On the basis of a qualitative analysis of the structure and principle of operation of a parametric single-stage pressure pulse generator with adjustable pressure "closing" p2, the design of a prototype of the generator was developed. The article describes the principle of operation of the developed structure and describes the design of structural elements and their interaction with other structural elements from the justification. The design calculation methodology is developed on the basis of generally accepted engineering and scientific principles and experience in the design and operation of equipment based on pneumatic and hydropulse drive of vibration and vibration shock machines. The paper presents a sample of initial data that is necessary for the development of a design calculation methodology for a parametric single-stage pressure pulse generator with adjustable "closing" pressure p2.
Based on the analysis of the design of the prototype of the generator, the accepted initial (input) data and the experience of designing a hydropulse drive and pressure pulse generators given in the literature sources, a method of design calculation of a parametric single-stage pressure pulse generator with adjustable pressure "closing" p2 has been developed and its main energy, power and geometric parameters of the design of the prototype of both a hydropulse drive and a generator have been determined pressure pulses. The presented mathematical dependencies allow you to change the parameters of the pressure pulse generator to the corresponding technical and economic parameters of the technological process.
The paper also substantiates the use of the concept of "cyclic pressure pulse coefficient", the exact value of which can be found only based on the results of experimental studies of a prototype of a pressure pulse generator. For the design calculation, based on the recommendations of the researchers of the hydropulse drive, a margin factor within 10 ... 25 percent of the face value.
