Abstract
Purpose. The purpose of the work is to increase energy efficiency of waterjet drilling holes in the sheet blanks and cell structures by new technical solutions of jet formation. Methodology. We have applied the mathematical simulation of waterjet drilling holes with the jet pulsed action application. The system of differential equations, describing the behavior of pulsed device, was solved by Runge-Kutta order 4 in the MathCAD software environment. Results. The research of the waterjet small diameter holes drilling efficiency by pulsed power supply shows that the improvement of the technology, which has been seen in the search of the hydraulic system rational schemes, parameters and modes and aimed to minimize the device power consumption losses. It has been shown the structure and working principle of connected waterjet cut off valve. It has been revealed the research of the time impact between opening slits valve stages and the waterjet head valve. It has been pointed out that the distributor opening is more rapid than the valve opening, at the same time as the spool valve position can cause unsteady movement that eventually lead to the two-phase jet fleeting breach formation. Originality. At first time it has been highlighted the ability to control transient acceleration process flow by opening high and low pressure hydraulic system valves. Practical value. The series of system hydromechanical behavior differential equations, allowing to identifying transients opening P2 and K1 slots and determine the conditions of increasing pressure in the respective hydraulic lines has been proposed.
