Reason for reduced output and vibrations in centrifugal pumps

Causes of reduced output of a centrifugal pump: worn wear ring,choked suction filter, air sucking in, lack of
priming, cavitation,improper maintenance.causes of vibration : misalignment of shaft, worn bearings, loose foundation bolts, worn or corroded parts, improper clearances

Why atomisation test should not be done in slide type fuel valves

Since very small needle lift is obtained in the test equipment result in an unequal pressure distribution in the cut off shaft resulting in a hard contact in a small area along with high frequency oscillations, low lubricity of test oil will increase the chance of seizure. Full lift and high lubricity of heavy oil eliminates this risk  of seizure during normal operation.( Always open and clean slide type valves before testing as cold sticky heavy oil along with small clearances can cause restriction in the movement of the spindle).
