Establishment and Application of a Mathematic Model of Negative Pressure Equipment

Abstract:

This article constructs the characteristics equation of negative pressure nozzle (for DF), and on this foundation, analyses the separating flow ratio of NP equipment detail, thus obtaining its reasonable scope. Also the paper attempts to find relationship between section area ratio and separating flow ratio from the perspective of the characteristic equation of the nozzle. Based on the combination of the analysis and the principle of hydomechanics, the structure of traditional NP nozzle is modified according to the negative pressure gap, spray angle and separating flow ratio.
