LABORATORY TESTS OF A JET DEVICE TO INCREASE THE CENTRIFUGAL AND AXIAL PUMP SUCTION HEAD
Journal Title: Periódico Tchê Química - Year 2018, Vol 15, Issue 0
Abstract
The article is devoted to experimental laboratory studies to determine the value of the cavitational reserve of centrifugal pumps by installing jet devices in the suction line of pumping units powered by a recirculation line. The installation diagram with the location of equipment and instruments is shown. Literary sources were used to determine the optimal parameters of the jet apparatus according to the efficiency coefficient in determining the experimental data on the value of the cavitation reserve. The dimensions of the studied parameters of the jet apparatus and the magnitude of the pressures before and after the apparatus are taken as factors in the studies. The value of the cavitation stock Δh was taken as a criterion. According to the results of the studies using the experiment planning theory, empirical dependencies were obtained to determine the criteria in the intervals by which, at the optimum relative sizes of the jet apparatus, it is possible to determine the degree of increase in the cavitation stock at the optimal energy parameters for operating pumping stations.
