Title of the articleTechnical methods of changing the consumption coefficient of suction holes of various configurations
Abstract.Problem statememt. The purpose of the work is to develop technical methods for changing the consumption coefficient of suction holes of various configurations. Results. The high efficiency of the suction devices depends on the accuracy of their calculation, which ensures a given volume of air being removed. The air flow rate is regulated by the air intake area by changing the consumption coefficient of the suction holes. Accurate values of the consumption coefficients of suction holes of various configurations are obtained. Conclusions. Significance for the construction industry lies in the fact that the obtained values of coefficients of flow of suction holes of different shapes allow you to calculate the air receiver device of any geometry and purpose.
Keywords.suction air line, hole, internal screen, flow coefficient.
