test
Performance test is to determine the lift of pump, shaft power, the relationship between the efficiency and flow rate.Centrifugal pump starts from zero flow (at least) is greater than the measured using range is 15% of the maximum flow;Mixed flow pump, axial flow pump and vortex pump starting valve fully open, at least to 15% less than the minimum flow rate measurement.Measuring point should be uniform on the whole curve of centrifugal pump and vortex pump more than 13 points, axial flow pump, mixed-flow pump more than 15 points.
C: Cavitation test
Cavitation test used to determine the relationship between the critical cavitation allowance and flow.Or used to verify the critical cavitation allowance is less than or equal to the provisions of the pump of the necessary cavitation allowance.
The centrifugal pump test ─ the factory test
Factory test is used to check whether the performance of a centrifugal pump is conform to the requirements before they leave the factory .Factory test of centrifugal pump only commonly work within the scope of the small flow points, traffic, large flow points
More than three flow to test and check the pump head and power.
